Product information
Ronseal Wet Rot Wood Harder Reinforces decayed wood. Creating a solid base for filling.
- Guarantee - Statutory
- Suitable for Decayed wood
- Wear protective gloves to avoid getting hardener on your skin. Open your doors and windows for added ventilation. Remove loose or crumbling wood and make sure the area is dry. For the best repairs, drill small holes into the wood so hardener can get in deeper.
- Give the tin a thorough shake. Pour some of the hardener out into the plastic lid. Apply it with a paint brush. Make sure you get enough on so that it completely soaks into the rotten wood. Leave it to dry for two hours. Scrub with a wire brush to get rid of any excess hardener. Clean your tools with white spirit.
- Instructions for Use - Give the tin a thorough shake. Pour some of the hardener out into the plastic lid. Apply it with a paint brush. Make sure you get enough on so that it completely soaks into the rotten wood. Leave it to dry for two hours. Scrub with a wire brush to get rid of any excess hardener.

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!

Absolutely does what it says. Great purchase. Would recommend.

A great and useful product.
Recently purchased this to help repair a wooden table top. Easy to apply, works well. Have used it before many years ago and it’s still as good.

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.
