Thin underlay with integrated vapour barrier
Low installation heights and high requirements do go together. The SELITPRO® HD 1.5 mm AquaStop proves this. Despite its low thickness, it also protects your floor from high loads. Also impressive: the significant reduction in walking sound. To prevent residual moisture from causing damage, the SELITPRO® HD 1.5 has an integrated vapour barrier. It is also suitable for vinyl floors.
Heavy-duty film with mineral filling - Ideal for underfloor heating
Before installation, please note: check the base in accordance with CEN/TS 14472 and ensure that the quality of the base is 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. 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.
Cleaning the surface
Cleaning the surface
Step 1 Clean the surface thoroughly with a brush or vacuum cleaner. Remove any adhesive and paint residues completely.

Step 5 Lay the laminate in the same orientation as the underlay. Observe the manufacturer’s instructions and do not place any load on the underlay. If necessary, place the laminate board under your knees/feet to distribute the load.

Step 6 Repeat steps 2 – 5 until the entire floor has been installed. Tape the joints with the Aluminium-Foil Sealing Tape to make them vapour-tight.
