Sturdy wood flooring on cement and calcium sulphate screeds
Today, elastic bonding is state of the art in wood floor bonding. It helps diminish shear forces and durably prevents the development of tensile stresses in the substrate – over the whole product life cycle. The choice of wood flooring very much depends on the client's taste and on the availability of suitable flooring in the respective region or country.
Application
Substrate preparation
Clean the cement screed and bind any residual dust by priming the substrate with R 777 Dispersion Primer. Instead, it is also possible to use R 766 Multi-Purpose Primer which can be applied on nearly every absorbent and nonabsorbent substrate. Thanks to its high concentration, it can be diluted up to a ratio of 1:4 and thus ensures a high yield. Another benefit: R 766 dries really fast (0-30 minutes).
Floor levelling
Produce a level surface with DX Universal Levelling Compound (24 hours) or XXL XPRESS Rapid Levelling Compound (90 minutes).
Installation of flooring
For bonding the wood flooring, use either P 625 2C PUR Adhesive or P 685.
