Sealmaster Intumescent Plaster


DESCRIPTION

Sealmaster Intumescent Plaster is a chemically modified surface coating and space filler. Small gaps, cracks, crevices and fissures often cause weakness in a building. If they occur where fire resistance is specified - in areas around fire doors or where service pipes and cables pass through a wall or floor, for example Sealmaster Intumescent Plaster should be used to make good the weakness. Under normal conditions, the plaster performs the conventional cosmetic and draughtproofing role of space filling compounds. Under intense heat, however, the plaster carbonises and its intumescent action swells to impede the passage of flame and smoke.

use
Intumescent Plaster provides a hard, durable fire resistant barrier between masonry construction and wooden frames. It can be used:

To fill over-large lock or latch recesses in wooden doors to prevent premature charring and failure in a fire;
To fill holes and gaps around ducts, pipes and cables where Sealmaster Intumescent Compound may not be applicable;
As a dry filler to plug holes drilled in wooden doors for cables etc. (for example: ventilator cables), and used wet to cap the hole.

application
Equal quantities of each of the two parts of the plaster should be mixed together thoroughly, and then water added and stirred to the desired consistency. The plaster should be applied like a conventional plaster with atrowel. When set, the plaster can be over painted.

availability
This product is available ex-stock with delivery normally within 7 - 10 days. Express overnight delivery can be arranged on request.
