Particle Board?

[dmac14]

Is this usable for building a front deck?

I saw one that used it and I thought it would deteriorate and rot really quickly.

 Have done some type of cabinetwork for the better part of 35 years.  NEVER EVER use particle board if it's gonna be anywhere within a couple of miles of any moisture ...

Are you nuts ? Particle board turns into mush when wet. Use exterior grade plywood without knots. This is the same as marine grade plywood . Treat it by the following method. Mix fiberglass resin and dilute it with acetone to a watery consistancy. Brush onto all surfaces and edges. Apply 3 or 4 coats. First coat or two will soak into wood. This will permantely waterproof the wood . Then carpet and go fishing ;D.     Happy fishing.

Thanks guys, how much does a sheet of marine plywood cost?

[bass or bass ?]

You can get exterior grade , good both sides, at Lowe's or Home Depot for @ $35 for a 4X8 sheet. I used 3/4 inch for my boat's deck.     Happy fishing.

Exterior plywood would be better than particle board but still will not last nearly as long as marine grade. You will probably have to get your local lumber yard to get you a price on marine grade.

Marine grade plywood just means the fibers are compressed tighter together, there isn't as much empty space in the board for water to collect. Its alot of money extra for (in my opinion) not alot of extra function. Sure, it will hold up better, but it isn't going to be a cure all. I sealed my deck made of regular plywood with Thompson's Water Sealer and its held up great going into its third season. Let me be the first to tell you, it has been SOAKED! But thats another story... By the way, if your hull is aluminum, the chemicals used in wolminized lumber will bleed out when wet and that mix will eat through aluminum.

I sealed the deck on my Orlando Clipper with Clear Penetrating Epoxy Sealer.  It soaks in better than thinned resin and dries faster.  It is also more expensive.  It is still in good shape after 7 or 8 ? years.  You do need to treat exterior plywood with something.  I have also torn rotted marine plywood out of a ski boat, and seen several other boats where it rotted.

Both marine and exterior plywood use the same adhesive.

You can get plywood with no knots, but will pay a premium for it.  Better to get it with an "A" side, and the other side plugged, touched, and sanded.

While it will not delaminate, it should be sealed to prevent it from absorbing moisture, increasing its weight.

Marine plywood does not have voids.  It should be sealed as well.  Haven't bought any in years, but it cost two to three times as much as a good grade exterior plywood.

For decking, exterior plywood is fine.  For a hull, marine plywood has no substitute.  For interior decking and bulkheads, exterior will do fine.

Particle board even intact has zero structural strength.  It is used as underlayment in homes for carpeting.  High density particle board is used for formica countertops.

Particle board is good for those because it has a smooth uniform surface.  For a boat, never.

From Wikipedia.

Marine plywood is specially treated to resist rotting in a high-moisture environment. Marine plywood is frequently used in the construction of docks and boats. It is much more expensive than standard plywood; costs for a typical 4 foot by 8 foot 1/2 inch thick board is roughly $75 to $100 US or around $2.5 per square foot, which is about three times as expensive as standard plywood.

There are many types of marine plywood using different face woods. However, for a carpeted casting deck, doug fir filled and sanded one side will do the trick. Go to a lumber yard, (not Home Depot - Lowes), and explain what you are doing. They will fill the bill for you.

I built a storage box 3 rd pedestal placement for my Champion several years ago.  I made it from Advantech.  It even has a wax impregnation that prevents rain from damaging or infiltrating the surface.
