Trex

[clawman]

I already own the Trex that I will use as base in my shop. My question is, is there an adhesive that would hold it to the sheetrock. I would rather not drill and screw it on.

As a baseboard? Decking or trim pieces?

Adhesive would hold it on (almost any of the PL/Loctite products), but you would need something to hold it until the adhesive cures. It would also make a mess taking it off. Trim screws wouldn’t need to be pre-drilled, but maybe you have concrete or block behind where it will go and not wood stud?

I used Trex for baseboards. Secured with a finish nailer, happy with results.

Trex and other composites seem to have more movement than I'd be comfortable with unless it was mechanically fastened.

I like this idea, but will elaborate on it by using some adhesive first then a finish nails. My plan is to seal the bottom between Trex and the concrete to seal floor and no water can leak to the lower level of the shop.

The deck at our house is made entirely of Trex, from the decking and posts to the railings and balusters and it does like to "move". The width of the Trex pieces do not seem to change much with moisture like wood does. But the length of the pieces do seem to get longer and shorter depending on the temperature.

This has led to some of the longer deck boards buckling a bit during the summer and then contracting during the winter. Everything is held in place with Trex color matched screws, and it seems like the screws on the ends of the longest boards shear off at the joint between the bottom of the boards and the joists underneath them.

The shorter the Trex pieces are, the less they do this. It only seems to happen on the longest ones.

For that reason, I don't think I would put Trex down using adhesives as it might break the bond and make the boards loose if you don't have some type of mechanical fastener like nails or screws.

The Trex that I used from Home Depot is not flat on the back side. Would require more of a flat surface to glue. Here is my setup for a pole structure. Used strips of foam board on floor so insulation wound not touch the cement. If you wanted to caulk floor I guess it would be fine but I would rather not build that tight. If there was water getting in that wall I would rather see it on the floor sooner than later.

Oh man that's some heavy stuff but tight to the floor will carry most of the weight. I would definitely use some construction/panel adhesive AND a decent sized finish fastener, No 18 ga pop gun

Though I understand you are using it because you already have it on hand I just have comment PVC material would be so much so much lighter
