How to make acrylic paint dry slower.

If you’ve ever found yourself frustrated because your acrylic paint dries faster than you can say “blend,” you’re not alone. Acrylics are known for their quick drying time, which can be a blessing and a curse. While it’s great for layering and quick projects, it can make blending and detailed work feel like a race against the clock. But don’t worry—I’ve got some tried-and-true tips to help you slow things down and give you more time to work your magic.

Why Do Acrylics Dry So Fast?

Before we dive into solutions, let’s talk about why acrylics dry so quickly. Unlike oils, which dry through oxidation, acrylics dry by evaporation. This means they lose water and binders as they dry, hardening into a flexible film. While this makes them durable and versatile, it also means they can dry in minutes, especially in warm or low-humidity environments.

What Can You Add to Slow Down Drying Time?

If you’re wondering, “What can I add to make my acrylic paints dry slower?” you’re in the right place. Here are some of the best options:


1. Acrylic Retarder

This is the MVP of slowing down acrylics. Acrylic retarder is a medium specifically designed to extend the drying time of your paint. It’s easy to use—just mix a small amount into your paint (a little goes a long way!). Be careful not to overdo it, though, as too much can make your paint tacky and prevent it from drying properly.



2. Slow-Drying Acrylic Paints

If you’re tired of adding mediums, consider switching to a slow-drying acrylic paint line. Golden’s Open Acrylics are a game-changer—they’re designed to stay workable for hours, even days, without needing any additives. You can also mix them with regular acrylics to extend their drying time.

  • Pro Tip: These paints are perfect for artists who love the feel of oils but want the convenience of acrylics.



3. Glazing Medium

Glazing mediums not only make your paint more transparent but also slow down the drying time. They’re great for creating smooth, blended layers and glazes. Golden’s Glazing Liquid is a popular choice.

  • Pro Tip: Use a soft brush and work in thin layers for the best results.

4. Flow Improver

Flow improver is another handy medium that not only improves the flow of your paint but also extends its drying time. It’s especially useful for detailed work or when you’re using a lot of water to thin your paint.

Techniques to Keep Your Paint Workable

Sometimes, it’s not just about what you add to your paint—it’s also about how you work with it. Here are some techniques to keep your acrylics from drying too fast:

1. Use a Stay-Wet Palette

A stay-wet palette is a lifesaver for acrylic painters. It keeps your paint moist for days, so you don’t have to worry about it drying out on your palette. You can buy one like this one or make your own with a shallow container, damp paper towels, and parchment paper.

  • Pro Tip: Mist your palette with water occasionally to keep the paint fresh.

2. Work in Smaller Sections

Instead of trying to tackle the entire canvas at once, focus on one area at a time. This way, you can blend and layer without feeling rushed.

  • Pro Tip: Use a spray bottle to lightly mist your canvas if the paint starts to dry too quickly.

3. Control Your Environment

Acrylics dry faster in warm, dry conditions. If possible, work in a cooler, more humid environment. You can also use a humidifier to add moisture to the air.

  • Pro Tip: Avoid direct sunlight or heat sources near your workspace.

What NOT to Do

While there are plenty of ways to slow down acrylics, there are also some methods you should avoid. For example:

  • Don’t use too much retarder—it can make your paint tacky and prevent it from drying properly.

  • Avoid household products like glue or cornstarch—they can alter the quality and longevity of your paint.

  • Don’t over-thin your paint with water—it can weaken the paint’s binding properties and make it less durable.

Finally…

Acrylics don’t have to dry at lightning speed. With the right mediums, techniques, and a little patience, you can enjoy the best of both worlds—the versatility of acrylics and the extended working time of oils. Whether you’re blending a sunset, adding fine details, or experimenting with glazes, these tips will help you take your time and create your best work.

So, grab your retarder, set up your stay-wet palette, and get ready to paint without the pressure. Happy creating!
