Waterproofing mdf


Recommended Posts

Posted

I resin my boxes either way, and usually end up painting them. Once I am done with them I toss them outside till I can break them down with a sledgehammer and throw them away. Here in MN I have done this to 3 of them in the past 2 years and I must say, each one has sat untouched for a year+ COMPLETELY exposed to all elements and the next year it seemed good enough to use again. FYI

In snowbanks, rained on, in the sun etc.etc.etc.

Keep in mine I resin them, then use rustoleum paint inside and out.

Not sure why you need it water proofed but I doubt it's to have it sit completely outside like mine so if you do what they say I believe it will honestly work, like a blow through not completely sealed it would prolly last a few years or something ya know.

Usually use Steve Meade's Sunflash and then 3 coats of this... (or until the ends of the MDF stop soaking it in)

if you chose resin your best bet is epoxy. polyester resin is not waterproof and does not adhere well to wood...

that being said, epoxy breaks down over time from UV exposure. in which case it would be a good idea to prime/paint or use a gel coat-

but to be technical no resin is 100% waterproof... just varying grades of water resistance....
