Tiles coming off swimming pool sides and bottom

Cause

Wrong tiles/adhesive

Repair

  • if the tiling is relatively new (installed within the last few years) and was carried out by a tradesperson or company, call them back to fix the problem

  • all loose tiles will need to be removed and thoroughly cleaned before being refixed

  • refix the tiles using an appropriate mortar or adhesive, following the instructions of the manufacturer. Traditional thinset mortars often require the pool water level to be lowered to the point where the retiling areas is dry. Some adhesives are available that can be applied underwater (in chlorinated water) and will cure without the pool needing to be drained

Cause

Concrete shrinkage

Repair

  • as above. Refixing should not be carried out until the concrete is properly cured and the shrinkage has finished
