Self Adhesive UV Masking

I posted this over on CT but maybe some of you finish experts here could help too. Maskijng does after all go hand in hand with it. I'l just copy and paste....

I think you painter guys/gals might be my best bet. Does anyone know of a material that is self adhesive and will stick to bare wood, and will also block UV rays?
I'll tell you why maybe it will help with othr ideas. I'm installing some ERC joists that will be exposed in the bedroom. I'm running them through the planer now. Once I get them up, there will be some lag time before I get the decking and roof on. It doesn't take long for the ERC to turn brown when exposed to the sun. Hours only.
I just need to wrap the joists with something in the shop but I have to leave the tops exposed so I can deck over them and not trap anything I use for a UV blocker.
I though about masking tape and brown construction paper but that is too labor intensive and would not stand the rigors of handling etc.
I'm thinking I need some self adhesive something or another but I am unaware of such a product.
Any ideas welcome I am putthing them up this weekend.

WOW, you don't ask for much do you. I don't think you are going to find anything that will fit the bill exactly. One of my first thoughts was tyvek, wraped and taped. My second thought was shrink wrap. I found some sites that had the white or blue shrink wrap which is uv protective. Both though are going to wrap all the way around and you said you don't want that. Is there any reason for not wanting to trap something thin like tyvek?

Do one thing at a time, do it well, then move on.

Not sure what the final finish will be on them, but why not take a little time now and apply some UV protective sanding sealer? You don't have to be real fussy with application, as you are going to scuff it down in prep for your topcoat of whatever.
Just a thought.

As far as shooting it with a sandsing sealer or something, I have yet to find anything that actually offers real UV protection for ERC that does not dramtically take away it's natural color.These joists are going to be shot with a clearcoat to inhibit oxidation which, also works on ERC over time but takes alot longer to effect. I guess my option will be wrapping them. I don't know why I don't want anything between the attic decking and joists I just don't want to have anything there. It's the OCD part of me. I guess I'll have to accept it though as it seems to make the most sense.Thanks for the suggestions sages. :icon_wink:
