Joe,
some sort of industrial cement glue, i think its a 2-part epoxy, cant remember the name of it though...secadur???? something like that, i'll try and find out if no one bets me too it
.
. It was what was used at Burley, well certaily the holds I know off at least. Not sure about "bondo" though.
make sure the wall is clean and dry, mix glu stick hold on, use gaffa tape (or similar strong tape) to hold hold to wall until glu cured, 24-48hrs, see glue instructions.
will be a scary job testing out the holds above some greasy slab.
best o'luck
Shouldnt it be a 80 deg slab....? technique for a 100 deg slab..same as the Gallery..(:-o |
