Tiling Very Uneven Walls

The mortar is spread.

Tiling very uneven walls.

One of the best ways to ensure the surface of a wall is even is to plaster it. Being that she s not going to be there very long that might be fine. If you don t think you can trowel a coat of mortar to get it even withing about 1 4 the tiles will further even it out when set i would investigate a possibility of mounting a cement board onto the bricks instead. The board will create a perfect backing that will make setting tiles on thinset look like a walk in a park.

Back buttering is a trick used for tiles of uneven thickness like ungauged slate or handmade tiles extremely large tiles or for tiles being installed on an uneven surface. There is also a spot near the window trim where the wall appears to be built up too much enough so that the tile could end up proud of the trim which i m pretty sure won t look so hot. Plastering a wall can be a super straight forward task but if you have no prior plastering experience it may be worthwhile getting a professional in to help achieving a perfectly flat surface for tiling is essential and this isn t always easy on your first attempt. If you put a 48 straight edge up against the most sunken areas there s a gap of almost a 1 2.

One very big problem that not many people realise if the wall isn t really flat a brick joint pattern will show off every out of plane point in the wall by virtue of sticking out a half tile from the tiles above and below it. The problem is that the wall is uneven.
