UL Label: all products shall be UL labeled assuring complete compliance with all specifications and requirements through continuous inspection by UL inspectors.

Fire Detection Characteristics: The vinyl wallcovering shall contain the Early Warning Effect formulation which provides early warning to potential fire conditions. The vinyl wallcovering shall contain thermoparticulating ingredients which, when heated to approximately 300F emit a colorless, odorless vapor that activates ionization smoke detectors when installed according to manufacturer’s specifications. Evidence of the Early Warning Effect shall be based on the ASTM E603 standard guide for room fire experiments.

Protective Coating: The vinyl wallcovering shall have a protective coating applied to its surface to minimize migration of stains into the vinyl and, therefore, offer stain protection from a variety of staining agents and provide greater ease of cleanability.

Adhesive: the adhesive used must be manufacturer’s recommended adhesive and must contain mildew inhibitors.

Primers: The primer used must be manufacturer’s recommended primer.

Inspection: Installer shall inspect all areas and conditions under which vinyl wallcoverings are to be installed. Installer shall notify the contractor and architect in writing of any conditions detrimental to the proper and timely completion of the installation; work will proceed only when conditions have been corrected and accepted by the installer.

Substrate shall be checked with a suitable “Moisture Meter”. Moisture shall not exceed 4%.

Surface Preparation: Wall surfaces shall be free from defects and imperfections that could show through the finished covered surface.

Sand-finished plaster shall be smoothed, cinder or cement blocks shall be plastered, or otherwise rendered smooth, and old wallcoverings shall be removed.

For new drywall construction, manufacturer’s recommended primer should be used before application of wallcovering for ease of future removal when redecorating.

Glossy surfaces shall either be sanded to dull surface, or a coat of manufacturer’s recommended primer applied prior to installation of wallcovering.

If there is any evidence of mildew, it must be removed and the wall surface treated to inhibit further mildew growth.

All painted surfaces should be evaluated for the possibility of pigment bleed-through. If there is any possibility, a coat of sealer, recommended by the manufacturer, should be applied before application of the wallcovering.

Do not install vinyl wallcovering over oil-based wood stains as a bleed-through may occur.

Installation: Wallcovering shall be installed by experienced workers and contractors in strict accordance with the manufacturer’s printed instructions using vinyl wallcovering adhesive recommended by the manufacturer (WHEAT PASTE SHALL NOT BE USED). It is absolutely imperative that installer read the manufacturer’s instruction sheet in each roll before installing the vinyl wallcovering. Permanent building light shall be available for installation.

Installer, before cutting, shall examine pattern and color and determine that they are the correct pattern and color as specified.

Installer shall install each roll in sequence starting with largest roll number and each strip in same sequence as cut from roll. If pattern is not random, examine for repeat design. Some patterns should be lined up, matched or reversed for best results. If necessary, trim selvage deep enough to assure color uniformity.

After application of three strips, an inspection should be made and if there are any variations in color or pattern which are felt to be excessive, the wallcovering distributor or manufacturer’s representative should be notified for his inspection before any further wallcovering is installed.

Always bring material six (6) inches around inside and outside corners being sure to fir into corners to avoid bridging or spanning.

The wallcovering should be smoothed to the hanging surface with a stiff bristled sweep brush or a flexible broad-knife to eliminate air bubbles.

Remove excess adhesive along finished seam immediately after each wallcovering strip is applied. Use of clean, warm water, a natural sponge and clean towels are recommended for this use. It is very important to change water often to maintain cleanliness.

Clean-up Completion: Upon completion of work, remove surplus materials, rubbish and debris, resulting from the wallcovering installation. Leave areas in neat, clean and orderly condition.

Manufacturer – Mannington Commercial

Roll Widths:

Because Mannington Commercial Resilient Sheet Flooring products are intended for use in high-traffic areas, underfloor selection and preparation are especially important. In most cases, remove all existing floor coverings before installing these commercial products. (You must strictly follow all federal, state, and local regulations regarding the removal of existing flooring). Furthermore, all concrete under floors must be tested for moisture before starting the installation. Mannington requires that the concrete be tested for moisture suing either the anhydrous calcium chloride test following ASTM F 1869 procedures or the in-situ relative humidity test following ASTM F 2170. Maximum permissible MVER are determined by product construction and adhesive type (see chart above). NOTE: While either of these industry accepted moisture testing methods may be used, the results are not exchangeable, if both tests are performed they must both be in the acceptable range to be considered valid.

