What is The Best Clear Coat for Acrylic Paint? Acrylic paints are a great way to add vibrant colors and texture to your paintings. They dry quickly, allowing you to layer paint on top without waiting too long in between layers. But one problem with acrylics is that they tend to yellow over time. This can be fixed by using a clear coat that will protect the painting from UV light and other environmental factors that lead to yellowing.
Let’s look at some of the best clear coats for acrylic paint:
Benefits Of Protecting Your Acrylic Paintings with A Clear Coat
Acrylics are great, but they do have one major drawback. When exposed to sunlight and other environmental factors, acrylic paint can turn yellow over time. This is due to oxidation, which causes the chemical bonds in the pigments of oil paints to break down over time, causing them to change color. Fortunately, you can fix this problem using a clear coat over the surface of your painting.
- A clear coat serves as a protective layer for acrylic paint and therefore extends the life span of your paintings.
- It prevents yellowing, so you don’t have to worry about repainting every time you want to change its color scheme.
- It also protects the paint underneath from fading with time.
- A clear coat is essential if you want to sell or exhibit your paintings in galleries, museums, and art shows where they are exposed to direct sunlight.
- Easy to clean and maintain
- A clear coat can also be easily removed if you want to repaint your painting.
Three Major Categories of Clear Coats
You will come across three major types of clear coats in the market. Each one has its own advantages and disadvantages. They are as follows:
1. Nitrocellulose-Based Clear Coats
These include products such as Galkyd Lite, Liquitex Clear Medium, or Liquitex Matte Varnish.
Nitrocellulose is a flexible resin that can be used in paints and varnishes. It has good adhesion properties that allow it to adhere well to the paint, so it is important to ensure the surface of your painting has been properly prepared before applying a nitrocellulose-based clear coat.
Nitrocellulose varnishes are also known for their softening effect on oil paints that contain large amounts of linseed or poppy oils. This property can alter the consistency and flow of your paint.
Nitrocellulose-based clear coats are also not very durable and need to be refreshed every so often, depending on how much you use them.
Nitrocellulose-based clear coats are not ideal for large paintings, especially those that take longer than six months on average to complete. The reason is that they tend to yellow over time or even crack under certain conditions of use.
2. Acrylic-Based Clear Coats
These include products such as Liquitex Acrylic Gesso and Liquitex Heavy Body Professional Matte Medium.
Acrylic-based clear coats are water soluble, meaning they can be washed away or removed with soap and water. They also dry very quickly, so you do not have to wait long before applying a new layer of paint on top of it.
Acrylic-based clear coats are more transparent than nitrocellulose varnishes, which means that they do not soften the overall look and feel of your painting as much.
They also have excellent adhesion properties, making them ideal for large paintings or those applied over other protective coatings.
However, acrylic-based clear coats are not very durable and can break down easily when exposed to different environmental factors, such as humidity or sunlight exposure over long periods of time.
They also tend to yellow over time with extended exposure to light sources that emit ultraviolet rays like the sun.
3. Acrylic-Alkyd-Based Clear Coats
These include products such as Liquitex Professional Clear Medium or GAC 100.
Acrylic alkyd varnishes are the best choice if you want a durable coating capable of protecting your acrylic paintings for long periods. They also provide good flow and consistency to oil paint, although they do not have the same softening effect as nitrocellulose varnishes.
Acrylic-alkyd-based clear coats are also very durable and can be used to protect your paintings from environmental factors such as humidity, direct sunlight, or prolonged exposure to heat sources that emit ultraviolet rays, like light bulbs or sun lamps.
They provide a high level of clarity that makes your paintings look natural and not made up.
However, the only downside is their high price which can be prohibitive to some artists on a limited budget.
Factors To Consider When Choosing the Best Clear Coat for Acrylic Paint
You will need to consider several factors when choosing the best clear coat for your acrylic paintings. They include:
1. Pricing and Availability
You may also want to choose a product available at local art stores near you. Hence, it is easier to resupply if necessary without paying expensive shipping fees or waiting for online orders to arrive.
2. Environmental factors
Make sure the clear coat you choose is UV-resistant if exposed outdoors or under direct sunlight over long periods of time. Some acrylic-based clears can turn yellow with exposure to ultraviolet light, which will affect how your paintings look after some period of time has elapsed.
3. Durability
You will need the best clear coat that can provide a tough, hardwearing finish that protects your acrylic paintings for many years without cracking or peeling off due to exposure to different environmental factors like moisture and direct sunlight exposure.
4. Ease of Application
Look for a product that is easy to apply by brush or roller. Some clear coats can be tricky because they may require you to mix the contents before applying, which requires additional time and effort.
5. Ease of Removal
If you make mistakes while applying your clear coat, it can be removed using alcohol or mineral spirits, so choose a safe product for this purpose in case the need arises.
6. Environmental Impact
Choose a product that is manufactured according to environmental standards. This means it does not contain volatile organic compounds (VOCs) or formaldehyde, which are harmful to the environment and your health too.
