webertec 915 2K Powder Component 2kg

webertec 915 SG 2K Powder Component

Attention: Before applying webertec 915, the substrate must be primed with weberprim 901. As a primer for bituminous thick coatings, webertec 901 should be diluted with water in a ratio of 1:10 and applied to the previously cleaned substrate.

Polystyrene-filled flexible 1- or 2-component bituminous thick coating

Application Area

For ground-level waterproofing of basement walls, floor slabs, foundations. Also for bonding polystyrene foam boards.

Consumption

Coverage: Weatherproof non-ponding water min. 40 lm, non-ponding water min. 40 lm, ponding water min. 55 lm. As plate adhesive with non-ponding water approx. 2 lm

Substrate Preparation

• The substrate must be frost-free, firm, clean, sufficiently dry, and free of tar, pitch nests, and open cracks, as well as ridges and other contaminants.
• Water-repellent and adhesion-reducing components must be removed.
• Edges should be broken, and corners rounded.
• Joints and depressions greater than 5 mm should be sealed with webertec 933.
• Radius 5 cm rounded at floor-wall joints with webertec 933.
• Before applying the thick coating, critical areas at the floor-wall transition should be protected against moisture ingress with webertec 933 Hohlkehlenspachtel HKS.

Processing

Priming

webertec 901 is diluted with water in a ratio of 1:10.

Porous concrete and sandy substrates should be primed with weberprim 801.

Mixing for 2-Component Processing

Base mass and powder component are proportionally matched and mixed to a homogeneous, lump-free mass using a stir paddle No. 4.

Crack Filling

To seal pores, cavities, and open joints up to 5 mm wide, a full-surface crack filling with the thick coating should be performed. The crack filling must not be disturbed by the subsequent waterproofing layer.

Sheet Waterproofing - Wall

The process is carried out in at least 2 coats. The second coat should be applied as soon as the first is no longer tacky. For rising groundwater, webersys 981 is incorporated into the fresh waterproofing layer after the first application.

Sheet Waterproofing - Floor

For waterproofing against ground moisture, the coating is applied in two work steps on the floor slab. After drying, a two-layer polyethylene foil is laid as protection and slip layer, and the floating screed is applied on top. For waterproofing against rising seepage water, the coating is applied on the clean surface layer.
