I just noticed that all my granite countertops are supported with 'pressboard' underneath them!? Call me crazy, but isn't having pressboard under these counters a bit stupid? I'd imagine it won't take long for pressboard to start rotting out?
What material do you folks have under your counters to support them?

This house had marine ply under laminate (3/4") that held up well, the cabinets weren't backed & let every critter imaginable in, so we got rid of the cabinets, but are still using just the counter top while we think of what to have next... but think the marine ply is the way to go to support the finish counter surface.. (granite tiles usually have the 1/2 tilebacker like hardibacker)

I think you're right Carey. Having pressboard under Granite counters is just ludicrous in my opinion! But from my understanding, this is a common practise among Big Isle carpenters?

If a cabinet maker is using pressboard in the cabinets made on this island the cabinet maker won't have any repeat business nor be in business very long when all the cabinets start falling apart!
There are several different types of made up wood, pressboard, particleboard, MDO, plywood, etc., and some hold up much better than others. When I make cabinets, the weight bearing members (legs) are always solid sawn lumber, but that's just me.

Hey Beachboy,
I thought you gave up on this forum last week, how come you're still posting?[8]

Marine plywood is expensive.
The first bit of water that touches the "pressboard" is gonna make it crumble too. Just hope it's sealed right and maybe you can get by for a few years.

if one doesn't go with Marine Plywood what the sense of getting granite counters???? Anyway, I need something better than pressboard! I mean what would make a builder to use pressboard,(cost)?

All plywood for countertops should be 5/8 inch so when the bullnose comes down there is no subtop line visible- no need for marine grade as the granite is sealed to the subtop- anyone who needs professional, affordable granite work done, let me know-- I have been doing it here on the big island for many years and have cut, fabricated and installed granite and marble in the majority of homes on this side.

do you recommend having the granite sealed every so often?

kani-lehua,
Yes, it is recommended that you do this periodically to protect the surface from stains. The material is actually porous and can absorb stuff if not properly sealed. This is particularly important if you have light-colored granite.
We seal ours once a year.
