Fire Paint for Lath and Plaster

Fire-resistant aqueous paint for lath and plaster to upgrade the surface. A white, or coloured, fire-resistant intumescent coating system. Offers fire protection to plasterboard or lath-and-plaster ceilings and walls of various thicknesses.

Provides an excellent solution for projects where plasterboard needs fire rating but cannot be replaced.

Listed buildings benefit from the application of fireproof paint, which is an approved upgrading solution by Building Control. A suitable solution for protected and heritage buildings which do not currently meet fire standards.

When attacked by fire, the intumescent material protects the integrity as well as the insulation of the coated surface. Moreover, offers over 1-hour fire protection to plasterboard.

Works for concrete too!

EP/CP fire protection coating system is an extremely cost-effective way to offer up to 120 minutes fire protection on concrete in a three-coat application.  It is ideal for concrete structures such as car parks and particularly in high-risk flammable storage spaces.  EP/CP has been used on a number of high-profile projects including the Channel Tunnel, the new Rolls Royce building, and the Sun Alliance multi-storey car park.

Application Instructions

Clean all walls or ceilings, taking off any loose paint and removing all wall or ceiling paper. Any grooves or cracks in the ceiling or walls can be made good with Envirograf® Intumescent Cement – Product 63 or AM Intumescent Mastic – Product 58. Should it be found that EP/CP will not adhere to the existing coating, then either apply a PVA Adhesive Coating at a 50/50 ratio of adhesive to water, or apply 1 coat of Envirograf® EP/CP/P Adhesion Primer at 14 m² per litre. Then apply 2 coats of EP/CP at the rate of 8 m² per litre, per coat. The approximate drying time is 1 hour. EP/CP needs a Top Finish Coat. This can be any make of external Smooth Acrylic Emulsion or Envirograf® HW/AEC Acrylic Coating at 10 m² per litre, per coat. This can be coloured and is available in matt or satin.


For Wallpaper or lathe plaster this can be left but instead of 2 coats you must apply 3 coats at 8m² Per Litre Per Coat.


HW04/UC white spirit based Undercoat at 10 m² per litre.
HW04/TC white spirit based Top Coat at 10 m² per litre. Available in matt, satin or gloss.
EP/CP and all the Top Coats can be coloured.
EP/CP can be painted onto all cornices or plaster mouldings with the same Top Coats applied.

Where cornices have gold leaf on them, a clear coating HW02/E can be applied – 3 coats at 8 m² per litre, per coat. For the Top Coat, apply 1 coat of BL/TCW water based clear Top Coat at 8-10 m² per litre.
