Modernising Manual Finishing with the 2K+3K System
We installed a three-pump GRACO 3KS dosing system in the manual finishing room of furniture manufacturer Arens AS, where the output of component A is 25 cc for smaller quantities and continuous tone changes. The system ensures precise mixing, consistent quality and avoids mixed residues, while providing an accurate overview of material consumption. The solution enables automatic expansion of the number of finished tones up to 30 tones.


The project challenge
Unlike the automatic line solution, a manual workstation finishing system must operate with smaller quantities and cope with continuous tone changes within a single day. The management wanted reliable 3K capability – for dosing colorant, hardener and the viscosity adjustment solution. The ability to expand the system in the future was also important.
How we built it
We installed a GRACO 3KS dosing unit in Arens AS's manual finishing room, engineered with flexibility and precision in mind. The low A-component output makes it possible to prepare the next tone during operation or keep the base tones continuously ready for use.
- GRACO 3KS dosing system
- 3 pumps (colorant, hardener, viscosity solution)
- A-component output of only 25 cc for smaller quantities
- automatically expandable up to 30 tones
What we achieved
- precise mixing and reliable finishing quality with every tone change
- time savings on mixing thanks to base tones that are always ready for use
- zero mixed residue – paint quantities can be used up precisely
- an accurate overview of the quantities of material used per job
- scalability up to 30 tones without rebuilding the system

Manual finishing booths with drying tunnel and pump cabinets
For a returning customer, we manufactured wider manual finishing booths with a drying tunnel as well as specialized pump cabinets for paint pumps, into which safety leak trays were integrated. The solution was designed as a 3D model according to the customer's requirements, and in addition to the booths and pump cabinets, we organized all partition walls, doors, and finishing technology. The result was a fast and seamless implementation and a satisfied customer who received exactly the solution they wanted.
Manual finishing department: two paint booths and a drying tunnel
We established a dedicated manual finishing department for a long-term client to produce custom orders. We installed two 3-metre-wide finishing booths, six finishing pumps, a drying tunnel, and in-house manufactured GRINO drying trolleys. To ensure worker safety, we added barriers and fast-opening doors that separate the finishing area from the rest of production. The new department operates flawlessly and successfully fulfils all custom orders.
Renovation of a Door Manufacturer's Finishing Workshop – MAKOR Automatic Line and Manual Finishing Booth
An automatic finishing solution, MAKOR SPRAY & DRY – M, was designed and installed for a Central Estonian door manufacturer, together with a manual finishing booth built by Elister. The heart of the finishing process consisted of GRACO PerformAA automatic paint guns with Merkur-series pumps, and the ventilation was interfaced directly with the Makor system, which detects the operating equipment and adjusts the working modes. The entire system was designed, installed and commissioned into working order precisely during the factory's collective holiday, resulting in an energy-efficient and safe finishing environment.
