COMPOSITION AND METHOD FOR TREATING CEMENT, CONCRETE, MORTAR OR FLOOR SCREED OR THE LIKE MATERIALS AND USE THEREOF

摘要

A method for treating surfaces of cement, concrete, mortar or floor screed or stone, marble or granite by applying at least one layer of a composition comprising of 2-20% by weight of particles of plasticized polyvinyl butyral (PVB) dispersed in water in an amount of 100 g/m2-600 g/m2. This ensures that the surfaces exhibit improved resistance to wear and reduced creation of dust during wear, i.e., a dust binding effect is achieved and protects the surfaces from being stained. The application of the aqueous PVB dispersion provides improved adhesion of conventional top coatings, such as epoxy or polyurethane (PU) based resins and results in a brighter surface on the treated surfaces. A composition and uses are also disclosed.

主权项

1. A dust binder and/or primer composition for cement, concrete, mortar, floor screed, stone, marble or granite comprising 6-18% by weight of particles of polyvinyl butyral (PVB) dispersed in water, wherein the PVB contains 15-30% of plasticizer.
