My son’s Eagle Scout Project requires him to resurface some outdoor training tables for a charity that provides companionship dogs to vets and those with disabilities. The tables and ramps will be outside permanently, and have to be at least 1/2” thick to support the weight of the dogs. I am trying to decided what the best material to use for this—- obviously MDF is out. I am thinking of using striated flooring board – the type you get at Lowes with the blue edge.

My concern is how to best seal the edges against moisture. The boards will be painted (with several coats of primer), but in my experience the edges is where moisture first gets in. Any suggests as to:

1) What material to use
2) how to seal the edges against rain, etc..

As for the material, I would suggest marine grade plywood, you can’t fimd it at Hd or Lowes usually, you would need to go to a lumberyard. In most cases they need to order it for you. Not sure on the composition and imbeleive it’s pressure treated as well. Have not used it in may years, back when I lived in NY.

As for the sealing, i am not really sure. If you use a water sealer, paint usually will not adhere well and flake off after a few months or sooner. My recommendation if you can’t find an answer here maybe just a web search or local advise from a trusted business like a lumberyard or sawmill. There is so many products our ther it heard to know, personally I would probably use Drylok waterproofer laytex, this way it will flex with the would during temperature changes. Just my 2 cents.

Try these guys. It is spendy, but the UV protection is supposed to be tops.

You could fiberglass tape the edges as one of the other guys here does on many of his ferry boat projects. – – I intend to do this with patrol boxes with my troop due to the heavy use.

MDO is exterior glue plywood that is used for road signs, but you still have the challenge of sealing the edges. You could use white oak which is very resistant to rotting. If you can find it, black locust will last longer than anything, think fence posts. Good luck!
