The first coat applied is gloss varnish that is left to dry for at least 6 hours and often overnight or even for a few days. The second coat is a 50/50 mix of satin and gloss varnish applied in the same manner as the gloss varnish.
The best way to seal and protect an acrylic painting is to use an acrylic varnish, which can be applied in a gloss, satin, or matte finish. This varnish protects against UV light, dust, and pollution while enhancing the color and texture of the painting. Ensure the painting is completely dry before application.
Avoid excessive water: Limit water use when diluting paint, as too much water weakens the bond. Layer properly: Apply thin layers, allowing each to dry before adding more. Use flexible paints: Acrylics with a flexible binder are less prone to cracking or peeling.
The best final coating for an acrylic painting is an archival varnish for acrylics. Golden makes some excellent ones in liquid or spray forms. They are available in matte, satin or gloss finish. You can use an MSA varnish if you want to later remove the varnish without altering the painting underneath.

If you choose a brush-on sealer, the application is really simple. Just squirt it directly onto your painting in sections and brush it on. I use a large, 2” flat brush and it works great. I am able to quickly cover the entire canvas with a nice, even coat of sealer.
I use the brand Liquitex. This will provide a layer between the actual paint and the top coat of varnish that we'll spray on later. This extra layer of protection will allow you to retouch the painting years down the road without damaging any part of the painting underneath. It is called an "isolation coat."
Avoid direct sunlight
Acrylic paintings are sensitive to prolonged exposure to direct sunlight, which can cause fading and damage the pigments. Display your artwork in a well-lit room but away from windows or use UV-filtered glass to protect it from harmful rays.
If you want something more durable, you can try an acrylic varnish or an acrylic polymer varnish. And if you're looking for a budget-friendly option, you can always use mod podge. If it's a painted glass surface, you might want to consider using a glass paint sealer.
If you want your acrylics to last even longer or keep your acrylic paint from drying out overnight, there are two main options. You either keep the colours in an airtight container or keep the paints in a stay-wet palette that 'feeds' the paint more water.

First a coat of acrylic primer is applied to the sides of the panel followed by two coats of acrylic paint in a colour that complements the colours of the painting. Next a coat of gloss medium is brushed on to seal the paint.
Cover the paint with a coat of Elmer's Glue-All glue. While still wet, paint on another coat of a different color of acrylic paint. The painted item will begin to crackle as it dries. When dry, cover with another coat of the Elmer's Glue-All as a sealer.
To achieve even more gloss, apply a high gloss varnish once the painting is finished and the paint is dry. There is a product by Liquitex that is both a gloss medium and varnish, so you could use it to mix with the paint as well as use it for a final coat of varnish.
Yes, you can use Mod Podge to seal acrylic paint on ceramic, but there are a few considerations to keep in mind: Type of Mod Podge: Ensure you're using a version of Mod Podge that is suitable for your project.
In general, acrylic resin varnishes are glossier, stronger and clearer than acrylic polymer varnishes. Therefore, if you want a high-gloss finish, you should go for an acrylic resin varnish such as Golden MSA Varnish. Before applying the final varnish, you'll need to apply an "isolation coat" over the entire painting.
Acrylic paint does not usually need a clear coat because it is already water-resistant and durable after drying. However, if you want to increase durability or add a glossy finish, you can apply a clear coat of varnish or sealant over the acrylic paint.
To make acrylic paint permanent on ceramic plates, you should bake the painted plate in an oven or use a sealant like a water-based polyurethane varnish, clear acrylic coat, or mod podge.
Protect From Atmospheric Conditions
Weather, light, and dust will harm youracrylic paintings . Constantly shifting temperature and humidity are paintings' worst enemies. If the temperature gets too hot or too cold, this can cause the paint to flake and become unstable.
For a shorter hiatus (like a few hours), you can use a wet palette instead. A wet palette continuously feeds water to your paints, thereby, letting them stay wet for longer. A wet palette can also be stored in your refrigerator to extend drying time.
