Whether or not you need to dilute paint before spraying depends on a few key factors-primarily the type of paint you're using, the model of your sprayer, and the size of the spray tip or nozzle.

Some professional-grade sprayers, such as air-assisted airless systems, are designed to handle thicker paints straight from the tin. On the other hand, smaller handheld sprayers often require the paint to be thinned for smooth and consistent coverage.

When Is Dilution Necessary?

To determine if thinning is required, consider the following:

• Check manufacturer guidelines: Always consult the paint and sprayer manuals for specific dilution recommendations.
• Paint type matters: Thicker paints like emulsion or latex usually need thinning, especially when used with smaller or DIY sprayers.
• Nozzle size: Larger nozzles can handle thicker materials, while smaller tips are better suited to thinner substances like stains or lacquers.
• Test first: Before starting your project, test the spray pattern. If you notice spitting, spluttering, or an uneven fan, your paint may be too thick.

Regardless of whether you're spraying water-based paints like acrylic or oil-based options such as enamel, assessing the correct thinning ratio for your setup will help you achieve a professional finish and prevent issues like blockages, poor atomisation, or overspray.

How to Dilute Paint for a Sprayer

Diluting paint is typically simple, and most paint manufacturers provide clear guidance on how much thinner or water to use. Always follow their instructions-thinning requirements can vary between brands even for similar paint types.

To dilute paint correctly:

• Refer to the paint tin for brand-specific thinning advice.
• Measure carefully, using the correct ratio of water, solvent, or specialist thinner.
• Mix thoroughly to ensure a consistent blend.
• Test before use, and adjust as needed.
