Hi All,

I am planning to build a large deck of about 50 square meters in the next few weeks and have decided on screwing the treated pine decking to TP subfloor using Bremick 10g x 65mm stainless screws.

Reason why I'm screwing it is that a previous deck i did a few years back in the same area i used titadecks and it cupped, lifted and twisted within a year despite numerous coats of Cabots Stain.

Anyways, my question, I am envisaging the same type of movement, it is exposed to the elements in the Vic High Country, and was wondering should i drill a larger pilot hole in the TPO decking to accomodate any movement or just use the 10g Smart-Bit as is.

Also I am planning on covering it with a few coats of RainShield and then a few coats of Cabots Stain ?

Thoughts ?

Thanks Everyone
Buzza