Handling Procedures: It is imperative to maintain the material, adhesive, and job site at a minimum temperature of 65 F and a maximum temperature of 85 F for 48 hours before, during, and after the installation. If the material has been stored at colder temperatures, it needs to be unrolled and allowed to relax overnight before proceeding with the installation. When using V-95 adhesive, make sure to maintain the adhesive, floor covering, and job site at a minimum temperature of 65 F for a minimum of 48 hours before, during, and after the installation.

Patching and Leveling Compounds: We recommend the use of latex/Portland cement trowelable underlayments of self-leveling cementitious products for repairing or leveling concrete subfloors. Sand and fill approved underlayment panel joints using a latex/Portland cement compound. The properties and handling characteristics of Mannington MVP 2023 Fast Patch make it an ideal compound for use under Mannington Commercial Resilient sheet flooring products. Do not use gypsum or mineral-based patching compounds in commercial applications under any circumstances.

Cutting and Fitting: Mannington Commercial inlaid products are flexible and will handle easily when cutting and fitting. This product characteristic enables the installer to fit the material using freehand knifing techniques/

· If the job site is complex and requires a precise fit, use pattern-scribing techniques.

· The material may also be fit using direct scribing techniques (Refer to Mannington’s Professional Installation Handbook for pattern scribing and direct scribing).

· Once the material has been fit, it is necessary to tube or lap back half of the sheet to expose the underfloor for adhesive application.

· Take care when folding the material back. Always fold the material in a wide radius to avoid sharp kinks and creases, which may cause breaks in the product.

Applying Adhesive: Fully Adhere Mannington Commercial resilient sheet flooring to an approved underfloor.

· After you have trimmed the material to fit the room, tube or lap it back to expose the underfloor. Apply adhesive with the recommended notched trowels found in the adhesive label.

· Spread adhesive over 100% of the exposed subfloor, leaving no gaps or puddles.

· Maintain uniform coverage by keeping the trowel clean and properly notched.

· In most cases it is advisable to give the adhesive sufficient open time. Open time allows the moisture to flash off the adhesive, permitting the adhesive to develop more body and immediate tack. Open time is always determined by subfloor porosity and atmospheric conditions. Be certain to provide ample open time on non-porous subfloors and at seam lines.

· After the adhesive has begun to tack-up, roll the sheet forward into the adhesive to avoid trapping air. Do not drop or flop the material into the adhesive. Roll the floor covering with a three-section, 100 lb (or heavier) floor roller in both directions.

· After the first half of the sheet has been adhered and rolled, fold back the second half and repeat the procedure.

CAUTIONS:

· When providing open time, do not permit the adhesive to ‘skin over’ or dry. Too much open time will result in insufficient bonding.

· BioSpec MD and LifeLines II should be installed using V-82 adhesive over porous substrates. Use V-95 adhesive over non-porous substrates. M-Guard V-88 may be used over both porous and non-porous subfloors.

· Mannington V-95 adhesive has low initial tack. It may be necessary to apply weights to the floor covering especially in the seam area, until the adhesive sets. When using V-95 adhesive, roll the adhered flooring with a 100 lb (or heavier) floor roller within one hour after the flooring is installed.

· Wait one to two hours and re-roll the flooring again to ensure full contact has been achieved. Re-rolling the material will also help remove any trapped air bubbles.

Seam Cutting and Seam Sealing:

Double-cutting Seams: Aberdeen Collection and Insight Plus

1. If required to seam Aberdeen Collection of Insight Plus products, provide additional length on the second and succeeding sheets to allow for proper pattern alignment

2. Position Aberdeen Collection and Insight Plus floors using the “Reverse” or “Do not Reverse” method.

3. To minimize pattern run-out, the floor covering should always be laid out minimizing the length of the seams.

4. Cut material to the appropriate sizes that day before the actual installation.

5. Store the material at recommended temperatures.

6. Roll these cuts tightly, face-out around a core, maintaining as equal a diameter as possible.

7. Cut and install the pieces in sequential order. If the job requires more than one roll of floor covering, make sure all rolls are marked with the same shade letter and that the roll serial numbers are in consecutive order.

