Tips:

• Work in small sections to prevent mortar from drying before tile placement.
• Only apply enough mortar you can cover with tiles within 10–15 minutes.

💡 Pro Tip: Modified thin-set mortar with polymer additives is recommended for better adhesion, flexibility, and durability.

🎨 Step 4: Placing the Tiles

Correct placement ensures level, even tiles that last for years.

Steps:

1. Set the First Tile: Press firmly into the mortar, twisting slightly for a better bond.
2. Use Tile Spacers: Place spacers between tiles to maintain consistent grout lines.
3. Check for Level: Use a level to ensure tiles are flat and even with each other.
4. Continue Tiling: Work outward from the center, maintaining straight lines and consistent spacing.
5. Cut Tiles as Needed: Use a tile cutter or wet saw for edge or corner pieces.

💡 Pro Tip: Tap tiles gently with a rubber mallet to ensure full contact with the mortar and remove air pockets.

⏳ Step 5: Allowing Mortar to Cure

Patience is key for a durable installation.

Steps:

1. Let the mortar set for 24–48 hours or as recommended by the manufacturer.
2. Avoid walking on or disturbing the tiles during curing.

🛠️ Step 6: Grouting the Tiles

Grout fills the gaps between tiles, securing them and preventing debris or moisture penetration.

Steps:

1. Mix Grout: Follow manufacturer instructions for the right consistency.
2. Apply Grout: Use a rubber float to press grout into the spaces between tiles.
3. Remove Excess Grout: Hold the float at a 45-degree angle and scrape off excess grout.
4. Clean Tile Surface: Wipe tiles with a damp sponge to remove grout haze.
5. Allow Grout to Cure: Typically 24 hours, depending on brand and environmental conditions.

Tips:

• Use sanded grout for joints wider than 1/8 inch.
• Unsanded grout works best for narrow joints.
• Seal grout after curing to prevent staining or water absorption.

💡 Pro Tip: Work in small sections to prevent grout from drying too quickly and creating uneven joints.

🔥 Step 7: Sealing the Tiles and Grout

Sealing adds protection and enhances longevity.

Steps:

1. Select a Sealer: Choose a penetrating or surface sealer depending on tile type.
2. Apply Evenly: Use a clean brush or applicator to cover grout and tile surface.
3. Let Dry: Allow sealer to cure according to manufacturer instructions.
4. Optional Second Coat: Provides additional protection for high-traffic areas.

💡 Pro Tip: Sealing is particularly important for bathrooms, kitchens, or basements to prevent moisture damage.
