1) PRODUCT STORAGE: Store product at normal room temperature before using. Continuous storage should be between 60 and 90 degrees F.

2) SURFACE PREPARATION: The most suitable surface preparation would be a 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 disbonding. For applications directly over concrete, Testing should be performed to confirm a moisture vapor emission rate below 3 lb/24hr/1000 ft2 per ASTM F1869.

3) PRODUCT MIXING: This product has a mix ratio of one to one by volume. 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.

4) PRIMING: A suitable primer should be used before applying this product. See the front side of this technical data for primer information. However, whether a primer is used or not, it is advisable to apply a test patch prior to using this product to determine if the adhesion characteristics are suitable for the service environment.

5) PRODUCT APPLICATION: The mixed material can be applied by brush, serrated squeegee, or roller. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. The product is intended to be used as a topcoat to seal in the broadcasted paint chip or broadcasted quartz base for the final coat. Use an air release roller tool when needed. Improper mixing may result in product failure. It should be pointed out that relative humidity can have a dramatic influence on the curing characteristics. The product will dry quicker and have less working time when the relative humidity is higher while a lower relative humidity will lengthen the dry time and working time. If necessary, the addition of a pigment pack will also result in less working time. Mix only an amount that can be applied in the time allotted. Be sure that any tie-ins to previously applied material is also within the recommended time allotted for use as the previously applied material may begin to tack off in a short period of time.

6) RECOAT OR TOPCOATING: This material can be applied in multiple layers to increase build but is intended to be used as the final topcoat to seal in the aggregate filled base system. 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 top coating can commence. Non-slip aggregate is available and recommended when coating pedestrian surfaces.

7) CLEANUP: Use xylol

8) FLOOR CLEANING: Caution! Some cleaners may affect the color of the floor 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.

9) 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. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

The Strength of Diamond. The Confidence of a Lifetime.

Dymond Coatings are engineered with the same qualities as their namesake — tough, long-lasting, and built to bond for life. That’s why we back every eligible Dymond kit with our Lifetime Promise: if your floor fails due to a verified product defect, we’ll replace the material or issue a credit toward your next job. This warranty applies to complete Dymond systems (primer, base coat, and topcoat) when installed on indoor concrete surfaces and applied according to Dymond’s preparation and application guidelines. Covered issues include delamination caused by faulty resin blends, curing failure due to batch defects, and contamination introduced during manufacturing or packaging. To qualify, the product must be within shelf life, used under proper storage conditions, and installed using only Dymond components.

This warranty does not extend to issues arising from improper surface preparation, substrate contamination, excessive moisture vapor, impact or abuse, substrate movement, or UV discoloration of white/light epoxies. Installations over wood, tile, or outdoor surfaces are excluded unless specifically approved. Cosmetic issues such as texture variation, microbubbling, or minor tint shift are not covered. Warranty coverage is limited to the original purchaser and is non-transferable. Claims must be submitted with photographic evidence of each install stage and full batch documentation. Dymond reserves the right to determine whether the cause of failure falls within warranty scope.

This Promise applies to most DIY and light commercial indoor projects. Larger commercial and industrial installations may be eligible for custom coverage — contact us for terms.
