Seal It Green Xtreme Heavy Duty Grout Sealer - Odorless, Stain Block

In this review the Seal It Green Xtreme Heavy Duty Professional Grout Sealer is presented for homeowners and pros who need long lasting, low-odor grout protection. The bottom line: it is best for anyone who wants a truly odorless, water-based sealer that blocks stains without changing tile appearance. The reviewer found the spray bottle application simple, coverage impressive for the container size, and the Stain Block Technology effective at preventing common household stains from penetrating grout.

Key Features

• Breathe Easy Stain Block Technology: Prevents black shower stains and food or dirt marks from penetrating grout so surfaces stay cleaner longer.
• Non-toxic, Zero VOC formula: Water based and made with plant based surfactants so there are no harsh fumes during indoor application.
• Spray bottle convenience: Allows application without kneeling and speeds coverage for walls, floors, and larger outdoor areas.
• Multi-surface compatibility: Works on grout, tile, marble, natural stone, travertine, mosaic and granite without altering surface appearance.
• High coverage: Industry leading 200+ ft2 coverage delivers value for projects that need broad protection.

Who It's For

Homeowners renovating bathrooms, kitchen backsplashes, or laundry rooms who want an easy, low-odor solution will appreciate this sealer. It is also a good fit for contractors or DIYers who need a multi-surface product that works on porous thin set and natural stone while remaining safe for indoor use.

Those who need a colored or glossy finish, or who prefer solvent-based penetrating sealers for very specialized commercial substrates, should look elsewhere; this product is designed to be invisible and water based to avoid changing tile color or introducing fumes.
