Yes, you can glue tiles to a wall, but the right glue depends on the tile type and the wall surface.

Best glue options (by situation)

✅ Tile Adhesive / Thinset (Best & Standard)

  • Use for: Ceramic, porcelain, stone tiles

  • Wall: Cement board, concrete, plaster, brick

  • ¿Por qué? Strong bond, moisture-resistant, long-term durability
    👉 This is what professionals use.

✅ Construction Adhesive (Small areas only)

  • Ejemplos: Liquid Nails (Heavy Duty), PU construction adhesive

  • Use for: Small backsplash, decorative tiles

  • Avoid: Wet areas (showers), large tiles
    ⚠️ Not ideal for full walls — tiles may shift over time.

✅ Polyurethane (PU) Adhesive / Sealant

  • Use for: Heavy tiles, uneven surfaces, vibration-prone areas

  • Pros: Very strong, flexible, waterproof

  • Cons: Hard to adjust once set
    👉 Often used in industrial or renovation projects.

❌ Do NOT use

  • Silicone sealant ❌ (not structural)

  • Wood glue ❌

  • Hot glue ❌

  • General-purpose glue ❌

Wall surface matters (very important)

Wall Type OK to Glue? Notes
Concrete / Brick ✅ Best Prime if dusty
Cement board ✅ Best Ideal for bathrooms
Painted wall ⚠️ Risky Sand & prime first
Drywall ⚠️ Limited Only light tiles
Wallpaper ❌ No Remove first

Quick step-by-step (correct way)

  1. Clean wall (dust, grease, loose paint)

  2. Prime if needed

  3. Apply adhesive with notched trowel

  4. Press tile firmly (twist slightly)

  5. Use spacers

  6. Let cure 24–48h

  7. Grout after full set

Quick recommendation (TL;DR)

  • Bathroom / kitchen wall: 👉 Tile adhesive (thinset)

  • Small DIY area: 👉 Construction adhesive or PU adhesive

  • Heavy tiles: 👉 PU adhesive + mechanical support while curing
