Trex for upper walkway? (by BG [WA]) Posted on: Feb 10, 2019 6:21 AM

I have a six unit L shaped buidling with 3 units on top and 3 on bottom. Currently, the above walkway has outdoor carpet with plywood underneath which is starting to rot. I was trying to think of ideas on how and what to replace it with. Then it occurred to me why not use Trex decking and eliminate the carpet entirely. Anyone know if it's code and will this work and suggestions? Thanks

Is there living space below this area? If so what's going to prevent water from entering?

If there isn't any living space below it, you could install Trex decking. Just keep in mind that the framing should be 12" on center to properly support the decking. --96.237.xx.xx

Yes would be to code. And would last with no maintenance.

Also years ago it really needed 12 OC. Now it is more rigid and just 16 OC is fine.

On a upper balcony. I still have some of the original trex from the about 1995 . And the product has improved a lot since then.

Thank you for replies. On the second floor there is an awning that covers . Below on the first floor is concrete and first floor entrance. I guess I will need to add More joists and go with 20 ft Trex boards. I did hear that sometimes people slip on trex and thatís the only concern --71.201.xxx.xxx

IF the temps drop below freezing it can be slippery. What we call a "black ice" where there is just enough of a frozen layer of water that you can't really see it, yet enough to slip on. Sometimes just a foggy mist before freezing can create it.

We have it on our from steps and are very careful after wet weather when the temps drop. Can't always warn the poor dog to slow down! This can also happen with wood decking, but the trex seems to have it more often. I would think you could put an outdoor runner over the decking which would eliminate the slip factor. --108.4.xxx.xx

When I last installed Trex on an upper landing I first put down galvanized metal covering the support members. "U" shaped metal over the 2" x 8" wood joist. Then I screwed down the TREX over the metal so the supports would last the life of the deck. --47.156.xx.xx

I have Trex on some stairs and the builder did not leave any space between the boards. I guess he figured since it does not expand and contract he didn't need the space. Make sure there is space so the water drains through. --65.188.xxx.xx

I installed used trex/ composite decking for an upper outdoor porch. Same situation where previous owner had ply + carpet. I re-roofed with rubber membrane and installed boards on sleepers that I set on strips of the rubber + asphalt roofing (as required to level sleepers). If your situation requires more elevation gain to level up, look up bison system which is what roof decks are set up with. Not cheap, but the proper item for the task. I don't see how covering the joists with metal strips extends their lifespan if the joists are PT wood. BTW trex does expand a good amount (at least in the NE). Decking needs to be gapped between boards and between ends of boards. --100.2.xx.xxx

Instead of metal strips which could trap moisture, I prefer to use strips of self sealing ice & water membrane to cover the tops of the joists before installing the decking.

I've found that even though most manufacturers say it's OK to install decking perpendicular to joists that are 16" OC, it still tends to sag. Depending upon the outside air temperature we always space the decking at less 3/16". In the winter we space it closer to 5/16" or even 3/8".

On our high end deck we use Cortex plug style fasteners & Fastenmaster Trapease 3 color screws on the rest. --96.237.xx.xx

They sell deck joist tape and is a good idea.

But you can cut your own from ice and water shield. Or even tar paper if on a budget. --73.152.xx.xxx
