Tired of applying coat after coat to reach the color and coverage you want?


The true secret to maximizing your painting application can be discovered before your load your spray gun or even step foot into the booth. By asking your coating supplier or doing some simple calculations off of most product data sheets, you can find the volume solids of your coating.


For any gallon of paint, there is only a percentage of the coating that remains on your substrate. That is known as your volume solids. The rest of the gallon evaporates, which transform the coating from wet to dry. The wet coating that is first applied shrinks in direct proportion to the volume solids of the paint.


For example, if you spray 6 mils wet and your coating is 50% solids, you end up with 3 mils dry.


This is important to understand when evaluating the adequate amount of paint needed to obtain the coverage and color you desire. It is also helpful when comparing costs and why you can’t always trust the price tag! If a coating has a higher volume solids, it will cover a greater area with fewer coats. That saves labor, time, and can increase your throughput. It might be worth a few extra bucks to pay for that coating versus a cheaper gallon with a lower percentage of volume solids.
