adding lattice to the bottom of a deck | hgtv
6. to give the lattice work a cleaner look and get rid of the rough edges and gaps use pressure treated 1x4s to create a frame. cut as many 1x4s as you did 2x4s. if you made a previous cut list you can just use the same measurements to save time and materials. using a narrow-crown stapler to nail the 1x4s over the lattice seams.
