Description

Formulated to provide a permanent, flexible joint between door frames, edges of partitions and walls, Envirograf Intumescent Mastic protects against fire, smoke and toxic fumes. Once dry, the mastic can be over-painted.

Supplied in a standard mastic tube, fitting any normal skeleton gun, in white, grey, brown and black colours.

An aqueous acrylic polymer emulsion, plasticisers, inorganic extenders, reinforcing fillers, surfactants and fungicide.

Application

For use as a seal between door frames and walls, around edges of partitions.

A minimum of 12mm depth is required around ceiling, floor and wall joints in computer areas. This prevents Halon gas escaping.

Around RSJ and wall cement joints, Envirograf Intumescent Mastic can be used in conjunction with Envirograf Intumescent Slabs, Block, Expansion Joint and Type E joint. Type E is an easy sponge type seal for large gaps that can be faced with Mastic.

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 Envirograf Intumescent Mastic, using a normal skeleton gun. Extrude the mastic firmly against the sides of the joint, ensuring firm contact. Overpainting can be carried out after surface skin has formed.

Maximum Joint: 60mm.

For gaps over 60mm, fit Envirograf Intumescent Coated Fireproof Sponge (Product 40) first.

Touch dry in approximately 15 minutes on surface

Clean tools with warm water after use.
