Description

Intumescent Paint for Wood

A range of clear and white intumescent fire-resistant paint for wood. Giving protection to various wood and wood-derived materials. It is ideal for painting or upgrading existing wood or timber surfaces to either 30 or 60 minutes of fire protection. This paint is especially suitable for use on insulation board, MDF board, plasterboard, wood, and some wood-derived products. There is no need to strip off the existing paint or varnish as Envirograf adhesion primer is also available. See our references tab for full details of products in this range. Paint application using a brush, roller, or spray. Additionally, this range provides UV protection for external timber surfaces.

All types of new and old doors, some over 200 years old have undergone testing. All tested in accordance with BS476 part 22 (1987) and their fire resistance was upgraded to an integrity of over 60 minutes. The HW range can also upgrade wood panelling to 30 minutes or 60 minutes fire rating, according to the type of wood and its thickness. Open joists and floorboards have achieved 60 minutes of fire protection on a loaded floor to BS476 Part 20 (1987). Timber mouldings and carcasses have achieved 90 minutes of fire rating to BS476 Part 20 (1987). A range of timber types, including MDF and plywood underwent testing and complied with BS476 parts 6 and 7 (1987) Classes 0 and 1.

We provide an extensive range of fireproof coatings, intumescent paint, wallpaper, and sprays compatible with a range of materials. Explore our Fireproof Coatings online.