8. After aligning the pattern and providing adequate overlap, adhere the sheets of material up to the predestinated dry zone.

9. Cut the seam using a utility knife with a new, sharp blade. Using a steel straightedge, cut through both sheets of flooring at a 90 angle to the floor covering.

10. Once you have cut the seam, remove the selvage and fold back the sheets to expose the dry zone.

11. Apply adhesive with a properly notched trowel across the dry zone.

12. Allow the adhesive to develop tack and lay the sheet that was on the bottom during the cutting process into the adhesive first.

13. Then place the top sheet into the adhesive; avoid scraping adhesive into the cut. Roll the area with the three-section floor roller.

14. Bring seam edges level with the use of a hand seam roller.

15. Thoroughly clean the seam area and wipe dry. For a more detailed and photographed description, see Mannington’s Professional Installation Handbook.

Heat Welding: Heat welding is the act of fusing resilient sheets together with a heated thermal vinyl weld rod. This technique is suitable for installing the following Mannington Commercial resilient sheet flooring products: Fine Fields, LifeLines II, BioSpec MD, Magna, and Mannington Assurance II. Never use heat welding on Mannington resilient products, Aberdeen Collection or Insight Plus.

NOTE: Heat welding is the preferred method of sealing seams for homogeneous products.

Weld Rods: Mannington’s weld rod is available on spools and is designed to fit the most popular heat welding guns. Mannington offers a broad range of solid rod colors to coordinate with all of our heat-weldable flooring. Camouflage weld rods are offered for Fine Fields and BioSpec MD.

Heat Welding Recommendations: To achieve good sealing results, knowledge of proper heat welding procedures is important.

· A repeated stop / start method will produce rough uneven seams, creating an unpleasant appearance.

· Temperature setting is critical to the success of any heat welding application. If the welding gun is set too hot or applied too slowly, the flooring is likely to burn, char, or craze the surface next to the weld rod. If welding gun is not hot enough or applied too quickly, the weld may have poor fusion. Follow all Mannington temperature requirements to achieve an even seam with good bond strength and integrity.

· After waiting 24 hours for the adhesive to dry, use a power-grooving machine to cut a groove the entire length of the seam. Adjust the machine so the depth of the groove is about two thirds of the product’s thickness. Stop machine grooving several inches away from the wall.

· Extend the groove to the wall using a hand-grooving tool.

· Prior to heat welding, allow the flooring adhesive to completely dry. Preheat welding gun and determine proper temperature setting and router depth by practicing on scrap pieces of flooring. Make certain the speed nozzle is clean and free of obstructions.

· Insert welding rod into the speed nozzle allowing approximately 3” to extend out. Arrange welding rod in such a manner that it will not interfere with the application. Be careful when inserting the welding rod because the nozzle is extremely hot.

· Pull the gun along the length of the seam toward your body while maintaining a downward pressure. Keep the gun perpendicular to the floor. Weld the seam at a constant, even speed.

· Stop and change direction of the weld when you are near the back wall. Pull the gun out of the groove and cut the weld rod.

· Remove the urethane coating before heat welding inside corner by grooving or sanding. Performed metal corner caps may also be used.

· Allow welded rod to cool, and then groove the installed rod with a hand-grooving tool. Grooving the rod makes it possible to achieve complete seam coverage when you start seaming from the opposite direction to finish the job. Reposition yourself and your tools at the back wall and continue welding into the grooved rod you just made so there are no missed spots in the seam. It is important to achieve a smooth, continuous coverage fo the rod into the seam.

· After the welded rod shrinks and cools for approximately 30 minutes, trim down the excess by using the following two steps: Remove approximately two thirds of the exposed welded rod. Use a spatula trim knife and trim plate to trim off the top layer. There should be about 1/32” excel weld rod projected above the surface of the resilient.

CAUTION: when trimming weld rods on Mannington Assurance II, do not allow weld rod to cool.

· The second step is to trim the welded rod level until it is flush with the surface of the resilient sheet. Use an extremely sharp spatula knife without the trim place at a 5 to 10 angle to the floor surface. Keep the sharpened side down against the welded rod. Be careful not to cut or dig into the resilient surface. Inspect the finished seam carefully and remove any missed high spots with a spatula knife. If there are low spots, the seam weld may require a rod reapplication.

