epsilonGreedy Posted November 25, 2020 Share Posted November 25, 2020 This stuff was offered to me when I enquired about 2-pot epoxy glue. Back down in the Solent getting hold of a non trivial quantity of epoxy glue was easy but in Lincolnshire they looked confused at my local builders merchant and suggested I might find something in the selection of toothpaste tube sized exotic glues. I have a vague recollection Cascamite was used in boat building before 2-pot glues became standard. The job for this glue is to firmly bed down a cross brace of thick plywood across the corners of my wall plate. The plywood will be screwed into the 100mm wide wall plate and the epoxy/Cascamite idea is to just beef up the job. Once the corner piece is bedded down I will "dragon" tie between the hip rafter end and the cross brace to prevent any tendency of the hip rafter to slip outwards at the wall plate.

epsilonGreedy Posted November 25, 2020 Author Share Posted November 25, 2020 Not that effective in a gap filling or exterior role apparently according to this mega wood glue test. The data is in this Google spreadsheet though quite a few of the products sound unfamiliar so probably difficult to source this side of the Atlantic. https://docs.google.com/spreadsheets/d/1GAZrhrtJPi8-iqPRVfqgOgf7RTg8Vqmen6OKJ4Ae6_I/edit#gid=84891670 If interested check out the "Overall" spreadsheet tab.

I would use D4 glue and nails My concern about D4 is that it will bubble up and will result is the set brace being misaligned. I have only used D4 before doing floors. I do have many bottles of D4 left over! Link to comment Share on other sites More sharing options...

If you don’t moisten the surface the bubbling will be diminished/act more slowly. ? edit, with mine I used 4x2 and paslode nails.

PeterW Posted November 25, 2020 Share Posted November 25, 2020 Another vote for D4 glue and a couple of screws to hold in place and then whack 4 or so nice big ring shank nails each side. Think I went though about 1500 paslode ring shanks on the last roof I did - it’s not going anywhere ..!! 1 Link to comment Share on other sites More sharing options...
Temp Posted November 25, 2020 Share Posted November 25, 2020 The tie itself will probably have a 12(?) nails each end at most so no need for more than that between ply and wall plate. I'd use D4 or Titebond perhaps. Link to comment Share on other sites More sharing options...

It won’t have chance to bubble up squirt it all on, slap on timber, fire 34- 45 65mm ringshanks into it, it will still be there when you long gone.
