questions simon gleave on 17/11/2018

can you have a top coat fire retardant paint for steel colored ral 7001 silver grey?


Yes, for example you could apply Bollom Brosteel Ultra 60, followed by any of the Bollom Flameguard Ultra Topcoats in RAL 7001 Silver Grey.

questions Andy on 13/09/2018

We're having trouble spraying this product it seems to be really solid in the bucket, any ideas.?


The manufacturer advises mixing the paint before use using a plasters whisk attachment on a drill. This should break down the coating and allow it to be applied by a suitable heavy duty airless spray unit. See under Application Methods on the Technical Data Sheet available to download from the Download section on the product page.

questions Pauline Harris (Polly) on 29/06/2018

Hi. I need intumescent white paint to cover a steel post of.....88.9x4 CHS to 60 min coverage. I will require a certificate for Building Control on completion. I like the look of the one you talk about on your website as only needs two coats to get it to required 60 mins. Also water based and east to apply. Many thanks Kindest regards Polly


Bollom Brosteel Ultra 60 would not be able to achieve 60min protection on this steel size due to the wall thickness being too thin. If you contact our Technical Department directly on 0113 2455450 or [email protected] they will be able to take some more information and advise a suitable intumescent for you.

questions John Soutar  on 26/03/2018

Neither, but it has succesfully been tested by Certifire who are an independent third party certification scheme that assures performance, quality, reliability and traceability of fire protection products. They are recognised by regulatory authorities worldwide, and is an internationally respected mark of fire safety and one of the most authoritative in the industry.

questions Rob Boteler on 01/06/2015

Will Bollom Brosteel Ultra 60 meet UK building regulations (Part B: Fire Safety) in the UK if we want to expose steel beams in our living room?


Bollom Brosteel Ultra 60 will provide 30 or 60 minute protection to structural steelwork. It is important that you check with your authority what level of fire protection is required for the steel on your project but usually for residential properties it will be 30 minute protection that is required. You can apply Bollom Brosteel Ultra 60 and then request a Certificate of Conformance and Installation from ourselves to provide to your authority as proof of completion.
