how to use Minwax wood filler?

Wood filler is a great way to fill in gaps on wood. It can be used to repair a hole or crack, or simply as a way to add texture and depth to your project. Minwax offers many types of wood filler, so it can be tricky to decide which one is right for you.

In this post, we’ll cover all the basics: what is Minwax wood filler? How do you use it? And most importantly, how long does it take to dry?

How long does Minwax wood filler take to dry?

The drying time of Minwax wood filler varies depending on the type of product you’re using and the temperature, humidity, and thickness of your filler.

As a general rule, it can take anywhere from a few hours to a few days for Minwax wood filler to dry.

If you’re using a putty-like consistency of Minwax wood filler, like oil-based or water-based products, they will dry out within 24 hours.

However, if you’re using a thicker product such as latex or polyurethane fillers (which are both water-based), then it may take up to seven days before they are completely hardened and ready for use again!

Is Minwax a good wood filler?

Minwax wood filler is a great wood filler that can be used for many different projects. It’s easy to use and dries quickly, which means that you don’t need to spend hours waiting for it to dry before moving on with your project.

You’ll also find Minwax wood filler easy to sand and stain because it sands down easily so that you have a smooth finish when it’s time for finishing touches.

Do you use wood filler before or after staining?

You can use it before or after staining.

If you’re working on an unfinished wood piece, or if you want to make sure that the stain doesn’t get absorbed into the wood and give it a darker color, you can apply filler first.

This will create a barrier between the stain and your project so that it goes on evenly and looks great!

However, if you’re working with stained pieces that are already finished but have some cracks in them, you may wish to wait until after they’ve been stained.

If this is the case then applying filler afterward is probably best because there’s already some paint/stain on top of those areas anyway – meaning there’s no need for another layer right now!

How long should you leave wood filler before sanding?

After you’ve filled the gap with wood filler, you can either sand it immediately or leave it overnight before sanding.

If your project is large enough that multiple coats of filler are needed, then it might be worth leaving the second coat for a day or two so that the first coat has had time to dry completely before applying the second layer.

Do I need to seal wood filler?

Yes, you need to seal wood filler. It’s not enough to just leave it as is; the filler needs something on top of it so that you can treat the area like any other part of your furniture.

The best way to do this is with primer before any paint or stain goes on.

Prime the wood filler with a coat of spray-on primer and allow it to dry completely before moving on to anything else.

The more porous your wood filler is, the longer this will take—you can speed up drying times by using a blow dryer or heat gun if necessary (just make sure not to melt any plastic parts).

You should also wait until all surfaces are dry before sanding them because some moisture may still be present beneath the surface which could cause problems later on when trying to stain or paint over them again (which would cause chipping).

How big of a gap can wood filler fill?

It depends on the size of the gap. Wood filler can fill a small gap if you use just enough to cover it. If you’re working with a larger gap, however, you may have to apply several layers of wood filler and let each layer dry before applying another one.

Can Minwax wood filler be used without a hardener?

  • Yes, you can use Minwax wood filler without a hardener. The main reason for using a hardener is that it helps the wood filler adhere to the surface of the wood better. If you want to use Minwax wood filler without a hardener, you will need to sand your surface before applying it because this will help give it something to bond with when drying.
  • Minwax Wood Filler is a water-based product so there is no need for thinning or other additives like solvents or oil-based products.*

Does Minwax wood filler Harden?

Yes, Minwax wood filler hardens. How long it takes to harden depends on the temperature and humidity. If you are in a cold climate, it will take longer than if you were in a warm one.

You can speed up the process by using a hair dryer or heating lamp for about 10 minutes, but be careful not to burn yourself or damage your furniture!

Minwax wood filler is great for filling large gaps or small cracks that are caused by water damage, which can happen when water gets behind the top layer of paint on your walls and causes mold growth underneath it (this happens more often than people think).


In general, you should apply Minwax wood filler to a rough or uneven surface. The filler will fill in any gaps and make the surface smooth again.

The best way to use Minwax wood filler is by mixing it with water on a rag or sponge until it becomes a paste-like consistency.

After allowing time for the mixture to dry completely, sand down any excess material using fine grit sandpaper before applying your desired finish product like paint or stain.
