I have a piece (cherry and maple) that has a few patches that were repaired with CA glue and sawdust.

I want to finish it with milk paint (the “real” kind, mixed up from powder, not the “milk paint” product that GF sells). Some testing indicates that the milk paint will not adhere to the CA patches, even if I use the “Extra Bond” additive.

So, I’m going to need to do something about those patches – any suggestions?

While I do not have an answer to the CA/milk paint issue, I can say that “real” milk paint from powder is a poor alternative to making your own milk paint by curdling fat free milk into quark using vinegar and adding your own color pigment. Homemade sticks MUCH better IMO.

Wouldn’t shellac be a reasonable interface to apply over the CA. It sticks to about anything and most other finishes stick to it. I must confess I have no personal experience with milk paint, however.

The shellac should work…I’m wondering if it might slightly change the appearance of the milk paint in that spot.

I suppose I could shellac the whole piece? Brush on or spray?

Milk paint doesn’t like to stick to anything but raw wood. I tried it over acrylic wall paint, and it flaked off. But flat acrylic wall paint is a good substitute.
