Well this is new for me, I normally answer questions.
I have just finished the framing stage of a 8x5m pergola out the back of my place. It has an angled metal deck roof with a level gyprock(or similar) ceiling below. I am going to clad the two sides of the pergola with James Hardie Primeline weather boards as we already have them on the front of out house.
My question, can you use a plastic corner bead and set up to it with the prime line boards??
I will be running FC sheeting on the inside and bottom of my 250x90 side beams and the Primeline will then run up the outside to the roof. I would like to set the two bottom corners.
