Class B Application

This 2-pack PU acrylic system is easy to apply with any type of spray equipment. It provides good flow and excellent film clarity, can be colour-matched to pretty much any colour and has excellent anti-yellowing properties. EF1 also has good resistance to abrasion and scratching and meets FIRA 6250 Severe Use rating.

The coating system is straightforward.

1) To upgrade standard timber to Euro Class B-s1d0, apply two layers of basecoat followed by a clear or coloured topcoat.

2) Basecoats can be thinned by up to 10% using Euro-Fire EFT thinner, and the topcoat can be applied to the correct thickness in thin layers.

3) If you're working with timber in atmospheric conditions, exotic timbers or pre-treated fumed timber, use an isolator coating before applying the basecoat.

This improves adhesion and stops the wood from having a milky-looking finish. So, for example, you would need an isolator coating in a hotel with a timber-clad spa as it would be subject to moisture and humidity.

Maintenance Of The System

1)Maintaining cladding to Euro Class B fire retardancy is easy. Just apply one basecoat layer and one topcoat layer.

Remember: Fire protection coatings only work when applied to the correct thickness. Isolators, basecoats, and topcoats have different coverage requirements to be compliant, so always double-check the technical datasheet before using a product.

PLEASE NOTE : EuroFire Base Coat must be overcoated with EuroFire Topcoat to comply with BS 476 Part 6 Class 0 rating.

ISF EurofireFRIntumescent System has been tested by The Warrington Research Association to Class 0 rating to BS 476 Part 6 Ref WF163144 (March 2007) & also BS 476 Part 7 Ref 182676 (September 2010).

Why Has The Fire Classification System Changed For Wood?

In the wake of the Grenfell Tragedy the givernment has firmed up its classfications formerly known as Class 0 to include further controls for the fire safety and ignition of timbers in buildings.

If you are installing, spraying or modofying timbers in any residential or commercial setting you'll now need to ensure your paint system complies to Part B of the Building regulations and Fire Regulations code.

Class O Old And Class B New - What's The Difference?

The new Class B system is a beefed up version of Class 0 with a major difference. Class 0 was a standalone rating where a classification was given such as NA, 1-4 or Unclassified. The new Class B follows the Euro system and takes into account 2 overlapping ratings.

Firstly you have letters A-F which correspond to the old class system so a Euro B is the old Class 0 (see table below). However to further bolster the safety of the rating there is an overlapping rating that meets with the letter classficiation. So a product may now be a Euro B s2 d0. The Euro B is the new Class 0 standard and the S stands for level 2 for Smoke Development while the d0 is the realtive droplets falling from the flame.

s2 is the amount of smoke generated, 1 would be best, 3 the worst

d0 is the relative amount of flaming particles falling , 0 is best, 2 the worst

(see the table below for best to worst ratings for the additional tests.

Old Class Standard Vs New Euro Standard

Additional Ratings For Smoke And Droplets

Products with a European rating have other lower case letters and numbers written after the letter – Do they mean anything?

Yes they do. Let’s say you have C-s2,d0

C is the resistance to fire (as shown in the earlier chart)

s2 is the amount of smoke generated, 1 would be best, 3 the worst

d0 is the relative amount of flaming particles falling , 0 is best, 2 the worst

I'm A Joinery Sprayer What Classification Should I Adhere To?

If you are spraying timbers you need to know not only the classification but also what classification to stick to for each job you take on!

OK, so what do Building Regulations say I need?

That depends on where exactly you will use the wallcovering. The chart included here shows how different rated wallcoverings can be used in projects subject to Building Regulations:
