How do you know when you have applied enough?

Because every floor/casting slab is different, it is impossible to state specifically how many coats of Silcoseal Select are required to ensure clean panel separation. Several factors that affect the number of bondbreaker coats required include concrete mix design, finish, weather conditions, size of spray nozzle used, product application rate, and more.

Accordingly, Nox-Crete does not recommend a specific number of coats. Instead, we recommend a visual test to verify adequate coverage of Silcoseal Select. Successive coats of the product should be applied until all treated areas of the casting/floor slab remain uniformly dark in appearance for a minimum of four hours following the previous coat. The development of lighter colored areas on the floor/casting slab within the four hour time window indicates a porous condition requiring an additional coat(s) of bondbreaker. When sufficient bondbreaker has been applied, the floor/casting slab will be uniformly dark in appearance with a slightly sticky, wax-like feel (although Silcoseal Select does not contain any wax) to the touch.
