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.

I have a section of an asbestos pitched roof that has become porous in winter, what products would best seal it?

Answer from Rawlins’ Technical Team: 

This product can be applied to the applied to the underside of asbestos roof panels for the purpose of encapsulation. 

For application to the external face of the roof to seal it we would recommend Teamac Acrylic Roof Coating.

This is available in a range of colours in a matt finish.

questions Harvey Hintergardt on 2023-05-16 04:34:49

can you recommend a product that will encapsulate asbestos floor tiles. Also the mastic once the tiles are removed. Are there any that are non-toxic and have no VOC's. I have both conditions.

Answer from Rawlins’ Technical Team: 

Unfortunately we do not have a product to recommend for this application.

questions Alexander mcqueenie on 2023-04-15 23:10:23

Can this be painted over with another paint once it has dried.

Answer from Rawlins’ Technical Team: 

Yes this can be overpainted after application with an acrylic matt or acrylic eggshell water based paints if the paint is being used for asbestos encapsulation only.

To retain the Class B level of fire protection it can only be over painted with the Thermoguard Wallcoat Smoke & Flame Retardant Topcoat.

questions Ian Bradley  on 2023-02-15 15:55:10

What is the lifespan of coating once been applied to asbestos, walls or ceiling ??

The manufacturer does not state a lifespan for the coating, it should be regularly inspected for any damage and maintained.

questions David Golland on 2021-12-19 17:45:10

Can Thermoguard be used to seal smoke damaged asbestos sheets inside a building? Will it stop the smoke bleeding through?

Answer from Rawlins’ Technical Team: 

No this product will not stop smoke stains bleeding through.

Assuming the asbestos sheets are clean, dry, sound and prepared as detailed in the technical data sheet we can recommmend Zinsser AllCoat Interior (Solvent-Based).

This can be mixed to many RAL and BS colours in a matt finish.

questions Lee Williams on 2021-11-11 11:41:21

Hi, can this product be used in basements where damp is a problem. If not do you do a product that will seal asbestos fibers in damp conditions.

Answer from Rawlins’ Technical Team: 

Thank you for the enquiry, please can you provide more information and pictures for the asbestos areas you wish to encapsulate to [email protected] and we can check if this is suitable for your application.

questions David on 2021-04-14 16:45:23

Is it washable? Need to seal the underside of asbestos cement lining panels in a warehouse to be used for food preparation so surface needs to be capable of being washed.

Answer from Rawlins’ Technical Team: 

Assuming the asbestos is clean, dry, sound and prepared as detailed in the Technical Data Sheet it would be suitable for this application but only in the eggshell finish option.

Once applied and cured it is capable of being washed with warm water and standard detergents.

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

Answer from Rawlins’ Technical Team: 

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

Answer from Rawlins’ Technical Team: 

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 .
Answer from Rawlins’ Technical Team: 

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
Answer from Rawlins’ Technical Team: 

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.
