New to woodworking and doing first project which is a garden gate. I am using pressurized 2x4 timber for the frame. To join the vertical and horizontal timbers together, I am using the half-lap joint (I am limited to a circular saw and combi drill for my tools).
My question is do I need to treat the newly exposed faces of the timber (I have bought some creocote) before gluing the lap joints together? Or can I just use the glue and ignore the creocote?
I am in the UK so rain and damp is a given for a large part of the year.
