1. Quick Drying

Bondo is used for projects both indoors and outdoors. Drying time is a vital factor that determines a lot of things. The 3m Bondo wood filler gives you control over the drying time because it comes with a hardener. You can regulate the drying time by controlling the hardener par part that you will add to the filler.

Bondo filler takes about 5 to 7 minutes before drying up completely. Therefore, you have that much time before you finish the other flaws and start working on the filler. You can use a thicker consistency for deeper holes to increase the drying time. The filler comes with the versatility that you need when working with wood.

Bondo is made for both indoor and outdoor use. However, when working outdoors, the chances of the filler drying faster are higher because of wind and other factors. The dry time will largely depend on the consistency of the mixture and the environment you are working in.

2. Water Proof

Some wood projects are meant for outdoor purposes. Furniture, doors, windows, and other outdoor projects. The filler can be used confidently because it is water-resistant once primed or painted. Not every brand of wood filler is good for use outdoors, especially if it is water-based. Fillers mixed with water soak up moisture when left outdoors and might not be effective in the long run.

3. Strong

With Bondo, you will get value for your money. The professional carpenter's wood filler creates a strong bond on the wood surface, looking like real wood.

Wood repair is made easy with Bondo because it will fill holes left behind by nails and screws, leaving behind no traces of trauma or history on the surface of the wood.

The only downside to the strength of the wood filler is that it might not be easy to sand once the mixture is dried up. Try and sand within the first 15 minutes or at most 30 minutes after application. You will end up with a repair that looks like real wood.

4. Minimal Shrinkage

Unlike water-based wood fillers, Bondo has very minimal shrinking once applied. Whether used interior or exterior, the wood filler dries up fast, reducing the action time to only a matter of minutes. This gives the filler just enough time to dry without shrinking.

When you apply two layers on the surfaces you are working on, the filler dries up with the same mass as when you first applied it on wood.

5. Sanding

Natural wood is easy to sand as wood fibers come off relatively easily when exposed to abrasive materials. Bondo, however, is not the best wood filler for sanding. The wood filler dries up pretty fast and does not leave enough time for sanding if you are working with multiple holes or flaws.

Bondo dries up in a matter of minutes, between 5 to 7 minutes. Best wood fillers dry up fast, but it comes at a small cost of a more difficult sanding.

6. Odor

The odor would be the biggest downside of the wood filler. The odor tends to be very strong for the first one or two hours after applying the filler. After that, you can use the filler for both interior and exterior furniture but in a well-ventilated room.

Frequently Asked Questions about Wood Fillers

a) Can You Paint Wood Fillers?
