Next, you will need to use a wood filler to fill any holes or gaps in the wood; as a result, the surface will become smoother and suitable for applying the adhesive. You need to let the filler dry for an amount of time before you start to apply the adhesive; you can check the instructions of the filler manufacturer to know the required time. 

Second Step

Apply the mastic adhesive to the wood; apply it only over a three-square foot of the wall; you will need to use a notched trowel to apply the adhesive. The thickness of the adhesive should be equal to the thickness of the tile; for example, if the thickness of the tile is ⅕ inches, you need to apply a layer of ⅕ inch thick of the mastic to the wood using the trowel edge to create furrows.

You need to clean up any drips or excess mastic; you will also need to remove any spills resulting while applying the mastic; if the mastic dries, you will need to use a mastic remover. 

Third Step

After the mastic tacks, start installing the tiles on the mastic; while placing the tiles, you need to apply some gentle pressure on them to fix them properly; you can place three to four tiles first, then use a leveler to check the level of the tiles, you can apply some pressure on uneven tiles to even them, you can use a rubber mallet to apply the pressure.

After it dries, you can use a suitable grout to finish the tiles by applying the grout to the joints between the tiles; you can also use a grout floater to remove any excess grout; the floater should be used at 45 degrees from the joint. After the grout dries, you will need to use a wet sponge to finish the grout, so it has a smooth finish.

Tile adhesives are not designed for plastic surfaces; therefore, you can’t use adhesives to install tiles on a plastic surface using normal ways. To tile up a plastic surface, you will need to use a specific type of glue which is silicon-based adhesive; the glue will help the tiles to adhere to the plastic surface permanently.

After the primer dries, you need to apply the adhesive for the tiles; the adhesive can have different types; for example, porcelain uses cement-based adhesive, and ready mixed adhesive is used for ceramic tiles under 300 x 300 millimeters. 

Next, start placing the tiles; while placing the tiles, you need to apply some gentle pressure on them to fix them properly; you can also use a tile spacer to keep the space between joints even. After you finish tiling the wall, you need to let the adhesive dry or cure for an amount of time.

The time taken for the adhesive to dry can differ according to the manufacturer; therefore, you need to check the manufacturer’s instructions.

Then, after it dries, you can use a suitable grout to finish the tiles by applying the grout to the joints between the tiles; you can also use a grout floater to remove any excess grout; the floater should be used at 45 degrees from the joint.

After the grout dries, you will need to use a wet sponge to finish the grout, so it has a smooth finish.

Method Two
Install a stud frame of timber where the centers are far from each other by 300 millimeters; you will need to fix the boards by fixing them in the floor, ceiling, and surrounding walls; this will leave no flexibility for the boards to move. You can either install a tile backer board (12 millimeters) or plasterboard ( 12 millimeters) using screws designed for dry walls; you also have to keep the boards 300 millimeters from each other.

This step is essential for installing insulation inside the stud frame; after achieving a smooth surface, you can now apply a primer to the wall.
