Application Procedure

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 PH 55 or REPAMERK 1. Big pores and cracks should be filled with REPAMERK 301 repair mortar.

Application Method

B PR 101 should be applied as cold. It should be diluted with 20% water then applied with bitumen brush or airless gun. It dries within 4-5 hours depending on the weather conditions. It should not be applied in rainy days or within the temperatures lower than +5 °C. Second layer must be applied after first layer completely dry. For the applications that required higher durability against water pressure or on cracked surface, it must be reinforced with fiber glass, polyester felt, reinforcing fabric etc. The screed material that obtained by mixing B PR 101 with sieved fine sand and cement is applied with a trowel to smooth out and level the surface, or to provide a protective coat over insulation.
