does wood filler stick to plastic?

Wood filler is the most commonly used material when it comes to fixing and repairing wood objects. It’s easy to use, readily available, and affordable.

But what about using wood filler on plastic? Is that even possible? If you’re wondering whether wood filler sticks to plastic or not, rest assured because this article will give you all the answers!

What is the difference between Plastic Wood filler and wood filler?

You may have heard the terms “wood filler” and “plastic wood” used interchangeably. Both are putties that can be used to fill holes, cracks, and crevices. While they may seem similar, they’re actually quite different.

  • Wood filler is made of wood pulp and comes in a variety of forms—powders, flakes, chips, and pellets—and has been around since the 1930s. When mixed with water it becomes malleable so you can shape it into place easily (think: fingers). As it dries out though it hardens until you need another coat of something like paint or stain over the top if you want to cover up your repair job fully.
  • Plastic Wood is also made from cellulose but instead of coming from trees, it is derived from non-toxic materials like recycled newspapers or reclaimed cardboard boxes! The consistency is similar too as both will dry out after being exposed to air for a while but can still be shaped into place while wet (though Plastic Wood won’t hold its shape forever).

How do you fill holes in Plastic Wood?

  • First, use a putty knife to apply the filler.
  • Next, fill the hole as much as possible and let it dry for 24 hours, then sand with fine-grit sandpaper (150-grit). This can be done by hand or using an orbital sander if you have one available to you.
  • Finally, paint over your wood filler with whatever color you want to achieve!

How strong is Plastic Wood filler?

Plastic Wood filler can be used for a variety of projects. It can be used to repair holes, cracks, and other damage to the plastic. It can also be used for filling gaps, filling joints, or filling gaps between plastic and wood.

Does Plastic Wood adhere to wood?

  • If you want to use Plastic Wood to repair wood, you must first sand the wood to create a rough surface.
  • Once this has been done, apply Plastic Wood according to the instructions on its label (usually by brushing it onto your desired area).
  • The end result should be that it does stick pretty well.

Is it better to use wood filler or caulk?

Caulk is for sealing, and wood filler is for filling. You can use caulk on most surfaces, but it won’t last as long as wood filler if you’re looking to fill in a hole in your floor or wall.

Caulk also doesn’t stick very strongly to plastic; while this may seem like an advantage at first, it actually makes caulk more likely to come off over time.

Wood filler sticks better and lasts longer than caulk does when used on plastic surfaces like pipes or door knobs because of its adhesive properties.

How big of a gap can wood filler fill?

Wood putty can fill the same size gaps as a wood filler. However, it doesn’t dry quite as hard and may be more difficult to smooth out later on down the line.

The main difference between them is that caulk is much thinner than either of them and doesn’t get as hard when it dries out.

This makes caulk ideal for smaller cracks like those in your walls or ceiling where you don’t want as much bulkiness visible in your patch job.

Plastic wood putty can also fill small shafts or holes in things like plastic chairs or cheap toys but isn’t recommended for larger areas like table legs because it may crack during use over time when exposed to moisture (such as rain).

What is the difference between wood putty and wood filler?

_Wood putty_ is a softer, more malleable material. It’s used to fill gaps and holes in wood furniture and other wooden surfaces.

Wood filler_ is a solid material that comes in tubs or bags; it’s good for filling deep holes or gaps in wood.

Wood putty is ideal for filling small holes; it can be applied with your fingers or an applicator stick (like a toothpick). Wood filler can also be used to fill small holes but should not be used as an adhesive.

How long does it take plastic wood filler to dry?

While it is possible to use plastic wood filler to repair your plastic dollhouse, you should be aware that the drying time will vary depending on the type of plastic wood filler you are using, the temperature and humidity, and other factors.

The best way to determine how long it will take your particular application of plastic wood filler to dry is by experimenting with a small piece first.


When wood filler is used, it’s best to test a small area before applying the filler to an entire surface. If you find that it does not adhere well, you can use a primer for plastic or vinyl surfaces.

This will help the wood filler stick better and make cleanup easier when your project is complete.
