EPDM gaskets instead of ZIP System?

I was wondering if anyone has tried using EPDM gaskets for air sealing exterior OSB instead of taping the seams? EPDM is cheap, easy, can be put up in the rain, super durable, etc. I am going to lunch or I would explain more of my strategy...

Flash and batt closed cell with initial flash of open cell

Ok. I'm building an addition. This is in Cape Ann MA. North of Boston. North facing roof 4 pitch that ends in a sidewall. It is a hot roof. it was flashed with 3" of closed cell foam this past october. The foam failed and is now being removed. It pulled away from the roof sheathing and at the rafter tails. Not everywhere, but there Is no Pattern to where it shrank. Some places it shrank 1/8" others 3/4". The installers want to now flash the rafter tails with open cell because they think the sheathing is cold and the open cell will adhere.

Finding the cold and hot spots in the envelope with an infrared thermometer

I asked a few weeks back for advice on an affordable infrared detector for finding cold spots to pinpoint infiltration problems, heat loss and insulation effects. I found a mid-range infrared thermometer: "IRT207 Heat Seeker." You can pick it up for under $30 at Amazon. I have had mine for two weeks and it is getting a workout as I caulk and seal prior to insulating.

Rigid board insulation for an unvented cathedral ceiling: fill the void?

Hi there, first post.

I'm building a tiny cabin, Pacific NW, right on the boarder between zone 4/5, 40miles
east of Portland.

I have vaulted ceiling/gable roof. No interior walls in yet.

I have enough rigid board insulation to fill the void (iso). The sheathing was sealed to the rafters with adhesive sealant when laid down. Blocking at the soffets was sealed with silicone. There is rolled mineral roofing over that, all edges sealed with lap cement. All this was done with the anticipation of filling the void with pink fiberglass rolled insulation, with drying to the interior.

Joint compound over poured concrete wall

I would like to plaster then texture over old uneven concrete. I saw a product called plaster-weld. Can I use the plaster weld over the poured concrete wall and then just layer on coats of joint compound to get a textured even finish, then seal with a primer and finally paint it? When they formed up the basement walls years and years ago, they weren't concerned with even finish. I can send you a photo if you need one. We get very little moisture in basement. Thank you in advance.
