Wood preservative/hardener in the UK

Post  Treebeard on Mon Sep 07, 2009 8:32 pm

Can someone recommend a wood hardener or preservative that is safe for plants and readily available in the UK? I've got a project in mind that will require that I protect quite a bit of wood from rot. I figure that bog-standard cuprinol wood preservative will do the job, but if that is not suitable for some reason that I haven't thought of then I'd appreciate some pointers to other products.

Hi Chris,

I ave used the stuff from Kaizen on my hawthorns... it DOES work... but only to a point... the 'deadwood' eventually turns to a 'papery' texture and crumbles... so my course of action is to simply let the tree rot.

I have preserved Juniper deadwood that I am creating a Tanuki with clear Cuprinol... soaking the bottom of the wood for a week. Then leaving the wood for six months to the elements before attaching the live. That was 12 years ago... and the wood is STILL ok.

Good look with your project bounce

You might try a marine epoxy. I've talked to people who have used it on their trees, but on trees that already had some rot in the deadwood. The scraped away ALL of the rotted wood, mixed the epoxy and applied it. I think it dries glossy, so you'd probably have to take a wire brush on a rotary tool to it. I doubt you could use lime sulfur to whiten the wood afterward.

Hi Chris. I have been using Ronseal wet rot wood hardener for a number of years now and it works very well. It is a spirit based chemical that dries to a resin.

Will, do you use that alone or in combination with lime sulphur for deadwood? If you use both, does the Ronseal go on before or after the lime sulphur?


On another note I can confirm that the Ronseal product also works well on kitchen floors... Embarassed

I use the Ronseal purely on non resinous deadwood. The product is clear and dries with a shiny finish. Once dry though, when you water the whole of your tree it goes matt. Ronseal not only protects the wood ,it also preserves the natural colour. I do not like the colour of lime sulphur as it is an unnatural colour.I understand why its used to give great contrast between alive and dead, but prefer to see it toned down by a couple of years or a pigment mixed with it. Teak oil is also good but has to be applied quite often.

Many thanks for the replies, I've now got some options to work with. Down to homebase at the weekend for me Smile

The wood will be partially buried in soil, so it will be subject to a bit more wet than if it was above soil.

What type of wood are you using? Some hardwoods do verywell underground, some not so.

At least for the parts that will be underground, I'd strongly suggest the marine epoxy.

That wood hardener that Will describes sounds very much like the MinWax Wood Hardener we use over here. It requires periodic reapplication for wood that is merely exposed to the air and dampness, and does little lasting good underground.

Jim is quite correct. I have an English Elm thatwas the guinea pig, nearly ten years ago. Ineed to do some work on the deadwood as at soil level it has gone soft but everything above soil level is as hard as ... er ...wood. I do treat once a year.

It's mopani, the kind that goes into aquariums for decoration. I figure that it must have some inherent resistance to rot but I'm trying to cover every eventuality.

Hi Chris, I used to live in Zim & Botswana where Mopani trees abound, it appears that the wood is resistant to water due to its density and oiliness. If continually saturated is is likely to last for decades, it is however prone to break down faster if saturated, dried, saturated, etc. A potential problem area would be just above the soil line where this is bound to happen.
