How to fix cork tiles to a plasterboard wall
A solvent-free grab adhesive works for cork tiles on plasterboard, but the board must be sealed first or it pulls the moisture out of the adhesive and the tiles drop off.
The short answer
Seal the plasterboard with a diluted PVA primer or an acrylic sealer, let it dry, then fix the tiles with a solvent-free grab adhesive applied in blobs and combed out. Bare plasterboard paper is very absorbent and drinks the water out of a water-based adhesive before it can develop grip, which is the usual reason cork tiles fall off a new wall. Sealing takes half an hour and fixes it.
- Difficulty
- Moderate
- Time needed
- 1 to 2 hours for a wall, 24 hours cure
- What you need
- Solvent-free grab adhesive, fine notched spreader, diluted PVA or acrylic primer, chalk line, sharp craft knife and straight edge, laminate roller, tape measure
Two separate problems have to be solved here and most failures come from only solving one.
The first is suction. Plasterboard's paper face pulls water out of anything applied to it. A grab adhesive that has lost its water too quickly skins over without ever wetting the tile, and the tiles come away with clean adhesive still stuck to the wall. A sealer coat evens the suction out.
The second is the tile itself. Cork is light, which helps, but it is also compressible and absorbent. Do not use a solvent-based contact adhesive on a whole wall of it in a closed room, and do not use so much water-based adhesive that the tile swells. A thin combed layer is better than blobs alone, because blobs leave voids behind the tile that show as hollow spots when you press them.
Plan the layout before you start. Cork tiles are usually not perfectly square and the edges are soft, so set out from the centre, keep the joints tight, and cut the perimeter tiles last.
Step by step
- Check the plasterboard is sound and firmly fixed, and fill any deep dents.
- Seal the wall with diluted PVA or an acrylic primer and let it dry completely, usually a couple of hours.
- Find the centre of the wall and set out your tile layout with a chalk line so the cut tiles fall at the edges.
- Apply solvent-free grab adhesive to the back of each tile and comb it out with a fine notched spreader.
- Press each tile onto the wall and slide it slightly to bed it, keeping the joints tight to its neighbours.
- Work across the wall from the centre outwards, checking alignment every few tiles.
- Cut the perimeter tiles with a sharp blade against a straight edge.
- Roll the whole wall over with a laminate roller and leave it 24 hours.
What to avoid
Do not fix cork onto bare unsealed plasterboard. The board takes the water and the adhesive never grips.
Do not use blobs of adhesive alone. Cork is thin enough that the voids show through as hollow patches.
Do not use a solvent-based contact adhesive for a whole wall indoors. The vapour build-up in a closed room is genuinely unpleasant and hard to clear.
Cork fixed with grab adhesive is effectively permanent, and removing it will take the plasterboard's paper face with it. If the wall may be redecorated later, that is worth knowing before you start. Check for cables and pipes before fixing anything into the wall.
