Product Description

This Envirograf system offers a white or coloured solution to upgrade solid wood/timber doors to up to 30 minute fire resistance (subject to suitability) by using Envirograf intumescent coatings. These packs have been created to help users ensure they are purchasing sufficient materials for their project. Each pack contains the correct amount of Primer (Envirograf HWAP/WB Primer), Intumescent (Envirograf HW01 White Intumescent Coating) and Undercoat (Envirograf HW04/S Undercoat) to ensure protection is achieved inline with the manufacturers recommendations to the respective area in question.

These packs offer the Envirograf paint system ONLY, if you require intumescent card, mastic, hardware, etc. for your doors please contact the Technical Department. This system offers a clear primer, white intumescent and white undercoat sufficient for 4m², 10m² or 20m² of door surfaces. Fire and smoke seals should also be fitted to each door upgraded. Remember, intumescent paint is just one element of protection and DOES NOT create a ‘fire door’. Intumescent materials and hardware MUST be used to ensure your doors meet the required standards of your authority. 

If you are looking for a clear finish, we also stock our Fire Door Varnish.

For doors requiring 60 minute fire resistance please contact the Technical Department on 0113 2455450 or [email protected]

Question: What is the minimum door thickness to schieve fd30 with your kit?

Please download and read 'Door Upgrading Technical Data' from HERE.

questions Esther Grossmann on 24/04/2017
Question: In order to apply the fire retardant coating does the previous layer of paint on the door need to be removed or can the existing door be painted over by your product followed by new paint?
thanks for letting me know
Kind regards

No any existing paint does not need to be removed as long as it is sound, well adhering and not fire retardant. The substrate surface must be clean of all dust and dry. There should be no trace of oil, grease or similar substance. The surface should be sanded smooth. If timber is previously painted, ensure the surface is clean and sanded appropriately to provide adequate key.

Question: I have been asked to paint 16 previously painted fire doors on one side (hall side). Which paint system should I use and how much do I need.
There is no info on regulations etc

To protect 16 door sides to 30min fire resistance you would require 4 of our Fire Door Paint (30min) packs. Download our 'Fire Door Systems Brochure' from the 'DATASHEETS' tab on the product page to check your doors are suitable and seek approval from your authority for this system prior to purchase and application.

Finally, you may want to check with your authority which side of your doors need protecting with our product as usually the 'risk' side would be the room side of each door, NOT the 'hall side'.

Question: I'm interested in your door upgrade pack and note that the sealer coat can be over painted with a solvent based normal paint. We will be using a water based paint for the woodwork. Would you advise leaving the door with the sealer coat as the finish layer. (All subject to BC approval). Thanks

The Fire Door Paint (30min) system is completed by the application of a white undercoat (included in the pack). This MUST be over painted and cannot be left as a finish. Conventional, single pack, decorative Water or Solvent based paints are acceptable to overcoat the undercoat to provide the colour and finish you require.

questions Mark Howard on 08/11/2016

One of our clients has considered using intumescent paint to upgrade ordinary office doors and the painter has told them they "only need doing on one side". Reading your guidance confirms that you recommend painting the "risk side" by which I presume you mean the side the fire is likely to be on? However for doors opening onto a stairwell either side could have a fire and therefore both sides should be treated with intumescent paint. Could you confirm this? As a principle though upgrading the doors is a good idea so subject to your confirmation of the instructions I would probably recommend to them to proceed.


One of the advantages of our Fire Door Paint (30min) and Fire Door Varnish (30min) systems is that where deemed appropriate by the authority it can only be applied to the risk side of the door and still certified. That said, we do state in our product information (Fire Door Systems Brochure) that the user should seek guidance from their respective authority to ascertain which doors need to be protected in their property and on which sides. If you have deemed that your clients doors require protection on both sides then both sides should have the Fire Door Paint (30min ) system applied to them including any architraves, frames, etc. where required. This is why we sell the product by door sides rather than doors as a 4 door pack could upgrade 4 doors if only one side requires protection or 2 doors if both sides require protection. I trust this clears things up, should you have any further questions please do not hesitate to contact our Technical Team on 0113 2455450.

questions Helen Ward on 13/09/2016
Question: How long does this paint last?
Does a door that has been treated have to be repainted every few years?
How long can the paint be stored for once it has been opened?

Once our Fire Door Paint (30min) has been used on the door(s) then it will last as long as the substrate. We recommend a re-application of a topcoat every 5-7 years just to ensure no damage occurs to the intumescent system underneath. Any damages to the door should be repaired immediately with the full system to the affected area. Once the tins have been opened the shelf life reduces to 3 months.
