Wagner SuperFinish SF21 - Designed To Suit Your Application
The Wagner SuperFinish SF21 Pro is a true entry level trade machine built for professionals ready to invest in performance and reliability. Compact, efficient, and easy to maintain, it delivers the reliable, consistent spray quality tradespeople expect without the price tag.
The SF21 sits perfectly between DIY sprayers and full scale trade airless sprayers.
Whether you need to take paint straight from the bucket for big jobs, fast colour changes for small applications, or one unit that can do both, the SF21 Pro range makes it simple to pick the right setup for your workflow.
Below we outline the three configurations, the key benefits of each, and who they’re best suited for, so you can get professional, repeatable results on every project.
Understanding The 3 Different SF21 Configurations
The SF21 Pro is a compact, diaphragm pump airless sprayer designed for consistent finishes and low maintenance,.
1/ Flexible Suction
Draws directly from paint pails or drums via a suction hose for continuous output and fewer refills. Ideal for larger areas and open job sites where productivity matters.
Designed for painting larger surfaces like warehouses, farm buildings, roofs, ceilings and walls
Best for: Multi building properties, maintenance contractors and small paint crews who want minimal stops and long hose runs.
2/ 3.7L Hopper
Compact 3.7L gravity fed hopper perfect for small applications and fast colour changes. If you need to spray less than 4L of paint this is the perfect airless sprayer.
Unlike the suction feed this is very efficient with the amount of paint required to complete smaller jobs.
Best for: Joinery and furniture finishers, painting doors, trims, architraves and cabinetry.
3/ Pro 2-in-1
Switch between suction hose and hopper to match each job. One machine that adapts to both volume work and fine finishing.
Best for: Anyone who want maximum flexibility from a single unit providing the ability to do a mix of large areas and detailed projects
