Best Wood Preserver

A wood preserver does a whole lot more than bring out the wood’s natural beauty – it forms a protective shield which prevents damage from a number of different problems.

Outdoors, this will include a wide variety of weather conditions, such as rain, frost, and UV rays. Not to mention the likes of moss, mould and algae.

Indoor problems meanwhile include general rot and insect infestation.

Our rating:

This is a great wood preserver from Everbuild (AKA Sika) – after over 100 customer ratings on Amazon, it still comes out as a whopping 4 and a half stars out of 5 on average.

Again this is a wood preserver that can be used both indoors and outdoors.

This wood preserver is absolutely packed with features.

It has a specially designed formula to give it deep penetration into the wood for truly long lasting protection. Protection against wet rot, dry rot, decay and fungi.

To help with this it has Fungicides and algaecides which are finely dispersed throughout the formula, to make it that much more effective.

The coloured variants are designed to produce a fade resistant finish, and this is thanks to its use of ultra-lightfast pigments. The colour variants are understated and will not leave your wood looking garish or odd.

It doesn’t have that overpowering scent you can get with some wood preservers, making it that much more pleasant to work with.

It’s fast drying, it’s non-flammable, and can even be applied to wet or damp timbers.

Despite coming in such a large tin, 5 litres, it’s still a very reasonable price – and it qualifies for free delivery from Amazon.

Best Wood Preserver – Buyer’s Guide

The most important thing to remember when buying a wood preserver is that you have to buy it according to its intended use. Wood preserver designed for use on outdoor features for example, can do a whole lot more than wood preserver designed for indoor use.

Oil or wax based preserver

Examples of exterior wood preserver include oil or wax based types. They are formulated with solvents such as wax, boiled linseed oil, and mineral spirits.

These have a distinctive (sometimes overpowering and a little unpleasant) scent, and usually leave a shiny finish, and can often change the colour of the wood and can affect how easy it is to paint. It prevents cracks from forming in the wood, as well as swelling and separation at the grains.

Water based wood preserver

Water based wood preserver on the other hand features small amounts of chemicals, suspended in water, which are able to deeply penetrate in the woodwork. This enables it to work from the inside to kill any woodworm or algae.

Water based wood preserver is best suited for ground woodwork, such as decking. They produce no odor and are safe to use around plants and pets.

Waterproof finish

Some wood preservers can provide a waterproof finish, which can help to prevent rot and decay. As to whether you need a waterproof finish depends on matters such as not just whether or not the woodwork is outdoors, but also when whether you wish to varnish it afterward or paint it. Some wood preserver brands also produce waterproofing sealers.

Clear or coloured wood preserver?

Choosing between clear and coloured wood preserver is not just about aesthetics. Clear wood preserver offers greater protection against UV rays and are better able to repel rain water and resist fungus growth.

Of course looking into coloured wood preserver may seem to provide more colour options, but clear wood preserver allows for overcoating in your choice of varnish or paint.

Cost

Ever heard the phrase “buy cheap, buy twice”? That applies here. The high end wood preservers offer a truly great and long lasting performance. Whereas cheaper options don’t have the same level of quality. If in doubt try to go for a brand you’ve heard of.

Frequently Asked Questions

How do you look after wooden furniture?

The first step to looking after your wooden furniture, whether indoors or outdoors, is to apply wood preserver. This prevents it from wet rot and dry rot, and sometimes includes pesticides to kill off any woodworm or fungi.

You should avoid any heat damage which can be caused by placing hot mugs or plates on it. You should also keep your wood clean by dusting regularly and clean it by using cleaning products that are designed to be used on wood – do not use all purpose cleaners. You can find such products on Amazon. Polish helps too.

Always treat any wear and tear, for example by using a scratch cover if you get a nick or a scratch. The same goes for tough stains, the quicker you are to deal with it the easier it will come off. When it comes to how to remove tough stains there are a lot of home remedies that can usually do the trick.

Are wood floors easy to maintain?

Wooden floors are very easy to maintain when you use the right products. Even areas that have become dull or worn in highly used areas can be easily restored without the need for any sanding. Our recommendation is to apply a hard-wax maintenance oil every 6 to 10 months. This should get them looking like new again.

What is the best sealer for wood?

Once you’ve treated your wood and applied your wood preserver it’s a good idea to seal it, especially for any outdoor wood such as on fences, sheds or decking. Sealing wood prevents moisture from seeping in through prolonged spells of heavy rain and condensation.

Many people prefer to seal wood rather than to paint it in order to maintain the original appearance of the wood. Everbuild does a good water seal, and you can find it on Amazon. Here is the link.

How long does wood preserver last?

If your outdoor wood (shed, fence or decking) has no other covering other than wood preserver, then you should reapply wood preserver once a year to keep it in top nic.

How many coats of wood preserver do I need to apply?

The general rule in applying wood preserver is to paint 2 coats altogether, allowing the first coat to dry before applying the second coat.

What are the 3 types of wood preservatives?

The 3 types of wood preservatives are water-borne preservatives, oil-borne preservatives, and light organic solvent preservatives.

What can you put on wood to protect it outside?

For outdoor wood (shed, fence or decking) we strongly recommend that you apply wood preserver as soon as possible once bought.

But protecting your wood from damage does not have to end there. You can apply a waterproofing sealant, or you can stain it, or varnish it or even paint it.

Is wood preserver waterproof?

The short answer is no, not usually. There are some wood preservers which offer waterproofing but these are generally few and far between.

If you cannot get a waterproof wood preserver, that shouldn’t present a problem as there are a myriad of different things you can do to the wood which can alter the extent to which the wood is waterproofed. The best advice we can suggest however is to buy a waterproofing sealer from the same brand as your wood preserver, so you can be assured that the 2 are compatible and that each will compliment the other.

Can I paint over wood preserver?

You certainly can paint over wood preserver, but you must ensure that the wood preserver has set first.

How long does wood preserver take to dry?

How long wood preserver takes to dry very much depends on the weather conditions. Most wood preservers recommend that you apply two coats of it altogether.
