Answer
For laminate countertops before painting, clean first, scuff with 220, then refine with 320.
Why it happens
Laminate countertops are slick and need a clean, dull surface before bonding primer.
Recommended grit
Use 220 to scuff laminate, then 320 for smoother primer prep.
Wet or dry
Dry.
Success check
The countertop is clean, dull, and evenly scuffed.
What to do
- Clean grease and residue from the countertop.
- Scuff the full surface with 220.
- Refine lightly with 320.
- Remove dust before bonding primer.
Avoid: Do not paint over glossy laminate countertop surface.
