Automation and technology come to paint prep

Automated stirring systems free up the technician's time for higher-value tasks.

Automated stirring systems  are transforming paint preparation. Manually stirring paint leads to pain points such as inconsistent mixing, and even physical pain points like carpal tunnel syndrome from stirring in circles over-and-over again. That’s not to mention material waste from countless cups, stirring sticks, and wasted paint left in the cups. Shops using automated stirring systems have reported up to a 10% reduction in waste from disposables. 

Along with wasted materials, manual stirring also leads to inconsistent mixes from paint sticking to the bottom and sides of cups, which can contribute to rework being necessary. High-quality painters deserve to spend their time doing what they do best, painting. Automated stirring systems free up the technician's time for higher-value tasks. 

The right automated stirring systems can deliver a fully homogenized paint mix in less than 90 seconds.  

A recent field study of multiple global body shops measured the minutes - and found real results: 

Say the body shop averages six jobs per day. Automated stirring technology saves 3 and a half minutes per job, which totals 21 minutes per day. That yields 10 and a half working days each year that are now free to do other value-added activities, like starting another new repair. Plus, because the color accuracy is better since it is so well mixed, it is calculated that 3.5 days are saved by avoiding rework – which subsequently results in 14 working calendar days saved per year. 

An integrated solution

A stirring device integrated with the spraying cup is designed and tested together to deliver consistent results. A bonus is a cup system designed with indented sides. The sides will then act as a “propeller” to completely and fully mix the paint. Also important, having one lid that fits all cup sizes, to make the technician’s life easier and cut down on waste. And, to save time, use a cup that connects to the spray gun. 

Manual stirring may seem like a minor task, but its impact adds up. Recent advancements in automation make manual stirring (and stirring, stirring, and more stirring) a thing of the past. 

In today’s collision repair landscape, efficiency is no longer just an operational goal — it’s a competitive advantage. Shops that embrace smarter tools, advanced materials, and automated processes, position themselves to deliver faster cycle times, higher-quality repairs, and stronger profitability.
