Use of latex for impregnating porous substrates
First Claim
1. A method for reinforcing porous substrates, the method comprising the step of applying a latex to a porous substrate wherein the latex comprises at least one polymer dispersed in the form of particles with diameter between 50 and 200 nm, is stabilized with at least one surfactant, and has a solids content between 20 and 60%, characterized in that the latex further comprises between 10 and 50% by weight in relationship to the dispersed polymer of alkali-soluble polymer.
