Nu-Flame Clear Impregnation is a fire retardant ready-to-use system that is absorbed into the surface of timber. Ideal for timber substrates that require Class `0` Spread of Flame or Euro class B.
**Available for delivery - see Delivery Options below**
Easy to apply, the Nu-Flame Clear Impregnation system is a ready-to-use solution that is absorbed into the surface of timber. Although the solution is clear, the timber may darken slightly. Ideal for timber substrates that require Class '0' Spread of Flame or Euro class B. This fire retardant system is perfect for all wooden structures such as loft flooring, garages and timber dwellings.
Materials treated with Nu-Flame Clear Impregnation when exposed to temperatures of up to 1700°C are subject to charcoal forming, restricting the spread of flame.
Nu-Flame Clear Impregnation for use on cladding, staircases, trusses, joists, walls, log cabins, garages, pool enclosures, saunas and many other projects both inside and outside. Ensure surfaces to be treated are clean, free from contamination and dry; remove existing coatings by stripping or sanding. Best results obtained when moisture content is less than 20%.
Do not mix with other solutions, stir well. Use brush, roller, spray (use appropriate mask), dip, or vacuum method. A small area of the substrate should be tested for compatibility before the full final coat is applied. Clean equipment with water immediately after use. Either 2 coats @ 8m²/Litre per coat, or 3 coats @ 12m²/Litre per coat depending on moisture content of the substrate and atmospheric conditions. Coats should be applied at intervals of 1 hour minimum. Do not mix with other solutions, stir well. Minimum temperature for application 5°C. Clean equipment with water immediately after use.
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.
A minimum of 1 hour between coats. Full drying time approximately 24 hours at + 20°C / 65° relative humidity. Maximum fire retarding capabilities are achieved after 7 days. Drying times are dependent upon absorption of substrate and drying conditions. At low temperatures and / or conditions of high relative humidity, drying times will be extended
Store away from direct sunlight and sources of heat. Protect from frost.

![]() | Question:
Could you tell me how any square meters 5L will cover please. |
Answer:
The product will protect 20m² of timber per 5lt. | |
![]() | 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:
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:
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:
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: 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. | |
