Thermocoat W is a low odour, water-based coating, making it user and environmentally friendly. Thermoguard Flame Retardant Topcoats are 2010 compliant and safe to use in accordance with manufacturer’s instructions.
The heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building.
Product performance assessment based upon UKAS/EGOLF Fire Test Laboratory Certification to BS 476 Part 21 - Fire resistance to load bearing elements of structures.

| Glen on 2018-12-14 11:17:51 | Question: I need to fire proof previously paint steel beams in a wear-house what would you recommend to get 60mins |
Answer from Rawlins’ Technical Team: Please provide us with as much of the following information as possible; - Level of fire protection required (i.e. 30, 60, 90min, etc.) Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them but in that instance we'd need some guidance as to what to allow for i.e. all steels on first floor, etc. | |
| Tony Auger on 2018-10-18 18:55:19 | Question: I have had two internal RHS ( circular columns) Max. 200mm dia. installed in my house (say 2.50 metres long each) and left exposed (i.e. semi industrial look!) As we wanted this look we have left them as black primed from the fabricator. The building inspector wants these fire painted to 30 minute resistance. What is the best fire paint to use under these circumstances and what finish can we paint over, as we wish to end up with a black and as smooth as possible look ! Also, need a certificate of the compliance. Surface area of max. 4 to 5 M2 to cover. I understand that we may need to apply a white fire paint which can be top coated over in black. Would prefer to brush apply the paints as exposed decorated walls and ceilings surrounding. |
Answer from Rawlins’ Technical Team: 5m of 193.7 CHS (Circular Hollow Section) with a minimum of 4mm wall thickness would give you approximately 3.1m² of surface area to paint. To achieve 30min protection you would require 8 litres of Zeroflame Aquasteel WB+ (assuming all internal, dry environment). Assuming the steel has already been primed with a suitable primer, Zeroflame Aquasteel WB+ can be applied directly over this as long as it is clean and sound (no flaking, rust spots, bare metal areas, etc.). Once applied, Zeroflame Aquasteel WB+ Finish should be applied in the colour of your choice. | |

| Jinni King on 2018-07-09 19:11:40 | Question: Hi, I have a galvanised steel lintel and post to protect to 30mins. Lintel is 3.9m length of 178x102x19 UB to be covered 1 side of the web and both flanges and post is 1.1m tall 120x120x5 SHS to be covered all sides. Could you say how much thermocoat we need and does rawlins supply any suitable primers in suitably small quantities? Are wet thickness gauges included or do we need to order these separately? Regards Jinni |
Answer from Rawlins’ Technical Team: To suitably prepared and primed 178x102x19 UB and 120x120x5 SHS steel apply 600 microns WFT (Wet Film Thickness) of Thermoguard Thermocoat W to achieve 30min protection. The steel once protected with sufficient Thermocoat W must be top coated with 2 coats of Thermoguard Flame Retardant Topcoat assuming the steel is located externally (ensure no areas are horizontal and subject to ponding/standing water). To prepare your new, bare galvanised steel we would recommend Teamac Mordant Solution (T Wash) followed by Thermoguard High Build Metal Primer. Based on the lengths of your steels you would require 5lt of Teamac Mordant Solution (T Wash), 2.5lt of Thermoguard High Build Metal Primer, 5kg of Thermoguard Thermocoat W and 2.5lt of Thermoguard Flame Retardant Topcoat in your chosen colour and finish. It is your responsibility to check the workout against the actual steels, any alterations should be notified before work begins. Wet film gauges are supplied free of charge with any order of Thermocoat W. After use, certification can be applied for here: http://www.thermoguarduk.com/fire-certificates/ | |
| Jayne Halford on 2018-06-26 22:06:50 | Question: The steel beams in my building have been in existence for about twenty - thirty years and therefore already have coats of paint on them. We have recently renovated the building from an old barn to a dwelling and building control want us to use intumescent paint. What do you suggest is the best application and method to achieve a 60 minute fire rating. Many Thanks |
Answer from Rawlins’ Technical Team: In certain instances after extensive testing and approval by Thermoguard, Thermocoat W can be applied to steel with existing (non fire protection) paints to achieve 60 minute protection. To be able to advise whether the steels you have may be suitable, we would first need the following information;

