Hi fellow renovator's
First time poster here.
I am planning a decking area under my new verandah approx 70m2 and have spent hours trauling this forum seeking advice, ideas and answers. I have most of the info I need but have a few remaining questions I would love some answers too if you have the time.
My wife has fallen in love with 140mm wide Northern Box boards and I have to admit they do look great.
My questions are regarding mainly cupping prevention.
The only 140mm boards I can find (i'm in SA) are 25mm thick and I have read a few people recommend 32mm for wider boards, is it possible to get 32mm Northern Box or is it suitable as it is a very hard timber to go with the 25mm? also it has been suggested that I use 3 screws (I plan on using the spax flat countersunk screws) to prevent cupping is this really neccesary or will 2 be sufficient and does staggering the screws make a long term difference?
Thanks in advance for any replies and a big thanks to the info and effort people go too with there posts!!
