are wood filler fumes dangerous?

Wood filler is a great way to fix up your wooden furniture, but you may wonder if it’s safe. Wood filler can be toxic if you don’t use it properly and it’s important to know what the risks are before using any wood filler product.

In this article, we’ll look at how to use wood putty safely, as well as its potential health risks and how best to avoid them.

Is wood filler toxic?

Wood filler is not toxic. It is made of wood, which is not toxic.

Wood filler is not a chemical. Before you ask: no, the wood glue that you use to attach two pieces of wood together isn’t a chemical either—it’s just glue!

Wood filler doesn’t have any active ingredients that are dangerous when breathed in or touched (although it may irritate skin).

How long do Bondo fumes last?

Bondo is a two-part epoxy putty that hardens in 24 hours and is toxic to breathe in. It contains two parts: a hardener and resin.

  • The hardener reacts with the resin to create an extremely strong bond that can be sanded and painted.
  • Bondo dries within 24 hours, but it’s recommended that you wait for at least 48 hours before sanding or painting over it because this will give time for any bubbles or air pockets to rise above the surface of your project.

Is Bondo safe to use indoors?

Bondo® is considered non-toxic and non-corrosive to the environment. It also does not contain any hazardous ingredients that could be harmful to humans or pets.

Bondo® wood filler has been tested by independent laboratories and found to be free of asbestos, crystalline silica, and other compounds are known to cause lung disease in humans.

This means that there is no need for protective gear when applying Bondo® products in your home or garage as long as you follow all safety precautions during application such as wearing protective gloves, goggles, mask, and/or respirator depending on your level of exposure risk.

What happens if you inhale wood filler?

If you inhale wood filler, your symptoms may include coughing, difficulty breathing, and headaches. These symptoms can happen immediately or several hours after exposure to the fumes.

The severity of these symptoms varies based on how much of a dose of the pollutants you take into your lungs.

Long-term effects of inhaling wood filler include permanent respiratory damage such as asthma, bronchitis, and emphysema.

If you continue to breathe in high levels of these harmful gases over time (even if it’s not every day), they could cause serious health problems including death due to respiratory failure or lung cancer.

What’s the difference between wood putty and wood filler?

Wood putty is a finer-grained material that’s used to fill in small holes and cracks, while wood filler is thicker and meant for larger gaps.

Although it’s easier to apply than wood putty, wood filler can sometimes be difficult to level out. Wood putty tends to dry faster than wood filler as well, which means it’s easier for sanding dust to stick on the surface of the wood if you use a power sander without proper ventilation.

Wood putty tends to be less expensive than wood filler, but they’re both made from similar materials—usually cellulose fibers or synthetic resins.

How long does wood filler take to dry?

Wood filler typically takes 24 hours to fully cure. If you want it to dry faster, you can use a heat gun or hair dryer on the low setting.

Alternatively, you can let the filler sit overnight and then sand it down in the morning. It’s up to you how much time you want that extra day of drying time versus how much longer it will take for your project (and whether waking up early for the second day of work is worth it).

What is Ronseal wood filler made of?

Ronseal wood filler is made from a mixture of wood flour, linseed oil, and a few other ingredients.

The key ingredient which gives Ronseal its unique properties is linseed oil (also known as flaxseed oil), an essential oil extracted from the seeds of flax plants.

It has been used for hundreds of years in many applications such as paints and varnishes.

When mixed with water and applied to damp surfaces it helps the treated area dry more quickly than untreated surfaces would do alone – this makes it very useful at home when you’re trying to fix something quickly!


It’s important to use safety precautions when using wood filler, especially if you’re using it indoors. You should avoid inhaling the fumes and make sure you’re not working in an enclosed space without adequate ventilation.

We hope this article has answered all your questions about whether or not wood filler is safe and how long it takes for Ronseal Wood Filler to dry!
