What is the best medium to thin epoxy resin?
Acetone and thinners are the most widely used mediums for thinning paints and other mediums. This is because their formulas are designed to strip away at the chemicals found in paint and adhesives. This is also what makes them a popular choice for those looking at how to thin epoxy resin.
How to soften epoxy resin?
One way to do this is to add some hot water to your bathtub or basin and place the bottles in there to soften. You should leave them in there for up to 20 minutes, based on the temperature of the water. This will loosen and thin your epoxy resin and hardener allowing for a smoother application. The only downside to heating is that it can make your products dry quicker.
How much epoxy to mix to make epoxy stronger?
This makes them weaker and much less durable than simply applying your epoxy direct to the area. When using this method, we recommend mixing the solution at a thinning ratio of ten to one. So you would add one part of your chemical to around ten times your epoxy resin amount for the best results.
How to apply epoxy resin to wood?
If you are working with any type of wood or wooden surfaces, then heating this surface before applying the epoxy resin is the best way to go. Applying your resin to a heated surface will cause it to thin so you can spread it easier. This way, as the wood contracts and cools down, the epoxy can dry and be absorbed into the fibers of the wood. Always try to have everything set up and prepared before you add the epoxy, as once it touches the warm surface you will need to work quickly before it hardens. To heat your surface a hairdryer or heat gun are both great options.
How hot should epoxy be to thin?
The key to both of these methods on thinning epoxy is that your substance or materials should never exceed 35 ˚C. They should always be warm and not too hot to touch. If you go over this heating temperature, it can cause your resin to dry too quickly.
Does thinning epoxy resin damage it?
Should you decide to try this method here are some disadvantage you may want to know beforehand: Thinning epoxy resin with chemicals will damage its durability. It will eliminate the water-resistant qualities of your adhesive. Solvents will also add to the cure and dry time of your resin.
How to thin epoxy?
To thin epoxy, you must first transfer it into another container and add one-tenth paint thinner to the transferred quantity. You should then stir it with a stick-like utensil that you don’t plan to use later. After the thinner has vanished into the epoxy, you can work with the resin as intended.
Why do you need to thin epoxy?
You will need to protect your epoxy from bubbles, dust, and pets or kids for a longer time when you operate with thin epoxy. If the reason you want to thin epoxy is that it traps bubbles when you leave it to cure, then you’re thinking along the right lines.
How many reviews does Sunnyside epoxy thinner have?
Given the appetite for epoxy products, it makes sense that this much-needed thinner has over 1,900 reviews and ratings on the site, with most of them positive. The collective rating of Sunnyside Epoxy Thinner is 4.5 out of 5 stars. A great average for that many reviews.

What happens if you use the wrong epoxy thinner?
When you use the wrong thinner, you can end up with a sludge that never cures.
What is the best diluent for epoxy?
The right diluent is an alcohol-based one, ideally a paint thinner. These thinners have construction-grade resilience, so they are reliable additions to the epoxy.
Can you pour epoxy without thinning?
It is worth remembering that pouring thinner first is not an option as thick epoxy can easily form a layer over it and keep your stirrer from reaching the diluent when you try to stir it. Always pour epoxy first. If you want to skip the steps above and make epoxy easy to pour without thinning it, then you should get comfortable working in very hot environments.
How to thin epoxy resin?
This method is not popular as the solvent method, but it can thin the epoxy resin, without weakening it. You can do this process by applying heat to the surface before applying the epoxy. The heat will thin down the epoxy to a workable size. A good example that can be used to see how heat works on a resin is canned cake frosting which is originally thick, but when it is heated it becomes thin and easy to pour.
How to make epoxy resin thinner?
If you want to try the heating method then you should start by filling a bathtub/bucket with hot water, preferably boiling water. Place the can of the resin inside the boiled water. Leave it to sit for a short while. The epoxy resin will become thinner because of the heat of the water which conducts effectively with metal. Apply the resin quickly before it cools down to its normal state.
Why is epoxy hard to apply?
However, the thickness and viscosity features of epoxy can pose problems. These features make it hard to apply epoxy. Thus, bad coverage causes the resin to cure improperly by creating pockets of air. The solution to this problem is to thin the epoxy resin.
Can you thin epoxy with heat?
However, thinning epoxy with heat should be done with some caution. This is because epoxy cures quite fast, so you need to organize your things first before you do the mixture of the hardener and resin. Choose a slow hardener like a 206, 207, or 209.
Is epoxy resin hard to apply?
You should adhere to instructions since you will be dealing with polyoxides. The only troublesome thing about epoxy resin is its thickness and viscosity, making it hard to apply . Thus, also preventing it from getting into the dings and nicks of the surface. This article will enlighten you on how you can fix this problem with much ease.
Can you use paint thinner to thin epoxy?
You can use acetone or paint thinner interchangeably to make epoxy thinner. However, exercise a lot of caution when doing this process because these solvents can weaken the epoxy resin. Moreover, if you mix the substances incorrectly the finished product will be ruined. So be sure to follow the general rule of thumb by mixing the thinner at a ratio of 10:1. This means that one gallon of acetone is enough to thin 10 gallons of epoxy.
Is epoxy resin a strong material?

Is acetone the same as paint thinner?
Paint Thinner or Acetone. Paint thinner and acetone are relatively the same with very minute differences between them . It is for this reason that they are interchangeable for the purpose of thinning out epoxy resin.
How to thin epoxy?
Whereas heating epoxy can enable you to maintain the original epoxy characteristics, adding a solvent such as acetone, lacquer thinner or denatured alcohol can create drastic changes. We do not recommend thinning epoxy with solvent at any time, and here’s why: 1 Adding 5% lacquer thinner to epoxy reduces epoxy’s compressive strength by 35%. As such, it’s no longer suitable as a structural adhesive. 2 Adding a solvent can extend curing time, making your work unpredictable. 3 Adding a solvent can cause the epoxy to shrink and crack over time. This happens if the solvent doesn’t evaporate before the epoxy hardens, but then finds its way out of the mix over time. 4 Adding a solvent such as acetone can change the colour of cured epoxy. 5 Adding a solvent can damage substrates such as Styrofoam – so test your solvent on your substrate before thinning your epoxy. 6 Adding a solvent can increase the risk of fire and damage your health. 7 Adding a solvent to wet out fibreglass quickly can create resin-starved fabric if excess epoxy drains out of vertical surfaces.
What does 5% lacquer thinner do to epoxy?
Adding 5% lacquer thinner to epoxy reduces epoxy’s compressive strength by 35% . As such, it’s no longer suitable as a structural adhesive.
Why does epoxy shrink?
Adding a solvent can cause the epoxy to shrink and crack over time. This happens if the solvent doesn’t evaporate before the epoxy hardens, but then finds its way out of the mix over time.
Does epoxy cure faster at room temperature?
A heated mix of resin and hardener does retain all the characteristics of epoxy cured at room temperature but it cures faster, which can catch people out. Using WEST SYSTEM 206 Slow Hardener® or WEST SYSTEM 209 Extra Slow Hardener® can help with this, as these two hardeners have a slow cure speed which gives you more time to work with the heated epoxy.
Does epoxy need to penetrate wood?
The technical staff at West System International often speak to customers who believe that epoxy needs to penetrate deeply into wood to be effective. Although that can be the case, most of the time it’s not necessary, which means often customers are thinking of thinning epoxy when it might not actually be beneficial.
Does epoxy thinning regain strength?
When it comes to rotten wood, although thinned epoxy certainly makes it harder, it doesn’t regain its original strength. If you’re thinking of thinning epoxy for any of these reasons, you need to be aware of the possible implications and whether it is strictly necessary.
Can you heat epoxy?
There are two options if you want to use heat to thin epoxy. You can heat the resin and hardener components separately and then mix them together to create a thinned epoxy; or you can heat the substrate – such as wood – and apply your room-temperature resin and hardener mix to the heated surface.
How to thin epoxy?
You have two options if you want to thin epoxy using heat. You can heat the resin and hardener components separately and then mix them together to create a thinned epoxy. Or you can heat the substrate – such as wood – and apply your room temperature resin and hardener mix to the heated surface.
How to coat wood with epoxy?
But if you’re coating wood, the best method is to warm the wood, rather than the epoxy. Remove the heat source just before applying epoxy and the mix will thin as it comes into contact with the wood. As the wood cools, the epoxy is then drawn in deeply before gelling, as the air in the wood fibre contracts.
