Countertop 745

Surface Prep

1. The concrete substrate to be coated must be clean, dry, and completely free of loose particles, grease, oil, or any substance that would interfere with proper bond.

2. Surface and air temperatures must be at least 55°F during application. Surface and air temperatures should not exceed 90°F. Keep material from freezing.

3. The surface-zone moisture content of the concrete should not exceed 4% wt.

4. Mechanical scarification with a 80-100 grit pad is recommended until a suitable profile is achieved.

Application Instructions

Mixing: Standard packages are in pre-measured kits and should be mixed as supplied in the kit. We highly recommend that the kits not be broken down. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. Improper mixing may result in product failure.

Application: - The mixed material can be applied by brush or roller. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. If concrete conditions or over aggressive mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating.

Recoating/Topcoating: If you opt to recoat or topcoat this product, you must first be sure that the coating has tacked off before recoating. Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence. Before recoating or topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film or deglossing). If a blush is present, it must be removed prior to topcoating or recoating. Many epoxy coatings and urethanes are compatible for use as a topcoat for this product as well as multiple coats of this product.

Coverage: 50 square feet per kit. Variations in texture and porosity of substrate will affect the coverage and performance of the product.

Clean Up

Clean equipment, tools and surfaces with xylol. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

Precautions/Safety

Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.

Best Performance

• Proper application is the responsibility of the user.

• Make sure the most current versions of technical data sheets and safety data sheets are being used.

• Keep out of reach of children and pets.

• Store in a cool, dry place away from direct sunlight. Avoid opened containers, as moisture will cure the material.

Application Notes:

• Restrict use of non-harsh chemicals until the coating is fully cured.

• Some cleaners may affect the color of the countertop installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

• Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure.

• For best results use a high quality nap roller.

• Substrate temperature must be 5°F above dew point.

• Relative humidity must be below 75°F.

• All new concrete must be cured for at least 28 days.

• Improper mixing or too thick of an application may result in product failure.

• Do not expose this product to water until fully cured.

• Too thick of an application may result in surface imperfections or bubble generation.
