Sand cement

Good afternoon chaps I’ve just sand cemented a couple walls which had issues with damp , the customer put KA tanking slurry on a while ago , I scratch coated it yesterday & put top coat on today & rubbed it up . My question is what finish coat to put on it . A friend I know who’s an old school plastered very good to be fare said to me British gypsum guide lines recommend to leave it 28 days before applying finish coat . My mate prefers Thistle board finish over multi as it tends to shale if it doesn’t dry out completely . I was going back Monday to skim it . Any advice I’d be grateful. Thx in advance.

Only need to wait till the floating coats not green (damp) so that it’s contracted and shrunk, going on it while it’s shrinking will pull the skim with it and cause cracks everyone associates with solid walls, but it’s just not done properly often. Board finish is nicer imo, just need to control the suction to your need before skimming or you’ll have a hell of a time
 
People have there own opinion or different methods of doing the job , it’s the easiest job to criticise someone’s work , I certainly don’t claim to be the best plasterer in the world far from it . But now & again if I’m not too sure on something I’d like to think I’ve come to the right forum for advice. ....

I always criticise my own work...keeps me occupied for about 5 seconds :inocente:
 
Haven’t done any float and set in years and that’s more key than I’ve ever given it with no problems ever, give it four or five days in a warm house it will b good to go I reckon

No I went all modern and use 25mm drywall screws barely through the float. Not that I ever get to float with s&c anymore unfortunately.

That’s how my devil float is set up. Recalibrate occasionally with some feeler gauges and engineers blue!

I'm with you, I've seen c**ts devil floating with dirty ass clout nails, you need one of these to get all the snotters off before skimming.

Just come back on here for a rest, my tape has gone viral on another site, literally having to ration samples to first thousand.
 
Quick glance over in the evening over everything you’ve floated that day with a big trowel flattens any small bits.
