BLOCK OUT MAX - SEALER 329
BLOCK OUT MAX 329 is a premium, water-based impregnating sealer engineered to provide deep, long-lasting protection for natural stone, pavers, tile, and grout. Once applied, Block Out creates a transparent, vapor-permeable barrier that repels both water and oils, helping surfaces stay cleaner and more resistant to stains. Block Out chemically bonds within the surface, internally sealing the substrate. This allows water vapor to breathe out of the stone, while inhibiting moisture and oils from penetrating the surface.
BLOCK OUT MAX penetrates immediately, deeply, and effectively, providing a long-lasting protective barrier. Block Out inhibits algae, mildew, and efflorescence while protecting from water damage and corrosion. Surfaces treated with Block Out will retain a natural appearance with no shine or gloss. For interior and exterior use.

SURFACE PREPARATION & APPLICATION:
Block Out Max can be applied using a roller, brush, flat mop, low pressure sprayer, or other suitable applicator. Ensure the surface is clean, dry, and free of dirt, grease, oil, or wax before application. Apply the sealer evenly and uniformly, wetting the entire surface. Allow to dry for at least 30 minutes, then apply a second coat. Any excess sealer not absorbed after 30 minutes can be spread across the surface and allowed to dry or wiped up with a dry mop or clean cloth. Product fully cures in 24–48 hours. When used prior to grouting, BLOCK-OUT acts as a grout release, helping simplify grout cleanup.
