A good base for rooms that are used less often
The BASIC 1.6 mm is suitable for rooms with less footfall. Available as a roll, it protects against loads, reduces impact sound by up to 17 dB and compensates for minor unevenness. Its low thickness makes it a good solution for low installation heights.

Installing BASIC 1.6 mm –
a step-by-step guide
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.
Step 1
Clean the surface thoroughly with a brush or vacuum cleaner. Remove any adhesive and paint residues completely.
Step 2
Mineral bases need protection against rising moisture. Cover the room completely with SELITstop® Comfort Vapour Barrier. Allow the joints to overlap by approx. 5 cm and seal them in a vapour-tight manner with SELITstop® Aluminium-Foil Sealing Tape.
Step 3
In the wall connection area, place the film in a trough-like position at approx. 3-4 cm to protect against moisture and fix to the wall with SELITstop® Aluminium-Foil Sealing Tape. Alternatively, use SELITstop® Moulding Protection Belt. In this case, install the moisture protection film flush with the wall.
Step 4
Lay the first panel of the underlay over the entire width of the room.
Step 5
Lay the flooring in the same orientation as the underlay. Do not place any weight on the underlay, if necessary place the panel under your knees/feet to distribute the load.
Step 6
Repeat steps 4 to 5 until the flooring has been installed throughout the entire room.
