Application Procedure

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

Application Method

BROOT 120 is a ready to use material, it does not require heating or thinning. It is applied only to the side contacting with water (positive insulation). It can be applied with a brush, roller or airless pump at least 3 layes. 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. Although BROOT 120 dries as fast as in approximately 2 hours, it is recommended to wait for a day before the application of the next coat. To ensure perfect durability against higher pressure, it must be reinforced by bearing materials such as glass fabric, felt, and insulation fabric.


0,600 g/m² for each layer. Recommended at least 3 layers application.
