questions Peter on 17/09/2018

I have had a log burner installed. What paint should I use around the log burner?


Please see our Blog post Painting the Walls around a Fireplace or Multi Fuel Stove for details regarding this type of application.

questions Paul Jepson  on 05/08/2018

Can I use your paint to coat the existing ceiling plaster work to the cellar steps as this would save fireboarding etc Hope you can help, Many thanks Paul Jepson


We wouldn't recommend Thermoguard Flame Retardant Topcoat for plasterboard/plastered surfaces. We can offer an alternative system if you can advise the level of fire protection required - i.e. Class 1, Class 0, 30min, 60min, etc?

questions Nigel Eustace on 05/05/2016
Question: Can I use your paint products to fireproof my ceiling as I have not used fire retardant plaster board to encase the new steel for my loft extension. I have to have it looked at by a building inspector.

You can use our products to achieve BS Class 1, Class 0, 30min or 60min protection on standard plaster walls and ceilings but the product you are currently looking at is not the one to do it. Please contact our Technical Team on 0113 2455450 to discuss your requirements and they will provide a specification and quotation accordingly.

questions Claire Pullen  on 31/01/2016

What paint should I use to paint an indoor brick fire wall?


We recommend using Thermoguard Wallcoat Smoke & Flame Retardant Topcoat. This product isn't heat resistant and may discolour over time if continually subjected to high temperatures, but it is a much safer alternative to standard emulsion.

questions C raw on 20/09/2015

Can I use Thermoguard Flame Retardant Eggshell directly onto wood or does it need primer?


Thermoguard Flame Retardant Eggshell can be applied directly to wood but if you require any level of fire protection then Thermoguard Timbercoat must be applied first in accordance with it's instructions.
