Hi. I'm redoing the walls in my hall/kitchen doing backing coats myself (fair bit of blown render, so I'm redoing them). I'm not a plasterer, but have been:-
cutting out ~1m2 sections of the existing render
knock off back to bare brick, clean up with twist knot wheel on a grinder
Unibond 3x 3:1 pva:water
Last coat tacky before applying bonding coat, building up to the surrounding thickness and ruling off
Results so far seem good (and flat, way better than I could do if I wasn't ruling it to the surrounding render) and solid but I had some questions?
Existing render is up to around half an inch thick in places. Am I ok without metal lathing at this thickness? No tiling is planned, just painted walls.
I could use hardwall, but I've not much experience with it. My understanding is bonding coat is easier to work with and rule off. I could PVA to control the suction for hardwall to make sure it doesn't pull too quick to get it ruled....but then if I'm going to use a bonding agent why not use thistle bonding to my mind. Like I say, results so far seem fine, but I've lots more to do...seeking opinions please bearing in mind I'm not a professional!!
