Drainage Mortar vs Screed: Best Choice for Patio
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 completely water-permeable structure, because the water can drain better and there is no risk of moisture damage when freezing or heating up. For finishing, the drainage mortar can be covered with a few millimeters of screed and left exposed, provided that all loose granules are removed before tiling. The employee recommends using screed from Knauf or Weber. For the tile joints and adhesive, the employee recommends flexible silicone grout and S1 tile adhesive.
