Question 4: _The specifications reference to the Material Finish List on Drawing A101 as Dur-A-

Flex Basis of design for the floor coating system. The question was brought up by Dur-A-Flex if further detail of the coating system can be provided? It appears that basis of design is not a floor system in the Dura-Flex family of floor systems. The closest system they have to meeting the basis of design is their Hybrid-Flex ES system. Please provide further clarity.

DUR-A-GLAZE #5

DESCRIPTION

DUR-A-GLAZE #5 is a clear, two-component aliphatic polyaspartic ester high performance polymeric system. It is designed to provide protection against many solvents, acids and chemicals. DUR-A-GLAZE #5 is resistant to deterioration by ultra-violet rays emitted by sunlight, high intensity lighting systems, fluorescent lighting, etc. It is applied as the final topcoat. When the resin and the hardener are combined and mixed thoroughly, an extremely dense chemical cross-linking action occurs. This special cross-linking of the two components produces a coating that provides abrasion resistance equal to or better than ambient temperature cured epoxy or two- component aliphatic urethane systems.

BENEFITS

Very Fast Curing

Very Low Odor

Non-Ambering

Good Chemical Resistance

Good Abrasion Resistance

Good Stain Resistance

Easy Maintenance

LIMITATIONS

This product is best suited for application in temperatures between 55°F and 85°F. Substrate must be clean, sound, and dry. Do not apply at temperatures below 55F or above 85F.

When recoating Dur-A-Glaze #5 after the re-coat window has passed (24 hours or longer), aggressively sand the floor using a floor machine with 60-100 grit paper to remove gloss then solvent wipe with Xylene. Apply Dur-A-Glaze #5 as stated on the Application Instructions. Dur-A-

Glaze Tie-Coat is not needed or recommended as a primer.

TYPICAL USES

Protective topcoat for DUR-A-QUARTZ, DUR-

A-CHIP, POLY-CRETE MDQ and MDC systems.

Topcoat for Washrooms, Kennels, Laboratories and Hospitals

COLORS

DUR-A-GLAZE #5 is available clear.

PACKAGING

DUR-A-GLAZE #5 is available in 3-quart pre-measured kits.

SURFACE PREPARATION

SHOP FLOOR

SHOP FLOOR Epoxy Flooring is a combination of pigmented DUR-A-GLAZE SHOP FLOOR, a 100% solids epoxy and Flintshot, a natural quartz sand. The epoxy and the quartz aggregate are fused together during application into a monolithic surface that is extremely durable, thickness ranges from 1/16"- 1/4". SHOP

FLOOR Epoxy Flooring is similar in application technique, durability and chemical resistance to the time tested DUR-A-QUARTZ Epoxy Flooring. It is available in three different textures; standard non-skid, orange peel and smooth.

Excellent Clarity

Low Odor

Meets USDA, FDA, OSHA standards

Superior Adhesion

Superior Chemical Resistance

Easy Maintenance

SHOP FLOOR is available in 15 standard colors. The color White is only available for use with the DUR-A-

GARD S/L 100 mil system. Please refer to the Standard

Color Chart @ Standard Color Chart. Custom colors are available upon request.

TYPICAL USES

SHOP FLOOR Epoxy Flooring is designed for use wherever USDA, OSHA, FDA and EPA standards must be met. It can be applied on most sound substrates including concrete, quarry tile, brick pavers, steel decks, plywood floors, etc. It is ideally suited for heavy-duty industrial applications, particularly in areas requiring durability, easy maintenance, a high degree of sanitation, and high acid and chemical resistance. SHOP FLOOR

COAT. Please refer to the master “Surface Preparation

Guide” for more information.

APPLICATION METHOD/SPREAD RATE

SHOP FLOOR is applied with a roller, squeegee or trowel. A typical yield at 1/8” thickness is approximately

ARMOR TOP™

ARMOR TOP is a two, three or four component aliphatic urethane protective coating. It was formulated for high traffic areas to protect against chemicals and wear. It is available in either a clear or pigmented, gloss or satin finish, and with or without high wear resistant aluminum oxide (grit).

VOC- 0 g/L clear (pigmented - see Tech Info)

Low Odor

Light Stable

Excellent Abrasion Resistance, 3 to 4 times better than other urethanes; 9 times better than epoxies

Excellent Chemical Resistance

TYPICAL USES

It is designed to be used as a final topcoat over DUR-A-FLEX epoxy systems.

ARMOR-TOP is available clear or in 15 standard colors. Please refer to the Standard Color Chart on our website. Custom colors are available upon request.

ARMOR TOP should not be applied more than 3 mils wet.

During application, DO NOT use 9 inch rollers and make sure that the floor temperature and materials are between 60˚F and

80˚F. Do not coat floor if moisture is present. Do not coat floor unless floor temp is more than 5 degrees over the dew point. Do not apply if RH >80%. Do not apply ARMOR TOP over epoxies cured with FAST hardener. ARMOR TOP should be pigmented when applied over pigmented systems.

Dry Time is slower when Relative Humidity is less than 30%.

For vertical applications, two coats are required – the second coat must be applied within 24 hours of the first. Do not apply

Armor Top clear with Armor Top grit on a smooth floor (like

Dur-A-Gard, ReFLEXions, etc.) as roller lines may be visible.

For applications where humidity is less than 30% use

ARMOR TOP LH. This is available in gloss finish only.

Tack-free time is approximately 6 hours. All other data remains the same as standard ARMOR TOP gloss.
