The M1000 integral waterproofing additive offers moisture protection for grout, mortar and stucco. Adding a small amount of M1000 upfront eliminates additional labor, equipment, and re-application. It also provides stain resistance, efflorescence control, freeze/thaw protection, and enhanced durability. The environmentally friendly product line replaces conventional external waterproofing membranes, which often emit volatile organic compounds and are composed of nonrenewable materials. Available in both liquid and dry formulations. Hycrete Inc. 201-386-8110.
