Is acrylic paint waterproof

Acrylic paint is used by almost all artists in every industry imaginable. This is because they perform super well on almost every surface.

At the same time, they are cheap and easily available. Applying acrylic paint is also very easy, and they are often multipurpose paint mediums. But every multipurpose paint medium has to be resistant to environmental factors.

What are the advantages of waterproof paint?

Why are we looking for waterproof paint in the first place? Waterproof paint has several advantages, some quite self-explanatory, while others not so much.

Waterproof paint can be used out of doors.

Only a waterproof surface of the paint will last in outdoor conditions. Even if your area receives very little rain, there is still enough humidity and moisture out of doors to affect the condition of your painted surface.

A waterproof acrylic paint, which is quite easy to do, can make your homemade projects last for an everlasting time in your garden or backyard.

Waterproof paint makes surfaces easier to clean.

You will probably not be able to clean a surface that is painted with acrylic paint and is not waterproof. This will limit how you use it and whether your customers actually buy your product. A waterproof paint surface makes cleaning any object easier with soap and water.

Therefore, for objects of daily use, a waterproof painted surface is necessary. Although, it should be remembered that a waterproof acrylic paint surface should never be used as a cooking or eating utensil.

Waterproof paint increases the longevity of goods.

Most of the time, a waterproof paint surface not only increases the beauty and versatility of an object but also protects the surface underneath from environmental damage. This is another reason why painting the surfaces you use outdoors is a very good idea.

In turn, this increases the life of any object and makes them more durable in situations of routine usage.

Waterproof paint can be used on diverse tools.

You can use one set of acrylic paint on several different surfaces. This means as soon as you learn how to waterproof your painted surface, you can use that same technique or same materials everywhere.

Is acrylic paint waterproof?

The short answer to that question is, no, acrylic paint is not waterproof.

Acrylic paint, by nature, has some degree of water resistance. This saves them from accidental exposure to water once in a while. But, even in such cases, acrylic paint typically will fade when water exposes it.

The nature of acrylic is synthetic. However, even when an acrylic paint hue has dried and cured, water often used as a painting base for latex-based acrylic paints will continue to affect it. Every time they come in contact that is.

If we compare them both, it will be fair to say that oil-based acrylic paint is more suitable for products frequently exposed to water than latex-based paint. Oil-based acrylic is usually considered a better option for items intended to undergo rough use.

But it is important to note that even oil-based acrylic paints will not last that long when frequently exposed to moisture.

How to correctly paint waterproof acrylic paint?

This article segment is dedicated to assessing the various steps that can promise a perfect waterproof acrylic paint coating on any required surface. Here is how to correctly paint any surface with acrylic paint and have it stay for a long time.

Preparing the surface

Later in this article, we discussed how different surfaces respond to acrylic paint and how they can be waterproofed. The fact is acrylic paint sticks better on surfaces that are porous and rough in texture. This means very smooth and non-porous surfaces must be sanded before the painting begins.

Another important aspect of preparing a surface is thoroughly cleaning it. Especially, surfaces with uneven structures need to be cleaned and standard down properly for an evened-out result.


The more nonresponsive a surface is to acrylic paint, the more it is important to apply a good layer of primer beforehand. Surfaces like old wood or canvas shoes do not really require a primer unless you wish to add it.

Other surfaces like glass or plastic cannot do without a liberal amount of primer. The best way to apply primer is through thin layers and double coating. Remember to wait for the primer to drive before you start with the second coat.

Paint the surface

It is now time to paint the surface. Painting the surface is a relatively simple task, and its complexity depends totally on the designs chosen by the creator. Always remember the correct kind of paint and good tools can make the painting process easier and give the best results.

Apply the sealant

When it comes to waterproofing, nothing is more important than this step. Apply a slow and double coat of sealant. Choose a correct sealant, especially for the surface and conditions you are working with.

Allow the sealant to cure as well. Choosing the right sealant can make a huge difference regarding your waterproof acrylic painted surface. Objects like glass and ceramic respond well to being baked on the surface before sealing. This should be done very carefully.

Sealant usually consists of resins or hardeners, making them non-porous to water. Often they also have an oil base which creates a further barrier between the paint and the external moisture. An oil-based sealant is more durable than a water-based one.

You will also find in the market something known as a spray varnish. Spray varnish is a varnish created for beginners and is a lot easier to use due to its uniform application. However, this effectiveness is not as an oil- or water-based varnish.

Some natural everyday products sometimes provide water resistance to an acrylic paint surface area.
