511 Porous Plus is a penetrating sealer designed for the protection of the most porous surfaces. 511 Porous Plus forms an invisible barrier that is resistant to moisture and stains while allowing vapor to escape. 511 Porous Plus is not a surface coating and will not alter the natural look. All surfaces are harder and less slippery. INDEPENDENT TESTS SHOW 511 POROUS PLUS OUT PERFORMS COMPETITIVE PRODUCTS. (Test results are available upon request).

Coverage: 500 - 2,000 square feet per gallon (72 - 180 square meters per 3.785 liters). 2,000 - 4,000 square feet per gallon (288 - 360 square meters per 3.785 liters) on polished surfaces.

How to Use:

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. 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.

After Grouting: 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. If grout clean up is not performed effectively, an additional cleaning may be necessary to remove remaining grout residue or haze.

For this procedure use Phosphoric Acid Cleaner , (GCFR) Grout & Concrete Film Remover (Hydrochloric Acid), Sulfamic Acid Crystals or Epoxy Grout Film Remover following the instructions carefully.

Residue Removal:

To remove accumulated 511 Porous Plus residue, use Miracle Residue Remover as directed.

Cure time

511 Porous Plus will be dry to the touch in 1 - 3 hours and may be used for normal foot traffic. For optimum results the area should be kept dry and free from staining materials for 24 - 72 hours.

511 Porous Plus is V.O.C. Compliant where applicable.
