Yet another type of wood, MDF is similar to Masonite in its thinness, but it does have a hard surface.

Acrylic paints are great for painting many things, even objects that will be stored outside, like a birdhouse.
While the paint might stick to your painting surface, if it’s exposed to water before it’s completely dry, the paint will wash off.
This can end up leaving your painting job with missing pieces of paint, and ultimately destroying your painting.

What Is Acrylic Paint?
Acrylic paint is pigment mixed in acrylic polymer emulsion.
But what is acrylic polymer emulsion you might ask.
This is just a fancy term for it being a water-based paint. Acrylic polymer emulsion is also what makes the acrylic paint dry so quickly. Since this paint is water-based, the water will evaporate quickly, which leads to a faster paint drying time.
Why Should I Waterproof My Painting?
Even though acrylic paints will dry quickly and are known for being a “strong” paint that will practically stick to anything, if you don’t waterproof it before it’s dry, your hard work could instantly be destroyed due to a glass of water accidentally spilling on it or even from some raindrops if you’re working outside.
While acrylics are a tough paint, meaning that once they are dry water can’t really harm them, it’s still good to waterproof your painting.
This can be done with a varnish, which is a special type of acrylic gloss.
Does Acrylic Paint Wash Off?
When wet, acrylic paint can be easily removed or washed off with water; however, it becomes water-resistant and more challenging to remove once it dries.
That said, it’s important to note that “water-resistant” is not synonymous with “waterproof.” While acrylic paint is resistant to water, it may not be entirely impervious to it.
For example, if you accidentally spill some wet acrylic paint on your clothes, you can quickly wash it off with water. However, if the paint has dried, you may need a specialized cleaner or rubbing alcohol to remove the stain.
Is Acrylic Paint Waterproof?
Acrylic paint is considered water-resistant once dry, but it’s not completely waterproof. While the dried paint can withstand occasional exposure to water or moisture, it can become damaged if submerged or exposed to water for extended periods.
For instance, if you paint an outdoor mural with acrylic paint, it may hold up well against occasional rain or humidity. However, the paint may eventually break down or become damaged if the artwork is constantly exposed to water or harsh weather conditions.
Factors Affecting the Water Resistance of Acrylic Paint
Several factors can influence the water resistance and overall durability of acrylic paint. These include the quality of the paint, surface preparation, and the presence of a protective sealant.
Quality of Acrylic Paint
Higher-quality acrylic paints typically have a better balance of pigments and binders, which can result in improved water resistance and durability. On the other hand, lower-quality paints may be more susceptible to water damage or fading over time.
As an artist who has experimented with various brands and qualities, I can attest to the noticeable difference in performance between high-quality and low-quality acrylic paints.
Surface Preparation
Proper surface preparation ensures acrylic paint’s longevity and water resistance. Before applying the paint, ensure the surface is clean, dry, and contaminant-free.
If painting on porous surfaces like wood or canvas, it’s a good idea to apply a primer or gesso to seal the surface and prevent paint from being absorbed. My experience has taught me that preparing your surface can save you from headaches down the line.
Protective Sealants
You can apply a protective sealant or varnish over the finished artwork to enhance acrylic paint’s water resistance and durability.
Sealants come in various finishes, such as matte, satin, and gloss, and can provide an extra layer of protection against water, UV rays, and other environmental factors.
However, it’s essential to choose a sealant compatible with acrylic paint and follow the manufacturer’s instructions for proper application. I’ve found that using the right sealant can make all the difference in preserving your artwork.
