Application
Applications
  • Waterproofing of wet areas, foundations, basements, terraces, retaining walls, inverted roofs etc
  • For waterproofing terrace garden and podium
  • Other roof structures when protected from exposure to direct sunlight, for longer life
Application
Advantages
  • TRU PU is a single component liquid system and very easy to apply
  • High elasticity ensures a permanently flexible barrier over a wide range of temperatures
  • Outstanding resistance to oxidation and brittlement
  • Gives better adhesion. Can be applied to a range of substrates
  • Good crack bridging capacity up to 2 mm
  • Good retention capacity
How to use
How to use
  • Clean the surface by manual & mechanical means, remove all the loose material or previous work done, make it free from any type of contaminants like oil, sand, debris etc
  • Prime the surface with max. 20% water adding to Tru PU. Mix it till it becomes Homogeneous, then apply by brush or roller to the surface. The coverage will be approx. 80-90 sq ft per Kg. The coverage will depend on the substrate condition
  • Tru PU should be applied direct by brush to obtain a continuous unbroken film
  • Two coats are required, second coat should be applied at right angles after the first coat has cured properly
  • It must be protected from mechanical damage during construction or backfilling works
  • Any damage may be repaired by spot application
  • If a water flood test is to be run, the membrane should cure for a minimum of 10 days
  • Tru PU is resistant to frost but adhesion will be weak if it is applied to frosted substrates/surfaces
  • Application should be avoided if substrate temperatures are below 5ºC or rain forecast. For any further technical information please contact the Astral Technical Services Department
