To make acrylic paint truly permanent, allow it to completely dry and cure for at least 72 hours. Afterward, seal the surface with a clear acrylic sealer or varnish. If you are painting on fabric, mix the paint with a fabric medium and heat-set it with an iron.
Keep Acrylic Paints Sealed Tightly
Always make sure to screw the caps or lids on tightly after each use. Even a small gap can cause the paint to dry out inside the container, hardening and becoming unusable.
Adding baking soda to acrylic paint acts as a thickening and texturizing agent, turning the paint into a thick, gritty paste with a matte finish. While great for crafts and faux-ceramic decor, it disrupts the paint’s chemical binders, which can cause cracking and peeling over time.
To seal acrylic paint and protect it from dust, UV fading, and moisture, you can use an acrylic polymer varnish, a polyurethane clear coat, or Mod Podge. Choose your sealer based on the item's surface and whether it will live indoors or outdoors.
It does make the paint thicker and it lightens the color somewhat. I'll also mix it with Liquidex Basics and then heavy body acrylics.
Yes, you can mix Elmer's glue with acrylic paint. Because both are water-based and contain PVA (polyvinyl acetate), they blend together easily. This combination is frequently used for craft projects, thickened impasto textures, and as an affordable pouring medium for fluid art.
No, you should not use hairspray to seal acrylic paint.
Disadvantages: because acrylic paints dry quickly they cannot be easily blended to create the 'wet in wet' technique that is popular with oil paints. For this reason, a finished acrylic painting can look harsh compared to a finished oil painting.
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.
I used to do this when i started out before I brought better quality paints (my first minis were done with $10 pack of acrylic paint in tubes from the stationary shop!). Dish soap breaks down the surface tension of water which helps it flow into cracks and crevices.
Yes, you can absolutely mix Dawn, vinegar, and baking soda. This combination is a highly effective, non-toxic DIY cleaning trio. The grease-cutting power of Dawn, the acidity of vinegar, and the mild abrasiveness of baking soda make it perfect for tackling tough grime, soap scum, and baked-on messes.
Acrylic Retarder (299)
One of the key ways to extend your working time with acrylic paints is by using an acrylic retarder. This medium slows down the drying process of your paint, allowing you to work with it for longer periods. Simply mix a small amount of the retarder with your acrylics.
Yes, acrylic paint is highly permanent once it dries. Because its binder is made of acrylic polymer (a type of plastic), it transforms from a water-soluble liquid into a tough, water-resistant, and flexible film.

9 Tips for Making Acrylic Nails Last Longer
Yes, it is recommended to wet your brush when using acrylic paint, but it should be damp, not soaking wet. A damp brush helps paint flow smoothly, prevents it from drying too fast, and makes it easier to clean, which protects the brush bristles and prevents paint from entering the ferrule.
Many users have found that a mixture of Dawn dish soap and water excels at effortlessly breaking down acrylic paint. The key is spraying the solution onto the painted surface for quick removal that works efficiently between children's nap times, when every minute is critical.
They only become toxic when used for airbrushing, or when sanded, or if large amounts are accidentally ingested. For the most part, when you use them for typical acrylic painting purposes (applying them with a brush to the canvas), then they won't be harmful to you.
Some artists also report success with Krylon Kamar spray varnish, which provides a non-yellowing protective coat over oils and acrylics. You can even continue reworking the artwork after you apply it.
Common Acrylic Painting Mistakes and How to Avoid Them
To make your acrylic paint last longer, focus on keeping it hydrated during use and properly sealed in storage. Because acrylics dry via water evaporation, your main goal is to slow down that process.
Yes, mild dish soaps like Dawn are safe for cleaning acrylic tubs. Mix a few drops in warm water and use a soft cloth or sponge to clean your tub. This method gently removes soap scum, body oils, and minor stains without damaging the acrylic surface. It's one of the simplest ways to clean an acrylic bathtub regularly.
Yes, vinegar can remove acrylic paint. Because it is mildly acidic, vinegar softens the polymer bonds in acrylic paint, making it easier to wipe or scrape away. It works best on wet paint or for loosening dried paint on hard surfaces and synthetic brushes, though it may be less effective on heavily cured fabric stains.
"Don't use WD-40 on plastic components under stress, like window tracks or drawer slides made from polycarbonate or acrylic," says Orlando Penner, building manufacturing expert and owner of South Country Sheds. "It tends to soften certain plastics, making them brittle.
