I would like to fasten pressure treated (dry) 1 X 2 furring strips to an
unpainted concrete block wall. Is it acceptable to do so with Liquid Nails?
If so, are there any special precautions/steps to be taken?
Bad idea with just liquid nails. Depends on what the furring strips are
Concrete nails, (cut nails) are not that expensive and they will pound in
with just a hammer. I would use 2 to 2.5 inch concrete nails every 12 inches
the length of the furring strip.
Probably to many nails, I am not interested in problems later so I tend to
over kill a bit.
I've used Liquid Nails-like construction adhesives, although mostly
polyurethane-based, successfully in this circumstance when I had no
other options. But I usually use concrete nails and a palm nailer to
give the connection better mechanical fastening. The main problem
is that they're surface adhesives. If the surface isn't completely
clean or the wall might have intermittent moisture problems you could
have trouble later.
