All right so I call this place where they sell HDPE but unfortunately they only have 1/4" HDPE. I read that 1/4" would be really thin for counter-sink screws so I was wondering if you guys think I could use some industrial glue to secure the HDPE on my top sheet.
that is what i have. works fine. ditch the liquid nails and just counter sink some outdoor wood srews. works fine. onlything thats a bunner is withough metal edges to the box the edges of the hdpe gets trashed just dont take gnarly falls on it.
Dude, 1/4" is plenty thick for countersinking (I have 1/4" on my box). Maybe put some coping on it if you are really worried. I'm putting coping on my boxes soon.
i tried doing my lexan with "silicon adhesive". i used a decent amount , but it didnt stick for very long and after 1 season i ended up having to re-do it
you could wax it up, then it wont rust but yeah youd probably get more slideage on the metal then on the plastic. but if you slide like mad anyway whats the difference?
i have 1/4 hdpe and counter sunk it and it is fine. no cracks or anything, and it is super sturdy. just countersink barely enough and then sand it over
