Long answer: Believe it or not there are more uneven walls and floors than there are even ones. Tilers and DIYers have been battling this problem for years and although it can be a nuisance if you aren’t expecting it – it is possible to achieve a smart, flat surface for you to tile on.

 

Plastering: Level Those Uneven Walls

Plastering the walls is the best way to ensure that the walls are nice and even and ready for you to tile on. It can be worth getting a professional plasterer in to complete the task, as plastering is a difficult skill to master and plastering a perfectly flat, even surface is not for beginners.

Backer Boards

A Concrete Backer board can cover up an uneven wall with ease. At Walls and Floors we recommend HardieBacker Boards as they are mould and moisture resistant, easy to work with yet remain sturdy in their lifespan. The Backer provides a flat even surface that can be screwed into the wall and cover over any uneven problem areas.
It is wise to attached them to strong support areas as the concrete boards and tiles weigh a lot and you run the risk of them adding stress to the walls. But they are easy to install and create an instant flat surface for use on walls and floors.

 

Use varying amounts of adhesive

The option of using a varying amount of adhesive is quick and easy. By back buttering the tile and adding adhesive to the surface to pack out the base and raise the tile to the level of the one next to it – just always ensure you have a spirit level and good eye. If this is the option for you, make sure you use a thick set tile adhesive that can survive being built upon.
