Approximately, how many square feet will this cover?

Coverage rates vary depending on the surface porosity and texture. For porous, textured surfaces about 175 square feet per gallon. For semi-porous surfaces, about 550 square feet per gallon. For dense, smooth surfaces 1,150 square feet per gallon. Those are estimates. Testing an area would determine the actual coverage rate for your surface. Your PROSOCO Team.

Have an old building that plaster came off of brick. Very old porous brick. Would this stop the bricks from decaying more?

This product is only for masonry that is dusting, not decaying or spalling. Thank you very much. Your PROSOCO Team.

Is this product recommended for natural slate floors?

Interior Masonry Dustproofer can only be used on vertical surfaces. It is not for use on horizontal surfaces. Your PROSOCO Team .

Is there any warranty on the finish?

We do not offer a warranty on this product.
