Three Stain Types. Three Different Looks.

Choose the stain system that best matches the look, application style and level of color control you want for your interior floor.

Build Your Interior Floor Project

Calculate It. Choose It. Add It All to Cart.

Enter your floor size, choose your preparation, stain color, dilution, sealer and application tools, and we’ll build your estimated shopping list.

1

Enter Your Floor Size

Measure the length and width of the concrete area.

Project area 0 sq. ft.
2

Surface Preparation

Choose what your floor needs before staining.

CR-765 automatically adds CR-585 Neutralizer. CR-590 automatically adds CR-580 Degreaser.

3

Choose Your Stain + Color

Select the stain system first, then choose the exact color and dilution you want.

Diluting RAC can create a lighter appearance. Because RAC chemically reacts with the concrete, every floor will develop unique color and variation.

TSC may be diluted with acetone for a softer, more subtle and translucent appearance. Acetone is purchased locally.

RAC automatically adds CR-585 Surface Neutralizer. TSC requires acetone purchased locally.

4

Choose Your Interior Sealer

Select the protective sealer and finished sheen you want for your stained floor.

Choose CR-515 for an acrylic finish, CR-545 for a matte urethane finish, or CR-546 for a high-gloss urethane finish.

5

Choose Your Floor Finish

A renewable interior floor finish is included with every completed project.

Estimated at 1,000 sq. ft. per gallon per coat. Floor finish should be applied only after the sealer has fully cured according to its instructions.

6

Choose Stain Application Tools

Select the sprayer you want included for applying your stain.

The ReCharger is not recommended for RAC. If Recommended is selected, the calculator chooses VersaStain for WRC/RAC and ReCharger for TSC.

7

Choose Sealer Application Tools

Add the roller tools needed to apply your interior sealer.

CR-515 calls for a high-quality 3/8" nap lint-free roller cover. CR-545 and CR-546 may be applied with a shedless roller cover appropriate for the product instructions.
