Overview

Ronseal Wet Rot Wood Hardener has been designed to soak into the fibres of rotten wood. Once dry, the special resins harden, strengthening and reinforcing the softened wood, forming a good solid base for filling, as well as sealing against further moisture penetration.

Preparation

Ensure that wood to be treated is reasonably dry and free from grease, oil, dust and loose particles before application.

  • Remove any completely decayed or very soft crumbly wood until a fairly sound base is
    exposed
  • For the best results, drill small holes into the damaged area to achieve an even deeper hardening
    of rotten wood

Application

How To Treat Rotten Wood

Always do a small test area before starting any project to assess performance and follow the manufacturer's instructions on the tin at all times. If indoors, open doors and windows to provide proper ventilation. Shake the tin thoroughly before opening.

  1. Decant a small amount of wood hardener into the lid of the tin or other small container
  2. Apply wood rot hardener to the softened wood with a paint brush
  3. Soak the affected area to ensure full absorption of the hardener
  4. Leave for 2 hours then remove any excess wood hardener with a stiff brush
  5. Use Ronseal High Performance Wood Filler to fill and finish the damaged area
  6. Sand off any surface wood hardener prior to painting or finishing

Please Note: Avoid contact with glass, metal, plastic and painted surfaces during the application process. Do not use this product as a surface treatment or primer.

Very good product does what it says on the tin

As I have said, a very good product. One thing, when you send in email to review your product, you do not say what product you are talking about, which would help enormously, and save the customer wasted time looking up what product you are talking about. And I think you will get a lot more replies from customers.

Perfect

Superb rapid delivery service, excellent packaging, and great products at good prices. Also clear helpful technical advice. Highly recommended in every respect. The products I use are made by Osmo and include UV Protection Oil.

Very easy to use and very effective.

Did nearly everything I wanted and was certainly effective. Only niggle was I couldn't get it to colour match the existing wood. Doesn't affect the fact I would use it again.

Great invention

Used this on a rotting pressure-treated fence in autumn and despite the wet and now freezing weather conditions it is holding up well even though I have not yet got round to painting the fence. Very impressed.

Does the job

Probably not ideal on large area's but we used it for ends of decking which were starting to rot, will hold up a few more years now I should think!

Worked well on the manky bits of our gate!

Had some rot in places on a gate and this seems to have sorted it out well.

Does what it says on the tin

Ideal for the job.

I repaired my garage doors. some wood had to be replaced, but other parts just had small areas of rot. I removed the rot and treated with the hardener, then PVA'd a new piece of wood in. (Waterproof PVA) This is then sanded to finish. I have used it on the corner of wooden windows as well prior to filling and finishing. Works very well. If you put a lot on to soak in, it will be have to left for 24hrs to dry.

Good product

A bit expensive but works very well as a wood hardener.

Experimental use

I recently built a pergola with bench swing and I want it to last for many years through the rains of the Lake District. I bought this product thinking that, if I gave the timber a brushover with it before applying my final coat, it will enhance the chances of longevity. Not sure if I'm right .. time will tell .. but the rain certainly seems to roll off the timber more freely, so the signs are good.

Have used this a number of times. Avoids removing all rotten wood in places where it would be very difficult and time consuming though a sensible judgement must be made

Protection for strengthening wood

This is a very good product for reinforcing any wood that looks as if it may be effected by water as it hardens any soft wood that may have been effected so instead of splicing a new piece of wood in this product can save this process.

Wet rot magic potion

I have used it various times and each time I am amazed how one can save existing timbers with this magic potion. Just remove the worst wet rot, treat the area, wait for drying, once rock hard fill with proprietary wood filler and finish as you like it to blend in with the rest... Very recommendable, worth every drop!
