Re: water proofing marine plywood that will be covered with marine vinyl??
to the op......please read this again......it is correct.......if you glass it with poly.....you cant staple it...
epoxy is just as tough.......thats why all boats are not coated with anything.
you might just do a quick paint job on it if you are worried.....
btw........ marine grade is a really expencive wood for that duty
Actually.. I can staple into Marine grade PL with a layer of mat with my Bostitch
. Its just takes more time to 45 deg tack to set it. ( I am NO PRO on upholstery in any means ). Marine grade IS the best for bulsters and seats unless your going to resin coat the Crap out of them ( epoxy or poly ).
Well I'm no Pro but I epoxied the ext. grade plywood on my seats and I had no problem stapling my upholstery. I used a cheapo HF air stapler set @ 30lbs air pressure and never missed a beat and never bent a single staple even going thru 4 layers of vinyl at times. Maybe I was just lucky. I do realize that where the staples penetrated that will allow the possibility of water penetration but overall coating the wood had more benefit than not doing it. I would be interested in learning why coating the wood is not recommended by upholsterers for stapling.
Ditto Woody
. Remember though that the pros normally "tack" there stuff before full face staples go in. They have to pull them out ... that is why I recommended he Talked to Her about it first. It might be better For Her to "dry fit" before slapping coatings on the wood ( making Her job easier without any coatings ).
usually,,,,,with poly and glass,,,,the barrier is really hard for a staple to go thru.....epoxy alone is different....i dont use the stuff si i dont know how hard it is to go thru with a few coats......
and woodie.......i agree.....so what if the staples penetrate the wood...(i have heard that arguement lots). it will last far longer the way you did it bud.
You kinda have to staple into the wood when doing this .. I dont understand the argument aside from the Top of the line pros that use MG ply instead of CDX or some crap that the staples ( after the bolster or seat was cut ) dont stick because there into Voids in the wood.. then leach out and start to delam the vinyl ..
I upholstered my cockpit side panels after coating them (1/2" marine ply) with one light coat of epoxy. I just used an Arrow hand stapler and SS T-50 staples through foam and vinyl. Then I lightly tapped the few that weren't flush with an auto body palm hammer I bought for $8 at Harbor Freight. No problem. In fact, I had to do an edge again and the staples were very secure.
Good choice IMO .. MGP is the best option for Any Upholster job .. You never know when you use "other materials".
The Other materials can and will work and Im not saying It will not.. its a boat to boat thing again ( and we still do not know the make/model/year of the OP's Boat. We Dont know Interior or exterior .. application .. or nothing.
I say lets keep this civil and not really understanding of the Project at hand from the OP ..I/We are only suspecting at this point.
JDW .. please give us more info and pics please
