Can I use a Silcoseal bondbreaker to cure my casting/floor slab?

Yes. In fact, it is recommended that the floor/casting lab of all tilt-up projects be cured with Silcoseal cure and bondbreaker. The cure coat is the most important coat and will provide the foundation for the subsequent bondbreaker coats.

Both Silcoseal Select and Silcoseal 2000F meet the modified moisture retention requirements of ASTM C309.
