Load-resistant 2K PUR assembly foam - adhesive "StairMaster".
Two-cylinder cartridge for efficient installation of steps, risers and window sills.
Processing:

• the surfaces to be glued must be load-bearing, dry, clean and free of oil and grease;
• when gluing windowsills to plaster or aerated concrete walls, they must be pre-treated with KLEIBERIT Primer 835;
• when gluing linoleum or PVC floor coverings on stairs, remove wax, oil, etc. in advance and sand the surface;
• wooden parts must be sanded to remove paint residues;
• items such as steps, door sills or windowsills must be secured with a distance adjustment device or spacers that allow for a 5" expansion groove, 15mm wide;
• remove the parts to be glued, apply the adhesive strips lengthwise or laterally at a distance of 8-10 cm from each other, place them back on the distancing device as soon as possible.

Open time: approx. 2 minutes (allows for adjustments).
If possible, the parts to be glued should be evenly loaded with approx. 80 kg/m². Items such as steps, window sills and door thresholds should be loaded with two 15 kg weights per spacer.
The foam can be cut after 8-10 minutes.
The steps can be used after approx. 20 minutes.
