LB-321

Product Description

CRACKBOND® LR-321 family products are two component, high modulus structural epoxy formulations designed to repair cracks in concrete. Due to their ultra-low viscosities, LR-321 and LR-321 LPL are perfect for gravity feed repair of fine to medium size cracks. LR-321 G, howev er, has a thixotropic gel-like consistency, and is ideal for medium blind-side crack repair, as it flows when under pressure and gels once injection stops. The usable temper ature range is between 50 °F and 100 °F (10 °C and 38 °C).

Ll-321 Crack Injection Epoxies

Surface preparation will be dependent upon the application of the product. Old concrete must be clean and profiled or textured.

New concrete should be a minimum of 28 days old. All dirt, oil, debris, wax, grease or dust must be removed. Prepare the sur face mechanically using a scarifier, sandblast, shotblast or other equipment that will give the surface profile needed for the ap plication. A roughened surface is imperative for good adhesion. Always be sure the bonding surfaces are prepared in advance before starting a new cartridge or mixing product. If at all possible, schedule dispensing to consume an entire cartridge at one time with no interruption of epoxy flow. For bulk, mix only enough product that can be used within the pot life, see Table 2.

Cartridge Preparation

Shake the cartridge vigorously for 60 seconds, then stand cartridge upright for at least 1 minute allowing any bubbles to rise to the top. NOTE: This step is not necessary for CRACKBOND LR-321G.

Insert cartridge into the dispenser. Make sure it is properly positioned with the shoulder of the cartridge flush with the fronUtop bracket of the dispenser. Point upward at about a 45° angle. Remove the plastic cap and plug from the top of the cartridge.

Continue to point the upward away from yourself and others while slowty applying pressure to dispenser moving any bubbles and product up through the nozzle until it reaches the tip. Dispense this first full stroke of material into disposable container. The cartridge is now purged and ready for flow control installation.

NOTE: The flow control supplied w ith the recommended nozzle should not be used for CRACKBOND

LR-321G.

CRACKBOND LR-321 and CRACKBOND LR-321 LPL: Find the flow control inside the threaded end of the mixing nozzle attached to a tape strip. Insert flow control into the two holes at the top of the cartridge where the product comes out. Make sure it is securely seated in place. Install mixing nozzle onto cartridge. Holding the dispenser straight up, slowly apply pressure to the dispenser moving any bubbles and product up through the nozzle until it reaches the tip. Tilting only slightly, dispense this first full stroke of material into a disposable container.

CRACKBOND LR-321G: Attach the mixing nozzle and dispense the first fu ll stroke of material into a disposable container. The cartridge is now ready for use.

NOTE: Schedule dispensing to consume an entire cartridge at one time with no interruption of flow to prevent material from hardening in mixing nozzle. If you have any problems in dispensing product, replace the nozzle; the product may have begun to cure in the nozzle which will affect the mix ratio. Never transfer a used nozzle to a new cartridge. Repeat the cartridge balancing steps listed above after replacing the nozzle.

Mix Instructions for Bulk Packaging Thoroughly stir each component separately before mixing them together. Mix only the amount of material that can be used before the working time expires. Proportion parts by volume into a clean pail at the exact and prop er mix ratio for that product (For CRACKBOND LR-321 family use 2 parts by volume of component "A" and 1 part by volume of component "B").

Mix thoroughly with a low speed drill (400 - 600 rpm) with a mix paddle attachment (i.e. a jiffy mixer). Carefully scrape the sides and the bottom of the container while mixing. Keep the paddle below the surface of the material to avoid entrapping air. Proper mixing will take at least 3 minutes.

Bonding Agent Applications

Bonding fresh concrete to hardened concrete or when used as a bonding agent for repairing concrete spalls: Using a brush, roller or airless sprayer, apply an even coat of the bulk mixed CRACKBOND LR-321 to the clean and prepared concrete surface. While the epoxy is still tacky, place fresh concrete over the top of the mixed epoxy.

