Patent ID: 7527703

Claim:
A method for sealing an inward-facing surface of a concrete pool, said inward-facing surface having a plurality of pores opening and extending into said surface, comprising: a. preparing said surface; b. providing a sealer, wherein said sealer includes i. between about 5% and about 50% silicone oil by weight; ii. between about 2% and about 15% silicone fluid by weight; iii. between about 1% and about 5% amorphous silica by weight; iv. between about 50% and about 90% mineral spirits by weight with said mineral spirits being in a sufficient concentration to reduce the viscosity of said sealer such that it wicks into said surface for a substantial distance without forming a film on said surface thereby filling said plurality of pores within said concrete for a substantial distance; and c. applying a sufficient quantity of said sealer to said surface to fill substantially all of said plurality of pores in said surface so that said sealer penetrates and seals said surface.
