What to use to fill holes in wood before painting?

If you’re planning on painting an interior wall or part of a wooden floor, you’re going to need to fill in any holes.

This is important because it makes the project look better and makes sure that the new paint job will last.

There are lots of different materials that can be used for this purpose, but what is best? We’ll take a look at all your options here!

What do painters use to fill holes?

When you’re filling holes in wood, it’s important to use the right filler. You should always use a filler that’s compatible with the paint you’re using.

  • Wood putty and wood filler are generally used on bare wood, but they need to be sanded after they dry before painting over them. If you don’t have time for this step, or because the area isn’t visible when your project is complete, consider using something else instead.
  • Spackling paste is another option for filling small holes in furniture or cabinets; however, it may not be as durable as some other options (e.g., epoxy). It also tends to shrink when drying so make sure you fill any cracks before applying spackling paste around them!

What to fill wooden holes with?

  • Use wood filler.
  • Use spackle.
  • Use wood putty.
  • Use a combination of all three, depending on the size and type of hole, as well as its location on the item you’re working with.

Should I use wood putty or wood filler?

If you have small holes in your wood and want to get them filled before painting, wood filler is a great option.

It’s hard enough to fill the hole without going into the wood, but if you’re working on larger areas that need filling, it may be wiser to use putty instead.

What is the difference between Spackle and wood filler?

Spackle is a plaster-based filler that is used to fill small cracks and holes in wood. Wood filler, on the other hand, is a putty-based filler that is used to fill larger holes or gaps in wood.

Spackle can be applied directly over even the most porous surfaces without concern for color change or discoloration.

Wood filler, however, may require multiple coats before it fully covers the surface of your wood item—and will result in some darkening of your project’s natural grain pattern (especially if you’re working with stained plywood).

Can I paint over wood filler?

Yes! You can paint over wood filler. However, unless the filler was designed to be used with paint, it is not recommended that you use paint on top of the filler.

Instead, sand away any loose material and then apply a fresh coat of primer that matches your color. It’s also a good idea to let it dry before applying additional coats of paint or varnish.

Should I fill holes before painting?

If you’re painting a light color over a dark one, it’s best to fill the holes first.

If you’re painting a dark color over a light one, leave out the filler and just sand them down after you’ve painted the rest of your piece.

How do you fill in before painting?

If you’re unsure of how to choose a wood filler, it’s helpful to keep these tips in mind:

  • Choose a filler that matches the color of your wood. This will help make sure your finished product matches, and it will be much easier to blend in with the rest of the piece.
  • Choose an easy-to-apply filler. Some fillers are too thick or hard to work with, so make sure yours isn’t! It should also be easy to sand once applied.
  • Make sure your filler won’t crack or shrink over time. If it shrinks during drying, it can look bad when painted over top of; if it cracks during drying (or later), then this makes painting more difficult as well as potentially leaving marks behind on your surface when painted over top of

How do you fill a gap before painting?

As a general rule, you’ll want to use a filler that’s the same color as your paint. However, there are some exceptions to this rule:

  • If your wood is lighter than the desired shade of paint, use a slightly lighter filler.
  • If your wood is darker than the desired shade of paint, use a slightly darker filler.
  • If you want to create an aged look for an antique piece of furniture or something similar (like the table in the photo above), choose either black or grey and apply it when dry over top of any other color you’ve chosen.


It’s important to know the right product for the job. Some products will be more suited than others, depending on what you’re trying to achieve.

For example, if you have a hole in your wall that needs filling before painting then it would be best to use wood filler or Spackle as opposed to just spackling paste because these products will give off fewer fumes when working with them which could result in less damage being done by inhaling toxic substances or even getting splinters from wood particles flying out at high speeds due to impact force when hitting hard surfaces such as concrete floors which could ultimately cause harm over time.
