511 Porous Plus is a penetrating sealer designed for the protection of the most porous surfaces. It forms an invisible barrier that is resistant to moisture and stains while allowing vapor to escape. It also is weather resistant, U.V. transparent and is ok for food areas. Use it for your interior & exterior projects. 511 Porous Plus is not a surface coating and will not alter the natural look. Use on sanded grout, limestone, terra cotta, cement, brick, slate, saltillo tile, concrete tile, flagstone, polished marble & granite, pre-cast concrete, cantera/adoquin, flamed & honed granite, honed/textured marble and sandstone.

Application:

Apply 511 Porous Plus to all surfaces prior to grouting. This step will allow quick and easy cleanup after grouting. Grout can stain many surfaces if this procedure is not used prior to the grouting process. Apply 511 Porous Plus using a Mira Brush or a clean towel. Apply enough to wet the surface. (See coverage charts) Be careful not to saturate the open grout joints. Allow 511 Porous Plus to stand for approximately 3 - 5 minutes for maximum penetration. Any excess sealer remaining at this time should be removed by wiping the surface with a clean dry towel. On very porous surfaces apply another application after the previous application has dried 2-3 hours. Any excess sealer that has dried on the surface creating a residue/film, may be removed by applying Residue Remover. Apply Residue Remover undiluted to the affected area with a clean dry towel. Let it sit for 1 - 2 minutes before buffing the area with a second clean dry towel. Allow 511 Porous Plus to cure for 12-24 hours before continuing with the grouting procedure per manufacturers specification.

 

Once grouted, make sure that all grout residue is removed from the surface with a clean sponge and water. Allow grout to dry at least 24 - 72 hours.
