Quiet, quieter, Selitac 3 mm AquaStop
Do you like it quiet? SELITAC® 3 mm AquaStop ensures a significant reduction in impact and walking sound. Your neighbours will certainly appreciate that. The underlay also protects your floor from damage caused by heavy loads and falling objects. The integrated vapour barrier prevents rising moisture.
Polystyrene foam with high level of compressive strength - ideal for rooms with poor soundproofing
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 flooring in the same orientation as the underlay. Do not place any load on the underlay. If necessary, place the board under your knees/feet to distribute the load.
Finishing the installation

Step 6 Repeat steps 2 – 5 until the entire floor has been installed. Connect the individual panels of the underlay using the easy click® contour. Seal all joints with the Aluminium-Foil Sealing Tape to make them vapour-tight.
