Drainage mortar vs Screed: Best Choice for a Terrace
A customer has questions about the use of drainage mortar and screed for the substrate of his terrace. A Staenis employee advises that drainage mortar is a better option than screed for a fully water-permeable structure, as water can drain away better and there is no risk of moisture damage during freezing or heating. For the finish, the drainage mortar can be covered with a few millimeters of screed or left exposed, provided all loose grains are removed before tiling. The employee recommends using screed from Knauf or Weber. For the tile joints and adhesive, the employee advises flexible silicone grout and S1 tile adhesive.
