Hi there, I’ve been asked to recuse some old plywood trough planters. Being a laminator I immediately thought I’d skin the inside with a layer of CSM and wet out with polyester resin. Then I’d flow coat the inside to give it a glossy appearance and seal from soil and water damage. Would this be alright? Would another resin/Matt system be better for this project?

Cheers

I would suggest looking for a hydrophilic epoxy, like Megapoxy HX. These will bond with any water molecules that are present in the wood, giving a better bond than regular epoxies.

Okay cheers mate. Then I was just going to staple weed fabric to it to protect from soil contact.

Yeh sounds fine, but I think it will depend how far gone the wood is currently. You will need to get rid of any rot, and then seal all exposed areas of wood to ensure further moisture can't get in.

Okay mate. It’s not to wet atm so just looking at a West epoxy system as I can get it through work. I’ll seal all the wood with a coat of resin and laminate inside the through to add a bit of strength.
