What is a water brush pen?

A water brush pen consists of a nylon brush tip with a barrel that you can put water in. Each water brush has a type of water regulator that when you squeeze the barrel it will cause drops of water to move through the regulator from the barrel to the brush tip. This way you can control the wetness by adding more water to your brush to create a watercolor design.

Features:

Nylon brush tip – the brush tip is made from synthetic nylon. This material is good to use with ink and water. The nylon tip can be stained by color. But you can continue to use it with other colors even though it gets stained. It is a good idea to regularly wash your tip.

Variety of sizes – You can find water brushes in a variety of sizes including large and small. Generally a larger brush is better to make it easier to cover more area, but if you need a fine line a small brush may be preferred.

Different types of Tips – You can usually find water brushes in a brush tip or a flat tip.

Convenient for on the go projects – One benefit of water brush pens is you don’t need a separate water source. Fill up your water brush before you leave the house and you are ready to create fun watercolor projects on the go without needing a separate cup of water.

How to use a Water Brush

First add water to the barrel of your water brush. Depending on the type of water brush you may fill, squeeze or piston the water to fill the barrel.

Next, if you are using a squeeze type water brush you will squeeze the body of the brush to cause water to penetrate through the regulator to wet the nylon brush tips. The more squeeze and added pressure you give, the more water that will flow into the brush. If you squeeze enough you can cause water drops which you can add directly to your watercolor paints, blending pad or onto your paper.

How to clean your Water Brush

It is a good idea to clean your water brush regularly. Using a paper towel continue to wet your water brush and wipe it on the paper towel until all the color has been removed.

Note: since the bristles are made from Nylon it is common to get staining on your water brush. If your water brush stains you can continue to use it with other colors. That color stain won’t affect additional colors you will use with your brush.

If you need to deep clean your water brush then you can take it apart further and clean the various parts with water and dish soap or bleach. Make sure everything dries completely before you assemble your water brush back together.

How to store your Water Brush

When you are done with your water brush make sure you dump out all of the water and let everything dry. Once it has air dried you can reassemble the barrel with the brush. This way you don’t leave the static water in the barrel and less chance of developing mold which is always a possibility when using tools that require water.

This is a good in direct technique for when you want to use your brush pens with watercolor paper. Generally, watercolor paper is too rough and it is best to only use your brush pens on smooth paper. By using the water brush instead you can still benefit from the various colors of your brush pens, but not ruining your brush pen tip.
