Westcoat TC-4 Fine Texture Cement
TC-4 is primarily used in conjunction with WP-81 and WP-82 Cement Modifiers and used in several Westcoat Systems. It is designed to be used in interior applications when a smooth surface is desired.
As a Primer
Mix 2 parts A with 1 part B (by volume) of EC-11 Water-Based Epoxy for 3-5 minutes. Apply at a rate of 250-500 square feet per gallon by spraying or rolling to ensure even coverage. TC-4 may be applied as soon as the EC-11 is tacky and not wet (approximately 1 to 4 hours at 70F degrees), but no later than 6 hours. If you are unable to coat over the primer within 6 hours, broadcast #30 or #60 silica sand into the wet primer (See complete EC-11 Product Specification Sheet).
Must add WP-81 or WP-82 and water. See specific System Specification Sheet for mixing instructions.
One 50 pound bag will cover 150 square feet to 350 square feet. Coverage will vary depending on use.
TC-4 may be troweled, squeegeed or broomed. See specific System Specification Sheet for detailed application information.See More
