Envirograf Door Upgrade Paint System
This Envirograf system offers a white or coloured solution (you can apply your own decorative top coat to colour co-ordinate a property) to upgrade solid wood/timber doors to up to 30 minutes' 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 coatings/layers to ensure protection is achieved inline with the manufacturer's recommendations to the respective area in question:
- Primer (Envirograf HWAP/WB Primer)
- Intumescent (Envirograf HW01 White Intumescent Coating)
- Undercoat (Envirograf HW04/S Undercoat)
This system offers a clear primer, white intumescent and white undercoat sufficient for 4m², 10m² or 20m² of door surfaces. 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 and test results of the manufacturer.
For a comprehensive range of fire rated door seals, hinges, letter boxes, door viewers, glazing channels and more, see our Door Upgrade Products category.
If you are looking for a clear varnish instead for bare or previously stained/varnished doors, we also stock Envirograf Door Upgrade Varnish System.
For flat panelled doors that require intumescent card/veneer see: Envirograf Intumescent Material & Paneled Door Upgrade
NOTE: This system is only suitable for solid (NOT hollow core), well constructed, good condition doors and minimum measurements apply as per the manufacturer information and test data. A wide range of supporting documents can be found HERE and we recommend you seek approval from your authority prior to purchase and use.

Hi, I currently have some FD30 blank fire doors that I need to cut down to fit small doorways. Would it be suitable to do this and to then paint them with your paint to meet requirements? The only other option that I can see is custom made fire doors which gets expensive. I look forward to your response. Thanks!
Providing your doors are suitable and meet the minimum requirements then you can apply our Envirograf Door Upgrade Paint System and obtain a certificate from the manufacturer following purchase and application.

Hello, please can you advise if both sides of the door need to be coated if the door opens into the hallway/escape route. Also, just to reconfirm that it's definitely fine to use a standard wood paint on top to match rest of woodwork, skirtings etc after using this system? Thank you.
In general the manufacturers recommendation for this product is that doors only need to be coated on the room side (risk side) unless they are being used as a fire break within a corridor. However we do recommend you check with your authority what their requirements are for your project. Once the coatings have been applied you can go over with a topcoat of your choice, but we recommend carrying out a small test area first to ensure adhesion and compatibility.

I have used your water based system on 4 doors ; can I now put a gloss paint on to finish
Assuming you have correctly applied the Envirograf Door Upgrade Paint System (Envirograf HWAP/WB Primer, Envirograf HW01 White Intumescent Coating and Envirograf HW04/S Undercoat) to suitable timber doors, then yes you can go over with a standard, decorative topcoat of your choice. We would recommend you carry out a small test area first to ensure adhesion, compatibility, etc.

Question: What is the minimum door thickness to schieve fd30 with your kit?
Please download and read 'Door Upgrading Technical Data' from HERE.
|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 Esther
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'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.
