We offer UK-wide specialist protection of building structures from the effects of fire. Our intumescent coating service can be applied on-site or off-site, to steel, timber or cement structural supports, giving protection from fire for up to 240 minutes.

Intumescent Coatings is a spray finish which insulates structural parts of the building from heat damage in the event of a fire for up to 240 minutes helping to ensure they are compliant with the latest building regulations. 

At CJ Paint Spraying we are an accredited on-site spraying company that works nationwide from our regional bases in London, Manchester, Liverpool, Birmingham, and Portsmouth.

Intumescent Coatings expands their thickness to up to 100 times when exposed to heat, and can be applied to structural steelwork, timber and concrete on-site, or off-site. Coatings can achieve heat protection of 30, 60, 120, 180 and 240 minutes, depending on the level of fire protection required by the client.

Intumescent Coatings are available in Water-based, Solvent-based, and Epoxy-based options:

Water-based Intumescent Coatings are generally more environmentally friendly and with less odour. These are the most cost-effective solution but are less tolerant to humidity and may take longer to cure in these environments.

Solvent-based Intumescent Coatings are used in semi-exposed environments and are suitable for all weather and atmospheric temperature variations. They dry faster than Water-based Intumescent Coatings and have a smoother finish.

Epoxy-based intumescent Coatings are suitable for use in harsh environments, such as offshore marine industries and petroleum-chemical industries. Epoxy-based coatings come in two parts which forms a very thick film, highly resistant to corrosion.
