Questions You Should Know about water-based epoxy resins
Dec. 16, 2024
The most frequently questions about epoxy resin: Q&A
1. What is epoxy resin?
Its a polymer consisting of two components, a base and a catalyst, which solidify with air when they are mixed together.
To obtain the solid effect it is important to consider the right proportions; the instructions are usually on the box.
2. Why use resin floors?
The resin floors are suitable for every kind of environment. It can be used also for outdoor spaces such as gardens, terraces, and sports fields. This kind of coating is weather and wear-resistant and for this reason, is chosen for the environment with frequent passage.
3. In how much time does the resin solidify?
From 24 hours up to 7 days after the application.
4. Can we cut or drill holes in the solid resin?
The solid resin can be processed with cutting tools as if it were hard plastic.
5. Can the resin be coloured?
The transparent resin can be coloured with pigments, natural or artificial dust, with semi-liquid or liquid substances that create the desired tonality.
Liquid substances are inks and colors, semi-liquid substances are concentrated paste dyes, while powders are those that interfere less with the catalysis process.
6. How do I clean a resin floor?
Resin is easy to clean because it isnt an absorbent material without joints. Warm water and cloth are sufficient. In case of stubborn dirt, you can add mild soap. We advise against ammonia that can ruin the surface if left to act. In case of stubborn dirt, you can add mild soap. We advise against ammonia that can ruin the surface if left to act.
7. Is the resin waterproof?
The resin is water-resistant.
For this reason, it is used by sport or public facilities, in particular those used by the elderly.
8. Can the resin floor be adorned with objects?
The resin floor can be adorned with the introduction of objects as long as they are not too thick. Its a good idea to accurately clean the objects before introducing them.
9. Can we restructure a broken resin floor?
A resin floor can be repaired in two ways: restructuring the resin layer or treating the surface; thanks to specific machinery it is possible to remove the damaged layer and reapply the resin giving new life to the floor.
10. Can we put the underfloor heating with a resin floor?
Because the layer of resin is thin, this material is suitable for heat transfer without suffering damage.
For this need, in particular, Gobbetto suggests Dega Energy, an innovative, non-toxic resin, with strong conductive properties.
Applied to a heating system with radiant panels, an energy saving of approximately 20% is achieved.
The metallic properties of this material retain the heat because of the conductive floor. It releases the heat more slowly and efficiently.
Our top 10 epoxy resin FAQs
We receive a lot of questions about epoxy resin on a daily basis, so we decided to list our answers here for others to find.
Epoxy Resin FAQs
Here are some of the most frequently asked questions about epoxy:
#1:
"How long does epoxy last?"
If applied properly, cured epoxy will last for about 7 years before needing a touch-up.
At that point, many users will simply sand the surface and add a new coat of epoxy to make it look good as new.
Unmixed epoxy resin, on the other hand, has a shelf life of about:
- Unopened - 1 year
- Opened - 2 months
For more information, visit our epoxy resin storage guide.
#2:
How do you get bubbles out of epoxy resin?
The easiest way is to use a heat gun or propane torch after pouring your epoxy to remove any air bubbles.
If your epoxy has already cured significantly, you'll need to let it finish curing and then sand it down dramatically until the bubbles are removed.
Click here to learn more about both of these methods.
#3:
How long do you wait between applying layers of epoxy resin?
This varies slightly depending on environmental conditions and epoxy type.
For table top epoxy, we recommend waiting at least 4 hours before applying another coat. If more than 10 hours have passed, you can lightly sand the epoxy first, then apply your new layer.
For deep pour epoxy, we recommend waiting 12 hours before applying an additional coat. If 24 hours have passed, you should sand first, then apply the new coat.

How long does it take for epoxy to dry?
To fully cure (dry), epoxy needs about 72 hours after pouring and removing air bubbles.
Our resin curing times article addresses this in more detail.
#5:
How long should you wait before sanding epoxy?
For heavy sanding intended to give your epoxy a polish or matte finish, you should let it fully cure. This is generally 72 hours after pouring and removing air bubbles.
We've written two guides to sanding based on project shape/size.
- How to sand epoxy resin - Our sanding guide for medium-to-large projects such as tables, countertops, etc.
- Sanding resin art: A step-by-step guide - Our sanding guide for small projects such as resin art, coasters, jewelry, etc.
#6:
How do you polish resin after sanding?
This is actually a fairly involved procedure, so we've written two guides to polishing based on project shape/size.
- Our step-by-step guide to polishing epoxy resin - Our polishing guide for small projects like resin art, jewelry, coasters, etc.
- Our step-by-step guide to polishing larger epoxy projects - Our polishing guide for larger projects like epoxy countertops, table tops, etc.
#7:
How do you clean epoxy countertops?
Soap and warm water will do the job well. Don't use vinegar, as the acetic acid it contains can cause damage over time.
Avoid strong chemical like acetone and any "thinners".

What is resin?
Resin is a loosely used term that usually refers to one of the following:
- Epoxy resin (synthetic)
- Polyester resin (synthetic)
- Silicone resin (synthetic)
- Plant resin (natural)
Epoxy resin
Epoxy resin is a plastic polymer typically stored in an incomplete form as two liquid components: a resin component and a hardener component.
When these components are mixed together, a chemical reaction causes them to generate heat, bonding to any surfaces they can, while hardening significantly.
Epoxy resin is one of the hardest and strongest resins, lacking flexibility.
Polyester resin
Polyester resins are similar to epoxy in that they are plastic polymers that bond to surfaces and harden to become a tough material.
They tend to be cheaper to purchase but are less durable and are more toxic and volatile in their uncured state.
These are often used at a mass production level to create things like fiberglass for boat hulls, paddles, pipes, and much more. DIY use is generally uncommon due to the safety concerns and trickiness of using polyester properly.
Learn more about this in our Epoxy/Polyester Comparison explainer.
Silicone resin
Silicone resin is a synthetic polymer that is used to make a tremendous variety of different items.
This includes things like cooking tools, clothing, electronic equipment, and many useful materials for repair and maintenance.
Most people will be familiar with the cooking side of silicone, such as baking molds and silicone spatulas.
Silicone molds are used for epoxy resin casting because epoxy can't bond with them.
Plant resin
Plant resins are actually a wide category of natural resins created by different plants.
Many trees will release resin when they're damaged as a defensive mechanism to protect exposed surfaces while they mend.
Natural resins can be used for a wide variety of purposes, including varnishes, cosmetics, adhesives, and medicine.
Usually these resins break down naturally. Once in a while, however, that process is thwarted, and the resin instead fossilizes, becoming amber.
#9:
What materials does epoxy resin not stick to?
Silicone is the number one material that won't bond with epoxy resin. Nearly every other material will bond to some extent, though in certain cases the bonds may be fairly weak.
For a list of ideal materials to apply epoxy to, take a look at our compatibility page.
#10:
Why is my epoxy sticky?
This happens when the epoxy hasn't been mixed properly with the correct ratio (e.g., 1:1 for UltraClear Table Top Epoxy).
If part of one component is unblended, it will remain in a viscous liquid state indefinitely instead of curing as it should.
It's important to measure accurately when filling a mixing container. Be sure to closely follow the mixing instructions to avoid missing parts of the resin while blending.
Our support site covers this issue in more detail and provides solutions.
Note: Sometimes this is actually due to using a low-quality epoxy resin. When purchasing epoxy resin, always choose a brand from a reputable seller that has a credible reputation.
