Best stuff ever
This is the best wood harder I have ever bought and I have bought a lot of different brands. This is excellent stuff it dries quickly and it does the job perfectly. I highly recommend it. Its consistency is good. It’s water resistant good application good coverage and it protects the wood really well.

Works well
Painted on as indicated. Left to dry until next day. Really does harden the wood. Filled and painted. Success.

It Works
Follow the instructions and you can’t go wrong, something that actually works, not just for the short time but for all time.

Brilliant
Used this on my garden gate which had a couple of soft spots where rot is setting in. Wow! The areas I applied were spongy and are now rock hard!! No doubt I'll need to address the issue properly when the weather is better but this will hopefully stop the rot and get me though winter. Brilliant! Edit - A week later and the area was spongy again. No real fault of the product as it does state to remove any loose or crumbling wood. I was hoping for a quick fix but I have now removed the rotting wood and reapplied. I will report back. Edit: So I would definitely recommend following the instructions! After removing the soft wood I applied this which now gives me a solid base to add somewood filler. Don't do what I did and try and cut corners as you will only waste the solution and need to reapply.

Does what it says on the tin?
I used Ronseal Wet Rot Wood Hardener on a damp window frame and was impressed. It soaked in well, solidifying the soft, rotten wood and giving me something strong to rebuild from. The 250ml size was easy to handle and applied smoothly with a brush. It’s a handy product if you want to rescue wood rather than replace it — simple and effective.

Billiger Kleber zum teuren Preis
Wirkt wie ein normaler Kunstoffkleber, nir zum x-fachen Preis. Hat bei mir in keinster Weise das gehalten, was versprochen wurde.

sconsigliato
profonda delusione per questo prodotto, non fa nulla di più che potrebbe fare una soluzione di colla vinilica in acqua. Oltre a non riempire il legno deteriorato rimane fragile come in partenza.
