How The DIY Works Team Tests & Rates The Wood Fillers

Over the years, we’ve carried out numerous repairs on wooden surfaces as well as multiple upcycling projects. This has meant that we’ve used a number of wood fillers in order to achieve the finish required.

Below is an example of where we tested a wood filler on a damaged oak door. This particular door was dropped and as you can see, it had chipped the oak in multiple areas. However, with the use of a wood filler (we used the High Performance filler by Ronseal), we were able to repair most of the imperfections. Unless you know what you are looking for, the damage to the oak is very hard to see and we would say the wood filler did a great job at repairing it.

As well as our experience of testing wood fillers on a range of surfaces, we also based our recommendations upon hours of research and a number of factors. Some of the factors that we took into consideration included the filling depth, drying time, ease of application, quality of the finish, compatible wood surfaces, size and value for the money.

The Best Wood Fillers

At DIY Works, our content is 100% independent and we would never recommend a product that we wouldn't use ourselves (read our editorial standards and how we test products).

1. Best Overall: Everbuild Multi-Purpose

(How We Review →)

By far the most popular and highly rated wood filler available in the UK is the Everbuild Multi-Purpose formula. It’s a ready mixed and easy to apply filler that’s ideal for all types of wood and can be used internally or externally.

Depending upon the finish you require, the brand offers this particular wood filler in light or medium stain, pine, white, light or dark oak, mahogany and teak. They also offer it as a high performance 2 part wood filler too.

Pros
  • Leaves behind a sandable surface
  • Non-flammable and minimal odour
  • Waterproof finish once dry
  • Dries within 60 minutes
  • Fills up to 5mm in depth
Cons
  • During our testing, we found that this wood filler took much longer to dry than other fillers we've tested

To conclude, the Everbuild Multi-Purpose wood filler ticks all the boxes in terms of its filling abilities, ease of use and value for money. You really can’t go wrong with this formula and it certainly won’t disappoint.

2. Best For Large Holes: Ronseal High Performance Wood Filler

(How We Review →)

The Ronseal High Performance is a wood filler that we have plenty of experience with (as shown in the condition of our tin in the top photo). Although expensive, it’s a professional grade formula that comes in a large 1KG tub.

According to the brand, it’s able to provide extremely tough repairs that won’t shrink or crack on any type of wood.

Pros
  • Provides unbeatable protection
  • Natural, dark or white finishes
  • Fast to dry (30 minutes)
  • Suitable for interior and exterior use
  • Fills more than 5mm deep (in layers)
  • Comes in a large 1KG tin
Cons
  • Most expensive filler within our roundup

If you are willing to spend a little extra, the Ronseal High Performance is the ultimate wood filler that’s ideal for any repair. Apart from the premium price tag, you won’t find a better filler that provides as good of a finish as this formula.

3. Best 2 Part: Roxil 2 Part Wood Filler

(How We Review →)

If you would prefer to use a 2 part wood filler instead of a ready mix formula, the Roxil filler is a great option to consider. According to the brand, it has excellent moulding, adhesive and sanding properties and it’s incredibly easy to use even if it’s your first time using a wood filler. It also benefits from being fast to cure with an estimated time of 30 minutes.

Pros
  • Easy to mix together
  • Styrene-free formulation
  • Suitable for interior or exterior use
  • Each tub provides a coverage of 220 cm³
  • Can be layered for larger defects in wood
  • Supplied with an applicator
Cons
  • Requires mixing out of the tin
  • Relatively expensive when compared to other fillers

Although expensive, the Roxil 2 Part wood filler is a high quality formula that provides a strong and long-lasting finish. The fact that it’s a 2 part formula also allows you to adjust the hardener to best suit your requirements too.

4. Best All-Rounder: Ronseal Multi-Purpose

(How We Review →)

Another wood filler by the Ronseal brand that’s far more affordable when compared to the High Performance formula is their Multi-Purpose alternative. It’s a ready mix filler that’s ideal for general wood repairs and dries in two hours.

Pros
  • Can be layered to fill large holes
  • Suitable for indoor or outdoor repairs
  • Once dry, it can be sanded, stained, screwed and nailed
  • Available in white, dark, medium and oak colours
  • Promises not to shrink or crack
Cons
  • Only available in small 250g tub (during testing, we went through this after a few repairs)

Overall, the Ronseal Mutli-Purpose is an excellent all-round option that promises great filling capabilities in a range of wood types. The only drawback is that the wood filler comes in a 250g tub and you may use it all up very quickly.

5. Best For Large Holes: Polycell Polyfilla For Wood

(How We Review →)

Polycell is a brand that is well-known for its standard wall filler but they also produce a filler for general wood repairs. It comes in a 380g tub and according to the brand, it fills up to 10mm deep in all types of wood.

Pros
  • Dries within 2 hours
  • Easy to sand down once dry
  • Flexes with the wood
  • Suitable for interior or exterior use
  • Can be nailed or screwed
  • Leaves behind a water resistant finish
Cons
  • After testing, we found that it started to go off within a couple of weeks (therefore you'll want to use it all up)

To conclude, the Polycell Polyfilla is a great option to consider because it works great on deep wood repairs and even light scratches. It’s also made by a brand that specialises in decorative fillers for complete peace of mind.

6. Best Value Runner-Up: Rustins Oak Wood Filler

(How We Review →)

Rustins are another reputable brand and they offer a number of wood fillers for each type of finish you wish to achieve. These formulas include an oak, natural, mahogany, teak and white finish but the brand’s most popular type is the oak filler as shown above. In terms of its filling capabilities, it can be used on softwood, hardwood, MDF and even plasterboard.

Pros
  • Can be painted, stained or varnished
  • Flexes with the wood
  • Easy to sand
  • Suitable for filling a range of surfaces
Cons
  • Can take up to 2 hours to dry

Although not as popular as many of the alternatives above, the Rustins Wood Filler is highly effective at filling cracks and holes in oak. The brand also offers a variety of other finishes to best suit your filling requirements too.
