HOW TO PERFORM A SCRATCH TEST ON YOUR PAINTED FURNITURE TO TEST ADHESION | QUICK TIP TUESDAY + VIDEO TUTORIAL
Hi, sweet #sifamily! I hope you are well and enjoying this summer weather. I had to take a trip to ER over the weekend for kidney stones…ugggh. It’s been painful so I didn’t get a chance to finish the dresser I was working on. But I didn’t want to leave you empty-handed so I’m throwing it back to our Quick Tip Tuesday (QTT) format and sharing How To Check Paint Adhesion using this simple scratch test. If you’re unfamiliar with the scratch test, this is the BEST way to confirm your freshly painted furniture will not scratch, chip or peel. Because let’s face it, after putting in ALL that work, we want to be confident our gorgeous finish will stay put when using or selling it! 🙂
So here’s what I’m working with. It’s a SUPER boxy and glossy dresser I picked up for $30.

HOW TO PERFORM A SCRATCH TEST
A scratch test is a simple way to ensure your primer or paint has adhered 100%. Once you’re confident your base primer (or paint) has adhered to the furniture, you don’t have to worry about chipping, peeling, or scratching once it has cured and you start using the piece.
I ALWAYS do a scratch test when painting glossy pieces! When I first started painting furniture, I made my fair share of mistakes including skipping this step only to be utterly disappointed when my freshly painted finish started peeling off. All my hard work for not because of course, I wasn’t going to sell a piece like that!
All this is easily avoided by following these steps.
• Clean your piece of grease, grime, and dirt for the best adhesion. I like this cleaner or TSP.
• Once the primer has dried (according to the instructions) perform an adherence scratch test.
Take your nail and scratch the surface with some force. The primer or paint should stay put and NOT come off.
I’ve also used a nail, screw, paint can opener, etc to perform a scratch test. But just a heads up, if you’re using anything made of metal, the metal will leave marks (they look like pencil marks) that you will have to wipe off before painting.
Another good alternate tool is a wood craft stick which doesn’t leave any marks. But I find my fingernail works the best and I always have it handy. 😉
This scratch test works on primer OR paint. For instance, if you’re painting with chalk or chalk mineral paint that suggests NO primer, yet you’re unsure whether the paint will stick to your project, I suggest painting a small inconspicuous area and come back in 24 hours to perform the scratch test. If all is good — paint away! If it scratches off like in the image below, the prep work I listed above is required.
I really hope this is helpful especially if you’re just starting out. If I can save one person from all their hard work from peeling off…this post is well worth it!
I hope you join me this Thursday when I’ll be back with my Furniture Fixer Upper Crew sharing how this dresser all comes together. I still don’t know what I’m going to do with her yet but hopefully, some inspiration will strike soon. 🙂
