Newbie Question (go gentle…)
Had my second go at hardwall plastering a section of thermalite wall in my bathroom.
I applied 1 coat of GyPrime the night before, without watering it down (first mistake?). Next day I dabbed on 4 pieces of 9mm plasterboard and set some screed blocks on the wall the width of my featheredge. Once they were set, I knocked up some hardwall and attempted to get it on the wall as fast as possible (about 3m^2 wall). I didn’t water down the wall at any point that day…is this another mistake? By the time I got the plaster on the wall and tried to run the featheredge over it, it started peeling it off the wall. I decided to trowel it to what I thought was flat but then noticed it started to slump, so left it alone to pull in before devil floating it flat, and ready for another thin layer of hardwall in a few days.
2 days later, I soaked it in a watered down PVA in the morning (and knocked on it to make sure it had bonded to the blockwork), and gave in one more thin coat of hardwall to even out any low spots, then scratched and skimmed it that day.
I’m pretty happy with the end result, although there were a few air bubbles in the multi finish (is this because I scratched it?). I was amazed by how quickly the multi finish began to pull in…it was basically ready for its first flattening just after I finished putting it on. Is this normal or did I do something wrong?
I’ve got a few big walls to do next and I could really do with understanding what I did wrongly; should I be applying more coats of gyPrime, watering it down, or using SBR /PVA to give myself more time to get the Hardwall on and successfully featheredge it? Also, is it a big ‘no no’ if I don’t skim it on the same day thinking – I generally work evenings and weekends (it’s on my own house).
Any advice / pointers would really be appreciated!
