So my brother and I put down the compound, used all 8 bags, it wasn't enough, I had to go out and buy an additional 5, used the spiked roller, tried to use the trowel as little as possible. so I have covered 70% of the surface i'd say, it was definitely difficult trying to keep it level, I found the sticky adhesive came off a bit whilst rolling, and by using the spiked roller, quite a few threads of the mat came off, but I don't believe any wires came lose or moved too much. unfortunately the cold tail lead is sticking up a bit, and also the powerleads are still above the service here and there, i'm planning to do the rest of slc tomorrow, a couple of areas I can see that the electric wires aren't so covered as others, but i'll just have to do what I can tomorrow. i'm feeling average about things, I don't think it was a complete disaster but it definitely wasn't as perfect as i'd hoped.
