FIRE RESISTANT COATING FOR PLASTERBOARD, PLASTER AND LATH
DESCRIPTION
If your property has plasterboard walls or ceilings that need to conform to current fire rating standards, it is worth considering the use of a specialist intumescent coating. A fire resistant coating which forms a protective layer on combustion, keeps the integrity of plasterboard or lath and plaster. It can be applied to walls and ceilings of different thicknesses. This coating is particularly valuable for jobs such as historical properties where old plaster surfaces and features cannot be taken out due to listed building regulations. The intumescent material ensures that these kinds of areas stand up much longer in the case of a fire.

ADVANTAGES
- The intumescent coating can be used on plasterboard of 9 mm to 12 1/2 mm thickness and also to 18 mm or thicker lath and plaster and concrete ceilings and walls. This gives an hour of fire protection to the surface.
- The fireproof coating is also able to be used to protect and insulate concrete and steelwork within a layer of concrete.
- When it dries a decorated finish can be achieved – either stippled or smooth, depending on your preferences.
- When the fire rating of features in historical buildings need brining up to date with modern fire regulations, this coating is perfect as the existing plaster features do not need removing.
APPLICATION INSTRUCTIONS
Prior to applying all walls or ceilings must be methodically prepared. Loose paint and any wall or ceiling papers must be removed. Cracks and gaps in the surface should be made good with an appropriate intumescent cement product. If adhesion is likely to be problematic, a PVA adhesive coating at a 50-50 ratio of adhesive to water should be applied first. Following good preparation two coats of the intumescent material should be applied at the rate of 8 m² per litre for each coat. The coating is dry to a smooth finish in about one hour. Conversely, if you want a textured finish, then apply one coat at 8 m² per litre, and then one coat of a slightly thicker version of the coating that can be comb finished. A smooth acrylic emulsion can be used to apply a top finish coat at a rate of 10 m² per litre per coat. Mat or satin finishes can be attained.
A white spirit based topcoat can be applied at 10 m² per litre which can give a finish in either Matt, satin or gloss. All the top Coats can be coloured. This coating can also be applied to many types of cornices or plaster mouldings using the same top Coats as a finish. When you need to go over gold leaf, a clear coating can be applied using three coats 8 m² per litre per coat.
We can give your floors a coating of a special new compound that makes your floor fire retardant, improving the sustainability of your property and aiding escape for the occupants in case of a fire. Please call us for more information
In the advent of a fire the Imtumescent paint expands up to 50 times its thickness to form a char layer or insulating layer, the char keeps the steel structural integrity below critical temperature and therefore stabilises the steel structure of the building.
Low pressure intumescent resin: This product is suitable for use in passive fire protection in general, and in fire stopping and interior fireproofing in particular. This type of intumescent is typically highly endothermic and contains a considerable amount of chemically bound water in hydrates. As this is released, it cools adjacent materials. Such intumescents are useful as ingredients in firestop pillows and in paints used for fireproofing purposes.
