To prevent mold growth in stored acrylic paint start by sealing paint jars with no air leaks. Minor openings can allow humidity and oxygen to enter—creating the perfect environment 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 in a shaded, arid location. Basements and bathrooms are risky due to excessive dampness. Select a climate-controlled storage spot in a room with stable ambient heat. Never store paints in vehicles on sunny days or close to heaters, as intense temperatures can break down the paint and encourage mold.

Should you see droplets inside inside the container, remove it right away with a clean, https://domocvet.com/sovety/v-kakoj-czvet-pokrasit-kirpichnyj-dom-podbor-idealnogo-ottenka dry cloth. Dampness around the seal can drip back into the paint and trigger mold. Clean the outside of the container regularly to prevent dirt or residue from attracting mold spores.

Use a small amount of water to thin your paint in moderation, and always mix it thoroughly. Excess water can reduce the paint’s natural defenses, making it far more prone to decay. Avoid letting paint sit uncovered for long periods. Transfer unused paint to small airtight jars or opt for airtight wet palette setups engineered for water-based media.

For extended storage periods, consider supplementing with minimal distilled liquid and a drop of acrylic medium to keep the paint workable without promoting microbial growth. Many painters recommend a a few drops of cinnamon oil or 70% ethanol to the paint as a plant-based inhibitor, but apply minimally and test on a small amount first.

Make routine inspections a habit. If mold appears as绒毛状 patches, unusual color shifts, or a vinegar-like stench, it’s definitely infected. Dispose of moldy pigment and scrub and disinfect the vessel before reusing it. Avoidance beats remediation, so consistent maintenance goes a long way in preserving your paints.
