Humans have been using stone and decorative tiles to enhance their homes for thousands of years. With such a rich history, it’s no wonder there are so many beautiful options available today—from intricate natural stone mosaics to sleek modern porcelain.
Whether you choose natural stone tiles or porcelain, protecting your investment is key. Sealing your tile acts as an extra layer of defense against everyday wear, spills, and moisture. But do you always need to use a tile sealer? Read on to find out!
Do Both Tile and Grout Need a Sealer?
Understanding the difference between sealing grout and sealing tile is essential for a successful installation:
-
Grout: Grout should always be sealed because it is extremely porous. Sealing grout prevents moisture buildup, staining, and mold, making it significantly easier to keep clean over time.
-
Tile: Sealing tiles is a separate step. While it protects against dirt and water penetration, not all tiles require a sealer.
How Do I Know if My Tiles Need a Sealer?
Needing a sealer depends entirely on the material and finish of your chosen tile:
1. Ceramic & Porcelain Tiles (No Sealer Needed)
Porcelain and ceramic tiles—such as our Bamboo, Arlington, or Elda series—are kiln-fired at ultra-high temperatures. This process creates a non-porous, highly dense surface with a built-in protective coating. They do not require a tile sealer!
2. Natural Stone & Micro-Pebble Mosaics (Sealer Recommended)
Natural stones (like marble, limestone, and natural pebbles) are inherently porous. Products like our Lovina Micro Pebble collection feature raw, unpolished stone textures. Applying a penetrating sealer to natural stone helps:
-
Prevent deep stains from oils, soaps, and colored liquids.
-
Enhance the rich, natural color of the stone (giving it a subtle sheen or "wet" look).
-
Extend the lifespan of your installation.
Pro Tip: Always test your sealer on a small, inconspicuous area or a loose sample tile before applying it everywhere to make sure you love the final finish!
When and How to Seal Your Tile
If you're working with porous natural stone, timing is everything.
When to Seal:
-
Before Grouting: It is ideal to seal porous tiles before applying grout. This prevents dark grout pigments from staining the raw stone surface during installation.
-
After Grouting: Once your grout has completely cured, apply a final coat over both the tile and the grout lines. This locks out moisture and re-seals any areas worn down during the grouting process.
How to Apply:
-
Clean Thoroughly: Remove all dust, dirt, and construction debris. Mop or wipe the tiles with mild soap and warm water.
-
Let it Dry: Rinse with clean water and let the surface dry completely for at least 6 to 12 hours.
-
Apply the Sealer: Using a clean sponge, microfiber cloth, or low-pressure sprayer, apply an even coat of penetrating stone sealer.
-
Wipe Excess: Allow it to absorb for 5 minutes, then wipe away any excess sealer sitting on the surface.
-
Reapply if Needed: For heavily textured stones, apply a second coat after 30 minutes.
Do I Need to Reapply Sealer?
Yes, natural stone surfaces typically benefit from re-sealing every 1 to 2 years, depending on foot traffic and exposure to water.
-
The Water Drop Test: To check if it’s time to re-seal, spill a few drops of water onto your tile. If the water beads up, your seal is intact! If it darkens the stone and absorbs quickly, it’s time for a fresh coat.
