Features & Benefits
Easy to apply
Quickly penetrates the surface of the substrate with high diffusion properties
Does not require a protective finishing coat and can be left natural or, if specified, over-coated (left naturally, timber may darken slightly)
Non-flammable properties which restrict ignition and the spread of flame
Will not wash out once dry
Not converted into smoke when exposed to high temperatures
Carbon char is restricted to the immediate area
Treated materials, when exposed to temperatures of up to 1700°C, are subject to charcoal forming, restricting the spread of flame
For use on cladding, staircases, trusses, joists, walls, log cabins, garages, pool enclosures, saunas and many other projects both inside and outside
Coverage rate 2 Coats @ 8 m² per litre per coat Or 3 Coats @ 12 m² per litre per coat. Number of coats dependent on substrate porosity
Minimum of 1 hour between coats. Full drying time approximately 24 hours at + 20°C / 65° relative humidity, with maximum fire retarding capabilities achieved after 7 days

Hi there I’m looking into using this on a woodland playground. So I need to know if it’s toxic to animals/ plants and it’s safe to use around kids equipment? Also would it be ok to use outside.
Answer from Rawlins’ Technical Team:
This product has not been tested as animal/ plant safe so unfortunately we cannot confirm this.

Question:
We are required by building regulations to use this to coat external wood cladding on the side of our house. The wood is European oak. The new oak is a yellow colour when first put up, but it turns to silver after a year or so. Will this solution stop this natural fading or will the wood continue to do this? We want it to turn to silver! Thanks.
Answer from Rawlins’ Technical Team:
Hydron Nu-Flame Clear Impregnation offers protection against the spread of fire but not protection against UV so it will not prevent the natural silvering of the timber.

Question:
Will Class 0 Certification be maintained if product is applied to new timber and then overcoated with a water based stain such as 'Ronseal One Coat'?
Answer from Rawlins’ Technical Team:
The product data sheet states;
Over-coating: Any treated timber which is to be over-coated with a varnish, stain or paint should be tested for adhesion and compatibility purposes prior to fully over-coating. It is advisable to overcoat with water based or acrylic decorative paint finishes to ensure that the fire retardant properties are not compromised.

Question:
Please can you advise if this has been tested re: class 0 surface spread of flame and if so, where cam i download the certification?
Answer from Rawlins’ Technical Team:
Hydron Nu-Flame Clear Impregnation has been tested to achieve Class 0 surface spread of flame on both interior and exterior timber. A certificate of supply can be requested following purchase and application but if you require any testing information prior to any purchase this would need to be requested from the manufacturer directly.

Question:
Is this product compatible with Sadoline extra wood stain and berrettine used as an overcoat ?(https://www.google.com/shopping/product/17066715910191917418/image?hl=en-GB&ie=UTF-8&q=sadoline+extra&gws_rd=ssl&prds=cid:17066715910191917418,sgro:iv,cs:1&sa=X&ved=2ahUKEwj2-MCr2IXfAhVKBMAKHTnDAHwQ-K4BegUIDxCkAQ) or berrettine (https://www.google.com/search?q=barrettine&hl=en-GB&source=android-browser&prmd=smivn&source=lnms&tbm=isch&sa=X&ved=2ahUKEwirhoXm2YXfAhXoIcAKHV6lBocQ_AUoA3oECBYQAw&biw=360&bih=525#imgrc=M-fpWqFCkQLr_M:&isa=y) .
Answer from Rawlins’ Technical Team:
Always difficult to determine the overcoating effect;
Sadolin in wet form White Spirit & Naptha based, not a good start
Barrettine in wet form Oil / Solvent / Spirit based, again not a good start
White Spirit & Naptha will logically at some stage evaporate off, leaving whatever it is carried in
Oil could theoretically remain indefinitely re-contributing to overall flammability
Plus of course the compatibility issues between an oil based & water based products, causing all sorts of problems, including blooming.
There are more compatible finishes available, generally the water based finishes are better suited.
This knapsack sprayer has a capacity of 16L of liquid and is perfect to perform a versatile range of tasks.
Suitable tasks include killing weeds to spraying fences
Fire retardant fluids such as Zeroflame Fire Retardant Treatment, Thermoguard Thermoproof Exterior Fluid and Hydron Nu-Flame Clear Impregnation can be easily applied with this...
