The most common option of laying piece parquet is the use of cold and hot mastic as a link with the base of the floor. Shields that have a thickness of 27 mm (more can) and parquet boards with a thickness of about 22 mm are laid along wooden lags. Shields and boards having a lower thickness are laid on a continuous screed without lag from soft wood -fiber plates. The value of the alleged loads and the type of inter -story floor affect the choice. Screed, t.e. base for the coating should be even and horizontal.
