Fulacaulk FR is a one-part water based construction sealant for sealing joints in applications where a fire resistance rating is required. It has been tested in accordance with AS1530.4-2014
Do not apply to wet surfaces
Fulacaulk FR is not suitable for use in water retaining structures or where pooling of water may occur.
Fulacaulk FR is not recommended in external applications or where 2 non-porous substrates are to be sealed.
In many regions applicators of fire rated sealants require certification or licenses- check local regulations to ensure compliance.
Sealing interior construction joints that are subject to movement (up to ±20%) in concrete and plasterboard wall systems.
If joint movement is not required Fulacaulk FR can be used as a putty for filling holes in fire rated substrates
Apply Fulacaulk FR in ambient conditions between 5°C and 35°C. Higher temperatures should be avoided to prevent the possibility of bubbling of the sealant due to rapid moisture evaporation. Do not apply below 5°C. Fill joint using trowel or caulking gun then tool off with a spatula. Clean off excess product with a damp cloth.
Protect from water for at least 24 hours until a suitable skin has formed (will require significantly longer at temperatures lower than 15°C). Some shrinkage is normal during curing and should be anticipated when measuring joints.
