Thermoguard Asbestos Encapsulating Coating

Thermoguard Asbestos Encapsulating Smoke & Flame Retardant Coat seals rigid, sound asbestos in locations within buildings which are not subject to mechanical damage, concealed or are difficult to access.

Also used to seal in isolated asbestos fibres remaining after primary asbestos removal has taken place. Effectively prevents the release of asbestos fibres into the atmosphere by encapsulating them. Permanently bonds residual asbestos fibres, after primary removal, to the surface to which they are attached or upon which they lay.

This product is available in 12m² or 50m² pack sizes. These tins allow sufficient product to apply the required 2 coats to the stated areas.

So, a 12m² pack should be used to apply 2 coats to 12m² and a 50m² pack should be used to apply 2 coats to 50m².

See further application and spreading rate details below.

questions Brian Gill on 2019-09-11 09:39:30

How long does it take to dry before appling the second coat?


Approximately 6 hours in good drying conditions.

questions Karen Grainger on 2019-06-19 08:44:29

Can this be used in an airing cupboard approx 3m x 1m ??


This coating is designed to encapsulate asbestos, if you have asbestos in a airing cupboard we would suggest you seek advice from your local authority on the matter promptly.

questions Tom Fyffe on 2019-04-10 07:25:52

hi, can this product be used to coat the inside of a garage that has asbestos sheets as a roof. The sheets are in decent condition and show no signs of leaking. If it is not suitable, do you sell a product that would do the job? Regrads Tom Fyffe


Where practical, surfaces should be clean and dry prior to applying 2 coats of Thermoguard Asbestos Encapsulating Coating. The 1st coat should be diluted 10% with clean water followed by an undiluted coat to create a continuous film.

questions Robert on 2019-01-08 09:01:03

Could I paint the inside of a garage roof it’s starting to seap through after heavy rain... the roof is pitched and I’d rather paint from inside than outside


Thermoguard Asbestos Encapsulating Coating in this particular instance would not be suitable to use on the underside of your roof to try and waterproof it. This should really be done from the topside with a waterproof roof coating such as Britannia Aquashield High Build.

questions Ian lee on 2017-08-02 21:20:28
Question: Can you use this on top of glasbesto cladding which is in sound condition will this paint Stick to the glasbesto cladding without rubbing down we are only allowed to clean surface with a water-based degreaser .

We are not familiar with 'Glasbesto', but if it is similar to rigid asbestos sheets - a dull granular surface - and does not contain wax or silicones, Thermoguard Asbestos Encapsulating Coating will bond extremely well without abrasion. 

Bond and every other characteristic are far better than vinyl emulsion, so a test patch to see if vinyl emulsion bonds will indicate if Thermoguard Asbestos Encapsulating Coating will bond well. 

Suitable for internal or external use but NOT on tops of roofs. 

questions Chris Wilson on 2017-07-12 23:00:22
Question: Could you please advise me who makes this product? Also, I need to coat a big area of asbestos soffit boards, which have already been painted. Can this be applied directly to the painted area, without the need to scrape any loose paint off? The soffit boards are made of a low grade of asbestos cement. Kind regards Chris

The manufacturer of the Asbestos Encapsulating Coating is Thermoguard. The coating can be applied over previously painted substrates but if the existing paint is glossy then you would need to create a key before application. If there are any areas of loose or flaking existing coating then these would need to be removed but care must be taken when doing so as you are working with asbestos. The coating can be used internally and externally with the only exception that it can’t be used on a roof.
