Marble Sealer Performance Test*

Marble is a softer, more porous natural stone and benefits from proper sealing to help resist staining. BAGM applies a professional 15-year Stain-Proof sealer at installation.

To evaluate sealer performance, place a few drops of water on the surface for 10–15 minutes. If the area darkens, the stone may need to be resealed. If the water beads and does not absorb, the sealer remains effective.

Please note: Sealing helps reduce staining but does not prevent etching or scratching, which are natural characteristics of marble.

Proper cleaning and maintenance will help maximize the life of your sealed surface.

*Marble needs a slight distinction because sealing helps with staining — not etching.
