Renovating bathrooms with plaster

Renovating some bathrooms with a certain age we can find that the ceramic was placed on a plaster trim.

To re-glue the new tile on these walls and not have problems, you must first apply a special fixative for absorbent supports, which creates an insulating film neutralizing the possible absorption of the plaster with mortars and mineral adhesives. Two coats of the product mixed with water are recommended in the proportion indicated by the manufacturer. We can use a brush or roller on the wall to be tiled and by waiting a few hours we can perfectly place the new tile with a conventional glue cement.
