We are currently attempting to install a curved glass block wall in our basement(with the finished side being the convex side). The glass blocks are 4" deep and 8"x8". We intend to have 4 rows of glass block from floor to ceiling.
Now for my problem, they are only available in flat not curves which means we must place the blocks curved. the problem this is creating is an 1 1/2" gap at the front of the convex side and 1/8" gap on the concave side.
I am looking for suggestions on how to effectively make the 1 1/2" gap look like it was meant to be.
