FAQs

Yes, especially with quality brushes (like sable or natural hair). Leaving a thin layer of soap can help the bristles reform into a sharp point as they dry.

Prepping your paint brush ensures it performs at its best, reduces bristle loss, and allows for smoother application of paint, saving time and effort.

Before using a new paint brush, rinse it in warm water to remove any loose bristles or dust – avoid putting a dry brush into paint.

It’s best to dedicate specific brushes to certain paint types. For example, water-based vs. oil-based, to avoid cross-contamination and ensure the best results. It’s also important to note that some brushes are designed to work best for different paint types.

If your paint brush has hardened, soak it in a suitable cleaner, gently loosening the bristles with a comb or your fingers to restore flexibility.

After cleaning, store your brush flat or hang it by its handle with the bristles facing down to prevent damage and maintain its shape.

Wrap it tightly in cling film or foil and place in the fridge to keep bristles moist and paint workable.

Wrap in foil or cling film to seal in moisture; there's no need to wash between coats if you’ll be using it again within a few hours.

Not for short breaks – you can just wrap and seal. Only wash when you’re switching paint types or finishing for the day.

Clean thoroughly, then use brush soap or conditioner. For stubborn stiffness, dip bristles briefly in warm (not boiling) water and reshape.

Clean after every use, reshape bristles, and store flat or hanging with bristles protected.

Rinse and then work a tiny bit of brush soap into the bristles. While still soapy, reshape the tip manually and let it dry with the soap in it, as this helps form and sustain a sharp point.

Yes. Leaving the bristles pointed down for even a few minutes can bend and permanently damage them. Instead, swish the brush gently, dry it with a light twist on a paper towel, and set it flat or horizontally to dry.

Absolutely. Applying too much pressure can splay or damage the bristles. Instead of pushing, pull or drag the brush lightly, as gentle strokes help preserve the fine tip.

  • Always keep paint out of the ferrule to avoid stiffening.
  • Avoid soaking brushes for extended periods, as it weakens the adhesive.
  • For synthetic bristles that have bent, dip briefly in hot (not boiling) water to restore shape.
  • Store brushes in a cool, dry place, away from direct heat.
