400 BT-2K

 Two component, bitumen extended polyurethane based, elastic cold applied liquid waterproofing membrane. It produces a highly elastic membrane with its excellent adhesion to many type of surfaces.

Features & Advantages

  • Simple application
  • When applied forms seamless membrane without joints
  • It has excellent elongation properties
  • It has root resistant and it is certified for root resistant
  • Resistant to slack water and frost
  • Its low modulus gives to it excellent substrate crack-bridging properties
  • High water vapor permeability
  • It provides permanent elasticity up the -40 ˚C to +90 ˚C
  • Resistance in the cold: The film remains elastic even down to -40 ˚C, • Resistant to chemicals
  • It is used as a joint sealant
  • Elastomeric hydrophobic based
  • Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance.

Typical Application

  • Non-potable water tanks
  • Basements
  • Foundations
  • Bridge platforms
  • Cut-and-cover tunnels
  • Bathroom, terraces and roofs (under tile waterproofing)
  • Concrete structures
  • Retaining walls
  • Gypsum and cement boards
  • Polyurethane insulation foams
  • Asphalt membranes
  • Green roofs and flower pots
  • Light roofing (metal and fibrous cement based)

Surface Preparation

All surfaces must be free of oil, grease and moisture before the application. Clean the surface using a high pressure washer and remove oil, grease and wax contaminants, cement laitance, loose particles and mould release agents must be removed. Fill surface irregularities with the relevant product.

PRIMING
Prime very absorbent and brittle concrete or brittle cement screed surfaces with PU PRIMER 200 or EPOXY PRIMER (Humidity of the concrete should not exceed %5). Or for damp concretes PU PRIMER 300-2K or EPOXY PRIMER WB is suggested as a moisture barrier. Prime non-absorbent surfaces like metal, ceramic tiles and old coatings with PU PRIMER 300-2K.

APPLICATION
Firstly mix the portions (A and B) separetly by a low speed mixer for a couple of minutes. Then mix the portions in same container. The pot life of the mixture is 30-35 minutes at +20 ˚C, pot life may change depending on temperature. Apply the mixture on primed surface with a brush or a roller in minimum two layers. Second layer should be applied in min. 12 hours max. 24 hours after application of first layer. If this time expired or layers are not adhered well, PRIMER 100 should be applied. For single thick coat, min consumption should be 1.50 – 2.00 lt/m2
