If you’re looking for a waterproof wood filler, you’ve come to the right place. Luckily, we can help! While there are many types of wood filler on the market today, DAP plastic wood filler is one of the best because it’s easy to use and can be used for many things around your home. We’ll cover everything from what wood filler is to how it’s different from putty below:
Is DAP plastic wood filler waterproof?
DAP plastic wood filler is not waterproof. In fact, it should not be used around or near water at all. The best way to use it is to fill small holes and cracks in interior woodwork.
You can also use it in the same way as wood putty; however, plastic wood filler dries much more quickly than standard putties do.
If you need a waterproof solution for your project, be sure to choose one of the products listed above!

What is the difference between wood putty and wood filler?
Putty is a softer, more malleable wood product than wood filler. Putty is used for filling holes and other imperfections in wood. It can also be used to fill larger gaps in wood as well.
Wood filler is a harder substance than putty, and it will not compress when you press it into your project as putty does. If you use the wrong kind of material on your project and then try to sand or paint it, the softened material may crumble away instead of staying attached to the board where you applied it.
What can I use to coat wood to make it waterproof?
To make wood waterproof, you have a few options. The best way to waterproof wood is to apply a wood preservative or waterproofing stain.
A wood preservative will protect your deck from rain and snow, as well as other sources of moisture like standing water or rainwater that seeps into the cracks between boards.
If your deck was built with pressure-treated lumber, you should use an oil-based treatment; otherwise, opt for an acrylic-based or urethane treatment.
If you want to avoid using chemicals on your deck but still want it to be impervious to water damage, consider using a natural alternative: Beeswax and linseed oil!
These products create an invisible protective shell over the surface of your deck so it doesn’t absorb moisture from its environment. To waterproof a piece of furniture made from solid oak with beeswax and linseed oil all at once (and save yourself some time), follow these steps:
- Apply 1 coat of boiled linseed oil (or Danish Oil) on each side of the piece first before applying any waxes; this will let them soak in deep into the wood grain so they won’t flake off later when rubbed against anything else. Then brush one side at a time with 100%-pure white carnauba wax diluted 50/50 with mineral spirits until dry enough not to leave fingerprints behind when touched gently by hand – don’t rub too hard though because this can cause small scratches which would prevent full penetration into those areas next time around (if needed).
What to use to fill holes in exterior wood?
- Wood filler, when applied correctly, is an effective way to fill and repair holes in wood. In order to ensure that the wood filler you use will actually be waterproof and not cause future problems down the road, there are some things you should look for:
- Look for a wood filler designed specifically for exterior use. These products have been formulated specifically with the needs of outdoor applications in mind—they won’t shrink out of shape or crack when exposed to moisture (like this one).
- Don’t choose a thick formula if you’re working on an exterior surface; it’s better to err on the side of thinner consistency when filling holes on an outdoor deck or fence. Thicker formulas may expand too much once applied and create unwanted gaps between boards where water can get into your structure through cracks caused by swelling.
Can Plastic Wood filler get wet?
- Plastic wood filler can get wet and stay that way for a long time, however, it’s not recommended to use it outside in the elements.
- Plastic wood filler will expand when it gets wet, so if you need to fill a hole or crack and then paint over it within a few days, this probably isn’t your best bet.
Can DAP plastic wood be used outdoors?
It can be, but it would be better if you used a waterproof wood filler. Plastic wood is not waterproof and will warp and crack if exposed to moisture.
However, plastic wood can still be used in outdoor projects as long as it’s protected from water damage by being painted or sealed with a clear varnish or polyurethane.
Which is the best wood filler?
DAP Plastic Wood Filler is the best wood filler for waterproofing. This product has a flexible formula and can be painted, making it an ideal choice for filling cracks and holes in wood.
It is also easy to sand, allowing you to create a smooth finish after the filler dries. In addition, this product can be used on any type of wood including oak, pine, or redwood.
Can you use caulk instead of wood filler?
While it is tempting to use caulk as a substitute for wood filler, it is not a good idea. Caulk is not waterproof and will eventually crack or peel away from the surface you are applying it to.
While wood filler takes some time and effort to apply, it will fill in holes and make them look smooth once dried.
Caulk simply does not do this as well—it doesn’t have enough “grip” on surfaces like drywall or plasterboard so may pull away when dry if not applied correctly (and even then can sometimes come off).
Also, caulk tends to be significantly more expensive than wood filler which makes using caulk a bad choice overall!
It’s easy to find wood filler that is waterproof, but it’s also important to know how best to use this product.
It can be used outdoors and around pools or ponds, but you should make sure that whatever surface you are using it on is well sealed first.
