About this Product

The Intumescent & Acoustic Acrylic Sealant is a polymer emulsion based sealant that swells when subjected to temperatures in excess of 125 ̊C and forms a char coat that restricts the passage of smoke and fire. This sealant can be used in joints up to 35mm wide without slumping. It is ideal for sealing joints in and around internal partitions, lap joints in fire-rated cladding and for sealing between fire doors and fire-rated walls. 

Things we thought you should know!

It is recommended that a sealant depth of at least 8mm be applied.

If the sealant is to be overpainted, building regulations may require a fire-resistant coating.

This product is not suitable in joints where movement exceeds ± 12.5% of joint width, or in external joints.