Spall Repair Applications

To avoid a feathered edge, cut around the spall into sound concrete with a grinder or circular saw using a diamond or concrete abrasive blade. The edge cut should be equal to the maximum depth of the spall or to at least, a minimum depth of 3/4 in. (19 mm). Chip out all loose concrete within the entire spall to a minimum depth of 3/4 in. (19 mm). Follow surface preparation in structions above to clean the spall. Estimate the amount of bulk product needed and mix Part A and Part B, 2 to 1 by volume.

Mix part A and B thoroughly. Slowly add 3-4 parts by volume of kiln-dried sand or aggregate of choice and mix well, pour and trowel until smooth/level. Note: The low viscosity of LR-321 and LR-321 LPL will aid in wetting out aggregate to create a repair mortar. Maximum mortar thickness is 1.5 in. (38 mm) per lift.

LB-321 Crack Injection Epoxies

Gravity Feed Crack Repair for Horizontal Applications CRACKBOND LR-321 and CRACKBOND LR-321LPL are formulated for fine to medium cracks. 0.0025 in. to 0.125 in. (0.06 mm to 3.2 mm). For best results, cut a groove to open up the crack using an abrasive or diamond blade to a width of 1/8 in.

(3.2 mm) and minimum depth of 3/8 in. (9.5 mm). Use wire brush to abrade and then blow out the crack to remove all dust, dirt, grease, wax, oil or any other contaminants. Pour or inject CRACKBOND into the crack and its self-leveling ability will fill the entire area. Repeat application if necessary to completely fill crack. Follow the cartridge preparation set-up. For medium cracks, use CRACKBOND LR-321G.

Low Pressure Crack Injection for Vertical, Horizontal and Overhead Structural Repair Before repairs are attempted, examine the crack to determine the type of repair that is required. Cracks in concrete and wood members are classified as either dynamic (moving) or static (dormant). Static cracks may occur from a one-time overload event such as an earthquake or flood. For static cracks in a structure that is to be rehabilitated, structural crack injection is recom mended. By contrast, dynamic cracks are those which are caused by inadequate design, seasonal heaving, temperature swings or repeated over-loading. Dynamic cracks CANNOT effectively be repaired using crack injection. Dynamic cracks can be sealed using a flexible repair material such as CRACKBOND JF-311 (horizontal cracks).

Crack Injection Preparation Clean the surface surrounding the crack with a wire brush to achieve proper bond. Remove all dust, debris, oil and any other contaminants from the crack by blowing out with clean, oil-free compressed air. For best results crack must be dry at the time of injection. If water is seeping from crack, steps must be taken to stop the flow of water in order to achieve desired repair.

Capping Paste Cartridge Preparation

~[fji§ 1 MIRACLE BOND® 1310 is the perfect product to be used as a capping paste for crack injection. Its non-sag/fast-set properties are ideal for rapid installations (horizontal, vertical and overhead). Unscrew plastic cap from threaded end of cartridge and remove plug. Place cartridge into dispenser.

2 Balance the cartridge by dispensing a small amount of material into a disposable container until both materials flow evenly from the cartridge. Part A is white, Part B is dark gray.

3 Attach the mixing nozzle to the cartridge of MIRACLE BOND 1310 and dispense a small amount of material until uniform gray color without streaks is achieved.

4 Place and secure injection ports, or port bases, with the capping paste material. Port spacing should be approxi mately 6 -12 in. (152 - 305 mm) apart (typically the width of the concrete member). Do not allow the epoxy to block the passage between the port and the crack face.

5 Place additional MIRACLE BOND 1310 between the ports making sure the entire face of the crack is sealed off and ports are securely fastened to the concrete. If the crack is evident and accessible on the back side of the concrete member, seal with capping paste. Note: MIRACLE BOND 1450 may also be used as an alternative capping paste.

Port Information w

LB-321 Crack Injection Epoxies

Pump and Pneumatic Dispensing DO NOT EXCEED 40 psi (0.28 MPa) PRESSURE TO THE PNEUMATIC DISPENSING TOOL OR INJECTION PUMP. An air pressure regulator MUST be used with a pneumatic dispenser. Start at a low setting and gradually increase pressure as needed until desired epoxy flow is achieved. Use maximum 40 psi (0.28 MPa) air pressure. Excessive pressure may result in cartridge plunger leakage.

