One bucket of stair adhesive 3.5 kg is sufficient for 3 to 4 steps, it levels out unevenness up to 4 cm and is sound-absorbing. The processing time is about 1 hour. The steps can be walked on immediately. After approx. 4 hours the steps no longer slip.
Attention! Work with disposable gloves!
Pour hardener into the glue bucket.
Stir both components well.
