2K cabinet painting, sprayed in your house.
REDUX Paint and Fine Finish is a residential painting company in Glendale, WI that sprays Renner Aquaris — a waterborne two-component (2K) catalyzed polyurethane — on kitchen cabinets, front doors and millwork across Milwaukee’s North Shore.
The short answer
Yes — we use Renner, and we spray 2K. Here is exactly what that means, what it is worth, and when we would tell you to skip it.
- The product: Renner Aquaris, a waterborne two-component catalyzed polyurethane.
- What it goes on: kitchen cabinets, front doors and entryways, built-ins and millwork.
- Where: homes across Glendale, Whitefish Bay, Shorewood, Fox Point, Bayside, Mequon, Wauwatosa and Milwaukee.
- Our standard spec: Sherwin-Williams Emerald Urethane Trim Enamel, sprayed. The 2K is the step above it, not the default.
- How it is sprayed: in a portable booth we set up inside your house. Nothing goes to a shop.
What "2K" actually means
Two components. Ordinary paint arrives in one can and hardens by drying — the water or solvent leaves, and the film is what stays behind. A 2K coating arrives as two parts, a resin and a hardener, mixed immediately before it is sprayed. It does not really dry. The two parts react with each other, and the film forms by chemical reaction.
Everything else follows from that. A film built by a reaction ends up denser and harder than one built by evaporation — the same principle as two-part epoxy against ordinary glue. One sets because it has changed, the other because it has dried. The longer version, including the honest case for not bothering, is in what is a 2K finish.
Why Renner Aquaris in particular
Renner is an Italian wood-coatings manufacturer. Its products are formulated for furniture and cabinet production — the industrial end of wood finishing — rather than for the shelf in a paint store. Aquaris is its waterborne line.
The waterborne part matters more than the name does. Most catalyzed coatings are solvent-based. That is workable in a factory with proper extraction and a genuinely poor idea in a kitchen somebody is living in. A waterborne 2K gives you the chemical cure without filling the house with solvent fumes, which is what makes it usable on site at all.
So the reason we can offer this is not that we found an exotic coating. It is that a waterborne catalyzed product plus a booth we carry to the job makes a factory-type finish possible in an occupied house. Very few refinishers are set up for both halves of that.
Cabinet painting with a 2K finish — and what else we spray it on
Kitchen cabinets. Doors and drawer fronts come off, get sprayed flat in the booth, and go back on your existing boxes with the hardware and layout unchanged. This is where 2K earns its money most often — the failures you actually see on a kitchen are at the edges people push, the drawer fronts that take a knee, and the doors beside the range that get wiped hardest.
Front doors and entryways. Here the argument turns on sun rather than wear. On a south or west elevation a catalyzed film holds up better to the exposure. Sidelights, transoms, jambs and casing get the same treatment as the door.
Built-ins and millwork. Mantels, bookcases, handrails and furniture — anything where a sprayed finish reads as part of the house rather than as paint on top of it.
When we would talk you out of it
2K costs more, has a working window once the two parts are mixed, and is harder to touch up years later because a cured film is difficult to blend into. Those trade-offs are real, and there are jobs where they are not worth paying for.
A kitchen that gets ordinary use. Two adults, normal cooking, cabinets that get wiped rather than scrubbed. A properly prepared and sprayed standard enamel will outlast your patience with the color.
A kitchen you expect to change. If a layout change or a move is on the horizon within a few years, you are buying durability you will not be around to collect.
Cabinets that are not worth it. If the boxes are water-damaged or the doors are delaminating, no coating fixes that, and we will say so.
The preparation underneath matters far more than which of the two coatings you pick — which is the real reason painted cabinets chip.
What we spray when it is not 2K
Our standard is Sherwin-Williams Emerald Urethane Trim Enamel, sprayed. It cures close to the hardness of an old oil enamel, cleans up with water, and does not yellow on a white cabinet the way oil does. It is what most kitchens get, and it is not a consolation prize.
We quote both at the walkthrough and give you a straight recommendation for your kitchen rather than the more expensive one by default. The 1-year written warranty applies either way.

Renner and 2K, answered directly
What does 2K cabinet painting cost?
The 2K upgrade is quoted as its own line on the estimate, alongside the standard Sherwin-Williams Emerald specification, so you can see exactly what it adds before deciding. Cabinet painting itself starts at $2,500 for smaller kitchens — see what cabinet painting costs in Milwaukee for what moves that number.
Do you actually use Renner paint?
Yes. We spray Renner Aquaris, a waterborne two-component (2K) catalyzed polyurethane, on cabinets, doors and millwork where the job calls for it. It is an upgrade rather than our default — most kitchens get Sherwin-Williams Emerald Urethane Trim Enamel, sprayed — and we quote both so you can see the difference before you choose.
What is Renner Aquaris?
Renner is an Italian wood-coatings manufacturer whose products are made for furniture and cabinet production rather than sold off a paint-store shelf. Aquaris is its waterborne line. The version we spray is a two-component catalyzed polyurethane: a resin and a hardener, mixed immediately before spraying, that forms its film by chemical reaction instead of by drying.
Are you a residential painter that uses 2K paint?
Yes. REDUX Paint and Fine Finish is a residential painting and wood-finishing company in Glendale, WI, and 2K catalyzed finishes are part of what we offer on cabinets, front doors and built-in millwork. We work in homes across Milwaukee’s North Shore.
Can a 2K finish really be sprayed inside an occupied house?
This one can, and that is the point of a waterborne 2K. Most catalyzed coatings are solvent-based, which is manageable in a factory with extraction and a bad idea in a house someone is living in. We bring a portable spray booth, set it up on site, and spray the doors and fronts flat in filtered air. Nothing leaves your home.
Why do so few painters offer a 2K finish?
Two reasons, and neither is that the coating is exotic. It needs a booth — clean, still, controlled air that an occupied kitchen does not have — and the solvent-based versions are unpleasant to use in an occupied house. Being set up for both is the unusual part, which is why 2K has historically belonged to cabinet factories rather than to refinishers.
Does choosing the 2K upgrade change my warranty?
No. The 1-year written warranty on all work applies either way. The 2K is a harder finish, not a different promise.
Do I have to take the 2K option?
No, and on plenty of kitchens we will tell you not to. A properly prepared and sprayed standard enamel is genuinely hard-wearing and it is what most jobs get. 2K earns its cost on cabinets that take a beating. We would rather talk you out of it at the walkthrough than sell it to you.
Where do you spray Renner 2K finishes?
Across Milwaukee’s North Shore — Glendale, River Hills, Brown Deer, Whitefish Bay, Shorewood, Fox Point, Bayside, Mequon, Thiensville, Milwaukee, Wauwatosa, Menomonee Falls, Germantown, Cedarburg, Grafton, Port Washington, Brookfield, Elm Grove and the surrounding area. We are based in Glendale and work at customers’ homes.
