Description

About Intumescent Acrylic Mastic (White)

Available in white, grey and brown. Supplied in 310ml tubes.

After application, a surface skin forms allowing painting, but stays permanently flexible.

It is a low-pressure material with good cooling ability for metals, expands up to five times its size in a fire. The white or grey mastic will glow in the dark or in a smoke filled room.

Ideal for use for filling small holes or cracks and as a seal between door frames and walls, around edges of partitions, or in voids around services such as pipes and cables.

It can be used in conjunction with Envirograf Intumescent Slabs (Products 4 and 5), Blocks (Products 2 and 3) and Expansion Joints (Products 39 and 40) to provide a robust penetration seal.

Application

A minimum of 12mm depth is required around ceiling, floor and wall joints in computer areas.

All surfaces should be sound and clean.

Oily surfaces should be wiped with white spirit and then dried.
Dry, dusty brickwork must be moistened prior to application of Intumescent Mastic, using a normal skeleton gun.

Extrude the mastic firmly against the sides of the joint, ensuring firm contact.

It can be painted once a surface skin has formed.