· Once the entire area has been trimmed and inspected, smooth out seam with one of the two recommended methods. When using camouflage weld rods, both steps are required:

· Glaze Curing the Seam: apply heat from the welding tool by removing speed nozzle and using the same heat setting to direct a flow of heat from the gun along the length of the seam.

· Seam Sealing the Seam: to smooth out the seam, apply MCS 42 seam sealer to the welded seam and leave it on no longer than 30 to 40 seconds. Wipe all sealer from the surface of the seam with a clean white cloth dampened with mineral spirits. Do not wipe the seams of camouflage weld rods. Allow the sealer to be absorbed into the rod. Both of these last steps reduce porosity of the trimmed rod and glaze the surface of the welded rod to produce a smooth, continuous appearance.

· When the delayed maintenance procedure is used the glazed weld rod should be protected by applying a uniform coating from QGHP marker. This antimicrobial, protective coating will keep the seam area clean.

Finishing and Maintenance: Protect all exposed edges of floor covering with trim or restrictive moldings.

· Remove all scraps and trash from the jobsite.

· Remove all adhesive smears or residue from the surface of the floor covering with a clean cloth dampened with mineral spirits.

· After 24 hours of the completed installation, thoroughly clean the floor.

Repairs: Replacing damaged areas

· If possible, the floor covering repair piece should come from the original installation. Typically, consumers retain leftover pieces from the original installation.

· Tape the repair piece over the damaged area and double-cut using a steel square as a guide.

· Remove the damaged area and scrape the subfloor clean. Apply adhesive on the back of the repair piece and insert into the flooring.

· Roll the repair piece with a hand seam roller.

· Use the appropriate Mannington seam sealer to seal all cuts.

Flash coving Resilient Sheet Products: All Mannington resilient sheet goods can be installed using the flash coving method. This edging technique, often referred by hospitals and other health care facilities, is a process of extending the resilient flooring up the wall to create a wall base. Normally, the floor covering is extended up the wall to a height of 4” to 6”. Coving is popular with end users because it eliminates the need for a floor /wall juncture and it is also easy to maintain.

As with all resilient installations, proper preparation of the work area is critical to the success of the installation. Clean the underfloor carefully and make certain it is structurally sounds.

The juncture of the floor and wall also needs special preparation before beginning a coved installation. Follow the instruction below to install the cove cap and the cove stick (cove fillet strip)

· Measure desired height for the cove caps at each corner and strike a chalk line.

· Attach aluminum or vinyl cove caps at this height using flathead nails with a hammer or brad pusher, or use contact cement.

· Always miter inside and outside corners in the cap. When mitering the outside corners, file the ends of the cap smooth. Use a specially designed miter tool with interchangeable die sets to make corners on the cove cap. This tool eliminates sharp edges at the outside corners.

· Cove sticks support the resilient flooring as it is flashed up the wall, eliminating the chance of puncturing the resilient flooring. Firmly secure plastic or wood cove sticks where the floor meets the wall with adhesive or nails.

· Use nonstaining nails and set the flush with the stick. The stick should have a minimum radius of 1 1/8” and be precisely mitered at all inside and outside corners.

· Provide a smooth transition in the door casings and other areas where the coving ends by cutting back to the cove stick.

· Tack the scribing felt to the wall with brad type nails before beginning to scribe it. Use a combination square, a small metal ruler, or a 1” piece of resilient to pattern scribe the felt.

· Fit the scribing tool up inside the cove cap and scribe the felt by sliding the tool along the cap as you mark the felt with a pencil.

· Scribe and cut the outside corners of the felt using a utility knife and the inside corners of the felt, using dividers.

· After scribing the entire work area, position the pattern squarely on the resilient sheet flooring and transcribe the pattern with pencil dividers. Be careful when cutting the material on the inside and outside corners.

· Dry fit the material. Inside corners should fit snug, but not be forced into position. Make sure to always position the shorter side first.

· Gently pull material away from the wall. Apply the appropriate adhesive to the floor, wall, cove cap, and cove stick.

