Review: Does what it says on the tin ! - 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).
Review: Works a treat - I use this to repair exterior wood door/window frames etc., applied before filling with Toupret wood filler. It brushes on well, wood takes it up easily, and any excess will evaporate or harden anyway (just may take longer than stated drying time). Only docking a star because as nice as the tin is, it's not easily poured, does leave some inaccessible and wasted, and I have had it harden in tin from poor lid seal.

## Questions & Answers

**Q: Would you use this on the whole area**
A: It's only required on the rotted area.  Cover the entire rotted area, allow to dry then rub down.

**Q: How long between applying coats?**
A: About four hours. Longer if colder. If you are using wood filler allow about 12 hours after wood hardener is applied.

**Q: Under the cap, there’s a little metal lid that seems to be welded on!! Any advice on how to take it off safely? I’ve tried a stanley knife but nope.**
A: I used a screwdriver to prize it off. Not easy but don't worry about destroying the metal lid.

**Q: Does this dry clear, or milky white?**
A: It dries clear unless it gets wet before drying - then it is milky white - I found the same with the Ronseal product

### ⭐⭐⭐⭐⭐ Does what it says on the tin !

### ⭐⭐⭐⭐⭐ This Stuff is Amazing!!
*by M***! on 20 July 2025*

This is a thin resin type material. It reminds me of the liquid used for fibre-glass, or perhaps a thin version of PU glue. It's stinky and pretty horrible if you get it on your fingers. It's readily absorbed by wood, and the end effect is rather like painting it with yacht varnish, except it's rock hard in two hours. It sets like plastic so the surface is water repellent and tough. Looks like a varnish, so you may not need any finishing at all, or seems to be a good base for paint. All in all it's a fantastic product. This is the first time I have used it, it won't be the last. I had imagined this to be absorbed like a very thin liquid and to then convert all the soft wood to something really hard. That's not really what it does. Yes, there is some absorption, but not much. It forms a solid, yes, but only the top of the treated wood. So, I think the way to proceed is to thoroughly soak the wood with preservative, then when that's dry, hit it with this to form a water resistant surface that protects and provides a great key for filler. Highly recommended.
