To keep acrylic paint free from mold start by ensuring all lids are fully closed. Minor https://fccland.ru/stroitelstvo/73616-kakie-osobennosti-delayut-stroitelstvo-iz-kelo-dolgovechnym-resheniem.html openings can allow humidity and oxygen to enter—creating the optimal setting for mold to spread. Always close the lids firmly, and consider using airtight containers or add a layer of plastic wrap over the opening before tightening the cap.

Store your acrylic paint in a cool, dry place away from direct sunlight and humidity. Cellars and showers are risky due to high moisture levels. Instead, choose a well-ventilated closet in a room with consistent temperature. Never store paints in vehicles on sunny days or adjacent to heat sources, as extreme heat can degrade the emulsion and trigger microbial development.

If you notice any water condensation inside the container, dry the interior thoroughly with a lint-free towel. Trapped water along the edge can drip back into the paint and initiate fungal growth. Maintain a dust-free exterior to avoid accumulating debris from harboring contaminants.

Add minimal water for consistency only if necessary, and blend it evenly. Excess water can dilute the preservatives, making it far more prone to decay. Never leave leftover paint in open palettes for extended time. Store leftovers in sealed mini containers or use sealed wet palettes engineered for water-based media.

When keeping acrylics long-term, consider adding a few drops of distilled water and a trace of flow improver to preserve texture without promoting microbial growth. Certain creators use a a trace of tea tree oil or 70% ethanol to the paint as a organic antimicrobial, but apply minimally and test on a small amount first.

Monitor your paints frequently. When you notice fuzzy growth, unusual color shifts, or a sour smell, it’s almost certainly contaminated. Throw away the spoiled batch and sanitize the jar completely before using it again. Stopping mold is simpler than reversing it, so minimal ongoing attention goes a long distance in preserving your paints.
