Water based intumescent coating for the protection of steel and aluminium. Has a smooth finish which can be easily painted over with any good quality paint for decorative purposes. Can be easily applied to surfaces by brush, roller or spray.
Unprotected steel can lead to building construction collapsing in a fire: It can take just a few minutes for unprotected steelwork in a building to attain temperatures of around 550ºC in a fire. At this temperature, steelwork loses its load bearing capacity and the structure is likely to collapse, giving little time for people to evacuate and even less time for the fire service to bring the fire under control.
Building regulations and legislation demand fire protection to upgrade the fire resistance of buildings and the Envirograf® range of intumescent coatings can certainly stand the heat. As modern design often involves steel being expressed as an architectural feature, intumescent coatings are frequently the protection of choice.
EP/FS/INT offers up to and including 90 minutes of fire protection and can be applied both on and off site.
EP/FS/INT is a waterborne product with low odour, often chosen as the ideal solution for on-site application. A full range of top sealers, both waterborne and solvent based are also available to complement the intumescent coating.
- Provides up to 90 minutes fire protection, dependant on the thickness of metal it is applied to
- Ideal for both internal and external protection of structural steel and aluminium
- Dries in approximately one hour under normal conditions
- Can be applied to untreated surfaces, or to previously coated surfaces with the use of our internal or external primers
We’ve tested our intumescent steel paint to address the popular question of the feasibility of painting the Product 83 over the existing coats of paint on top of the steelwork.
The test was carried out on two equal pieces of I-beam. Both specimens were coated with 8 coats of standard paint, after which, one of them was coated with Product 83 (Including EP/FS/60P Primer). The test lasted for 150 minutes.
After the test was stopped and the charred intumescent was brushed off, we discovered that the original coatings remained unscathed.
Since the date of this test, Product 83 has enjoyed great popularity among factories, public buildings and businesses alike by providing 2 hour fire protection without the need to remove the existing coating.
FIRE TEST PERFORMANCE
Tested to BS476 Part 20 (1987), showing that it can offer protection to structural steel for up to 90 minutes, and it has been tested when applied over multiple layers of existing paint, achieving protection of 150 minutes.
Tested to BS476 Part 22 (1987) on aluminium with Granada Windows, achieving 38 minutes of fire protection and again on aluminium with Wessex Medical lifts, achieving 49 minutes of fire protection.
Ensure that steel is cleaned and free from loose rust. Over existing paints, ensure that the surface is clean, dry, and free from grease or loose material before applying the primer. Slightly abrade any top coat to provide a key for the primer. Apply Envirograf® EP/FS/P primer at a rate of 8m² per kg. If a primer has already been applied and is sound, then there is no need to apply Envirograf® primer. Apply Envirograf® intumescent coat EP/FS/IN over the primed surface by brush, roller, or spray to give the correct loading as specified. Depending on the thickness of the coats applied and the air temperature and humidity, each coat will take approximately one to two hours to dry. Do not apply the Envirograf® intumescent coat EP/FS/IN externally if rain is imminent. The top coat must be applied for weather protection or the area should be temporarily covered over to prevent damage to coated areas by rain, snow, or water leakage. If a paint contract is not going to be completed in a day, it is advisable to concentrate on one area at a time, thus ensuring all the coats including a top coat can be applied in the same day. This does not apply to internal applications where rain, water, or moisture are not a problem. Where the steel is external, application of an undercoat is advisable. Use EP/FS/XP at the rate of 10m² per litre. Allow 4-6 hours for this coat to dry. For internal use apply the EP/FS/TCW top coat at a rate of 10 -12m² per litre. For external use apply the EP/FS/TCE top coat at a rate of 2 coats at 10 -12m² per litre. The top coats can be supplied in any RAL or BS colour.