· Allow the appropriate amount of open time. Fit the material back into place. Remember to always position the shorter side first.

· Roll the flooring with the appropriate size roller (use a hand roller on coved areas). Apply the appropriate seam sealer at all seams, following the recommended directions for the resilient floor being installed.

· The most demanding aspect of a coved installation is forming the outside corners. Fill outside corners with a “boot” type plug, rather than a V-type plug, on the least visible wall. The plugged corner fill piece should extent back at least several inches from the corner. The seam of the floor should be below the cove stick. Using an underscriber, scribe the back of the plug at the corner. This will mark the pattern of the corner on the plug.

· Cut along the scribed line at a 45 angle with a curved trim knife or a utility blade while holding the plug steady with a metal ruler and your other hand. When cutting, leave the face of the plug longer than the back.

· Check the fill piece for accurate fit. Make any minor adjustments to the plug as necessary to fill the space corrrectly. Remove the fitted fill piece and apply the appropriate adhesive. Reposition the fill piece and apply seam sealer.

NOTE: If planning to heat weld the seams, be aware that only Mannington Commercial Fine Fields, BioSpec MD, Mannington Assurance II, Magna, and LifeLines II products can be used. Remove the urethane coating before heat welding each inside corner by grooving or sanding. Preformed metal corner caps may also be used.

Commercial Vinyl Composition Tile: ColorPoint

General Instructions : Follow all General Installation Guidelines as described in the Installation Guide. Always store Mannington Commercial Vinyl Composition Tile (VCT) and Premium Tile (PT) in a protected, dry interior area. Do not double-stack pallets. Keep the job site, adhesives, and tile at a minimum temperature of 65F and maximum of 100F for at least 48 hours before installation. Maintain this minimum temperature during the installation and for 48 hours after the installation to assure proper bond of the adhesives.

Store VCT and PT on a dry, level surface. Do not stack VCT or PT cartons more than five cartons high. Be careful to stack cartons in straight tiers. Never double-stack pallets of VCT or PT cartons. Store pallets so they are protected from accidental damage from forklift trucks or other traffic. Protection of the carton corners is highly recommended.

If you intend to cover a concrete slab with resilient floor covering, always test the concrete slab for the presence of moisture.

The required quantitative tests are calcium chloride test or the in situ relative humidity test. The maximum acceptable moisture vapor emission specification is not to exceed 8 lbs per 1, 000 sq. ft per 24 hours or not exceed 85% RN for all Vinyl Composition Tile and Premium Tile products when installed with Mannington M-Guard V-11 Vinyl Composition Tile adhesive. This only applies to Mannington Commercial VCT and PT installations using M-Guard V-11 adhesive. If any other adhesive is specified or selected, follow the adhesive manufacturer’s warranty and recommendations regarding acceptable maximum moisture emission levels. The 5 lbs. moisture vapor emission rating is only applicable to Mannington Commercial VCT, PT, and Commercial felt-backed Resilient sheet products, and not any other Mannington Resilient sheet product. The maximum acceptable moisture vapor emission level for all Mannington Residential, homogeneous and heterogenous Resilient sheet products is 3 lbs. per 1, 000 square feet per 24 hours except when using M-Guard V-68 high moisture resistant adhesive for Commercial Vinyl Back products.

NOTE: Moisture testing can only indicated conditions at the time of the test and cannot predict any future changes in moisture levels. Neither Mannington nor the flooring contractor can be responsible if moisture levels change in the future.

Install Mannington VCT and PT only after the job site has been cleaned and cleared of other trade apparatus that may damage the finished tile installation. The lighting on the job site must be sufficient to permit inspection and preparation of the underfloor, layout, installation, cleanup, and final inspection of the tile. Always check the cartons to assure the pattern number is correct and that there is sufficient quantity of tile for the installation. Make certain the lot numbers are the same on all cartons. To minimize any minor shade variation on large installations, mix and install tiles from several different cartons. If the shade variation is extreme, do not install the tile.

NOTE: Please be aware that installing Vinyl Composition Tile (VCT) and Premium Tile (PT) over existing flooring may reduce its excellent indentation resistance.

