Types of Acrylic Paint Sealer

There are many different types of acrylic paint sealers, each with its advantages and disadvantages.

Here is a brief overview of some of the most popular types of sealants:

1. Polyurethane

Polyurethane is a type of synthetic resin that is often used as a sealant for acrylic paint.

It is available in both water-based and oil-based paints, and it can be applied using a variety of methods, including brushes, rollers, and spray guns.

Polyurethane has a number of advantages as a sealant, including its ability to resist weathering, fading, and chipping.

Additionally, it provides a durable barrier that helps to protect acrylic paint from scratches and other damage.

Polyurethane can also be used to give acrylic paint a glossy finish. However, it should be noted that polyurethane is not always suitable for use with all types of paint.

So it is important to check the compatibility of the two products before application. Another drawback is that it can yellow over time and is difficult to remove once it has been applied.

But all in all, polyurethane is the first choice wood sealant for acrylic painters.

How to seal acrylic paint on wood with polyurethane

When sealing acrylic paint on wood for outdoor use, choosing a polyurethane specifically designed for that purpose is important. Either oil or water-based polyurethane.

There are many different types of outdoor polyurethanes on the market, and they vary in terms of their durability, UV resistance, and other factors.

It is important to select a product suitable for the specific type of wood you are working with, as well as the conditions in which it will be used.

For example, if you are sealing a piece of furniture that will be exposed to direct sunlight, you will need to choose a polyurethane with UV protection.

Applying polyurethane to outdoor furniture is similar to applying it to indoor furniture, but there are a few important differences to keep in mind.

  • First, you will need to clean the furniture’s surface before application. This can be done with a mild detergent and water.
  • Next, the polyurethane must be diluted with mineral spirits before application. This is because the polyurethane will not adhere properly to the surface if it is too thick.
  • Once the polyurethane has been diluted, it can be applied using a brush, roller, or spray gun.
  • It is important to apply evenly and avoid applying too much pressure, as this can cause bubbles to form in the finish.
  • Once the polyurethane has been applied, it will need to be left to dry for 24 hours before use.

2. Furniture Wax

Furniture wax or wax-based sealants are another popular option for sealing acrylic paint on wood. They are available in clear and tinted formulas and can be applied using a soft cloth or sponge brush.

Furniture wax provides a durable barrier that helps to protect the underlying paint from scratches and other damage.

Additionally, it can be used to give the paint a glossy or matte finish, depending on your preference.

However, furniture wax is not suitable for use with all types of paint, so it is important to check the compatibility of the two products before application.

Furniture wax is easy to apply and can be found at most hardware stores. However, it is important to test the wax on a small area of the wooden surface before applying it to the entire piece of furniture.

It is an unconventional but effective way to protect your painted furniture.

How to apply furniture wax

  • To apply furniture wax, start by dusting the surface of the furniture with a soft cloth.
  • Next, apply a small amount of wax to a lint-free cloth and rub it into the furniture’s surface in a circular motion. Continue until the entire surface is covered.
  • Once the wax has been applied, buff it to a shine with a clean cloth. Furniture wax can be applied as often as needed to maintain the desired finish.

3. Polyacrylic Sealant

Polyacrylic sealant is a clear, water-based product that can be used to seal acrylic paint on wood.

It is available in matte and glossy finishes and can be applied using a brush or roller.

Polyacrylic sealant dries quickly and provides a durable, protective barrier against scratches and other damage.

Additionally, it is resistant to yellowing and fading, making it an ideal choice for outdoor surfaces.

How to apply polyacrylic sealant

  • To apply polyacrylic sealant, start by stirring the product thoroughly.
  • Next, apply a thin, even layer to the surface of the furniture using a brush or roller.
  • Once the sealant has been applied, it will need to be left to dry for 24 hours before use.

4. Clear Sealant for Wood

Clear sealant for wood is another option that can be used to seal acrylic paint on wood.

This type of sealant will protect the paint from scratches and other damage that can occur over time.

It is also important to note that clear sealants can be applied to both finished and unfinished wood surfaces.

When choosing a clear sealant, selecting one that is non-yellowing and has a finish that you are happy with (matte or glossy) is important.

Additionally, you will want to ensure that the brushstrokes will not show through after applying the sealant.

Finally, selecting a sealant that is simple to clean up is always a good idea. Water-based sealants are typically the easiest to work with.

How to apply clear sealant for wood

When it comes to how to seal acrylic paint on wood, there are a few different methods that you can use.

One option is to brush a thin coat of the sealant onto the surface of the wood. This method is typically best for small projects or areas where you need to be very precise with your application.

Another option is to spray the sealant onto the wood surface. This method is often best for larger projects or areas where you need to cover a larger area quickly.

Regardless of which method you choose, it is always a good idea to test the sealant on a small area of the wood first to make sure that you are happy with the results.

  • Once you have applied the clear sealant to the wood surface, you will need to allow it to dry completely before proceeding.
  • This can take anywhere from a few hours to a few days, depending on your product. Once the sealant is dry, you can then proceed with applying your acrylic paint.
  • It is important to note that clear sealants are not typically necessary for outdoor projects.
  • However, if you are working on an outdoor project that will be exposed to the elements, it is always a good idea to use a clear sealant to protect your work.

5. Varnish

Varnish is a clear acrylic paint sealant that can be used to protect your paintings from dirt, dust, and UV rays.

Varnish can also add a glossy finish to your painted wood surface, making it look more professional.

While varnish is not necessary for all acrylic paintings, it can be useful for paintings that will be displayed in high-traffic areas or exposed to direct sunlight.

Varnish is available in both water-based and oil-based formulas, so be sure to choose the right type of varnish for your painted wood crafts.

Applying varnish is easy – simply brush it on evenly and allow it to dry. Varnish can also be removed easily with fungicide if you ever need to change the look of your painting.

6. Glaze

Glaze is often used as an acrylic paint sealant. It is a clear or opaque coating that is applied over an existing layer of paint.

Glaze can be used to protect the paint from damage, enhance the paint’s color or sheen, or change the paint’s color.

The finish is also used to create special effects, such as faux finishes. Glaze is available in a variety of different finishes, such as matte, satin, or high-gloss.

Glaze can also be tinted with colorants to create a variety of different effects. Glaze is typically applied with a brush or roller and then allowed to dry.

7. Epoxy Resin

Epoxy resin is a synthetic polymer with many uses, including an acrylic paint sealant. Epoxy resin is made up of two parts, a resin, and a hardener.

When these two parts are mixed together, they create a tough, durable material that can be used to protect surfaces from scratches, UV light, and water damage.

Epoxy resin is often used as a clear coating on wood or metal surfaces, but it can also be tinted with pigments to create a variety of colors.

While epoxy resin is more expensive than other paint sealants, its durability and versatility make it worth the investment.

How to seal acrylic paint on wood with epoxy resin

  • To seal your painting with epoxy resin, you must mix the resin and hardener.
  • Once they are mixed together, you can then brush or pour the mixture over your painting.
  • The amount of time it takes for the resin to cure will vary depending on the product you use, so be sure to follow the manufacturer’s instructions.
  • Once the resin is cured, it will create a tough, durable surface that will protect your painting from damage.

8. Gel Medium

Gel medium is a thickening agent that is used to thicken up acrylic paint to change its consistency. Gel medium can also be used as an acrylic paint sealant.

When mixed with acrylic paint, gel medium will create a thick, glossy finish that is perfect for protecting wooden surfaces from scratches and UV light.

Gel medium is available in a variety of different finishes, such as matte, satin, or high-gloss.

Gel medium can also be tinted with colorants to create a variety of different effects. Applying gel medium is easy – simply mix it with your paint and then brush it on evenly.

What to Look Out for When Choosing a Sealant

When choosing an acrylic paint sealant, there are a few things that you should keep in mind.

Non-yellowing

One of the most important things to look for in an acrylic paint sealant is that it doesn’t yellow over time.

Acrylics are known for their lightfastness, but even the best quality paints can start to appear amber yellow in color after a few years if they’re not properly sealed.

A non-yellowing sealant will help to keep your paintings looking bright and vibrant for years to come.

In addition, a good sealant will also protect your paintings from UV damage, fading, and other environmental factors.

When choosing a sealant, read the label carefully to ensure that it will provide the level of protection you need.

Finish (matte or glossy – select your preference)

Another thing to consider when choosing an acrylic paint sealant is the finish. Sealants are available in a variety of different finishes, including matte, satin, and high-gloss.

The type of finish that you choose will depend on your personal preference. For example, if you want a glossy finish, select a sealant specifically designed for use with acrylics, such as glossy acrylic medium sealant.

If you prefer a matte finish, there are also sealants that can provide this type of finish.

