Is Acrylic Paint Waterproof?

Acrylic paint is not waterproof. It is water-resistant to a certain degree, but it is not waterproof. The reason is simple: acrylics are water soluble. If you use them in an area that gets a lot of moisture, they may start to deteriorate over time.

As a newbie acrylic artist, you may be wondering if acrylic paint is waterproof or not. I can agree that the prospect of working in water with acrylics can seem a little daunting.

Acrylics are considered water-resistant, but not waterproof. Water-based paints typically don’t stand up well when exposed to moisture or water, which is why they’re not typically used in outdoor applications like exterior painting.

In this blog post, I’ll be going over everything you need to know about acrylic paint, how it differs from other forms of acrylics and how to seal it with a varnish or spray .

How Waterproof is Acrylic Paint?

Acrylic paint is not waterproof. It is water-resistant to a certain degree, but it is not waterproof.

Acrylic paint is a versatile medium that can be used in many different ways. However, it is not waterproof. Instead, acrylic paint dries to a resilient surface that can be easily cleaned with soap and water. If you have an acrylic painting that you want to protect from moisture damage, there are some ways that you can do this.

One method involves using a varnish over the top of the acrylic paint layer. This will seal the surface so that it can’t be easily damaged by water or other substances. Another option is to use a protective coating on top of your painting after it has dried completely. This will keep liquids from seeping into your artwork and causing damage.

If you want to keep your painting on display where light exposure is likely, another option is to use UV-resistant varnishes or coatings. These are designed specifically for use with art pieces so they won’t yellow or fade over time like other types of varnish might do

Is Acrylic Paint Waterproof When Dry?

Acrylic paint is water-resistant once dry.

It takes about 24 hours for acrylic paint to dry completely. Acrylic paint dries with a satin finish, which means it has a low luster and can be easily scratched off. Moreso, acrylic paints are made from acrylic polymer emulsions and other additives, like solvents, pigments and fillers.

These emulsions are water-based and dissolve in water. This means that when you brush them onto your paper or canvas, they will wash away easily with water. However, once it dries, the water evaporates from the paint surface leaving behind a hardened shell that protects the color underneath.

If you want to protect your painted surface from damage caused by weather conditions or accidental spills of liquids (like coffee), then you can apply an additional layer of varnish over your artwork to seal it against moisture getting through its surface.

Is Acrylic Paint Permanent?

Acrylic paints are permanent, which means that they will not fade. However, the colors may fade if colors may also fade if they are subjected to heat or high humidity conditions. The best way to protect your acrylic painting from fading is by using a UV protective varnish. This type of varnish prevents any discoloration from occurring and also protects the artwork from dust and dirt.

The down side is that acrylic paints can be removed easily with soap and water.

What Type Of Paint Is Waterproof?

1. Oil- Based Waterproof Paints

Oil-based waterproof paints are made using oil as the base material. They provide excellent protection against water damage and are easy to apply with brushes or rollers. The biggest advantage of using oil for your paints is its durability. Oil paints are extremely durable and last longer than other types of paints because they have a thick consistency that helps them spread evenly over surfaces such as wood or metal without dripping or running down them

2. Waterproof Sealants

Waterproof sealants are designed to create an invisible barrier between two surfaces that prevents water from penetrating them. They can be sprayed on or brushed on depending on your preference and require no drying time before applying any other type of paint over.

Is Acrylic Paint Waterproof for Outdoors?

Acrylic paints are considered water-resistant, but they are not waterproof. Therefore, it is important to do some preparation before using your acrylic paint outdoors. To make acrylic paint waterproof, add a few drops of liquid dish soap, varnish or a sealer.

This will help prevent water from seeping into the paint and causing it to crack or peel away from the surface. It’s best to use exterior grade paints when painting outside because these paints contain more protective ingredients than regular interior paints.

However, if you’re using an interior grade acrylic paint for outdoor projects or want your project to last longer than three months, try adding a UV protectant product like Krylon’s Wet Look Clear Topcoat spray-on product or General Finishes Enduro-VAR II Water Based.

How to Seal Acrylic Paint for Outdoor Use?

1.Acrylic Paint Sealers for Canvas

For canvas paintings, you have two choices: spray sealers and acrylic varnishes. Spray sealers are easier to apply, but they don’t last as long as acrylic varnishes.

2.Spray Sealers

A spray sealer will protect your acrylic painting from moisture, scratches and dust. It’s also easy to apply and dries quickly so you won’t have to wait long before hanging your artwork on display. However, spray sealers don’t give your artwork a glossy finish like an acrylic varnish does. You’ll also notice that they tend to yellow over time, which isn’t good if you’re looking for bright colors in your artwork!

3.Acrylic Varnishes

An acrylic varnish gives the same protection as a spray sealer but adds glossiness, durability and depth to your paintings by reflecting light back into the artwork instead of letting it pass through the painting. It also makes your painting more durable if you intend to display it outside or in an area where it might be exposed to humidity or other damaging elements.


Step 1: Mix the Sealer

Sealers come in a variety of textures and colors. You can use a clear sealer or choose one that matches your color scheme. To make your own mixture, mix equal parts of water-based varnish with acrylic medium or gel medium. Don’t use oil-based products such as linseed oil or tung oil since they can yellow over time when exposed to UV light.