Begin the injection process from the lowest port on a vertical surface moving up the wall. On horizontal surfaces, begin at the widest part of the crack (as marked prior to capping) and move outward. Inject epoxy into port until you either get flow from adja cent port or until epoxy stops flowing.

Allow injection resin to cure for at least 24 hours. Ports and capping material can be removed with a chisel and/or grinder. Note:

Some cracks may take more time to inject, especially hair-line cracks. Cracks may be smaller in width (or larger) than they ap pear from the surface.

Dispensing and Injection Tips For basement walls where back side of concrete is not accessible, inject with slightly higher viscosity CRACKBOND LR-321G.

This is a unique thixotropic gel that will feed into small cracks and bridge the back side without runoff.

DO NOT dispense epoxy through gelled mixing nozzle. If epoxy gels in nozzle, replace nozzle before continuing .

Easy Flow Repair Epoxy

Surface preparation will be dependent upon the application for the product. Old concrete must be clean and profiled or textured. New concrete should be a minimum of 28 days old. Prepare the surface by rough-grinding, scarifying, bush hammering or by using other equipment that will give a roughened profile. A roughened surface is imperative for good adhesion. Always be sure the bonding surfaces are prepared in advance before starting a new cartridge or mixing product. If at all possible, schedule dispensing to consume an entire cartridge at one time with no interruption of epoxy flow.

Cartridge Preparation

~ Remove plastic cap and plug from threaded end of cartridge.

~ Place cartridge into standard caulking gun.

LI

CAUTION: Check the expiration date on the cartridge to ensure it is not expired. Do not use expired product! Before attaching the nozzle dispense enough material into a disposable container until both resin and hardener flow evenly.

D Attach mixing nozzle to cartridge and dispense a small amount of material into same waste container until a consistent color with no streaks is obtained .

Spall Repair Preparation

• WARNING: Use MIRACLE BOND 1310 Easy Flow for SMALL SPALL REPAIRS ONLY. A deeper or larger mass than recommended will generate excessive heat and may result in smoking, cracking and the material rising

• Always keep nozzle submerged in the adhesive while filling the spall to avoid entrapping air into the repair

• NOTE: For larger spalls use slower curing MIRACLE BOND 1450

• For MIRACLE BOND 1310, the spall should be ground to a maximum 1 in. (25 mm) depth and width no greater than 5 in.

(127 mm) for repairs placed at 77 °F (25 °C)- spall size may need to be reduced at elevated temperatures

• Avoid a feathered edge by cutting around the spall into sound concrete with a grinder or circular saw using a diamond or concrete abrasive blade so the entire depth of the spall is consistent

• For patching concrete or wood surfaces, fill the void with MIRACLE BOND 1310 to just above the surface level and trowel ftush

Capping Ports for Structural Crack Repair

• Place and secure injection ports, or port bases, with the MIRACLE BOND capping paste taking care not to leave any pinholes, noting that the port spacing should be approximately 6 - 12 in. (152 - 305 mm) apart

• N 0 TE : Do not allow the epoxy to block the passage between the port and the crack face

• Place additional MIRACLE BOND between the ports making sure the entire crack is sealed off anywhere it is visible and accessible and make sure the ports are securely fastened to the concrete so they will not leak when injected under pressure

• Allow the MIRACLE BOND to cure before injecting the crack with an ATC crack injection adhesive such as CRACKBOND

LR-321

• NOTE: Low temperatures will increase cure time, higher temperatures will decrease cure time

VOCOMP@-30

- ... <:..\:.'\) E:;~-'" ·. t c... ,\ L. 5 0 ?-r ., Water-Base Acrylic Concrete Curing and Sealing Compound

DESCRIPTION

VOCOMP-30 is a ready-to-use, 30% solids Concrete Curing and Sealing Compound formulated of special acrylic polymers in a true water-base carrier.

