Do you need to seal resin?

Resin art is one of the easiest ways to get started with DIY projects. It’s versatile, easy to use, and perfect for beginners.

While sculpting with resin can be a fun hobby, you likely want to take your work to the next level by sealing it once it’s cured.

Then again, maybe not—since there are so many factors that play into whether or not you’ll need this step in your process.

In this article, we’ll go over some common questions about sealing resin so that you can make an informed decision about how best to protect your work!

Does epoxy resin need to be sealed?

If you’re using epoxy resin, the answer is no. Resin will not stick to itself or to cured resin. So if you’re just sealing a small section of your table, there’s no need to use a sealer.

You can simply apply another layer of epoxy over the existing one and it will create a stronger bond with the wood than before.

However, if you plan on sealing multiple surfaces or have any doubts about whether your sealer will work in all areas of your project, definitely apply it! The last thing you want after spending so much time and money making something beautiful are for it not to stay together because there was an issue with one part that wasn’t sealed properly.

How do you seal a resin?

There are several different types of sealant, and you need to know which one your product takes. If you don’t see your type listed, call or contact the manufacturer directly. Here are some common types:

  • Polyurethane sealants – These provide a glossy finish that is often used for countertops, tables and kitchen cabinets. They can also be used on bathtubs and showers. The polyurethane resin is cured by hardening in place, rather than being catalyzed with solvent or water as other resins require; this makes polyurethanes harder than other types of resin-based sealants but not as flexible (which means it won’t flex with movement), so they should only be applied after the surface has been prepared for priming using alcohol or acetone mixed with denatured alcohol if necessary

Does resin stick to cured resin?

resin sticks to cured resin. It’s not a good idea, though.

If you’re going to be displaying your work out in the world, it’s best to seal your resin pieces with a hard coating like glass or plastic.

This will help protect them from dust and moisture, which can cause the resin surface to cloud over time.

How do beginners use resin?

There are a ton of different resin materials out there. Some are better than others, and some are easier to use than others.

For beginners, you’ll want to choose a resin that is easy to mix, apply, clean up and cure. A good way to do this is by choosing a resin with an Ease of Use score higher than 50 on our site (or read reviews).

Do you need to seal resin art?

The short answer is no, you don’t have to seal resin art. Resin is a durable material and can be considered “sealed” by its own nature.

However, if you want your resin piece to look its best and last longer than time will allow it to naturally, there are several ways you can apply a protective layer over your work.

You’ve probably seen some of this before: the shiny surface on many plastics that makes them look like they’re coated with oil or grease but isn’t actually sticky or greasy at all?

That’s called a “film finish.” And films (or finishes) aren’t just for plastics; they can also be applied to resins as well!

If you’re interested in giving your resin piece an extra layer of protection without changing the color or texture of your original artwork, there are two main types of films that work well for this purpose: UV-cured and solvent-based clear coatings (also known as varnishes).

Can you seal over resin?

Yes, you can certainly seal resin with more resin.

I’ve done it many times, and I’ve never had any problems. This can be done either with a clear coat or an opaque one—but only if the finish is glossy.

If you want to coat your piece with a matte-finish varnish or wax, then it won’t have any effect on your resin topcoat (which will still remain glossy).

How do you seal painted resin?

Resin is a liquid that hardens with exposure to air. It’s used in many applications, from fiberglass boat building to wood flooring to casting jewelry. There are several types of resin:

  • Epoxy resin is used for adhesives and glues, as well as for making molds and casts. It’s also the main ingredient of gel coat (the glossy finish on a fiberglass boat).
  • Polyester resin: This type of hardener works well with polyester paints but not acrylic paints because they contain water.
  • Polyurethane resin: This is typically used in products where you want something flexible yet durable like pool noodles or diving boards.
  • Polycarbonate resin: This type of hardener has better clarity than other resins so it’s often used in making microscope slides or lenses for eyeglasses.

How do I keep my resin from leaking?

If you’ve never used resin before, the thought of it leaking out of your house and destroying everything in its path may be cause for panic. However, there are several ways to prevent leaks from happening.

  • Use a sealant: Sealants are formulated specifically to prevent resin from seeping through cracks in the walls and floors of your home but also keep water from getting into them as well. They come in both liquid and solid forms so you can choose whichever one is best for your needs.
  • Use a wax polish: Wax polishes contain particles that act as a barrier between wood surfaces and any liquids (including resin) that come into contact with them, making it harder for those contaminants to get through the surface layers of wood without being absorbed first by these sealants instead. This will help keep moisture away from where they shouldn’t belong while still allowing airflow through properly treated areas like raised grain patterns or knots.”


This is a great question and one that we hear often. With the right tips, you can seal your resin without any issues at all! We recommend using our Clear Sealer or White Sealer as these are specifically made for sealing resin products.

Also, always use a clean rag when applying any sealers so they don’t get contaminated with dirt or dust particles which could potentially stain later on down the line after many uses