Step 2: Seal Your Painting

Apply this mixture to your acrylic painting using a soft cloth or cotton swab and allow it time to dry completely before applying any additional layers of varnish or other protective coating over the top.

Disadvantages of Acrylic Paint?

Acrylic paints are very versatile, but they do have some disadvantages. Here are some of them:

1. Dries Much Faster

Acrylic paint dries quickly and doesn’t require any type of primer, which is great for artists who want to get started right away. However, this drying time also means that there’s a short window of opportunity to make changes in an acrylic painting. If you decide you don’t like something about your work, it can be difficult to fix once the paint has dried.

2. Acrylic Tend to Crack

If you want to create thick layers of paint, acrylics tend to crack when you try to push them too far into thick paint. This is because the polymerization process creates molecular chains that are bonded together tightly so that they’re harder for water molecules to break apart and wash away when they’re dry.

3.Doesn’t Stick Too Well on Non-porous Surfaces

The biggest disadvantage of acrylic paint is that it doesn’t stick too well on non-porous surfaces. That’s why it’s not a good idea to use acrylics on wood, metal, or glass. You’ll have to seal those surfaces first with a primer or gesso.

4. Hard to Clean on Some Surfaces

Another disadvantage of acrylics is that they can be difficult to clean up once they’re dry. If you spill or drop some paint on your clothing or carpet, it can be hard to get out without causing damage or discoloration. This is especially true if you use oil-based paints, which are much harder to remove than water-based paints like acrylics.

Is Water Based Acrylic Paint Waterproof?

Acrylic paint does not provide a waterproof coat, but it is slightly water-resistant.

The paint does not need to be sealed or cured before exposure to the elements, however, if you are using water-based acrylic paint on a wall, it will eventually wash away with exposure to rain and humidity.

Acrylic paints also contain no solvents, so they do not require ventilation when used indoors; however, you should always wear a respirator when working with this type of paint because it contains volatile organic compounds (VOCs). VOCs are emitted from many different types of products including adhesives, aerosols and spray paints.

Fun Fact: Acrylic paints can also be used on ceramic and metal surfaces.

Is Acrylic Paint Waterproof on Plastic?

The short answer is no, acrylic paint will not be waterproof on plastic. You need to prepare the surface first.

To make acrylic paint waterproof on plastic you need to:

  • Sand down the surface of the plastic so that it’s smooth and free from any scratches or marks.
  • Wash the surface with soap and water, then wipe it dry with a cloth. This removes any dust or grime that may have accumulated on your plastic items.
  • Spray on a primer which will seal in any scratches in your plastics and make them easier to paint over later.
  • Paint your item with acrylic paints using a sponge brush or roller (and don’t forget to use a good quality one!). If you’re using a sponge brush, dip it into some water first before using it so that it doesn’t dry out too quickly while you’re painting your item.
  • Apply a sealant for extra durability and protection.

Is Acrylic Paint Waterproof on Wood?

Acrylic paint is not waterproof on wood. When it comes to painting wood, you’ll have better results using oil-based paints instead of acrylics because they have more flexibility and adhesion.

Acrylic paints are water-based and contain a high percentage of water as part of their makeup. Since water is so prevalent in these types of paints, they can be prone to peeling if exposed to moisture for an extended period of time. A good example would be if you painted the exterior of your home with an acrylic-based paint and then left it out in the rain for several days without covering it up in any way.

Is Acrylic Paint Waterproof on Rocks?

To a certain degree, yes. This means that you can paint rocks near water and they will stay beautiful for a long time. If your rock is going to be exposed to a lot of moisture, consider using a spray sealant over the paint. A spray sealant will protect the acrylic from moisture and make it last longer than just regular acrylic paint.

You can also use oil paints on rocks and metals! Oils are great for outdoor projects because they are very durable and can withstand exposure to rain or snow.

Is Acrylic Paint Waterproof on Fabric?

Acrylic paint can be washed off. It is not water proof on fabric .The paint is water soluble, which means that it will dissolve in water. When you wash acrylic paint off your hands, for example, it washes off with water.

If you were to put acrylic paint on fabric and then wash it with water (or even just leave it sitting in the rain), the paint would wash off easily because it was applied to a porous surface. However, there are ways to make acrylic paints more waterproof than they normally are.

One of these ways is by adding an additive called Liquitex Matte Medium or Golden Heavy Body Gel Gloss Medium to the paint before you use it on a surface like fabric or wood or canvas. This will make the finished product more durable and less likely to stain when exposed to moisture.

Frequently Asked Questions

Can you seal acrylic paint on fabric?

Absolutely . Acrylic paint is water-based and therefore can be sealed with Mod Podge or a similar product. The sealer will help the paint last longer and reduce fading. If you’re worried about the color, you can also use a clear spray varnish, which won’t darken the color of your project.

Does acrylic paint wash away in rain?

100%. Acrylic paints are water-based and will wash off in rain or with plain water.. With that said, be careful not to let them sit outside overnight.

Final Thoughts

Acrylic paint is certainly more durable than oil paints, not to mention cheaper in terms of cost per ounce.

This means that it is easier to paint large areas with acrylic paints. It is important to note, though, that water-based paints do not prevent mold growth so it’s still best to keep them dry.
