When installing tiles on a bathroom wall with old cracked drywall and no studs where the tiles go, using liquid nails or adhesive can be a common solution. However, if you're looking for alternative methods, here are some options:
Backer Board: Instead of applying tiles directly to the drywall, you can install a cement backer board (such as HardieBacker or Durock) first. Backer boards are more stable and moisture-resistant than regular drywall, providing a suitable surface for tile installation. They can be attached to the existing drywall using screws and construction adhesive.
Mastic or Thinset Mortar: Instead of liquid nails, you can use tile mastic or thinset mortar as the adhesive. These materials are specifically designed for tile installation and offer better bond strength than liquid nails. Apply the mastic or mortar directly to the backer board and then press the tiles onto it.
Tile Mat or Tile Membrane: Tile mats or membranes are adhesive sheets designed for tile installation. They provide a flexible and waterproof surface for tiling. You can apply these directly to the drywall or backer board and then install the tiles on top.
Furring Strips: If the existing drywall is in poor condition but still structurally sound, you can add furring strips over the drywall. These strips can be attached horizontally, providing a flat and secure surface to install the tiles.
Remove and Replace Drywall: While it's a more involved option, if the existing drywall is severely damaged or compromised, you can remove it completely and install new drywall or backer board before tiling.
Before proceeding with any alternative method, ensure that the surface is clean, free of dust, and properly prepared. Also, consider using appropriate safety equipment, such as a dust mask and safety glasses, especially if you need to remove old drywall.
Keep in mind that while some of these alternatives may provide solutions for tiling on damaged or stud-less walls, it's crucial to follow proper tiling techniques and use the right materials to ensure a long-lasting and successful installation. If you're uncertain about the best approach for your specific situation, consulting with a professional tiler or contractor is highly recommended.
