Why has my resin gone soft?

If you’re new to resin, then it’s normal to be confused about what will happen when you use it. If your resin isn’t hardening as fast as you’d like or if it’s not drying at all, then this guide is for you!

We’ll walk through some common reasons why resin might get stuck in its liquid form and give you tips on how to fix these problems so that they won’t happen again.

What do you do if your resin is soft?

If your resin has gone soft, there are a few ways to dry it out.

  • Use a hair dryer to dry resin.
  • Use a heat gun to dry resin.
  • Use a heat lamp to dry resin.

Why has my resin not gone hard?

If your resin has not gone hard, it may be because:

  • You had too much water in the resin. You should always mix your resin in a well-ventilated area, and never use more than 10% water by volume.
  • You had too much hardener in your resin. The same applies to hardeners as it does to water–never add more than 10%.
  • You had too much catalyst in your resin. The same rule applies here–never add more than 10%.
  • You mixed the wrong ratio of hardener and catalyst when mixing them with the base material (resin). The proportions need to be precise for this step, so make sure you follow the recipe exactly (and don’t forget how much you put into each container!).

Can you dry resin with a hair dryer?

You’ve tried all the tricks listed above, but your resin still hasn’t dried. Can a hair dryer help?

Generally speaking, no. A hairdryer is too hot and too forceful to be used on resin. The heat from a hairdryer will cause bubbles in your resin, which means it won’t cure properly.

However! There are some instances where using a hairdryer works just fine for curing resin (and even better than an oven).

And if you’re looking for a way to speed up the process of curing your castings with more traditional methods—like an oven or microwave—then using a hair dryer may be useful as well.

What happens if you use too much hardener in resin?

If you add too much hardener to your resin, the result will be a stiff, brittle material. This is because the hardener has reacted with all of the reactive groups in your resin and there are no more free ones left to react with each other.

If you add too much hardener to your resin, it can set too quickly and become brittle or inflexible as it dries. There are many factors that contribute to this problem and if this happens to you, try adding a little more of some other additive like an accelerator or retarder until you find what works best for your situation.

How do you fix epoxy resin that won’t dry?

If your epoxy is too thick, try adding more resin. If it’s too thin, add some hardener. Your goal is to make the mixture as close to a 50/50 mix as possible.

The best way to get there is by trial and error (and basically just adding a bit of something at a time). You can also use our handy chart below:

  • If you have too much hardener, use less epoxy resin.
  • If your mix has too much epoxy resin in it, add more hardener.

How do you harden sticky resin?

  • Hair dryer

You can use a hair dryer to dry out the resin if it has been in contact with water or moisture, which is why this method is most commonly used by people who have resin that has gone soft after being exposed to their project’s ambient temperature for an extended period of time. To harden sticky resin using a hair dryer:

  • Plug in your hair dryer and set it on its highest setting (you’ll want to use the lowest heat setting possible).
  • Hold your bottle of resin upside down over any source of fire—like a candle flame or lighter—until it melts into a liquid state again.
  • Dip your brush into this liquid form of the material and apply it directly onto whatever surface needs fixing (you may want to practice this technique first).

How do I make resin harden faster?

There are a number of strategies for making resin harden quicker. Some of the most popular include:

  • Use a hair dryer to heat the area where you’ve laid down the resin.
  • Use a heat gun or similar tool to gently warm up your resin.
  • Using a heat lamp or light box as an alternative to direct heat sources (such as those mentioned above). Try placing it at least 6 inches away from your piece and watch how quickly it starts to cure!

If you’re looking for something more high-tech than these options, there are also products available that can speed up the curing process using infrared technology.

If you’re feeling brave enough to try one out yourself, try using something like this propane heater instead of traditional methods—it’s worth noting that these heating tools will cost more money upfront than other methods but they’ll save time in the long run by speeding things along quite nicely!

How do you dry resin in cold weather?

Drying your resin in cold weather can be difficult, but there are a lot of different ways to do it. You can use a hair dryer on high heat and direct the hot air onto your piece.

This will help dry out any moisture that may still be trapped in your resin. If you don’t have access to a hair dryer, consider using a heat gun instead—this will work similarly but can also be used as an option for drying parts that aren’t quite ready yet (because they’re still curing).

If neither of these options is accessible or practical for whatever reason, consider using a heat lamp instead—or even better yet: two heat lamps! Heat tents designed specifically for resin curing are also available online from companies like Lexx Labs; this tent comes with an integrated heating element that covers all surfaces inside it and prevents drying times from being affected by temperature fluctuations outside of it.
