Intumescent coating applications for different substrates
- 10 Jan, 2023
What are the different substrates we operate on?
Our intumescent coating systems can be applied to steel, timber, concrete and lath and plaster and we can protect also plastic materials. There are different coating systems for different substrates and the methodology differs slightly for each coating system. Here are some below:
Used for Timber, wood and wood derived materials. Our HW system 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. It is a range of white and clear coatings, white being HW01 and clear being HW02, which is perfect for upgrading doors fire rated to 30 or 60 minutes and can upgrade wooden panelling. Our HW systems can be used internally and externally depending on which system you use. We also provide our own top coat for HW systems also to provide a clean, smooth finish.
Q/VFR & ES/VFR system
Q/VFR system is a two-coat system for which can be used internally only and is used on Timber, bamboo, chipboard, decorative laminates, furniture, plywood, MDF, melamine and other wood derived materials. Additionally, provides UV protection for external timber. This coating system comes in two colours either clear or coloured giving class 0 and class 1 EU SBI/B/s1/do. Also 20 minutes of fire protection.
ES/VFR System For Internal And External use
Fire retardant coating for timber for external or internal purpose. The ES/VFR system is a two-coat system that should have a top coat applied whether you use the white or clear system.
Fire-resistant aqueous paint for lath and plaster to upgrade the surface. A white, or coloured, fire-resistant Intumescent coating system, offering fire protection to plasterboard or lath-and-plaster ceilings and walls of various thicknesses. This coating system is a very effective passive fire protection method for when plaster board needs protected and the installation of fire stopping structures is not possible. Lots of listed buildings walls are built with plaster board, proving this coating system an asset for heritage building projects. You can see proof of this with our approved installer Flamma Ltd who completed a large project in a listed building in Dublin. Read about this here.
The EP/CP system involves a primer, EP/CP/P, so there is no need to strip any previously applied paint.
EP/CP can also be used on concrete by a 3 coat application, of primer, intumescent and top coat, you can refer to these coats on our website. This is a very cost effective form of passive fire protection on such projects such as underground car parks. Such projects have been undertaken on the channel tunnel and multi story car parks.
This coating system is used on steel and aluminium materials. This is a water based paint can be rolled, hand painted a sprayed and provides a smooth, clean finish. Passive fire protection on steel structures of buildings is crucial as without it, a building is susceptible to collapsing in the event of a fire as the temperature of steel can rise rapidly to temperatures of around 550 degrees celsius and melt, causing it to lose its capacity to hold structural integrity of the building. EP/FS/IN will offer up to 90 minutes fire protection for a building and is in accordance with the building regulations and registrations.
A white protective coating for PVC, glass fibre, and also UPVC. This coating forms a protective intumescent foam layer which will protect the material when exposed to fire or excessive heat. This coating can be used for electrical cables, cable housings and engine housings. Electrical fires are a massive risk to buildings as they re difficult to attack at the source and the signs can be odourless and invisible.
