1. What is the best way to ensure airtightness at the wall/ceiling joint before skimming? I have cracking here in a few different rooms of my house. Some original lath and plaster ceiling and wet plaster walls, some with an overboarded ceiling.

2. Whats the best way to repair the cracking in the other areas that aren't being reskimmed?

I've seen suggested on here to put mesh tape before plastering but I was wondering about an airtight tape that could be plastered over?

Thanks]]> Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299822#Comment_299822 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299822#Comment_299822 Mon, 23 Jan 2023 14:07:34 +0000 Nick Parsons Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299823#Comment_299823 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299823#Comment_299823 Mon, 23 Jan 2023 16:55:00 +0000 tony
As you can see the cracking I think simply caulking with acrylic sealant/painters caulk would do the trick]]> Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299826#Comment_299826 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299826#Comment_299826 Mon, 23 Jan 2023 17:47:49 +0000 djh Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299840#Comment_299840 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299840#Comment_299840 Tue, 24 Jan 2023 10:18:15 +0000 will t
Posted By: djhDon't forget to leave a little slack at the wall/ceiling junction so the tape or membrane can accomodate any movement without being torn.


Ok, I guess just enough slack otherwise the corner would be weird to plaster over...]]> Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299845#Comment_299845 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=299845#Comment_299845 Tue, 24 Jan 2023 11:38:40 +0000 djh Posted By: will tOk, I guess just enough slack otherwise the corner would be weird to plaster over...Yes, you need slightly more of plaster covering over the tape than a normal skim.]]> Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300266#Comment_300266 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300266#Comment_300266 Mon, 13 Feb 2023 10:46:22 +0000 cc64 Plaster skimmed nicely.]]> Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300267#Comment_300267 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300267#Comment_300267 Mon, 13 Feb 2023 10:58:22 +0000 lngn2 Ensuring airtightness at wall/ceiling joint http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300304#Comment_300304 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17710&Focus=300304#Comment_300304 Wed, 15 Feb 2023 15:16:25 +0000 cc64
