Installing 1 mm –

a step-by-step guide

Before installation, please note: The base must be tested according to CEN/TS 14472 before the floor is installed. The base must be suitable for proper processing. In general, the base should be clean, level, dry, resistant to tension and compression and should not contain any substances such as plasticisers, solvents or other diffusing substances. Textile floor coverings must be removed before installation in principle. Installation on ceramic tiles, linoleum or wooden floors is only possible with restrictions as this may mark the base. It must be ensured that the base is in a state of equilibrium humidity and that the CM value is below 2.0 % (for cement screed) or below 0.5 % (for anhydrite screed and anhydrite flowing screed).
The processing instructions of the flooring manufacturer are to be observed as binding specifications.
