Re: Finishing Nails
for baseboards i use a 16 gauge nailer with 2"| nails, they have more holding power than a 18 gauge plus the gun is more powerful which means it can sink in thicker mdf or hardwoods used, for thin moldings or 1/4 round i use a 18 gauge nailer.
as spruce mentiond the stitch techique works great when you can only shoot to drywall, i have to do this all the time on steel stud framed walls or icf walls. when i do this i always use construction adhesive or atleast wood glue in combination with 3 nails per fastening point.. painters hate having to fill the extra holes but i simply tell them " you can fill the extra holes now or have to come back in 6 months to recaulk everything to the wall when it pulls away
fire up the saw and make some dust
