On the opposite side, the 75º wall we made a short knuckles section going to a couple hand jams using the same blocking method as the other wall. After all the plywood was in place on the wall I began the long messy process of coating the crack grips with layer after layer of drywall mud and liquid nails. These materials are sandable and you can even produce crimps and footholds. The key is to build up a base, that’s not too thick, with the drywall mud, then coat and seal it all together with the liquid nails. At the bottom of the crack pods I built up thick layers of liquid nails to make some juicy locks. Inside the cracks I made smooth bumps and ridges to make it a bit easier to get locks. Without any kind of texture in the crack it was way too difficult for me. Cardboard strips for smearing the goo and disposable gloves can help keep fingers clean.
