Buying Guide
What should you consider when choosing grout stain and sealer products?
- Grout type compatibility: Check if the product works on sanded, unsanded, cementitious, or epoxy grout to ensure proper adhesion.
- Coverage: Most 8 oz bottles cover several hundred square feet; plan for your tile area and consider whether you’ll need more than one coat.
- Color goals: Decide whether you want a color refresh, a darker shade, or a lighter tone to match tile aesthetics.
- Finish and protection: Look for colorants that also seal to resist moisture and stains, especially in bathrooms and kitchens.
- Application method: Applicator tips and markers can affect precision on small or intricate grout lines.
- Exterior vs interior use: Some products specify interior/exterior suitability; plan accordingly for areas exposed to weather.
