What’s the difference between Polyfilla and wood filler?

When you’re trying to fix holes in your wall, it can be confusing to know which product is best. Polyfilla, also known as plaster filler, has been around for over 100 years, but modern technology means there are now better options available.

However, there are times when you should use Polyfilla over other types of fillers or wood putty products – here’s what you need to know:

Can you use Polyfilla as wood filler?

No, you shouldn’t use Polyfilla as a wood filler. Wood filler is a better option for filling holes in your walls or fixing small cracks and breaks.

Polyfilla isn’t strong enough to hold up against the pressure of being used as a filler material and it can crack over time if it’s not applied as directed (with plenty of time to dry between coats).

Can wall filler be used on wood?

There are two main differences between Polyfilla and wood filler.

The first is that the texture of wall filler is finer than Polyfilla, which means it is easier to apply with a brush. This can make your job much quicker and easier if you don’t have much experience using either product.

The second is that wood filler has more strength than Polyfilla, making it better for fixing holes in wood surfaces like doors and window frames.

This makes it ideal for anyone who wants to repair small areas of damage but might not have enough time or money to use traditional methods such as sanding down the area before applying new coats (which would be needed with Polyfilla).

What works better than wood filler?

Polyfilla is a good choice if you have a small crack in your wall, but it also works well for filling larger holes.

Polyfilla is usually mixed with water before application, which makes it easier to apply than wood filler.

It’s also less expensive than other fillers, so it’s great if you’re on a budget!

If you want something that’s more like wood filler than polyfilla (and doesn’t require any mixing), consider using plastic wood instead.

Plastic wood comes in two different types: one that dries harder and one that dries softer. Both are easy to apply and can fill cracks or holes very well.

Another option is wood putty—which can be painted over after drying—but this material will not last as long as other fillers because it has less fiber reinforcement in its composition compared to the other products on this list above

What is wood filler used for?

Wood filler is used to fill holes and gaps in wood where it has been damaged or worn. It is typically used on furniture, doors, and windows. Wood filler is also popularly used to fill the cracks between floorboards.

Wood filler can be grey in color or white, depending on what type you buy. They are both equally effective at repairing wood; however, one does tend to dry much quicker than the other (the grey version).

Can you use Polyfilla on skirting boards?

Polyfilla is not suitable for filling holes in skirting boards. Instead, use a wood filler designed for this purpose.

Wood filler can be used on polyurethane painted wood and sealed wood, but it won’t adhere to polyurethane varnish or lacquer.

If you’re using an oil-based paint (such as dark stain) or varnish, stick with the polyurethane type of filler instead.

What can Polyfilla be used for?

  • Filling cracks in plaster
  • Filling holes in wood
  • Filling gaps between bricks and tiles, especially where there are gaps larger than 5mm.
  • Sealing holes in plasterboard, such as those that occur when you drill through it or screw into it.
  • Sealing cracks in plasterboard (you can use polyfilla to fill the crack and then scrape off the excess).

What is the strongest wood filler?

Polyfilla is the strongest wood filler and can be used to fill holes in wood, fill cracks in wood, fill gaps in wood, or fill gaps between your wooden surfaces.

Polyfilla is a two-part mix of plaster and sand that you add together and then mix with water until it’s the consistency of thick cream.

It dries hard as a rock within 24 hours. Polyfilla will not shrink or crack like traditional plaster does—it’s safe for use on both interior and exterior surfaces without being sealed afterward!

What to use to fill holes in wood?

Polyfilla is a plaster-based filler that can be used to fill holes in wood. Polyfilla is not strong enough to be used as a wood filler, but it is a great product for filling holes or cracks in walls.

Wood fillers are stronger than polyfilla and are best suited for fixing larger holes or cracks in wood. They can also be used to repair furniture with broken legs or other pieces of furniture that may have been damaged during transportation or storage.


We hope this article has helped you decide which filler to use. As you can see, there are many different types of fillers available on the market today, so it’s always best to do some research before making a purchase.
