Efficient off-site spraying at the Woolston workshop
You can avoid on-site delays and bad weather by using the specialised workshop in Woolston. This is perfect for smaller jobs, timber cladding, slats, or louvres.

Intumescent paint for wood is a specialised fire-retardant coating that reacts when it gets hot. The paint quickly grows into a thick, protective layer of carbon foam (char). This char layer insulates the wood underneath, slowing down the fire, stopping the flames from spreading, and keeping the building stable so people have time to get out safely.
Milkiness or cloudiness happens if moisture gets trapped under the paint, or if it is put on wrong by inexperienced painters. We prevent this by testing the moisture levels in the wood and spraying in the right weather conditions. This guarantees your clear finish stays perfectly see-through.
Yes. For smaller jobs, timber slats, or outdoor cladding, parts can be painted off-site at the Straightcut Intumescent workshop in Woolston. This indoor space ensures the paint goes on at the perfect thickness and dries properly. Your materials arrive on-site fully certified and ready to install.
