Sealing Plaster Walls Before Tiling

Tiling onto plaster backgrounds.
Sealing plaster walls before tiling. Make a gauge rod using a length of straight timber. Before you get to it you should level the bathroom the kitchen and or the hallway walls. Plaster is a weak material compared to brick and cement. You should not tile over wallpaper glossy surfaces lead paint or plywood.
There are specific wall primers designed to take tile adhesive from bal etc but if you are on a budget then mist coating will be fine. You can tile over a wide range of surfaces and textures but wall preparation is absolutely crucial. To prepare your walls for tiling is rather simple as long as you have the right know how mindset patience and tools. One handy tip my father in law taught me three years ago was if you plan on tiling a wall and the wall is uneven then the plastering doesn t need to be abs.
However tiling over tile can add quite a bit of thickness so make sure your wall can handle the weight. Tiling should be set out from the centre of the walls either the centre of a tile or the joint between two tiles positioned in the centre of the wall whichever of these two options avoids small cuts of the tiles. Make a mark on the wall with your starting point. If you re not sure if you have lead paint test kits are available.
If you are using a cement based adhesive then you will need to prime the plaster with a suitable primer i personally only use weber pr360 it is a acrylic primer and i use this type of adhesive on all walls now apart from on kitchen walls with small tiles then i will use tubbed adhesive.
