Koester - Dachflex flexible roof coating

A flexible, solvent-free roof coating. Designed for dry and slightly moist surfaces. After setting, the material is very flexible, waterproof, vapor-permeable, resistant to UV radiation and frost.

Properties

• ease of use (one-component product)
• seamless seal
• very good adhesion to many construction substrates
• resistant to weather conditions
• used as a layer reflecting UV rays
• reduces energy consumption for air conditioning
• solvent free

Application

• prophylactic protection and sealing of flat roofs, e.g. with bituminous material, know-cement boards, concrete boards
• flat roofs over unheated rooms (e.g. garages)
• protection of scratched wall surfaces, e.g. plaster in cement ones