Brushstrokes will not show

When sealing a painting, you want to ensure that the sealant goes on evenly and doesn’t leave any brush strokes behind.

A good sealant will self-level, meaning that it will smooth out as it dries. This will help create a smooth surface that won’t show any brushstrokes.

Self-leveling

As we mentioned before, a good sealant will self-level as it dries. This means that it will smooth out any imperfections and create a uniform surface.

This is important because you want your sealant to dry evenly and smoothly without brushstrokes or streaks.

Simple to clean up

Another thing to look for in an acrylic paint sealant is that it is simple to clean up. This means it won’t leave any residue or streaks when you’re finished applying it.

A good sealant will also be water-based, so it will clean up easily with soap and water.

Water-based

When sealing a painting, you want to ensure that the sealant is water-based. This means it won’t damage the paint or the surface you’re sealing.

Water-based sealants are also easy to clean up, so you won’t have to worry about leaving any streaks or residue behind.

How to Seal Acrylic Paint on Wood

Now that you know what to look for in an acrylic paint sealant let’s take a look at how to apply sealant.

To seal acrylic paint on wood, you will need:

  • A brush/roller/sprayer

  • A clean, soft lint free cloth

How to seal acrylic paint on wood for outdoors – step by step

Step one: Prepare your painted surface

Before you start, you need to ensure that the surface you’re going to seal is clean and dry.

You can do this by wiping it down with a clean, damp cloth. If there are any areas that are particularly dirty or greasy, you can use a mild soap and water to clean them.

Once the surface is clean, you need to ensure that it is completely dry before applying the sealant.

Step two: Apply the sealant

Now it’s time to apply the sealant. Again, you can do this with a brush, roller, or sprayer.

If you’re using a brush or roller, apply the sealant evenly and smoothly.

If you’re using a sprayer, hold it about 12 inches away from the surface and apply the sealant in even, overlapping strokes.

Step three: Let it dry.

Once you’ve applied the sealant, you need to let it dry completely. This usually takes about 24 hours. Once it’s dry, you can enjoy your newly sealed surface!

  • If you’re using a sprayer, hold it about 12 inches from the surface.

How to Seal Acrylic Paint on Glass

Sealing acrylic paint on glass differs from sealing it on wood.

This is because glass is a non-porous surface, so you don’t need to worry about the paint being absorbed by the glass.

To seal acrylic paint on glass, you will need:

  • A brush/roller/sprayer
  • An acrylic paint sealant
  • A clean, dry cloth

Step one: Prepare your surface

As with wood, you need to ensure that the surface you’re going to seal is clean and dry. You can do this by wiping it down with a clean, tack cloth.

Step three: Let it dry

Once you’ve applied the sealant, you need to let it dry completely. This usually takes about 24 hours. Once it’s dry, you can apply a second coat if you want to.

How to Seal Acrylic Paint on Plastic

Acrylic paint is a versatile medium that can be used on a variety of surfaces, including plastic.

However, unlike other surfaces, plastic is not porous, so the paint has a tendency to crack and peel.

To avoid this problem, you need to seal acrylic paint on plastic with a clear finish. There are several types of sealers that can be used, but the best one for plastic is polyurethane.

  • To apply polyurethane, first lightly sand the surface of the plastic with fine-grit sandpaper to create a smooth surface.
  • Then, apply a thin layer of polyurethane with a brush or roller and allow it to dry for 24 hours.
  • Once it is dry, apply a second coat and let it dry for another 24 hours. After the final coat has dried, you can then apply a layer of furniture wax to protect the finish.

Sealing acrylic paint on plastic for outdoor use

To seal acrylic paint on outdoor plastic, you will need to use a clear sealant. There are several types of sealers that can be used, but the best one for plastic is a polyacrylic sealant.

This type of sealant will create a waterproof barrier that will protect the paint from the elements.

  • To apply polyacrylic sealant, first sand the surface of the plastic with fine-grit sandpaper to create a smooth surface.
  • Then, apply a thin sealant layer with a brush or roller and allow it to dry for 24 hours.
  • Once it is dry, apply a second coat and let it dry for another 24 hours. After the final coat has dried, you can then apply a layer of furniture wax to protect the finish.

Sealers Versus Primers

One thing to keep in mind when selecting a sealant is that there are two different types: sealers and primers.

Sealers are designed to protect the surface from damage, while primers are designed to help the paint adhere to the surface.

When sealing a painting, you want to ensure that you’re using a sealer and not a primer. Primer is best used when painting wood.
