Confused by Sealers? Take a look here: Sealer Buying Guide

Miracle Sealants 511 Porous Plus Sealer is a penetrating sealer designed for the protection of the most porous surfaces. The sealer forms an invisible barrier that is resistant to moisture and stains while allowing vapor to escape. Miracle Sealants 511 Porous Plus Sealer is not a surface coating and will not alter the natural look. All surfaces are harder and less slippery.

Apply Miracle Sealants 511 Porous Plus Sealer 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 the sealer 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 Miracle Sealants 511 Porous Plus Sealer 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 Miracle Sealants 511 Porous Plus Sealer 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.


It covers approximately 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.

Sealant with Competition April 19, 2013
Reviewer: Philip Hull from Oakland, CA United States  
This is the best sealant there is.  You can't do better for natural stone.  Water now beads on my natural stone floors like mercury would do. I't's expensive but you get what you pay for.  Cheaper sealants coat the surface with a film which ends up after a few months looking like peelng sunburned skin- pretty disgusting.  Extremely easy application (once you've cleaned the stone, which is the hard part!).  This sealant is not a surface coat but penetrates the outer layer of pores in natural stone and also in grouting and prevents water/stains from entering those pores but it allows the stone to still breathe.  Think of it like Gortex fabric but for stone (-:
