Are your resin projects getting sticky? Not to worry, because in this article, we will explore expert techniques to rescue your projects from this unfortunate situation. Stick around to gain valuable insights and practical solutions to fix sticky resin. Let's dive right in!
Firstly, take a quick glance at your project and determine which type of sticky resin you're dealing with. Here is the table about common types of sticky resin (runny resin, tacky resin and soft spots on the surface of resin) and ways to fix it.

"Runny resin" is a common phenomenon in resin making progress. Several factors can contribute to resin becoming runny, and understanding these factors is crucial for achieving successful epoxy projects.
Runny resin has a thin and overly liquid consistency, which is thinner than desired. This can cause the resin to leak out of molds or project boundaries, resulting in a messy and uneven finish. Additionally, runny resin may not cure properly, leaving a sticky or tacky surface.
Some people will wonder why my resin is still sticky after finishing a project. Below are some ways that can cause the resin to be runny:
If you have runny resin, it is important to fix it before it cures. Otherwise, it will weaken the resin and make it more susceptible to damage.
Tacky or sticky epoxy resin is a common issue that can arise during the curing process. Several factors can contribute to resin remaining tacky after it's supposed to have cured properly. Here are some reasons and solutions for tacky resin:
Tacky resin is a common problem that can occur when working with epoxy resin. It is characterized by a surface that remains sticky or gummy, even after the resin has cured. Tacky resin can be clear or translucent, but it will lack the expected hardness and smoothness.
If you worry about why my epoxy is sticky, here are the reasons that can cause the resin to be tacky.
Why is my epoxy still sticky? Why is my resin not hardening? If you have sticky resin, here is how to make resin not sticky. You can apply one of these options.
Soft spots in resin can be frustrating, as they can ruin the look and feel of your project. There are a few things that can cause soft spots, but it's important to address them so that you can achieve a uniform and durable finish.
Soft spots in resin appear as areas with a different texture or consistency compared to the rest of the resin surface. These spots can feel gummy, flexible, or slightly soft to the touch, and they often don't have the expected hardness or clarity of properly cured resin.
“Why is my resin sticky after drying?” That’s the issue many people are dealing with. Resin can become soft due to a variety of factors, including improper mixing. When resin is not mixed properly, pockets of uncured or partially cured resin can form. These pockets will remain soft even after the resin has cured.
It's important to scrape the sides of the mixing container when you're mixing resin to ensure that everything is properly mixed. However, another reason of soft spot may result from scraping the sides of the mixing container when you pour the resin. Unmixed resin or hardener can get into your epoxy resin pour and cause soft or wet spots.
If you have soft spots in your resin, this is how to make resin harder:
2. Remove any sanding dust with a damp paper towel.
3. Gently scrape away any runny or gooey resin, taking care not to injure yourself. Leaving any wet material on the surface could cause it to leak out from under the new resin coat.
4. Make sure to scrape off all of the runny resin and sanding dust. Then pour a fresh coat of artResin which is measured and mixed carefully.
So, remember. If you are dealing with sticky resin, follow this note cause this is how to harden sticky resin
Here are 8 tips to avoid sticky resin in the first place. Following these tips will help you to ensure that your resin projects are free of sticky resin.
Moisture can interfere with the curing process of resin, causing it to become sticky. To avoid this, you should work in a dry and humidity-free environment, preferably with an air conditioner or a dehumidifier. You should also avoid working on rainy or humid days, or store your resin in a cool and dry place.
Temperature is another factor that can affect the curing of resin, as it can speed up or slow down the chemical reaction between the resin and the hardener. The ideal temperature for curing resin is between 75 and 85°F (24-30°C). You should also avoid exposing your resin to direct sunlight or heat sources, as they can cause the resin to overheat and become sticky.
Colorant is a substance that can add color and effects to your resin, such as pigments, dyes, paints, glitters, etc. However, adding too much colorant can also alter the chemistry of your resin and prevent it from curing properly.
To avoid this, you should add no more than 6% colorant to your resin mixture. You should also use colorants that are compatible with your type of resin and mix them well before adding them to your resin.
When pouring resin, avoid thick layers. You should apply thin layers (between ⅛-½” thick depending on the size of the mold) which can take from a few hours to a few days depending on the type and amount of resin you use. Then, wait for each layer to cure before adding another one.
Mixing your resin thoroughly is essential for ensuring a proper curing process and avoiding sticky resin. You should also mix them for at least 3 minutes, scraping the sides and bottom of your mixing container and stirring slowly to avoid creating air bubbles.
Clean and dry your mixing tools before and after each use to prevent resin buildup and ensure optimal results.
Instructions for cleaning your epoxy resin mixing cup:
The mixing ratio is typically 1:1 or 2:1, but always consult the instructions for specific details. Use graduated cups or other precise measuring tools to ensure you use the correct amount of resin and hardener.
Rushing the resin curing process can result in sticky resin, so let the resin cure for the full amount of time specified in the manufacturer's instructions. If the resin is still tacky after 24 hours, you can apply a thin coat of polyurethane spray to harden it. Let the polyurethane dry for at least 30 minutes to dry before applying a second layer. Be careful not to apply too much polyurethane, as this can cloud the surface of the resin.
In conclusion, sticky resin can be a frustrating problem, but it is not the end of the world. There are multiple ways to fix sticky resin. And with the right techniques, you can keep your projects looking their best. However, the article also reminds readers about the importance of prevention as preventing sticky resin is better than fixing it.
Because stsicky resin can be caused by a number of factors, such as incorrect mixing ratio, improper mixing, cold temperature, dust, and water contamination, or not curing for long enough.
You can prevent stickiness by accurately measuring resin and hardener, following manufacturer instructions, and working in a dry, controlled environment. Remember, the key to preventing sticky resin is proper preparation and application. Always follow the manufacturer’s instructions when using resin.
Thin coatings of epoxy typically dry in 6 - 12 hours, but should be left untouched for at least 24 hours. And thicker coatings of epoxy may take 2-3 days to become tack-free. So the epoxy should be tacky from 12-24 hours.
No, sticky resin is not safe to use. It is a sign that the resin has not cured properly. This can make the resin weaker and more likely to chip or crack. It may also release harmful fumes. If you have sticky resin, you can try to fix it by sanding down the sticky areas and applying a new layer of resin, or by using a resin hardener.
Yes, you can speed up the curing process of resin to avoid stickiness. However, speeding up the curing process can reduce the overall strength and durability of the resin. Therefore, it is important to use the proper curing method for your project and to follow the manufacturer's instructions carefully.
