When to Use Impregnator Sealer?

Before Grouting: Apply 511 Impregnator to all surfaces prior to grouting. This allows for quick and easy cleanup after grouting. (Grout can stain many surfaces if this procedure is not used prior to the grouting process.)

What is the difference between sealer and impregnator?

Impregnator will keep the acid out of the stone but not off the top surface. Sealers on the other hand will provide protection on the surface and resist better stains but they do change the appearance (create shine and darker tone of color) and they will require frequent stripping and reapplication.

What is 511 Impregnator sealer used for?

511 Impregnator is the original penetrating sealer designed for the protection of all medium to dense porous surfaces. 511 Impregnator forms an invisible barrier that is resistant to moisture and stains while allowing vapor to escape.
