DECORATIVE QUARTZ BROADCAST SYSTEM APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Before use, store the product in an area to bring the material to normal room temperature. Continuous storage should be between 60°F and 90°F. Keep from freezing.

SURFACE PREPARATION: Surface preparation will vary according to the type of complete system to be applied. For a complete system build higher than 10 mils dry, we recommend a fine brush blast (shot blast). All dirt, oil, dust, foreign contaminants, and laitance must be removed to assure a trouble-free bond to the substrate. A test should be made to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause disbanding. However, the primer can be applied to a damp floor as long as there are no standing puddles.

PRIMER MIXING: This product comes pre-packaged by weight. Kits should be mixed in their entirety. If partial kits are to be used, refer to the front of this technical data for proper weight mix ratios. After the two parts are combined, mixes well with slow-speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak-free. This product is an emulsion product and should be mixed well before using.

PRIMER APPLICATION: The mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing process. Apply material with relative humidity within the parameters shown on the technical data. When the end of the pot life has been reached, you will find that the material becomes hard to apply and will actually tend to roll back up onto the roller. Do not try to continue application when the coating has reached this step. Applications made at different times with differing environmental conditions may show slight variations in gloss.

TOP-COATING THE PRIMER: When you topcoat the primer, you must first be sure that all of the solvents and water have evaporated from the coating during the curing process. The information on the front side of the individual data sheet is a reliable guideline to follow. However, it is best to test the coating before re-coating or top-coating. This can be done by pressing on the coating with your thumb to verify that no fingerprint impression is left. If no impression is created, then the re-coat or topcoat can be started. Always remember that colder temperatures will require more cure time for the product before top-coating can commence. Before top-coating, check the coating to ensure no epoxy blushes were developed (a whitish, greasy film or de-glossing). If a blush is present, it must be removed prior to top-coating or re-coating. A standard-type detergent cleaner can be used to remove any blush.

PRIMER CLEANUP: USE PM SOLVENT

BODY COAT MIXING: This product has a mix ratio of 9.0# part A to 4.15# part B. 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 unless suitable weighing equipment is available. 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. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the primed substrate. Improper mixing may result in product failure.

BODY COAT & BROADCAST APPLICATION: The mixed material can be applied by brush or roller. However, the material can also be applied by a suitable serrated squeegee and then back rolled as long as the appropriate thickness recommendations are maintained. 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. While the applied material is still wet, broadcast the appropriate colored sand by hand in an upward motion until the sand is applied to excess. Do not throw the sand downward, as this might cause uneven ridges to form. After the product has cured, remove excess and loose colored quartz by a broom or with a vacuum.

BODY COAT CLEANUP: USE XYLOL

2ND BODY COAT & BROADCAST APPLICATION:
Repeat the body coat and broadcast application and allow it to cure before topping with the grout coat.

GROUT COAT MIXING: This product has a mix ratio of 9.0# part A to 4.15# part B. Standard packages are in pre-measured kits and should be mixed as supplied. We recommend that the kits not be broken down unless suitable weighing equipment is available. 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. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the double broadcast application. Improper mixing may result in product failure.

GROUT COAT APPLICATION: The grout coat application will determine the texture of the overall system applied. For a more textured system, apply fewer liquids. For a smoother system application, apply a heavier build of the grout coat liquids. The mixed material can be applied by brush or roller. However, the material can also be applied by a suitable serrated or flat squeegee and then back rolled as long as the appropriate thickness is accomplished. 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.

OPTIONAL WEAR COAT:

After the grout coat application has cured, an optional urethane topcoat can be applied. This product has a two-to-one mix ratio by volume (two gallons of part A with one gallon part B — volumes approximate). 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. Avoid whipping air into the coating. Improper mixing may result in product failure. After mixing, the mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing process. It is best to maintain a wet edge to avoid roller marks. Too thick of an application may result in product failure. Exposure to certain types of lights such as sodium lights may cause the product to discolor.

FLOOR CLEANING: Test each cleaner in a small area. If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle.
