SCHOUBIT 2K is a two component, bitumen-rubber based and reinforced with fiber and elastomeric resins, elastic and quick dry liquid membrane. By evaporation of water it contains, it adheres firmly to the applied surface and forms 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 remove loose pieces. Sharp tips and horizontal/vertical joints which are suitable cracking should be chamfered with PH 55 or REPAMERK 1. Big pores and cracks should be filled with REPAMERK 301 repair mortar. To ensure strong adherence, avoid dust, and improve durability, non-metallic surfaces must be undercoated with B PR 101, and metallic surfaces must be undercoated with B PR 102.
SCHOUBIT 2K is cold applicable. Powder B component in the bag is poured into liquid A component under low speed mixer, they are mixed together until there remains no lump, getting homogenous mixture. After they are mixed, it is applied with a bitumen brush or trowel. Depending on the weather conditions, it dries approximately in 1 - 2 hours. It can be applied on damp surfaces, but not on wet surfaces. It should not be applied under the rain or when the temperature lower than +5°C. Next layer should be applied when the previous layer completely dry.
