ARDEX WPM 400

ARDEX WPM 400 is a hot-applied, highly elastic 100% pure polyurea waterproofing membrane, with high mechanical and chemical resistance. Once dry, it forms a continuous waterproof membrane, without joints or need for overlap or reinforcement. It provides permanent elasticity, even at very low temperatures, and is able to absorb substrate movements.

The rapid polymerisation of ARDEX WPM 400 means it can adapt to any surface and attain waterproofing properties within three hours (optimal properties are achieved in 24 hours).

Note: ARDEX WPM 400 is not stable when exposed to UV rays, resulting in a major change in colour: to protect ARDEX WPM 400 from UV, use ARDEX WPM 400 Finish aliphatic polyurethane coating.

Use:

• Waterproofing balconies, roofing, terraces
• Floors requiring both substrate waterproofing and high mechanical & chemical resistance
• Waterproofing metallic roofs
• Pool and pond waterproofing
• Waterproofing tanks & irrigation channels
• Encapsulation of fibre cement roofing
