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

Can you paint a colour over the fireproof paint?
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.
