BEDROCK BINDER
DESCRIPTION:
Bedrock Binder is a two component 100% solids epoxy that can be used either as a coating or filled with paint chips, marble chips and colored sand mixtures to provide an infinite array of color schemes or patterns.
RECOMMENDED FOR:
Warehouses, kitchens, restrooms, and other areas where either a high build clear product is needed or where a decorative filled floor is desired.
PRIMER:
Self priming under most conditions.
APPLICATION TEMPERATURE:
55-90 degrees F
LIMITATIONS:
-Color stability or gloss may be affected by environmental conditions such as high humidity, chemical exposure, UV exposure or exposure to lighting such as sodium vapor lights.
-Colors may vary from batch to batch. Therefore, use only product from the same batch for an entire job.
-This product is not UV color stable. Clear aliphatic urethane topcoats reduce (UV light) color changes.
-Substrate temperature must be 5 degrees F above dew point.
-For best results, apply with a 1/4" nap roller.
-All new concrete must be cured for at least 30 days prior to application.
-Physical properties are typical values and not specifications.

MIXING AND APPLICATION INSTRUCTIONS:
1) PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degrees F. Low temperature fluctuations may cause crystallization.
2) SURFACE PREPARATION:The most suitable surface preparation would be a fine brush blast (shot blast) to remove all laitance and provide a suitable profile. All dirt, foreign contaminants, oil and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete is dry; 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 is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbanding.
3) PRODUCT MIXING: This product has a mix ratio of 2 parts A to 1 part B by volume. Mix well 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.
4) PRODUCT 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. This product can be used with various colored sand in a broadcast system or other suitable aggregate can be used in conjunction with this product to achieve a variety of color and application patterns. When using as a broadcast binder, always evaluate performance parameters with a test area which is dependent on aggregate size and thickness, prior to application. Contact your representative for details as necessary.
5) RECOAT OR 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.
6) CLEAN UP: Use xylol.
7) FLOOR CLEANING: CAUTION! Some cleaners may affect the color. Test each cleaner in a small area. If no ill effects are noted, you can continue to clean with the product and process tested.
8) RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured. It is best to let the floor remain dry for the full cure cycle.
