Are you ready to upgrade your walls and ceilings? Or are you starting a new job completely? Either way, it’s time to think about fire safety. If you are undertaking a project that involves communal areas, there are certain regulations you need to adhere to, to ensure fire safety. Learn how important it is that you protect yourself as well as any visitors, residents or employees, with fire protection at Rawlins Paints.
In order to satisfy building regulations, you must take certain measures to subdue the spread of fire to other parts of the building. This also includes any adjoining buildings. In a building such as a block of flats, it’s important to keep fire contained as the damage can be incredibly severe.
As well as using methods such as installing fire doors, you can look to the paints and coatings you are using on your walls and ceilings. This is one more step towards fire safety and combined with other preventative methods, can help you to meet building regulations for your property.
British Standard Class 0 & Class 1
These two classifications you may have seen on the tins of various paints and coatings. One is part of a classification system which can be found in Fire Safety, Approved Document B. This document contains many other regulations, so be sure that you meet all regulations, not just your walls and ceilings. The other is a test classification found in BS476, part 7.
Explaining Class 1
To achieve Class 1 on your walls and ceilings, you must use a paint or coating that is designed to prevent the spread of flames on the surface. Class 1 is actually a test, which looks at the distance and time it takes for flames to spread across a surface. Therefore, you could achieve a Class 4 finish, which would be the lowest and least desirable classification. To achieve Class 1, you need a protective paint or coating which allows the least spread of fire in the shortest amount of time.
Explaining Class 0
Class 0 can be found in Approved Document B. This classification means you must first achieve a Class 1 finish on your walls and ceilings, as well as the appropriate results on a fire propagation test. A fire propagation test is used to test the level of heat given off a surface during a fire. This is to make sure the amount of heat given off during a fire is substantially reduced by a paint or coating.
Meeting classification
By using a system with a fire retardant coating and a flame retardant topcoat, you can achieve both classifications. Your Building Regulations Officer can help you to understand if you need to achieve a Class 0 or 1 finish, or both. Remember, this is only a step in meeting fire regulations, but not one that should be missed.

Hi i have just fitted a mf ceiling with 2no layers of 15mm fireline board under a mezzanine floor
but i need to fire rated to a 2hr rating
please advise what paint
Good morning Mark,
The maximum you can achieve with a paint in this situation is 1hr.
Thermoguard would agree to certify 60 minute fire resistance to a ceiling (for example, with two layers of 12.5mm plasterboard, staggered and taped joints fixed to MF ceiling) on the basis of their bespoke specification (which can be obtained by emailing us). The specification also gives Class O and new Class B s1 dO (data sheet is available too by email which explains Class O + new Class B).
• Apply 1 spray applied coat of Thermoguard Wallcoat @ 2.8m² per kg OR 2 brush/roller coats @ 5.6m² per kg/per coat
• Followed by 1 coat of Thermoguard Wallcoat Smoke & Flame Retardant Topcoat Matt or Eggshell (any RAL or BS colour)
Fire Certificate FoC will be available after application.
Please contact us if you have any further questions, but 2hr fire rating will not be available for this.
Best regards.
Mark
Hi Mark,
We have a 1no layer fire line plasterboard the ceiling at the moment. What would be your suggestion to achieve class 1 in this situation.
thanks
H
Thanks for your question, H!
To achieve BS Class 1/0 & EN Class B on plasterboard apply 1 coat of Thermoguard Wallcoat followed by 1 coat of Thermoguard Wallcoat Smoke & Flame Retardant Topcoat in the colour and finish of your choice.
Best regards.
Mark
i need to convince a local authority to use a class b fire and smoke retardant (thermagard ) and not a class 0 paint specification could you explain the difference please.
Hello Dominic,
The new fire standard BS EN test lasts 20mins with airflow and replaces the old BS 476 tests which lasted for 10mins and with restricted airflow. The new standard for flamespread and heat release which is Euro Class B, replaces UK Class 0. The new BS EN tests also monitor smoke production, toxic fumes/gas release levels as well as flaming droplets.
Hi, If i paint my doors etc with thermoguard timbercoat (i am assuming it is like a topcoat of paint) how do i demonstrate to the LA that i have complied with building regs, do i just retain the tin and receipt?
Hi Rue,
To upgrade suitable, existing doors we would recommend Thermoguard Timbercoat Door Upgrade System. The doors must meet the minimum criteria to be suitable for upgrading and a certificate of supply can be provided following purchase and application.
Hope that helps, certainly let us know if we can be of more help.
Hi,
I have to find a treatment to apply to wood cladding (exterior walls of a garden room). The wood cladding is 18mm thick Thermowood. I have been told that it is not possible to obtain the required level of protection ( Class B-s3, d2(2) or better and be tested to BS 8414) on Thermowood. Could you please advise if that is true?
Many, many thanks in advance.
Hi Wendy,
Thank you very much for for your question. It is possible to achieve Euro Class B-s2-d0 on Thermowood using Zeroflame Fire Retardant Treatment providing this can be applied to bare Thermowood that has had no form of stain, varnish or paint applied beforehand.
I hope this helps, and please feel free to get in touch if you have any further questions.
Many thanks
Stuart
How can i convince Building Control in NI that this is suffice to provide adequate protection – can you provide specifics against the timber ceiling specifications?
Good afternoon,
Thank you very much for your question. In this instance we would advise contacting the manufacturer for assistance. We would recommend speaking to Thermoguard in this case.
I hope this helps, and please feel free to get in touch if you have any further questions.
Many thanks
Stuart
Do I need to finish with fire retardant paint to 60 min plasterboard partition and LDF skirting to escape route in non-domestic building to satisfy the requirement Class B-s3, d2 surface spread of flame ?
Thanks in advance
Hi Claire,
Thank you for taking the time to read our blog and for your question. Our Technical Department have advised that 60 minutes would be a higher/different level of fire protection.
The Thermoguard Wallcoat BS Class 1/0 & EN Class B System should be sufficient subject to approval from building control.
I hope this helps and please feel free to get in touch if you have any further questions.
Many thanks
Stuart

Hi there, Iv been converting an old property in to flats and only used 1 layer of fire rated plasterboard as overboard laf plaster but now the LA are saying I need to proof the fire rating of the laf plaster which will be a nightmare. Can you advise if I use your paint system that you will issue certificate.
Thanks
Hi Ben,
Thank you very much for taking the time to read our blog and for your question. Unfortunately we don’t currently offer a solution for lath & plastered surfaces.
We may be able to offer a system for the plasterboard that is overboarding the L&P. Please feel free to get in touch via our Contact Us page and our Technical Team will be happy to help and advise.
I hope this helps and please feel free to get in touch if you have any further questions.