Adhesive Recommendations & Application: M-Guard V-11 is a premium moisture-resistant pressure-sensitive adhesive developed specifically for installing Mannington Commercial Vinyl Composition Tile (VCT) and Premium Tile (PT) over approved substrates. Intended Use: M-Guard V-11 may be used on concrete or approved and appropriately constructed wood or wood composition subfloors/underlayments. M-Guard V-11 is suitable for use over new concrete substrates with in-situ moisture measurements of 85% RH as measured by ASTM F2170 or moisture vapor emission rate (MVER) of up to 8 lbs (3.6 kg) per ASTM F 1869, and a pH below 11 (M-Guard V-11 is not designed to be used over floors with moisture vapor emissions (MVE) from water of intrusion or hydrostatic pressure. It is designed only for slabs with high vapor emission from water of hydration). All concrete slabs on or below grade must have a functioning vapor barrier directly under the concrete slab.

Use of adhesives contrary to this recommendation is strictly the responsibility of the flooring contractor and/or the adhesive manufacturer.

Application:

· Make sure the subfloor is clean of dirt, paint, oils, wax, etc. The subfloor must be smooth and level before starting the installation.

· Maintain the adhesive, tile, and job site at a minimum temperature of minimum temperature of 65F and maximum of 100F for at least 48 hours during the installation, and for 48 hours after the installation.

· After you complete the tile layout, apply adhesive to one-half of the work area. Exercise caution to maintain the working lines. If necessary, re-strike the working lines over the adhesive after it dries clear.

· Apply M-Guard V-11 with a trowel notched 1/16” wide, 1/32” deep, and 1/32” apart. M-Guard V-11 can also be applied using a roller or a brush.

· Apply adhesive evenly, with no bare spots or heavy puddles. Avoid overlapping edges of adhesive.

· Before installing tile, allow M-Guard V-11 adhesive to develop tack and dry. This normally takes 45 to 50 minutes. Humidity and/or subfloor porosity, however, always dictate the proper open time.

· Set tiles firmly against adjoining tiles and press into adhesive. Do not slide tiles into place.

· You can remove fresh adhesive smears with a cloth dampened with water. Dried adhesive may be cleaned using mineral spirits and a clean cloth.

Tile Installation:

After the M-guard V-11 adhesive dries, begin laying tile at the intersection of the working lines. Place the first tile squarely against the working lines. Since the positioning of this tile determines the accuracy of the entire installation, it is critical to lay the starter tile exactly on the lines.

Once you have set the first tile firmly in place, begin laying tiles outward along both guide lines. Place tiles firmly against adjoining tiles and press into adhesive. Do not slide into place. Keep tiles on the guide line.

After you have positioned several tiles along the working lines, begin stair-stepping tiles into the field area. This will keep tiles square to each other throughout the installation. Lay tiles up to where border tiles must be cut to fit. Apply adhesive to the second half of the work area, let it dry clear, then continue laying tile.

Cutting & Fitting Border Tiles:

You may cut border tile to fit, using several techniques. The most common technique for square layouts is to place a full tile directly over the last full field tile. Using another full tile placed firmly against the wall and over the border tile, score the border tile. Be certain the graining of the border tile is properly alighted. Cut the border tile along the scored line and position factory edges of tiles together with the cut edge against the wall.

Use a template cut from stiff cardboard or hardboard to cut border tile in diagonal layouts. For Mannington Commercial 12” VCT and PT, cut the template to the diagonal dimension of the tile, approximately 17” square. Use accurate measurements to measure and cut the template. Use the template in place of the tile and proceed as outlined above.

You may direct scribe or pattern scribe the border tile for irregular walls, pipes, etc. For intricate cuts, we recommend you heat the tile from the back and cut with a sharp utility knife along the scribed marks.

Finishing & Maintenance:

Do not wash or scrub the floor for at least 4 or 5 days after installation, to allow the floor tiles to bond to the underlayment/subfloor. Keep heavy furniture and equipment off the floor for at least 48 hours to allow the adhesive to set. Sweep or vacuum thoroughly, and remove any residual adhesive with a clean, white cloth dampened with mineral spirits. Apply a minimum of two coats of a high-quality cross-linked acrylic floor polish to temporarily protect the floor until regular maintenance procedures can begin. Leave Mannington maintenance and warranty literature with the end-user. These are available from your Mannington Distributor.
