FAS Fire Door Intumescent Acrylic Sealant – White | Fire & Acoustic Rated – 310ml – Box of 24

This Fire Door Intumescent Acrylic Sealant – White helps stop the spread of fire and smoke. It is halogen-free and designed to expand when exposed to heat over 125°C. This forms a heat-resistant char that seals gaps and slows fire movement.

It provides up to 120 minutes of fire resistance, tested to BS EN 1634-1 and BS 476 Part 20/22. It is also Certifire Approved (CF5840), so you can trust its quality.

Use it around fire doors, cladding, walls, and service gaps. It’s easy to apply and stays flexible by up to 12.5%, even after curing. This makes it perfect for areas with slight movement.

Plus, it can be painted with most types of paint, so it blends in easily. The sealant is also acoustic, helping reduce sound as well as fire risk.

Because it bonds to many surfaces, it’s great for both home and commercial projects. Over time, it won’t crack, harden, or shrink — giving you long-lasting protection.
