Two-layer Composite waterproofing kit "WILOTEKT-PLUS" / ETA-03/0049/ CE
1. Rough concrete structural ceiling
Clear of sharp surface irregularities
without large depressions (2-3 cm in diameter)
free of substances which reduce adhesive grip (e.g. oil, grease).
2. Preparation of the concrete surface
Remove sharp surface irregularities. Sweep surface with a stiff broom and clear all dust and particles. Use relatively small depressions to calculate minimum amount required. Adhere to minimum coverage of 2,5 kg/ m2. Fill relatively large depressions with "WILOTEKT-Elastomerbitumen" polymer-modified unfilled bitumen compound to level the surface and add to required quantity calculation.
