Why Your Bristles Clump Up When You Paint

You likely want to know what you did wrong to end up with clumped paintbrushes. Learning the causes of clumping in paintbrushes will ensure you know what to avoid. Here are the top reasons why bristles cling together despite your best efforts:

1. Paint Drying On The Brush

Leaving your brush with paint on it longer than necessary, e.g., between breaks or failing to clean the brush properly after a painting session. When paint lingers on the brush for too long, it begins drying in between the bristles. Your paintbrushes’ bristles are consequently held in clumps by the dried paint.

2. Paint Building Up on the Brush

Allowing too much paint to build up on the brush will also cause the bristles to clump up. The painting technique discourages repeated dipping of the brush into the paint without cleaning it properly between the different layers. Painters who make the rookie mistake of dipping and painting will likely overload the bristles with more paint than can be applied to the surface. The excess paint will begin to accumulate between the bristles and cause them to clump together.

3. Low-Quality Paintbrush

Using a low-quality paintbrush increases your bristles’ probability of clumping together. Please note that even the most expensive animal hair brushes will certainly clump if used, cleaned, or stored incorrectly. The biggest difference is that the cheap ones may clump even when you do everything right. Cheap paintbrushes clump more often because they are made of substandard synthetic fibers that are often weakly attached to the handle and unevenly spaced. The uneven spacing increases the odds of paint buildup, causing your bristles to clump.

4. Poor Storage

How well you store your paintbrushes greatly affects their overall health. If you store your brushes in a manner that causes the bristles to be bent out of shape or compressed, you increase their chances of clumping when you paint. Always store your brushes facing up and with enough space to avoid compressing the bristles.

5. Poor Cleaning

If you do not clean your brushes after every use, they are likely to clump up due to paint residue drying up between the brushes. Improper cleaning may also leave behind some paint between the brushes, thus clumping. If you do not know how to clean your brushes properly, you will find a section detailing the recommended process within this article.

How to Restore a Clumped-Up Paintbrush

The good news is that you do not need to toss your clumped-up paintbrush in the trash. It is not beyond redemption. We will explain how to soften and recondition bristles that have clumped up or hardened into position.

Mix warm water with a generous amount of good-quality soap. Be sure to use a container that can accommodate the entire length of the brush without compressing the bristles. If your brushes are made of natural fiber, avoid harsh soaps, as they may strip away the bristles’ natural texture. Soak the clumped-up brush in warm soapy water for about fifteen minutes. If the bristles haven’t softened up, mix up some more soapy water and soak the brush again.
Next, put on a pair of rubber gloves and rub your bristles gently. Gloves are important to protect your talented hands from the toxic chemicals that are often present in the paint. Try to work as much soap into the bristles as you can without getting too aggressive with the bristles (we do not want to yank them out of position or bend them out of shape).
After rinsing off most of the paint, you are now ready to soften the brushes in white vinegar. Clean your bowl of soapy water. Fill the bowl with fresh water and add three to five tablespoons of white vinegar. Submerge your brushes into the solution and let them rest for about thirty minutes. Rinse the brush with warm water and feel its texture. If your bristles still haven’t softened, repeat the process until they change in texture. If you want to speed up this process, heat your white vinegar and water solution in the microwave before soaking the brush.
Your bristles should now be much softer. Use a paintbrush comb to brush out any paint particles that may be stubbornly clinging on for dear life between the bristles. Ensure you use a good paintbrush comb to avoid damaging the bristles. Give the brush a good combing through because tiny particles provide a surface for the clumping to begin all over again.
Using a high-quality natural oil or baby lotion to further soften the bristles and increase their flexibility. Use a little bit of oil and massage it into the bristles using a motion similar to that you used to rub in the soapy water. Sparingly add more oil if you need it. After covering the bristles in an even coat of oil, wipe off your brush on a towel using gentle circular motions. Repeat the process until all excess lotion is off and the bristles feel as soft and flexible as you’d like.
After restoring your brush’s flexibility and softness, rinse the brush in warm water to remove any traces of soap or baby lotion. Your job will be done once the water runs clear of any soap bubbles or oil layers.
Place your brush on a dry towel and leave it to dry.

How to Prevent Your Brushes From Clumping Up

Learning how to prevent your paintbrushes from clumping up will save you from spending precious time (where you could have been painting) restoring clumped-up brushes. It will also guarantee that your investment in the brushes is secured by extending their shelf life and preserving their efficiency.

Here are the best ways to prevent your brushes from clumping up:

Be gentle when handling and cleaning. Your brushes bristles are attached o the handle using glue. If you are too rough on the brushes, especially when cleaning them, you risk pulling out or bending some of the bristles. Missing or out-of-shape bristles increase the odds of paint building up on the brush and eventually clumping up the bristles.
Form a habit of cleaning your paintbrushes every time you put them down for more than five minutes. Cleaning a paintbrush is one of those chores that gets infinitely harder the longer you postpone the job. You already know that dry paint is often responsible for clumping, so do not give the paint on your brush any chance to dry on your watch. When cleaning, pay special attention to any paint that may hide out near the base of the brush or in between the bristles. Removing all paint from the brush is the only way to ensure it remains soft and supple after drying.
Dry your brushes properly. You can hang them, lay them flat on a dry towel, or place their handles down in a container. The last option is not recommended because the water drips into the brush’s handle and may cause the glue to weaken or the wood to warp.
Store your brushes properly. After the brushes dry, store them in a container that they fit into. You could also hang them. The rule of thumb is to avoid exerting any pressure that may destroy your bristles.
Invest in high-quality paintbrushes that are less likely to clump.

Clumped paintbrushes are likely to ruin the quality of your paint job. This situation should not ruin your project because it is easy to avoid and can be easily corrected. Investing in high-quality brushes and treating them with tender love and care is the best way to avoid this pesky problem. If you cannot afford to spend a lot of money on brushes, do not worry because even the cheapest brushes will do a pretty good job if you follow the advice we have recommended.
