Filling holes
Hello!
Background: We are changing the look of our kitchen by painting our kitchen cabinets. They are currently stained birch. We have cleaned them with TSP, sanded and have applied the first coat of primer. I also want to change from handles (2 holes) on the cabinet doors to knobs (1 hole). Neither hole is in the position I want for the knob.
So, using a non-shrinking wood filler, we filled the holes left when the handles were removed. We overfilled the holes and then sanded them smooth. I felt that you could still feel some indentions, so I overfilled them again and sanded smooth a 2nd time. You could see where the holes were, but there were no indentions that we could feel. Left overnight to dry (as per the instructions) and checked them again this AM. They still felt smooth.
Now, after the first coat of primer has been sprayed on... the filled holes are VERY visible. They appear to have recessed a bit. I am totally confused on how this could have happened as they felt smooth (no indention) this AM before the primer was applied.
Can anyone suggest what we need to do to fix this? Should we just apply more wood filler, re-sand and then try the next coat of primer and see what happens? Could it have anything to do with the stain being on the inside of the hole when it was filled? Anything you can suggest would be most appreciated as we are totally stumped.
TIA!

Yep. Overfill it like you did, use a random orbital sander, as it will cut the bondo down faster.
Make sure you mix the bondo properly and add enough hardner to it. If you lack the amount of hardner it will take a lot longer to dry. For every table spoon of bondo, put a dab of bondo about 1/4"-3/8" long of hardner.
You'll need to play with this and see how fast it's drying, compared to the time you're applying it. If you see you're wasting the bondo because it's drying too fast, then don't add so much hardner.
Sand with 150 grit.

Ok,
Take a table spoon, as in just like the ones you'd use at dinner and scoop out bondo the size of that. Bondo Hardner comes in a tube like toothpaste. Squeeze out the hardner about 1/4" to 3/8" long. Mix the two together until it becomes the same color. Bondo comes in different colors, but the most typical is a gray/greenish color and the hardner is red, thus will make it look pink when you mix it. You'll have to play with it until you get the feel for how long to mix and how much to mix at one time, so you don't waste it.
