Acrylic paint is one of the best tools to start your journey as an aspiring artist, as it’s quite easy to spread and dries fast to bring your canvas to life. It delivers vibrant colors and is safer around pets and children. Moreover, more experienced artists love how it’s effortless to mix, so they can get the precise shade that they’re looking for.

When you buy a high-quality paint by numbers kit, you’ll receive a set of all the necessary colors that allow you to complete your artistic creation. When you follow the instructions, you’ll have a replica of the masterpiece appearing on the box with no issues.

However, sometimes your paint doesn’t spread as smoothly as you wish it could, and you end up with a lumpy texture. This doesn’t mean that you received a faulty product or your paint is bad. Nevertheless, if you’re new to painting, the look of lumpy acrylic paint can affect your enthusiasm to finish your project.

Although acrylic paint is an excellent paint, it can create a lumpy texture on your canvas for several reasons.

  • You haven’t picked up the right place to work on your artistic project. Acrylic paint is water-based, and strong air will make it dry faster than it should. The fast-drying feature is one of the pros of using acrylic paint, but when the paint dries too fast on the palette or on your canvas, you’ll have lumps of paint that don’t spread as smoothly as they should.
  • You’re adding too many layers too fast. Of course, acrylic paint is great for the layering effect, but if you don’t wait until the first layer is dry, you’ll end up with lumpy paint that ruins the look of your canvas.
  • You left the paint pot open. High-quality paint by number kits arrive with all the shades of paint that you’ll need to complete your project. But you might choose to save your project for summer vacation or a trip away from home. If you haven’t made sure that the pots are perfectly sealed and closed, the water-based paint will dry.
  • You’re using too much paint. Acrylic paint can give you rich shades, but this doesn’t mean that you should use a lot of paint on the brush. You should add an adequate amount, then add more where necessary to achieve the desired effect. Start with a thin coat and stretch your paint to examine the coverage before you decide to add more to avoid the lumpy effect.

How to Fix It: 3 Simple Ways

Don’t worry if you end up with lumpy acrylic paint. You can still have a flawless canvas using simple techniques and tools. Let us help you learn how to fix lumpy acrylic paint.

How to Fix Lumpy Acrylic Paint in Containers

Before working on your art project, you can make sure that the paint will apply smoothly and there will be no lumps that might affect the look of your canvas. Acrylic paint can get lumpy and clumpy if it’s been sitting for too long. This doesn’t mean that the paint is of low-quality. It simply means that the texture of the paint has changed because the water has evaporated.

This also happens if you have been leaving the pots open. The water evaporates and affects the consistency of the paint, so it doesn’t apply with a smooth finish, and you end up with ugly lumps on your canvas.

However, you can use a simple tool to make sure that your paint will be lumps-free. This will allow you to apply various coats to layer your paint and achieve the desired effect.
