2.2 mm

All-round talent for your floor
One product for almost everything. SELITPRO® 2.2 mm reliably protects your floor from the stresses of walking across it and heavy furniture and prevents damage caused by falling objects. For a lower noise level, it reduces walking and impact sound and decreases the latter by up to 21 dB. Do you like to have warm feet even in winter? The SELITPRO® 2.2 mm works very well with underfloor heating.

Installing 2.2 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.

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.

Applying the moisture protection

Applying the moisture protection

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.

Masking the wall connection area

Masking the wall connection area

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.

Laying out the first panel

Laying out the first panel

Step 4
Lay the first panel of the underlay flush with the wall over the entire width of the room with the cutting grid facing upwards.

Installing the flooring

Installing the flooring

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.

Installing the rest of the flooring

Installing the rest of the flooring

Step 6
Repeat steps 4 to 5 until the flooring has been installed throughout the entire room. Connect the individual panels of the underlay using the easy click®+ contour.
