Have you ever wondered why your acrylic paint cracks? Cracking can be a frustrating issue that many artists encounter, but the good news is that it can be prevented! Understanding the causes of cracking and implementing the right techniques can help you achieve beautiful, crack-free artwork.
Cracking in acrylic paint occurs when the top layer dries faster than the underlying layers, creating tension that eventually leads to cracks. But fear not, there are several steps you can take to prevent this from happening.
First, it’s important to reduce the amount of water in your paint mix. Adding too much water weakens the binder of the paint, making it more prone to cracking. Try to limit the water content to no more than 30%, or even better, use a pouring medium instead. Pouring mediums help maintain the integrity of the paint while achieving the desired fluidity.
Another crucial factor in preventing cracking is using proper acrylic mediums. These mediums provide additional binders and improve the adhesive qualities of the paint. From gels to pouring mediums, there are various options available to suit your specific needs.

Investing in high-quality paints is also essential. Brands like Winsor and Newton, Daler Rowney, Golden, and Liquitex offer superior pigments and stronger binders, making them less prone to cracking. Avoid cheap white paints, as they often have a higher binder content and inferior quality.
In addition to paint and mediums, environmental factors play a role in preventing cracking. Controlling the temperature and humidity in your workspace is important. Aim for a temperature between 65°F-75°F (18°C-24°C) and a relative humidity above 50%. Avoid air drafts from fans or air conditioning vents, as they can cause the top layer to dry too quickly and result in cracks.
Lastly, proper varnishing techniques are crucial for preventing cracking. Make sure to wait until your artwork is completely dry before applying varnish. Rushing this step can trap moisture and lead to tension build-up and subsequent cracking. Allow your painting to dry for at least three to four days before varnishing to ensure a fully cured surface. Following these techniques will help preserve your artwork and protect it from unwanted cracks.
