Not Happy With Gap On Trex With Plastic Trex Fastner....


We are building our first trex deck. I build a bunch of IPE decks and this is my first composite. We are using pre-grooved Trex Transcents and we ordered the trex plastic hidden fastner. We put the first few boards down today and we are not happy with the 1/4 gap that the plastic clips leave. Will the trex stainless clips leave less of a gap? Or is a 1/4" gap needed since it is 35* out and the decking will expand in the summer?


Thoughts?

Yup you need the gap. At the show in Chicago they had 1/4" or greater gaps on herring bones, but joints, etc. I quit using Trex in 07.
This is my first year with fiberon and as far as I am concerned its the best decking on the planet. 25 years on the finish, no fade, gives all the appearance of the South American wood and none of the work.

You need the gap. It's amazing how much composites move.

Also, if you were installing in warmer weather - I think they have a different spacing requirement - maybe 1/8 as opposed to 1/4? Not sure on the numbers but I know the spacing is different depending on the temperature.

Trex expands mostly along it's length, not width.

Here are a couple that we did this year with Trex Transcends. The Trex clips are easy to install and the gap is nice and even.
