About Acoustic Acrylic Sealant
Drywall Master FR Acrylic is a halogen free, polymer emulsion based sealant that swells when subjected to temperatures in excess of 125oC and forms a char coat that restricts the passage of smoke and fire. It is easily applied and dries to a flexible and smooth surfaced material which is readily over paintable. It has excellent adhesion to a wide range of substrates and will not harden or crack with age.
Applying Acoustic Acrylic Sealant
Drywall Master FR acrylic forms a fire and smoke seal 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. It is recommended that a sealant depth of at least 15mm be applied. If the sealant is to be overpainted, building regulations may require a fire resistant coating.
