questions Ian Blackwell on 21/01/2019
Question: 

Hi I have a basement kitchen in an HMO property. The ceiling is a mix of plasterboard and exposed wooden beams (the plasterboard inserted between beams). There is a requirement for 30 minute protection, and the beams were therefore treated with intumescant varnish some years ago. I now intend to paint entire ceiling (both plasterboard & beams) white, and want to make sure I use the correct intumescant paint to give the 30 minute protection. Any advice much appreciated, thank you.

Answer: 

To upgrade the plasterboard areas we would recommend you use Envirograf's EP/CP coating.

Specification is as follows:

Once this has been applied you can go over both the previously upgraded timber and the plasterboard with a finishing coat of Envirograf HW Acrylic Top Coat applied at 10m² per litre to provide the white finish you desire. This will provide the 30 minute rating required assuming the timber previously upgraded has been carried out correctly and is still intact/valid.

Hi please can you tell me if this paint can be used on varnished wood stairs?

Answer: 

If coating over existing paint or varnish apply Envirograf HWAP/WB Primer first. Please note that this coating system cannot be used on any areas of the stairs that are trafficked, i.e. stair treads, hand rails, etc.

We have a specification requiring a ceiling to be painted with intumescent paint to be 1 hour fire protection for the room above what would you recomend

If the ceiling in question is timber, we would require the following details to enable us to provide you with a specification and quotation;

  • Size of surface area to protect

  • Type of Timber surface (i.e. T&G, feather edge / shiplap cladding, solid panels / sheets, etc.)

Question: 

Hi I'm looking at updating my doors to 20 minute firedoors to comply with building regs for a loft conversion, Will the doors need to be stripped back to bare wood?,they are white gloss at the moment

Answer: 

Envirograf Door Upgrade Paint System Packs allow users to upgrade solid wood/timber doors to up to 30 mins' fire resistance. Existing paints do not need to be removed assuming they are not a previous fire protection coating and are sound and well adhered.

questions Elisabeth Moyes  on 09/09/2018
Question: 

Can you paint a colour over the fireproof paint?

Answer: 

Envirograf state that once Envirograf HW01 White Intumescent Coating has been applied you can go over with a topcoat of your choice. They do however recommend you carry out a small test area first to ensure adhesion and compatibility.
