Some Tips and Suggestions:

Here are some tips and suggestions we have given on how to make acrylic paint waterproof.

  1. Make the paint waterproof, and you won’t have to worry about it vanishing when using watercolors or even just water. Instead, you can use a matte finish varnish after the paint has dried, seal with Mod Podge for a glossier look, or spray-paint with an acrylic sealer.
  2. Mod Podge is not recommended as a sealer for correct permanency and durability because acrylic paint is water-based.
  3. You can use Liquitex Acrylic Varnish if you are looking for long-term protection of your work. This product comes in gloss or matte finish options. However, it does tend to yellow over time if the atmosphere contains high levels of sulfur.
  4. Gloss medium, watercolor gloss gels, or acrylic glaze will all give your paintings a high-gloss finish.
  5. Acrylic paint is resistant to smudging and water, but it can be removed simply by soap and warm water.
  6. If you want the colors in your painting to stay bright, choose acrylic artists’ paint. On the other hand, if you want your painting to have more muted colors, watercolor is the best choice.

6 Common Mistakes You Should Avoid When Waterproofing Acrylic Paint:

If you want the colors in your painting to stay bright, choose acrylic artists' paint. On the other hand,

The painting’s not so hard, but sometimes it can be frustrating when your painting won’t look the way you want it to. Waterproofing acrylic paint is super easy, but there are still a few mistakes that people tend to make while it is about how to make acrylic paint waterproof. Here are six common mistakes that you should avoid when waterproofing acrylic paint:

1. Forgetting to use a sealant:

Waterproofing acrylic paint is all about creating an impenetrable barrier on top of the paint.  To do so, you must use some sealant over it after it has thoroughly dried. I usually use a spray sealant. But you can also use a wax-based paint sealer, which is good for providing water protection to porous surfaces. Then there are the traditional products such as Varathane and Minwax that do the same thing. Waterproofing is not only used to protect your hard work from outside elements, but also to keep it looking its best inside.

2. Using too much water in your mixture:

If you’re going to use water when mixing your acrylic paint, be sure to add very little so that the consistency is almost like pancake batter. Excess water will cause the color of the paint will become lighter and less vibrant. You can also add a drop or two of liquid acrylic retarder to your water, this will slow down the drying time and allow you to use the same piece of art for weeks.

3. Mixing in too much paint or sealant at once:

Creating a thicker mixture will increase your chances of having a more even consistency, but there is a risk that the combination might dry too quickly. Make sure to mix in each additional ingredient slowly and with caution. In any event, you should expect to mix your mortar for at least 20 minutes. It is also a good idea to use a large flat surface such as a tarp that you can work on later. The more surface area you have, the less the chance of unevenness. Try working on a large piece of cardboard in your garage. If you need to stop working before you are finished, wrap it up and leave it so you can continue later.

4. Not coating both sides evenly:

This might be difficult when using watercolors, but you want to coat both sides if possible to halve the drying time. If you’re struggling with this, try using a paintbrush and dipping it in the sealant once it’s mixed before painting over your picture.

5. Failing to give it enough time to dry:

Once you’ve applied your waterproofing mixture and given it time to dry, be sure that the painted area is arid before exposing it to water. Water causes the paint to crack and peel, while the effect is magnified if you’ve used latex-based paint.

6. Cleaning your brushes with soap and hot water:

Give your paintbrushes a break by cleaning them with cold water for easier waterproofing of acrylic paint in the future. Brush cleaner works great for cleaning oil paint brushes. Just use the same soap you use to clean your hands and wash the brush in warm soapy water.