| David Timlin on 2018-06-25 12:28:50 | Question: we have a steel beam 356 x 171 set flush in a wall 7600mm long. need to paint one side only = 2 flanges (171) and web (356) - what thickness (wft) do we apply to get 1 hour fire rating ? Thanks |
Answer from Rawlins’ Technical Team: To suitably prepared and primed 356x171 steel apply 1000 WFT (Wet Film Thickness) of Thermoguard Thermocoat W to achieve 60min protection. The steel once protected with sufficient Thermocoat W must be top coated with 1 coat of Thermoguard Flame Retardant Topcoat assuming the steel is located internally. At 7.6m long this would require 12.5kg of Thermoguard Thermocoat W + 2.5lt of Thermoguard Flame Retardant Topcoat in your chosen colour and finish. After use, certification can be applied for here: http://www.thermoguarduk.com/fire-certificates/ | |
| Cindy Cull on 2018-06-02 10:30:38 | Question: We have a new H RSJ in a ceiling & wall - they are primed & will be covered on plaster board. How many coats will we need for a min 60 mins protective coat? I don't need a top coat because it will be hidden under the plasterboard. |
Answer from Rawlins’ Technical Team: To be able to advise on the number of coats required we would need to know the steel size (i.e. 254x146x37), length, number of sides to paint and orientation (i.e. horizontal or vertical). | |
| kate on 2018-05-02 10:09:27 | Question: Hello, We will have an exposed steel beam in our house and I'm looking to purchase Thermocoat W and then the Thermoguard Flame Retardant Topcoat. Do I also have to purchase the primer or will the termocoat work as a primer? Thanks, Katie |
Answer from Rawlins’ Technical Team: Steel and cast iron should be free from rust and millscale and primed with Thermoguard High Build Metal Primer to 75 microns DFT (or alternative good quality anti-corrosive primer compatible with intumescent paints) in accordance with manufacturers instructions. Treat galvanised surfaces with T Wash/Mordant Solution & prime with zinc phosphate or other suitable primer for steel. | |
| Ian Rennie on 2018-02-08 11:25:38 | Question: Our project involves repainting 50 metres of steel beams which are already coated in white eggshell finish intumescent paint to a 90 minute fire protection. We are to repaint these beams as the lease is finished and the offices have to be repainted, so it is more of a routine repaint rather than protecting vulnerable surfaces as the existing coating is intact. Nonetheless we are required to paint with 90 minute fire protection. So are 2 coats of Thermoguard W required with a top coat or can you advise ? I expect the beams are a standard 400 mm size. |
Answer from Rawlins’ Technical Team: Thermoguard Flame Retardant Topcoat can be used to redecorate and Thermoguard would certify it maintains existing fire protection, whatever that may be. However a Fire Certificate can only be issued for 90 mins if Thermoguard assess and are able to find they can propose a method to apply Thermoguard Thermocoat W over what is left of existing basecoat after removal of overcoat, plus high spots or upper layer of existing intumescent via electric hand tool abrasion.

| john doody on 2016-11-22 15:15:30 | Question: hi we are looking for a minimum 60 minute fire protection, to the bottom section only ( rest of steel is built in) of an exposed steel beam above the entrance to an integral car port. we have approx. 60mtrs x 400mm wide to protect thickness of bottom flange approx. 35mm.regardsjohn doody |
Answer from Rawlins’ Technical Team: To achieve 60min protection on your steel, apply Thermoguard Thermocoat W @ 450 microns WFT. Followed by (once dry) 2 coats of Thermoguard Flame Retardant Topcoat in Eggshell or Gloss finish in the desired RAL or BS colour. Steel must be clean, dry and well primed (no bare areas, rust or other paints/coatings present). Fire Certificate issued free of charge upon application, Wet Film Gauges supplied to measure as you go to ensure correct thickness is achieved. Materials required for this project are as follows;

Answer from Rawlins’ Technical Team: To provide any information in relation to coverage or film thickness required for Thermoguard Thermocoat W we first need to know some details of the steel requiring protection. Please contact our Technical Department on 0113 2455450 or [email protected]. Please provide us with as much of the following information as possible;
Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them. | |
| mark on 2015-12-03 09:25:33 | Question: How far will a 5kg of Thermoguard Thermocoat W paint in surface area? Can you paint this on wooden surfaces? |
Answer from Rawlins’ Technical Team: Thermoguard Thermocoat W is for use on steel and the coverage is determined by the level of fire protection required (30min, 60min, etc.) and the size of the steels to be protected. If you require fire protection for wood see Thermoguard Timbercoat. | |
