Question Best caulk for trim / nail holes

I have issues with excessive shrinkage of caulk. It is especially frustrating on nail holes. You apply the caulk, remove the excess and it looks perfect. You come back the next day and the nail holes show again as the caulk has shrinked significantly.

I have been using a dynaflex caulk but need to try something else (with lower shrinkage). I have also tried an acrylic caulk before but found it difficult to work with because of the fast dry time.

Any suggestions/comments are welcome.

I use the AlexPlus white paintable caulk.

Alex plus for caulking. Nails holes aren't caulking. Use Window glazing compound. It doesn't shrink. However, I am delving into an area not my expertise. Marksr will chime in when he wakes up.

Personally I wouldn't use alex plus - it's one of the cheaper latex caulks and has performance that coincides with the price

Caulking is only for where 2 pieces of wood [or most any material] meet. It should never be used to fill nail holes on interior woodwork. Painter's putty is for filling nail holes, window glazing will also work. I prefer to use SWP's 66 Glazing because it's not as oily as most painter's putty and I only need to stock 1 can on the truck instead of 2

The correct way to putty nail holes is to push the putty in the hole with a twisting motion and then go across it with a putty knife to smooth it out. I usually use my thumb instead of a putty knife - it's quicker

Thanks for the tips.

Follow-up question: how long do you wait after applying the glaze before priming/painting?

You can paint over putty or glazing almost immediately but it might bleed thru latex paint. 4 hrs or so usually works well.
