6 Common Grouting Mistakes to Avoid
Grouting is the final step that completes your tile project, but it’s easy to get wrong. Avoid these common mistakes to ensure a durable, professional-looking finish:
1. Not Letting the Tile Set Before Grouting
Grouting too soon can cause shifting or poor adhesion. Always wait 24–48 hours after tiling to let the mortar or adhesive fully cure before applying grout.
2. Using the Wrong Grout
Choosing the wrong grout can lead to cracks, poor bonding, or scratched tile surfaces.
- Sanded grout (contains fine sand): Best for joints over 1/8 inch wide. It’s durable, but can scratch delicate tiles like glass or polished stone.
- Unsanded grout (no sand): Ideal for narrow joints under 1/8 inch and scratch-prone tiles. It’s smoother and safer for sensitive surfaces.
3. Mixing Grout Incorrectly
Consistency is key. Follow package instructions for ratios and rest times, and use a corded drill or proper mixing tool to avoid clumps or air pockets.
4. Applying Grout Incorrectly
Hold your grout float at a 45° angle and apply diagonally across tiles. Wipe at the right time, not too early, or you’ll wash out fresh grout.
5. Skipping Grout Sealer
If your grout isn’t pre-sealed, apply a sealant to protect it from moisture, stains, and mold, especially in wet areas.
6. Choosing the Wrong Grout Color
Grout color defines the tile’s final look. Test your color first it can either highlight the tile or clash with it completely.
