Anyone have any experience with weatherproofing PSL’s?
Prints call for PSL’s on exterior and to run from interior to exterior.
Treated PSL’s not availbe in my market.
Secondary treatment would require treated wood in interior(all exposed beams) and a trip back to engineer to derate the beams.
Architect provided no details and refuses to acknowledge issue.
Trus Joist won’t/can’t provide any help/advice.
Climate hot and dry (100 degree 12%rh) to -20 with everything inbetween. Snow on ground and thus against columns 2-4 months of the year.
I’m thiking epoxy sealer then uv stable poly?
thompson water sealer and poly?
Any experience that has paid off or things that didn’t work so I don’t have to go down the same path you learned from?
Thanks
Rob

I would not use Thompson's. And you proabably can't put a finish over it.
I would look at some of the Jansco products. They have paintable water repellant protectants.
The protectant is copper or tin oxide based.
The repellant is was, but a low enoug amount that is can be painted over.
Thanks Bill,
Don't know about Jansco, I do know about Jasco.
Great thought I knew about the green and brown stuff and ruled it out for the coloring issue but with your reminder I goggled to check my spelling and found they have a clear version too. yahoo! I'll have to take a test run with it.Robany other ideas out there
I ment Jasco. Don't they say that memory is the first thing to go.Now what are we discussing again.
level,
What you are looking for is Wolmenized PSL as manufactured by Trussjoist. They are PSL beams specifically treated for outdoor applications. I just used them in Boston on a roof deck on a 4 story walk-up to take all the new loads from the deck and transfer them to the exterior masonry bearing walls. Worked out great.
I'm suprised that trussjoist was no help. Where are you that you can't get your hands on these babies?

I'm in the great northwest, on the east side of the cascade mountains in northern Washington. Trussjoist stated to me that the treated version of the PSL is not availble in our market, and they reccomended getting a secondary company to treat the standard PSL's. Treating the PSL's would derate the load so I'd have to go back to the engineer and after all that I'd need to resurface the PSL's as they tend to fuzz out and get ugly in the treating process. I'm not real kean on resurfacing an 7x18 PSl thats 32' long, and I've got more than one!
Lucky you, you've got what I need at your lumber yard,
thanks

any other ideas out there?
Any experience with Dalys ship and shore?
so no other takers?
advice ?
Thanks Rob
I'd think about buying the Wolmanized Trussjoists from a region where they do sell them. If you've got a lumber supplier with a good purchasing agent, they may be able to broker it for you. Higher transportation costs could easily be offset by reduced labor costs.
good thought but our lumber yard won't do it and looking at the website in the next post makes me know why, the nearest dealer is 1200 miles away!
Thanks for the responce

If it were me I'd tend to go with one of the high-end finishes used in the log home industry. At around $100 per gallon, one of of the better finishes won't be cheap, but they are amazingly durable on exposed wood and easy to apply.
The best I've been exposed to is the two-part finish from Sikens. The base layer is thick, moderately soft, bonds well to wood and fills small voids. The second, outter layer is harder than a fingernail and really sticks to the first layer.
Having said that, there are new finishes popping up all the time and there may very well be something that is even better.
