Variants
Can be used on saline and problematic surfaces
- Can be used on sandstone
- Wide range of applications, one product for many applications
- High application reliability
Can be used on surfaces in old and new buildings
Wide range of applications, therefore easy, safe use on construction sites
Penetrates surfaces well
- Has a strengthening effect deep into the surface
- Stabilises the surface
- Creates an adhesive bridge between the surface and the seal
- Reduces pores, thereby prevents salts from re-forming on the wall surface
- Effective at protecting the surface against chemical and mechanical stresses
Ready for use, fast-drying
Can be applied directly, does not need to be stirred or thinned, resulting in secure, time-saving application
Solvent-free
Glass surfaces (windows or similar) must be protected from contact with the building waterproofing system primer coat, as contact may cause discolouration. During application, we recommend using personal protective equipment (safety goggles/gloves) occupational safety reasons. Clean with water immediately after use.
The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result.

Suitable for mineral surfaces (except for plaster), mortar, mineral plaster, cement-based sludge, brick, sand-lime brick and concrete in the areas of renovations and new buildings. Can be used in the Würth building waterproofing system to strengthen the surface and as an adhesion agent when bituminous (art. no. 0893 212 115/0893 212 120) and cement-based seals (art. no. 0893 212 125) are used. For reducing water absorption; also suitable for problematic surfaces such as sandstone.
The surface must be free from oil, and must be cleaned of loose components. Salt efflorescence must be removed with a brush. Apply undiluted primer to the surface to be coated using the swab, brush or roller. The areas must be saturated to achieve effective priming. Highly absorbent surfaces (e.g. aerated concrete) must be primed twice. The primed surfaces can be worked with bituminous seals after approx. 12 hours and with cement-based seals after approx. 30 minutes.
