This is great product
A very good product, I'm very satisfied. The rotten slats were glued together, and now it's hard as a rock. I highly recommend it!

So easy to use. Really good hardener. In or out.
Absolutely does what it says. Great purchase. Would recommend.

Useful kit
I’ve used this before and needed to replace the tin to complete a small repair to a wooden porch

Works well
Treated a rotten area of my outside roofing, perfect, unfortunately the same cannot be said about the Ronseal Filler.

Great product
This worked great on a rotting windowsill. Easy to apply and quick drying and could feel that wood felt harder post application and I was then able to fill hope with wood filler, avoiding the need to replace the whole windowsill.

It does what it says on the tin!
I used this at the bottom of an external wooden door frame. I removed the worst section and used the wood hardener to harden the surrounding area before filling with external filler and repainting. It looks as good as new.

Worked for me!
Used to treat wet rot around base of old shed. Easy to apply and has dried hard.

Stayed sticky for days
I needed to stop rot in a roof timber and scraped away all the affected wood before applying. I used a few tins of this to absolutely soak the wood. It stayed sticky to touch for days before setting hard. I think if you use less. It may dry in the indicated 2hrs!

Great product
Excellent stuff. Bit sticky if you get it on your hands.
