Can I use “Széria” self-levelling floor screed for thicknesses over 15 mm?
Yes, it can be used for thicknesses over 15 mm if spread in a single coat, but for levelling thicknesses over 10 mm \"Széria\" lightweight estrich is more cost effective, which has the same technical properties as the self-levelling floor screed for thicknesses between 2-15 mm for a considerably lower price.