Why does epoxy shrink?
Adding a solvent can cause the epoxy to shrink and crack over time. This happens if the solvent doesn’t evaporate before the epoxy hardens, but then finds its way out of the mix over time.

Using WEST SYSTEM 206 Slow Hardener ® or WEST SYSTEM 209 Extra Slow Hardener ® can help, as these two hardeners have a slow cure speed giving you more time to work with the warm epoxy.
Is epoxy good for wood?
A neat epoxy coating on the surface, for example, provides far better water resistance than thinned epoxy , because thinned epoxy tends to become porous. Similarly, adhesion depends on the surface area of a joint, the strength of the wood and the strength of adhesive used and not – as many believe – on deep penetration of epoxy. And when it comes to rotten wood, although thinned epoxy certainly makes it harder, it doesn’t regain its original strength.
Does epoxy penetrate wood?
The technical staff at West System International often speak to customers who believe that epoxy needs to penetrate deeply into wood to be effective. Although that is sometimes the case, most of the time it’s not – and customers are thinking of thinning epoxy when it might not actually be beneficial.

How to thin epoxy?
To thin the epoxy by heating, use a hairdryer. You can also put tubes of epoxy in the microwave. Ten seconds should be enough; take the tops off first so they don't overflow. If you choose to thin the two-part epoxy with a solvent, think about whether it is necessary first.
Can epoxy be thinned?
For certain, the epoxy will be weakened if thinned, whether you are using a special coating or glue. Strength and impermeability are the desired qualities in two-part epoxy, and these will be degraded since the solids in the resulting mixture will be sparser. Advertisement. To thin the epoxy, once the components have been mixed, ...
Is epoxy easy to apply?
Often, an epoxy is easier to apply than you might anticipate, so test it prior to thinning. Also, even though it might not seem that you are getting the penetration into the surface that you want, it is likely that the product is working fine and might not work if it is thinned.
Can epoxy be used as a coating?
A question to ask prior to thinning with a solvent is if you really need to. Often an epoxy, when used as a coating, will penetrate wood or concrete sufficiently without any dilution, ...
Does epoxy thinning solvent evaporate?
It is important that the solvent you use to thin the epoxy will evaporate completely and fast, so that it does not remain in the epoxy when it dries, potentially weakening the bond further. The rule of thumb when thinning is that a little goes a long way.
Step 1 – Start with Half The Amount of Resin
Step 2 – Add One Part Paint Thinner For 10 Parts of Epoxy
- This one is a straightforward step that people get wrong only because they try to aim for a total of ten. A simpler method is to simply divide the amount of epoxy by ten and pour that much thinner. So, let’s suppose you want 1 gallon of epoxy for the project, and you start with half to be safe. Dividing 0.5 gallons of epoxy by 10, you get 0.05 gall...
Step 3 – Stir Using An Appropriate Utensil
- This is dictated entirely by how big a project you have on your hands. If you’re working with a cup’s worth of epoxy, you can use any spoon you plan to throw away later. But it is also possible that the project you’re working on will encompass your entire floor. In that case, using an entire shovel to mix the epoxy in a barrel will make more sense.
Step 4 – Lay The Epoxy
- Yes, the next step isn’t to repeat the same steps with the rest of your epoxy even though you currently have only half the thinner. This step helps keep your epoxy from curing at an inopportune time. Work with the half that you have thinned and return to the remaining epoxy when you’re done with this. In some cases, you do need the entire batch in one go, which is where flipping this ste…
Step 5 – Thin The Rest of The Batch
- Using the same ratio and steps outlined in steps one through three, then the remaining batch, so you have enough epoxy to finish your project. Once the epoxy is thinned, proceed with the project as intended. It is worth remembering that pouring thinner first is not an option as thick epoxy can easily form a layer over it and keep your stirrer from reaching the diluent when you try to stir it. A…
Final Thoughts
- Thinning epoxy isn’t rocket science but requires the same seriousness as working on a rocket. Spilling too much thinner can drag the cure time, while using the wrong diluent can ruin your epoxy batch. Follow the steps in the post above (or recapped below) to do this right. 1. Add epoxy to a different container 2. Add one-tenth of the same amount of thinner into the same container …
