How to prepare and use a tile adhesive on plasterboard

Here are easy step-by-step instructions for preparing an adhesive to apply tiles on a plasterboard wall:

Preparation of the glue

Generally tile adhesives are prepared by mixing 1 liter of water for every 3.5 kg of product.

To mix this mix you can use a professional mixer or more simply a low speed drill.

The result that will be sought will be a plastic and homogeneous mixture.

When the dough appears as described above, leave it to rest for 10 minutes and then mix again.

The results obtained can be used up to a maximum of 6 hours.

How to use and apply it

• Spread corrugated cardboard and cover sheets on the ground to protect the flooring;

• Wear protective gloves and a professional P1 type mask;

• Apply a first layer of adhesive on the support with the smooth part of the spatula. N.B: always respect the correct adhesive thicknesses required according to the work being carried out;

• Spread the adhesive with the toothed part of the spatula;

• Position the tiles making them adhere well. If necessary, tap lightly on the tile to ensure its correct "grip".

• Follow the tile assembly scheme indicated in the article on this site "TILES GUIDE ON PLASTERBOARD";

• If the adhesive tends to form a sort of surface film, do not absolutely wet the adhesive with water. Proceed with a new spreading of another layer always troweling with the notched part of the trowel;

• Check the positioning of the tiles and make corrections within 30 minutes of laying, before the adhesive takes effect;

• At the end of the work, clean any traces of glue on the tiles.

CAUTION:

Here are some useful tips to avoid making mistakes when laying and to obtain the best possible result:

• If the tiles to be laid are large or subjected to particular mechanical stresses, it will be necessary to apply the adhesive (approximately 2 mm thick) also on the back of the tiles to guarantee a "double seal".

• Preferably use the plasterboard with the green colored sheet as it is designed to be applied in damp environments such as bathrooms or kitchens.

• Check the weight of the tiles, as the sheet of plasterboard over the years may weaken or undergo deformations caused by too much load.

• Check that the glue, in addition to being elastic, is also resistant to humidity and water, in fact usually a tiled wall is made in a bathroom or more generally in damp environments.

• Pay attention every 5/6 tiles to their positioning and do not wait for the adhesive to solidify because then it will no longer be possible to make changes to the wall.

CAUTION:

The advice to get an optimal job is to contact a highly specialized company that can help you.
