Everyone has heard of wood preservers but what are they, why are they so important and how do they work?
Although wood is an amazingly versatile and durable material, it can be susceptible to deterioration, especially so in environments where mould, algae, fungi and wood-boring insects are likely. The best way to protect and preserve wood, including timbers that have been tanalised or pressure-treated is to use a best clear wood preserver.
Top 10 the best clear wood preserver in UK 2021
Here’s our top 10 pick of the best clear wood preserver for you to buy in UK 2021.
1. Sikagard Wood Preserver
This clear, water-based, microporous wood preserver gets right into timber to protect it from algae, moss, fungi, wood-boring insects and so on. You can even apply it to damp wood that’s seen better days and it’ll start to work straight away. What it can’t do, though, is provide a water-repellent finish, so you’ll need an additional topcoat.
Luckily you’ll find it easy to apply any kind of topcoat you like over this preserver because it absorbs completely and doesn’t leave any sticky residue. It’s also quite thin, but that makes it easier to apply with a sprayer to cover a large area.
2. Cuprinol 5L Wood Preserver
Colourless, with a low odour formula, you can use this product both indoors and outdoors, wherever you wish to protect and preserve the wood. When using it outdoors, however, bear in mind that you will need a minimum of two treatments and that it is only to be used as a base coat before painting, varnishing or staining as it does not contain a UV filter.
This five-litre container will cover up to five metres squared per litre with two coats. It will actively prevent rot and decay, preserving your fencing, decking, or garden shed for many years to come.
3. Roxil Wood Preserver
Roxil Wood Preserver is a solvent-free liquid wood preservative designed to penetrate deeply into timber and defend against dry rot, wet rot, fungal attack and woodworm infestation. This powerful formulation can be applied by brush or roller to help protect outdoor wood such as: fence, decking, sheds, garden furniture and more.
This is a colourless liquid water repellent for use on timber in either indoor or outdoor environments. Once applied by brush or spray, it will make the surface of the wood hydrophobic, protecting it from the undesirable effects of moisture ingress.
4. Everbuild Wood Preserver
Everbuild Wood Preserver is a low solvent, low odour solution based on Micro-fine active technology. The fungicides and algaecides present in these formulations are finely dispersed so that wood penetration and hence effectiveness is much greater than standard wood preservation products. In addition the use of ultra light fast pigments on the coloured variants give an even fade resistant finish which will last for years.
Everbuild Wood Preserveris fast drying and non flammable; and application to wet timbers is possible without loss of performance. It is specifically designed to deeply penetrate all wood and joinery to give long lasting protection from damage caused by wet rot, dry rot, decay and fungi.
5. Everbuild Triple Action
Wood is bound to destruct over time and if that is something you wish to avoid for good, the Everbuild Triple Action Wood Treatment is one of the best options to take a peek into. It is completely a low odor and low solvent solution which is formulated with the micro-fine technology to it. It contains Permethrin in it which helps ensure that you wouldn’t have to worry about any form of microbial attack on the wood.
It is completely non-flammable and dries down quite easily without the emission of any form of characteristic odor altogether. It penetrates deep into the wood to ensure the maximum protection without imposing any form of toxic impacts on one’s health.
6. Roxil Wood Protection Cream
Roxil Wood Protection Cream is a colourless cream that gives softwood a water resistant silicone coat that also penetrates the fibres to help prevent rot. The cream is white when you apply it to give a trace and help achieve even coverage but it dries as clear as water with no sheen.
It is said to give protection for 10 years and re-coating requires nothing more than a quick clean down, preferably with Roxil wood and patio cleaner to help eliminate any bio mould growth. There is no need for sanding or keying of the surface because the protection cream is absorbed rather than sitting on the surface.
7. Ronseal Total Wood Preserver
Ronseal Total Wood Preserver is a traditional, highly penetrative wood preserver that provides long lasting protection to exterior wood. Our one slight gripe about this product is that it does seem to be on the thin side, which makes it rather easy to spill when the can is full. On the plus side, this does make it very easy to apply and is probably part of the reason why it dries so quickly.
Please note that while you can apply this product with a brush, a spray or by dipping the wood, rather ironically, it’s not suitable for use with Ronseal sprayers. We’re guessing that this is because it is an oil-based product, as you will quickly be able to tell from the smell, which is why we’d keep this product for use as an exterior wood preservative. If you must use it indoors, then we strongly recommend you use it in a room with excellent ventilation.
8. Palace Langlow Wood Preserver
Palace Langlow Wood Preserver is a great solution to protect your shed, fences, summerhouse or log cabin or other timber furniture or landscaping products. The product has a low odour and perfect to protect against water.
Langlow Wood Preserver produces effective and long-term protection against wood rotting fungi & wood boring insects. The non-flammable solvent enables the active biocidal compounds to achieve deep penetration into most common sizes of structural timber.
9. Rustins Advanced Wood Preserver
Advanced Wood Preserver is a low odour, non-flammable product based on micro emulsion nanotechnology. The ultra-fine particle size allows deep penetration of the preserver to take place so the performance of the product is much greater than standard wood preservation products. It is quick drying and can be applied to wet or dry timbers. For use against wood rotting fungi within domestic, commercial, institutional and industrial premises.
10. Roxil Wood Filler
Roxil Wood Filler is a Premium Quality 2-part wood repair and restauration solution. It is designed to be safe, easy & pleasant to use by Amateurs and provide the high performance needed for Professional standards.
Roxil Wood Filler does not contain styrene and is not a health hazard material, making it safer to use. The high-quality formulation has excellent moulding, adhesive and sanding properties, making it a pleasure to work with and enabling even the most novice to get it right on first attempt.
How to choose the best clear wood preserver
Because of tightening legislation on the ingredients that can be used, most wood preservatives are now based on similar formulas. They may have slightly different formulations and ingredients, but they all work in a similar way to protect wood from environmental threats. From a user perspective the deciding factor usually comes down to whether a clear or coloured preservative is needed and if a water-based or solvent-based formula is preferred.
Clear preservers help to retain the natural appearance of the wood whilst coloured versions act as a dual-purpose wood preserver and stain. Most preservers were traditionally solvent-based but more and more manufacturers are changing these to water-based formulas to conform to strict V.O.C (Volatile Organic Compounds) regulations being imposed by UK, European and Worldwide governments.
All wood, new and old should be treated with a fungicidal wash or multicide wood cleaner before treating with a wood preserver. Why? Wood only needs to get wet or damp once for mould and algae spores to establish themselves in the wood grain. This can happen at any time in the transit or storage of the timber or the finished article including sheds, fences and decking boards.
Hope that our list and guide’ve helped you to make the wise decision of the best clear wood preserver!
