INSL-X Stix Acrylic Waterborne Bonding Primer
A urethane-acrylic bonding primer prized for gripping slick surfaces other primers slide off, like tile, PVC, vinyl and glossy trim, making it a go-to for cabinet and trim repaints with water cleanup. It is a bonder, not a stain sealer, so stain and odor blocking is weak, it costs more than general primers, and its 3-4 hour recoat stretches jobs.
| Type | Urethane-acrylic bonding |
|---|---|
| Recoat | 3-4 hrs (full cure 3-4 days) |
| Coverage | ~300-400 sq ft/gal |
| VOC | Low |
| Cleanup | Soap and water |
| Use | Interior/exterior slick surfaces |
KILZ Adhesion High-Bonding Primer
A budget-friendly latex bonding primer that grips hard-to-paint surfaces like Formica, tile, glass, vinyl, metal and glossy paint, recoating in about an hour with soap-and-water cleanup. It is built for adhesion, not hiding: coverage is lower at roughly 300 sq ft per gallon, its thin body needs even application, and stain blocking is minimal.
| Type | Bonding (latex) |
|---|---|
| Recoat | 1 hr |
| Coverage | ~75-100 sq ft/qt |
| VOC | Low |
| Cleanup | Soap and water |
| Use | Interior & exterior |
Our verdict
Stix is the premium pick: superior grip on the slickest surfaces and a smoother base for cabinet and trim topcoats, at a higher price and a longer 3-4 hour recoat. KILZ Adhesion costs less, recoats in an hour, and bonds well for most laminate and glossy jobs — its weaknesses are lower coverage and a thinner body. For showcase cabinets, pay for Stix; for general slick-surface bonding on a budget, KILZ Adhesion is the value choice.
