can you use Ronseal wood filler without hardener?

To be honest, I’m not sure why anyone would ever try to use wood filler without a hardener. Why would you want to make your life more difficult than it needs to be?

The short answer is that you don’t have to use a hardener with Ronseal Wood Filler and the long answer is that I’ll get into below.

What happens if you use wood filler without a hardener?

If you choose to use wood filler without a hardener, there are some things that may happen. In some cases, the wood filler will be hard to sand down and paint over.

This means that it will take longer for you to get rid of any marks or dings on your wood furniture when using this product.

You’ll also find it more difficult to glue other pieces of furniture onto the piece you’ve just filled in because the material won’t be as strong as if you had used a product with hardener added.

Finally, because there’s no chemical reaction happening between the filler and baseboards or other surfaces (as there would be with a product containing hardener), they won’t bond together as well or last nearly as long as they would have otherwise.

Do you need to use wood hardener?

No, you don’t need to use a hardener with Ronseal wood filler. The product has been manufactured so that it needs no additional ingredients in order to work properly.

If you do want to use a hardener, however, then you can add this in at the end of the process if you wish.

All you need is a few drops and then mix well before applying the filler over your damaged surface or hole.

This will make sure that your repair lasts as long as possible without breaking down again due to water damage or other problems.

Now that we’ve covered how not using wood hardener affects how Ronseal works on its own (and similarly when combined with other products), let’s look at what makes this type of material different from its counterpart: putty!

What is non-hardening wood putty used for?

Non-hardening wood putty is used to fill holes in wood, gaps between wood and metal, cracks in wood, gaps between plastic and metal, and gaps between plastic and stone.

The non-hardening wood putty can also be used to fill a hole or crack that is too big for the filler but isn’t as deep as it needs to be filled with another material like epoxy resin (which will need a hardener).

How long does Ronseal wood filler take to harden?

As with any DIY project, the amount of time it takes for your Ronseal wood filler to harden depends on a number of factors. The most important factors are temperature and humidity.

If you’re working on a hot day outside in the sun, you’ll need to wait longer than if you were doing it indoors in the winter.

Also, if your room is very dry or has poor ventilation (for example, if it’s next to an air conditioner or furnace), then it will take longer for your Ronseal wood filler to dry properly than if there was good air circulation in your home.

The last thing that impacts how long Ronseal takes to dry is what type of wood filler you choose: oil-based or solvent-based? Solvent-based fillers tend to start off slightly faster but also have more toxic vapors when drying because they emit volatile organic compounds (VOCs) which can cause respiratory problems when inhaled over long periods of time; oil-based fillers don’t have this issue but may stain light-colored surfaces like trim boards or furniture.

Why does my wood filler keep cracking?

You’ve followed the instructions on the packaging and applied your wood filler, but it keeps cracking. What gives?

There are a few reasons why your wooden repairs could be cracking:

  • Not enough filler—if you try to fill in a large crack with one dollop of filler, it won’t stick very well. It will be prone to cracking later on as moisture gets into the wood and expands. So apply several thin layers instead of one thick layer when filling in cracks or nail holes.
  • Too much filler—it’s also important to realize that applying too much wood filler at once can lead to problems down the road if it doesn’t have time to dry out properly first. If there is excess wetness left in the wood after application, it can cause contraction which leads directly back into our first point about not enough drying time before applying new coats of wet mixture (or even just plain old water). This can make it difficult for future coats of primer or paint due to both its thickness and lack of adhesion properties once dried out properly again

Does wood filler strengthen wood?

Wood filler is a cosmetic product that fills in the gaps in wood. It’s an excellent way to make old or damaged wood look like new, but it doesn’t strengthen your project.

Wood fillers are used for various reasons. Sometimes, homeowners want to cover up dings and holes in wood furniture or floors; other times, they want to remove unsightly cracks and creases from walls.

But despite their extensive uses and applications, they won’t change the structural integrity of whatever you’re working on.

If you have a large crack that goes through multiple layers of your wallboard or flooring (and you’re not sure what’s causing it) it may be time for some serious repairs instead of trying to mask things with something like this product!

Can you put a wood hardener on wood filler?

You can put wood hardener on wood filler, but you might not want to.

The most important thing to remember is that when you put wood hardener on wood filler, it’s like putting peanut butter on a sandwich that already has jelly on it.

You’re basically just adding extra ingredients and making the whole thing grosser in the process. If this sounds like something you’d be into, go for it!

But if you’re looking for something more robust or even just plain old delicious (or if you have any sort of dietary restrictions), then maybe consider another method for finishing your project.

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

Putty is a filler and filler is a putty. That may sound like an obvious distinction, but it’s important to know the differences between these terms when shopping for new woodworking supplies.

Putty and filler are two different products that perform similar functions: filling holes in wood. But they don’t do this exactly the same way.

Wood putty typically contains more clay than filler, so it has less plasticity than its counterpart—you can’t mold it into any shape you want like you can with wood filler.

Instead, you’ll need to use your hands or other tools (like a knife) to apply the putty into cracks or holes before smoothing it out with your fingers or another tool of choice until no visible gaps remain in your project surface.

Wood putty also tends to be more flexible than its counterpart; consequently, some people prefer using this material for larger areas since it doesn’t have as much of an impact on their work pieces’ overall strength as applying too much force during application could make them significantly less durable over time.


If you’re wondering whether or not wood filler will work for your project, remember that it all depends on what kind of wood filler you’re using.

If you don’t want to use a non-hardening version of the product because it’ll take longer than normal (and possibly weaken the wood), then there are other options like epoxy resin which can be set up in just an hour or so – perfect if time is tight!
