In a private house was made a bathroom, which was lined with plywood and painted with olive oil. It needs to be tiled. Can I do this? What kind of adhesive to use?
Plywood can be severely attacked by moisture, even if it was impregnated with oil. Therefore, it is better to put a moisture-resistant gypsum board on the plywood, cover it with primer and lay the tiles with special tile adhesive.
It is better to cover the top with moisture-resistant plasterboard. And lay tiles on top of it.
If you do not want to do this, put a thin net over the plywood. You are making a screed. Then lay the tiles on it with polymer-cement adhesive.
