What tape will work to seal seams in tarpaper when use it’s used as an air infiltration and bulk water drainage plane.
Typically I use 3M or ‘Tyvec’ tape when using plastic type housewraps to seal window flanges and joints but I don’t find it adhears to tarpaper consistantly. And when it does stick I wonder how long it will stick for after the siding covers the evidence.
Thanks for the help.

Look in one of the last six to twelve issues of FHB. There is an article on sealing windows with some sort of sticky tar paper tape. It comes in various widths. I bought some, but haven't used it yet. I think you will find that it sticks to paper just fine.
By the way, I have lurked here for a while and I really don't think that these guys have a clue on how to properly wrap a house. They mostly have wags. Now, if you were to do it my way ........

*Thanks Dennis,What is your way of installing housewrap / paper??? You can see my way in FHB#107 See how it stacks up to your method. Do you use a brand name wrap or #15 or #30 felt...???Mike
*Thanks Fred,I don't intend the paper to be a pressure / air barrier. I use string poly /w Lessco boxes and dense pack cellulose.....I intend the paper as a drainage plane primarily and though I lap 5"+ I figured I'd tape (habit). My real concern is the window flange seal. I know - the water will get in anyway and yes I use a drainage 'pan' under the window to direct tha water back out. But I want to stop as much water as possible from getting behind the window flanges.Make sense??Mike
*Mike love to use tar paper but we don't tape. Have always lapped the paper at 6". Tyvec is just to damm much trouble for what you get out of it. Most of the siding that goes on over this is vinyl siding.( yes that nasty word ) The rest being ceder or composision material (Hardie board..Ect..) Have always liked the stuff and find it hard to beat. We have even used it for other things beside what it is sold for
*Mike, I have used Tyvek and I have used felt. On my current project I am going to use generic 30# felt under proPlank siding - hopefully with the shingled effect if it comes out soon enough. I honestly don't claim to know anymore than this. I am using felt because the house had that before. I think I picked up the tape trick from your article, but, many of my FHB are in Wisconsin where my current project is. I am whimisical. The one tennant in my duplex, I am just completing the other half, willl be 101 this June. She has lived in the house since 1965 - and incidentally had a government pension since then. Our tax dollars at work. As the years pass, I find I am less interested in the exact structure of the house, and more interested in how life goes on in it. But, I sure do get a kick out of working on them.Dennis
*Mike, I think Bill has a point. Too many times you can start a project with the idea that everyting will be perfect and it will go on the job site just as you planned it the night before. Well, many times, half way through, all you want to to is the get job done and perfection can come another day. I like Bill's idea of paper because it is easy to handle, readily available, easily transportable, and has worked for many years. Not all the houses that were tar papered dry rotted, or fell down, so if it has worked, with a little luck it will work. Six inches sounds find to me for an overlap. I think that Bill has done far more of this that I ever will. Dennis
*Dennis I have a advanage over most builders in that I get to work on things that my grandfather and uncles build. What I like about this is it allows someone to look at things that have stood the test of time and things that haven't. Remember the big thing about using plastic on both sides of stud walls in the early 70's? How many of those have you replaced now? When I look at something build five years ago that is failing it bothers me. How many people have read the installation instructions for house wraps? How many follow these? what will be the outcome of this ten years from now? Twenty years from now I want someone who comes behind me to say this guy did a nice job on this. Can we do this in todays market? Most of the time the answer is no we can't. Pricing is driving most of the builders out of the market or forcing them to cut cornors to stay in the bid wars. We all have to still make a living but I still want to be able to face myself in the mirror
