Carpentry and Woodworking - Covering up nail holes in trim?

I just installed some baseboard, and I nailed it in using a nail gun and countersunk the nails about 2 mm. What is the best way to cover up those holes so I can paint over them? Caulk? Wood filler? The nails were 1.5" so the actual holes are fairly small.

Thanks for any help.

Use painter's putty to fill the nail holes. Caulking is for the joints and where the base meets the wall.

And caulking will shrink where the painter's putty won't. Mark, what about glazing compound "33" for nail holes. Will it stand up?

Glazing works but most glazings like Dap's 33 tends to be a bit oily and might bleed thru latex enamel. I usually use SWP's 66 glazing, it's formulated different and isn't oily [keeps your fingers cleaner] :D
plus it isn't prone to harden in the can like painter's putty.

Isn't most painter's putty oil-based? And if so, can I still use it on my baseboards that were painted with latex?

Also, I cou;dn't find painter's putty at Lowe's web site. Do they have a similar product there?

Thanks a lot

Yes, painter's putty is oil based but it can be used with good latex enamel. It is possible it will bleed thru some of the cheaper latex paints. I don't know if lowes sells it or not but I do know they don't put all their products on the web site.

I almost always buy my paint/supplies at a paint store [mostly SWP] One of the reasons I like their 66 glazing is because it's formulated different [not oily] and keeps my fingers cleaner:D

With all due respect to painter's putty,I'm not surprised if Lowe's doesn't carry it.Painter's putty has been around a long time as an all around patcher and such but has been replaced by a whole slew of other products on the market.Painter's like it because they only have to carry one can of stuff to do many things.

For the subject of this thread,there are a variety of wood fillers that would fill nail holes in trim well enough to paint over with no issues.Even spackle would likely work.

In the stores I've worked in we carried at any one time exactly two cans of Painter's putty in our inventory.This is because it doesn't turn over fast enough to carry more and not have it harden on the shelf.I'm not knocking it one bit,but there's alternatives all over the place.If the trim is exterior just make sure the product says it can be used outside.Smooth it with your finger or sand if needed then paint well.
