How to Prep Kitchen Cabinets for Vinyl Wrap
Ask any professional installer why a wrap failed and the answer is almost always the same: bad prep. The wrap itself is the easy part: the prep is what makes it last. Skip it and your film peels within weeks; do it right and it lasts years.
DIYer? This is the exact prep sequence the pros use. Follow it in order.

Why prep matters more than the wrap
Vinyl film is a cosmetic skin: it conforms to whatever is under it and only sticks to what it can grip. Kitchens are coated in invisible aerosolized cooking grease, and film will not bond to grease, gloss, or bare porous MDF. Every peeling-corner horror story traces back to a step below being skipped.
What you'll need
- TSP (trisodium phosphate): heavy-duty degreaser.
- Sandpaper: ~220-grit for scuffing and smoothing filler/sealer.
- Spackle or glazing putty: to fill dents and gouges.
- Zinsser Gardz: a problem-surface sealer for raw MDF.
- 3M Primer 94 : adhesion promoter for edges and grooves.
- Alcohol + lint-free rags: final clean. A bundled application kit covers the squeegee, knife and heat gun you'll need next.
Step-by-step prep
Step 1: Remove and label everything
Take off all doors, drawers and hardware. Label each with tape so it goes back exactly where it came from: wrapped doors add a hair of thickness and you'll want the originals in their original spots.
Step 2: Degrease with TSP (don't skip this)
Scrub every door, drawer front, and the boxes still on the wall with TSP. This is the single most-skipped step and the number-one cause of peeling. If the surface still feels slick or filmy, degrease again.
Step 3: Repair dents, then sand level
Fill dents, gouges and open grain with spackle or glazing putty, let it cure, and sand flat. Any bump or hollow telegraphs right through the film once it's on. Then lightly scuff glossy or slick surfaces with 220-grit so the film has something to grab.
Step 4: Seal raw MDF with Gardz
Bare MDF is too porous to wrap well. Roll on two coats of Zinsser Gardz to lock it into a smooth, sealed surface, then sand smooth with 220-grit. (Solid wood and laminate usually don't need this: just clean and scuff.)
Step 5: Clean, then prime the edges
Wipe everything down with an alcohol-and-water mix and a lint-free rag so no dust or residue is left. Then apply a thin coat of 3M Primer 94 to the outer edges, any inner frame grooves, and the back perimeter: everywhere the film wraps around and terminates. This is what keeps edges from lifting later.
This is the tedious part. Degreasing, filling, sanding and priming a full kitchen is hours of messy work before a single door gets wrapped. In Houston? Let our installer handle prep and install start to finish.

Frequently asked questions
Do I have to sand cabinets before wrapping?
You don't need to sand to bare wood, but scuff glossy/slick surfaces so the film grips, and sand any filler or Gardz-sealed MDF smooth. The bigger musts are degreasing and priming the edges.
What's the best degreaser for cabinet prep?
TSP (trisodium phosphate) is the standard heavy-duty kitchen degreaser. Follow it with an alcohol-and-water wipe and a lint-free rag before wrapping.
Do I need primer to wrap cabinets?
For the edges, corners and grooves: yes. 3M Primer 94 is the single biggest thing that stops the film lifting where it's stretched tightest.
