Frequently Asked Questions

What type of sand should be mixed with FlexKrete?

Always use kiln-dried blasting or industrial sand. For troweling, a good mesh size is 20-50 mesh, or medium grade sand. For matching very smooth surfaces, a finer mesh may be used. Any size or type aggregate may be mixed with FlexKrete, as long as it contains no moisture. Color quartz, aluminium oxide, flint, Black Beauty, small gravel, etc. may all be used with FlexKrete, depending on your surface needs.

Can FlexKrete be stained or painted?

Yes, it can be stained or painted, usually within an hour of application. Water-based or 100% solids materials should be used.

What are the temperature application restrictions?

There are no temperature restrictions for applying FlexKrete. It has been applied temperatures well over 100° F, as well as in frigid areas of -34° F. It's the perfect solution for freezer rooms or any cold weather repairs.

What is the coverage of FlexKrete?

The coverage depends on the depth of the repair and how it is used. However, FlexKrete is 100% solids by volume, so the spread rate is as much as can be obtained from any product.

How much does FlexKrete cost?

When mixed with 3 parts sand, a 5 gal pail will yield about 20 gallons of mixed product. That makes the price per gallon less than $20. Different applications will vary in cost, depending on the application, aggregate type and loading. We also have an on-line calculator to help you figure the job.