VOCOMP-30 provides improved resistance to rain, sun, freezing temperatures, most acids and industrial chemicals, petroleum, deicing salts, cleaning agents (except aromatic solvents), diluted caustics and other pollutants.

Color-wise, VOCOMP-30 appears "milky-white" in the container and when first applied, leaves a "bluish" cast on the concrete for easy visual coverage. VOCOMP-30 dries clear to provide a transparent sheen finish. This sheen can be controlled by the number of coats applied. VOCOMP-30 meets maximum VOC content limits of700 g/L for Concrete Curing and Sealing Compounds as required by the U.S. EPA Architectural Coatings Rule.

USES

VOCOMP-30 may be used wherever a thicker film, with a medium to high sheen, is desired to bring out the natural beauty of concrete without discoloring, checking or peeling. When properly applied, VOCOMP-30 provides an impermeable seal for superior moisture protection. Jt may be applied to simultaneously cure, seal and dustproof new and old, interior and exterior, horizontal and vertical concrete surfaces. VOCOMP-30 is ideal for curing, sealing and dustproofing driveways, sidewalks, patios, swimming pool areas and commercial and industrial floors. Horizontal surfaces protected with VOCOMP- 30 offer excellent wearing qualities for foot and vehicular traffic. If, after prolonged usage, traffic patterns appear, the surface can be washed clean and recoated to restore the original beauty. Good concrete and good concreting practices should be used as VOCOMP-30 is not a cure-all for improperly mixed or placed concrete.

APPLICATION

S11rface Preparation ... Existing (old) Concrete:

Surface preparation is extremely important. Concrete must always be clean and dry, with all stains, oil, grease, dust and dirt removed prior to application. If not, they will be amplified by the transparent sheen finish. CAUTION: If a liquid compound other than VOCOMP-20, VOCOMP-25 or VOCOMP-30 has been used, do not apply VOCOMP-30 until all traces of the compound have been con1pletcly removed and the surface is clean and dry. Ne1v Concrete: Apply VOCO!vlP-30 when the surfhce water has disappeared and the concrete surface will not be marred by walking workmen.

Mixing ... For optin1um performance, gentle mixing or agitation is recommended. CAUTION: TO AVOID

FOAMING, DO NOT MIX EXCESSIVELY.

Application Method ... A typical commercial sprayer provides an easy, economical 1ucthod of application.

VOCOMP-30 should be sprayed on with an 8001 tip that produces a flow of 1/10 of one gal!on per minute.

Spray on in a fine, fog pattern without spurts and dribbles lo form a thin, continuous film. AVOID PUDDLING in low areas .. .ifpuddles occur, brush or roll them out. For added protection and a greater sheen on new or existing (old) concrete, we rcco1nmend (2) coats ofVOCOMP-30 be applied at right angles. Additional coats of VOCOMP-30 may be applied after the first coat has thoroughly dried.

Drying Time ... VOCOMP-30 dries quickly. Drying times 1nay be extended depending on application rate, temperature, humidity and project conditions.

Restrict foot traffic for al least four honrs ... 12 hours is preferable.

LIMITED WARRANTY

Clean up ... While VOCOMP-30 is still wet, equipment may be cleaned with soap and \Vater.

Once dried, the material may be removed \vith a solvent such as Xylene or Toluene.

Application Tool

PRECAUTIONS

KEEP FROM FREEZING. Do not dilute. Do not apply VOCOMP-30 when air, material and surface temperatures arc expected to fall below 40°F (4°C) within 4 hours of completed application. DO NOT

MIX "WATER-BASE" COMPOUNDS WITH ANY

COMPOUND CONTAINING SOLVENT.

VOCOMP-30 1nay be applied to colored concrete, but 1nottling may occur. Do not use on non-porous surfaces or surfaces which arc not uniform in porosity, i.e., brick, stone, masonry, etc. Concrete floors properly cured \Vith VOCOMP-30 meet section 8.9 "Adhesion of Tile Cements" of ASThl C 1315.
