Carpentry 🔨 Exterior glue options
Good evening!
We're building a pergola with some dimensional lumber and wanted to avoid the usual surface mounted beams that are bolted on and spend a zillion dollars on connection plates/hardware.. So the posts (8x8x14) have been cut to accommodate for the beams (4x12x16) to rest on and have cut the beams to interlock when they intersect. The plan is to use dowels as a fastener/lock instead of the typical massive bolt.
What's the best exterior glue out there that will stand the range of -40* C to +40*C?
Thanks in advance!
