Flamex One emulsion based sealant sets quickly and gives excellent adhesion to most building materials. It has a 10% movement accommodation factor for low movement joint sealing and gap filling applications such as fire door frames. Flamex One is also suitable for sealing around fire protection boards. It can be used in joints from 5 to 20 mm. The minimum depth of seal should be 15 mm. Acts as an acoustic sealant.

Flamex Two high performance sealant forms a tough, flexible rubber-like seal with a movement accommodation factor of 25% for high movement situations. Flamex Two is suitable for expansion joints in building superstructures and may be used in both internal and external joints. Flamex Two can be used in joints from 5 mm upto 50 mm wide. The width of sealant should ideally be twice the depth, with a minimum depth of 12mm. In trafficked joints, sealant depth should be a minimum of 20 mm. The use of a surface primer is always required.
