SELITBLOC® ULTRA even provides underlayment with a particularly high compressive strength of 1,000 kPa that is commonly used for special-purpose flexible vinyl click flooring.
High-performance polyolefin foam underlay (XPO)
Extreme compressive strength of 1,000 kPa for maximum resistance
Efficient impact and radiated walking sound reduction
deally for floor heating
Plasticiser resistant, thus suita- ble for all vinyl click floorings
Before laying on mineral surfaces 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).
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.

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 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.
