OK, long story but I am building a new workshop ... put every nail in myself so far .. even put up a standing seam roof myself ... framed, roof on, timer for windows and siding.

Long story but 12 years ago when I was young and dumb, I got talked into pouring a slab with thickened edged (it is insulated and had lots of metal in it).

So, I am looking at the bottom edge ... just an inch or two above grade .... water ... snow ... not good (this is why I wanted a frost wall 12" out of the ground).

I am going to put a "bumper board" around the bottom edge. That way if the lower 12" gets hit by a lawn mower, weed eater , ... or if it has a gets wet and rots, I can just replace that one board. I might even go plastic so if it gets scratched it will be the same color all the way though.

My question .... I would like to seal water out from the bottom say 12" of the shop (before the siding starts). I am thinking I can use bed liner to go onto the cement say an inch or two and up the wall (OSB) say 12"

I used Durabak for a shower floor twice ... worked but a pain to work with. I watched a few videos ... EGC is no longer available in the USA ... Hercules seems to get a decent rating.

Just wanted to know if any of you guys had good or bad experiences with any of these products.

There are a few more pictures (I an not a big social media person) on my facebook page: https://www.facebook.com/VermontCountryWorkshop

Karnak would be much better to use. its main recognized use is roofing tar, but is also used for waterproofing concrete foundations and wood that is going underground.

 

line X would be great but I would need them to come out and spray it on. I was hoping for a DIY roll on of some sort. Thanks

 

Hmmm ... I have used it on a roof ... never thought of it on a wall. Thanks

 

i used to use karnak on 8X8 post base where it went into the ground on pole barn buildings. also used it on the bottom ledger board where in contact with ground. also used it on the concrete side of ledger boards to keep wood to concrete seperate. we have buildings we put up 50 years ago still in like new condition.

 

Awesome ... thanks so much !!!!!! Karnak sounds like it will do the job!

 

just make sure no kids or critters rub against it, it can take a while to form a skin so anything that touches it does not come away covered in black sticky tar.
