I have been searching the forum for this problem and came across a topic titled " Seeking advice on chipped paint (Hand painted)" The lady that posted this seems to have experienced the same issues as I am. The only difference is that the Helmi 10 is only not bonding to the primer, where as the lady poster seemed to have primer problems too. Okay, some background. I am building my kitchen from Birch ply, Tulip Wood (American Poplar) and MDF for the door faces. Fortunately, I chose to only paint the bottoms of the wall cabinets by way of a test to see if I’m capable of getting a good finish, using some of the methods described on this site. Here is what I did.
- Sanded Birch ply, Applied Zinsser BIN with short nap roller, sanded BIN and applied a second coat. Sanded second coat and applied top coats of Helmi 10. Tack clothes used between all coats.
I am wondering if I might already have the answer to this problem and wondered if you guys might agree? When I applied the Zinsser BIN I sanded it with 240 grit Mirka Arbranet, but because I’m trying so hard to get a flat finish, I sanded the primer so that it was very smooth. It has a polished feel to it. Do you good people think that this is why it scratches off easily, even with a finger nail in places?
Many thanks for any advice given.
