![]() ![]() Possibly relevent to the original post, if wet plastering solid walls then a basecoat is needed. I can skim pretty well now but cant cover anyhting like the area a pro would cover in a day so I'm using a local plasterer on my renovation and extension/loft conversion this time around, with me doing the odd bit as needed. I did a plastering course many years ago as had heaps of plastering to do in a renovation and it was our first house (and we couldnt afford a plasterer). ![]() Ofcourse another consideration is that skimming is not really something most folk would try DIY (give it a go, it's fun, but don't wear your best shoes). I suspect that DIY would result in a lot of sanding and it may be very time consuming. Having watched an office fitting crew at work some years ago, I saw that taping and jointing to a high standard was skilled work, they were fast but very attentive to detail and once painted you couldn't so much as see a joint or seam. Skimming is a more durable finish IMO but the aesthetics of skim or taping will depend on availability of skilled trades to perform either. This is just my own speculaton, I have no data to prove it ? But I would think side-by-side, a 12.5mm boarded partition wall with a skim either side would have approx 8mm or more gypsum than the same taped and jointed and would perform better in terms of both sound transmission and fire resistance. Becuase this site applied finish can't be quality controlled by the manufacturer, I'm assuming they dont give performance data (or maybe they dont give data becasue my idea is nonsense ? ). ![]() I've always thought that for a given wall or ceiling board, a skim adds 3.5mm to 5mm of gypsum increasing both sound deadening and I would also think fire performance. ![]()
