Rustins Wood Hardener for Rotted Wood 250ml

I used Rustins Wood Hardener on several rotten timber areas and it genuinely transformed soft crumbling wood into a solid stable surface. It penetrates well, dries fast and creates a tough plastic like finish that’s perfect for filling or repainting. It’s easy to apply but wear gloves, once it’s on your skin it’s a nightmare to remove. The results are excellent and it’s saved me from replacing window frames and sills. A reliable product I’d happily buy again.

Where a filtered air mask when using this stuff. It has the consistency of thin treacle and provides a waterproof barrier on wood (rotten or sound) after it's dried. It worked well, but I ended up using both 500ml tins on the same very small area and still need more, so value wise, next time I will be looking for a much bigger quantity, probably 5 litres+ It appears to have hardened both rotten timber and the sound timber next to it, the first coat does take a fair while to soak in, even in the hot weather we've had lately, the second coat dried to a shine. Wear gloves and keep away from it while it's drying, as it dries it becomes very sticky, when fully dried it is not sticky at all. If you get it on your skin, wash it off immediately with washing up liquid & water or it will stain your skin and the compounds contained it can enter your body through your skin.

This really works ,I couldn't do as much prep on my decayed part of the fence as stated as the wood would have crumbled so I was unsure if this would work.It returned my piece of fence to a solid piece of wood again absolutely perfect.It smells harsh but well with it

Really goid product, literally does what it says on the tin. Used to restore an old storage crate which had been riddled by woodworm. Part of the wood was almost like paper where you could squish it by hand. This has hardened the wood to the point where it is now stable and no longer disintegrating. It has left a slight sheen to the wood , rather than shiny and darkened it slightly but the darker colour may be because this wood had been left untreated for so long. The easy was was to treat the entire lights of wood so it all looks the same. But as the crate is an old apple crate using different types and thicknesses of wood it blends in quite well. Would rather have it the way it looks now than in danger of falling apart and worried about moving it. Don't get me wrong I wouldn't lift it up by the treated piece as I dont think it would bear the weight. But it has definitely stabilised and strengthened the wood to an almost miraculous level. Very happy with this product and would definitely use/ buy again Follow the instructions, wear gloves and clothes you dont mind getting soiled. And if possible work outside as a very strong smell. If workung inside iluse in a well ventilated area as it has a very strong smell ( similar to turps or paint thinners).

This product is absolutely perfect does exactly what it says on the tin...rotten timber it actually hardens it to screw to brilliant.

I used Rustins Wood Hardener for Rotted Wood (500 ml) on some areas of exterior timber that had started to soften due to rot. In terms of function, the product does what it is designed to do. It soaks into deteriorating wood fibres and helps stabilise them, leaving the timber noticeably firmer once it has cured. The liquid itself is very thin and penetrates well into soft wood, which makes it effective for consolidating damaged areas before filling or repairing. Application is straightforward with a brush, and it spreads easily over the affected timber. However, the biggest issue with this product is the very strong smell and fumes. The odour is extremely powerful and lingers for quite a long time after application. Even with good ventilation, the fumes are quite unpleasant and can quickly make an indoor environment uncomfortable to work in. Because of this, I would strongly recommend using it outdoors or in very well-ventilated areas only. If you do need to use it inside, proper ventilation and possibly a respirator would be sensible precautions. In summary, it is an effective wood hardener that does its job, but the fumes are significant and something buyers should be aware of before using it indoors.

Great product, really hardened the rotted wood to allow a good repair. Enough for lots of repairs but hope I don’t need it all. Exactly what I was looking for.

Is a rather oily product takes a while to sink in; I usually use the more liquid variety, goes into the wood/rot quicker and I would imagine deeper down into the wood.
