If you are working on a project requiring a waterproof finish, then you will want to know how to properly seal the resin. This can be done in several ways. Some common methods include spraying a clear sealant on your artwork, laminating your artwork with a paper covering, or applying a protective layer with a heat gun. The first two steps are crucial and can’t be ignored. You will want to use a clear sealant that is appropriate for your artwork.
Pouring epoxy resin
If you want to add a new dimension to your artwork, pouring epoxy resin is an excellent choice. Proper pouring techniques can prevent bubbles and allow a seamless coating. To pour epoxy resin, you should prepare your work area first. Once you’ve prepared your work area, you can pour epoxy resin into the desired shape and size. To get started, prepare a work station with parchment paper, 2x measuring cups, a craft stick, and all of the necessary supplies.
To ensure the safety of everyone, make sure that you have a clean working area. Pour the epoxy resin into a small cup, not a bucket or a large bucket. The mixture will self-level to one-eighth inch. After pouring, use a plastic spreader or disposable sponge brush to spread the mixture. The epoxy mixture needs about 45 minutes to cure before it can be painted or used for other projects. It can thicken depending on materials, room temperature, and other variables.
If you want to laminate a piece of paper, you will first need to prepare the piece. You can start by cutting the shape of the paper to be laminated, or use a craft knife or punch to punch out a series of quick shapes. It is important to seal the image properly to prevent unsightly splotches and uneven dark marks. Start by sealing one side of the paper, and then use a spray-on sealer to cover the entire page in an even, vertical movement.
You can also use art glue or decoupage glue for your paper. While these types of sealants leave a thin protective layer over the paper, it can easily smear ink. After the paper has dried, you can remove the glue bits with scissors. Then, repeat the process with a different piece of paper. You can also use several layers of glue for the different projects you have. When the final step is complete, you can now laminate paper with resin.
Applying a protective layer
One of the first steps to successful resin encapsulation is applying a protective layer of adhesive. This layer should be applied as per the directions on the sealant’s label. Ensure that the sealant dries completely before applying resin to prevent clouding. You can choose between two types of adhesives: brush-on or spray-on. Each type has its pros and cons, so choose the sealant type based on the type of artwork you are working with.
For a photograph or thin-paper piece, applying a spray sealer is ideal. Several layers are necessary for proper protection. Brush-on sealants are more suitable for thicker pieces of paper, and require less layers. Once dried, the sealant can be applied to the back of the paper and pressed in a heavy book overnight to flatten it. The process of applying a protective layer to seal resin is very simple, and there are some basic steps that you need to follow.
Using a heat gun
When you’re using a heat gun to seal resin, you’ll want to avoid overheating the resin, which can cause bubbles. Instead, gently de-gas the resin by holding the heat gun about 4 inches above the surface of the resin. This will allow trapped air bubbles to escape, smoothing out the surface of the resin. While using a heat gun to seal resin, keep these tips in mind.
The first thing to remember when using a heat gun is not to overheat the surface of the resin. Too much heat can damage the surface and even catch fire, so you should only use it in a controlled environment. To prevent hot spots, always use the gun on its lowest setting and move in a circular motion. This will help prevent hot spots and protect the surface. Once you are done, you can apply a protective coating over the entire area.
Testing wood before sealing resin
It is common knowledge that the best way to seal wood is to apply a thin layer of penetrating or unthinned epoxy. To determine if this is the best way to seal wood, you can test different kinds of resin on small wooden blocks and see what results they produce. Open-grained woods absorb the resin quickly, while close-grained woods take time to soak up the resin. Test pieces should be kept in a water bath for several days to see if the amount of resin absorbed is too high or too low.
The right sealant will depend on the kind of project you are pursuing. Make sure the piece is sturdy enough to handle a brush to apply the sealant. For example, if your wood project is an original charcoal drawing, a brush on sealant might tear or curl the paper. Alternatively, if you plan to mount a pastel drawing or a print, a spray-on sealant may be more suitable.
Choosing a UV-resistant sealant
When choosing a UV-resistant sealant, it’s essential to look for ingredients that minimize the effects of ultraviolet radiation. Some of these ingredients are designed to reflect or absorb UV radiation, while others are used as a substrate additive. UV screeners are used in sealant formulations to reduce the absorption of light by chromophores. They are useful for reducing the effects of harmful ultraviolet radiation on materials, and their effect is dependent on their concentration.
Butyl adhesive sealants offer excellent UV and moisture resistance. Butyl adhesive sealants are often used in applications where high-temperature and low-temperature resistance is needed. Butyl is not recommended for demanding construction applications, as it can’t be painted and may not resist shearing movement. It lasts for five to 10 years before needing a re-sealing job. Polysulfide sealants offer flexible solutions, and can be used in applications where UV resistance is necessary. They can be used in applications where submersion is required, and they can resist salt water and other chemical substances.
