When fitting the pine T&G planking, I made sure that all the T&G was properly inserted, before using my nail gun with 1” brads. OK, I had the problem of the two planks imitating a banana, but that was my fault, however last night I noticed that a number of the planks are trying to twist, and come apart from the T&G, but the brads are holding.
Some people tend to think that brads are more for tacking wood together whilst glue dries, but this has proved that there is some strength in those thin little wires.
I am really disappointed in the quality of the timber, it obviously isn’t just this batch, I have the same problem in the house, where are the upstairs rooms are roofed in the same way, I had thought it was down to bad workmanship, but I have had to revise my thinking on that one, I think it is probably the Colombian way of using just 1/4” planking that is the problem, there is not enough strength in the timber to stop the movement, especially in the heat.
This is something I am going to have to live with, I can’t do anything to change it, I wish in a way I had gone with my second choice of using plywood sheets, or as they call it here triplex, but I guess in time that to, would have started to degrade.
Is there an answer? I’m not sure, but I didn’t find it, and will just have to live with the roof of the gazebo moving in every direction at will. However so far I am very pleased with the performance of the brads!
