You could throw away your old wooden furniture and fixings. Or you could mend it. These days, as the reclaiming, recycling and re-purposing revolution rumbles on and our throw-away culture dies a long-deserved death, more and more people are prepared to make do and mend than throw something perfectly good away just because it’s damaged, old or less than perfect. As a result we’re seeing a significant increase in wood filler sales. But why, when and how do you use them? Here’s our dummies guide…
Using Wood Fillers – What You Should Know
First, what exactly is a wood filler, AKA ‘wood putty’, ‘grain filler’ or ‘plastic wood’? According to Wikipedia, it is:
Wood fillers can also be made of synthetic materials that will often accept wood finishing products. Sometimes, these are available in pre-tinted colours which cannot be coloured further, other than by painting over them.
You can completely hide holes and other damage using wood filling products, which is great news if a beloved piece of furniture, expensive wooden floor or exterior wood needs some TLC to bring it back to vibrant life.

You can buy pre-coloured products especially for certain woods. Take Osmo Wood Filler, which comes in a wide variety of attractive colours designed to match woods like antique Oak, Beech, Cherry, Ebony, Pine, Spruce and even exotica like Jatoba wood.
Four key ways to use wood filling products
The best quality products are incredibly versatile. You can use them in four key ways:
- To fill holes and cracks – You need a thick filler to fill cracks and holes in wood. But you have to prepare the inside of the hole or crack first so the filler sticks properly. Sand the inside of the hole of gap if you can and remove every speck of dust – vacuuming is ideal. Then use a putty knife to force the product into the hole. Smooth the top surface and once it’s dry sand it until you get an even finish, flush with the surface of the wood. You can use this method for wood flooring, furniture or anything else prone to cracking. Remember you can paint or stain the finished surface afterwards to make your repair invisible – just wait until it’s 100% dry first.
- To fix damaged furniture – Furniture demands some careful thought before you start. Firstly, are you mending the surface – a cosmetic repair – or a load-bearing part? The best product for surface repairs is a combination of thick and thin filler, with larger spots of damage needing thicker filler and smaller areas, a thinner product. To mend essential load bearing elements, a special
wood hardener rather than an ordinary filler is probably your best option.
- To fill gaps between boards – You can even fill large gaps between your floorboards and skirting boards. There’s a specialist product for this called
Bona Gap Master, available in a choice of popular colours including white and black as well as a load of natural-looking wood tones.
- Fillers that look like wood – When filling wood you need to ensure that the filler is 100% dry before staining or varnishing it. Filler gels are popular as they tend to keep repairs looking more like wood rather than a piece of white or coloured plastic. Filler gels work by mixing sanding dust, preferably from the wood being sanded and repaired, with a clear gel that binds the dust together. This forms a wood filler, that is partially made from real wood that can be stained, varnished or oiled. The thickness and consistency of the gel can be altered by adding more or less sanding dust, but the normal mixture is usually 50% gel to 50% sanding dust. Two popular filler gels that receive good customer feedback are Bona Mix and Fill and Fiddes Wood Filler Gel.

Practice makes perfect
There’s no reason why you shouldn’t do a few test runs on old bits of wood before tackling the real thing. The human brain is an amazing machine and it’ll soon build new neural pathways that make you more confident and competent. That way you stand the best chance of doing a great job.
Can I remove the filler once it’s dry?
Fillers are often harder than the wood itself. But you can remove them, and there’s some top guidance on the UK eHow site about how to do it.
