SCS-004 is a heavy duty, high solids, nanoparticulate cross-linked with a silane- siloxane micro-emulsion. This water based sealer can be used on all concrete, block as well as other porous concrete, masonry and stucco surfaces. It is a special blend of nanoparticulate and a silane-siloxane micro-emulsion that helps fill and penetrate pores and capillaries in porous substrates without producing a heavily sealed or coated appearance. SCS-004 produces an excellent water proof treatment in one or two coats, depending on substrate porosity.
