Why Grout Sealing Shouldn’t Be Overlooked

Grout stands as the vulnerable link in tile installations—its porous structure absorbs spills, grime, and moisture. By sealing grout correctly, you protect your surfaces and save money on cleaning and repairs. For three decades, This Old Grout has helped homeowners fight stains with professional-grade grout sealer solutions that are both easy to use and long-lasting.

What Is Grout Sealer — And Why It Matters

Grout sealers act like invisible shields. They fill microscopic pores and block water, oils, and dirt. In high-traffic areas—such as kitchens, bathrooms, and countertops—sealed grout prevents discoloration and microbial growth. Plus, sealers make cleaning effortless and protect your grout long-term.

Common Mistakes That Undermine Grout Sealer Performance

1. Skipping thorough cleaning first
   Applying sealer over dirty grout traps residues that block penetration. Instead, clean deeply using This Old Grout’s tile and grout cleaners, then let the surface dry completely.

2. Sealing too soon after installation
   Fresh grout cures over time and releases moisture—seal only after 48–72 hours. Otherwise, the sealer can’t bond effectively.

3. Using the wrong sealer type
   Choose solvent-based sealers for unglazed natural stone and water-based fluoropolymers for most ceramic and porcelain tiles. This Old Grout offers a range of sealers designed for specific conditions.

Step‑by‑Step: Correct Grout Sealer Application

1. Deep Clean and Dry

Use tile cleaners to remove film, soap scum, and residues. After rinsing, let the grout dry for at least 24 hours or use a moisture meter.

2. Choose the Right Product

Select a penetrating, breathable sealer from This Old Grout’s line-up. Refer to product labels for coverage and recommended uses.

3. Apply Evenly—Don’t Rush

Use a brush or roller to coat grout lines thoroughly. Wipe off excess from tile surfaces to avoid residue. Apply two coats if recommended.

4. Allow Adequate Cure Time

Let the sealer cure per manufacturer guidelines—typically 24 hours. Avoid contact with water during this period.

5. Test and Top Up

Do a water drop test—if water beads up, your grout is protected. Depending on foot traffic and wear, reseal every 1–3 years.
