B PR 102 is a ready to use, rubber content, waterproofing bituminous solution without any filler. After evaporation of the solvents it contains, B PR 102 adheres firmly to the surface it is applied, forming an elastic waterproof layer.
Preparation of Substrate
Application surface must be dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and removed loose pieces. Sharp tips and horizontal/vertical joints which are suitable cracking should be chamfered with REPAMERK 1 or PH 55. Big pores and cracks should be filled with REPAMERK 301 repair mortar.
B PR 102 is applied only onto the side exposed to water (positive insulation). It is ready to use, it does not need heating or thinning. It can be applied by brush, roller or spray gun. B PR 101 is recommended as a primer for non-metal surfaces to provide excellent adhesion, avoid dust and improve durability. Although B PR 102 is a fast drying type of solution (2 hours approximately), it is recommended to wait 24 hours before applying a second coat. Reinforcing materials such as polyester felt, fibermesh, reinforcing fabric can be used to provide better durability against higher pressure. ALUCOAT should be applied as topcoat to obtain solar protection and aesthetic look on the roof which are continuously exposed to outdoor conditions and close the traffic.
