A shower leak means that water found a way through the grout. It can be caused by a discharged outlet that is not dense or has a crack or leak in the pipes. If you suspect any of these problems, you need a professional plumber. After the plumbing is repaired and the tiles or grout is replaced, you can begin the drying process using a fan in the bathroom and by leaving the windows wide open. Be patient because it can take weeks before everything is completely dry.

You will notice that the cement has gone a light gray color. Test that the wall is completely dry by pasting a piece of plastic over the affected area and leaving it overnight. If there are drops of water on the plastic in the morning, you will still have to wait a while until there is no more moisture. It is important that you apply a waterproof barrier on the walls before you tile. You can also use a waterproof bonding agent.

    • Hi Lucy, thank you for getting in touch with us. Unfortunately, no, Plascon does not advise any of our products to be used in a shower as the product is not designed to withstand the water and heat in a shower.
