Why most cabinet painters use the wrong primer (and how to tell)

We use Zinsser BIN shellac primer on every cabinet job. It blocks stains, sticks to previously finished surfaces, and gives the catalyzed lacquer a perfect base. Many painters use Kilz or a generic bonding primer — they work on some surfaces but not on the variety of factory finishes we see on kitchen and bathroom cabinets. If your painter can’t name the primer and explain why it’s right for your cabinets, ask. The wrong primer leads to peeling within months.

What makes BIN the right choice

BIN is shellac-based. It seals knots, tannins, and old finish so they don’t bleed through. It also adheres to thermofoil (we don’t paint thermofoil — we’ll explain why in another post), laminate, and previously painted cabinets. We don’t use Kilz for cabinets because it’s not designed for the same range of substrates. On walls, different story; on cabinets, we stick with BIN.

How to tell if your quote is using the right approach

Ask: “What primer do you use on cabinets?” If the answer is vague or “a good bonding primer,” dig deeper. We’re happy to show you the product and explain the full process: BIN, then 320-grit sanding between coats of Renner 2-part catalyzed lacquer. That’s what delivers the 10-year warranty.
