While it's technically possible to use any fence paint in a fence sprayer, it's always best to check the manufacturer's instructions before proceeding. Some paints are thicker than others and may not work well in a sprayer, potentially leading to clogs or an uneven application. Ideally, one should opt for paints specifically designed for use in sprayers. These are typically thinner and more viscous, ensuring a smooth, uniform coating when sprayed onto a fence.
