Is floating becoming popular again?, is production up for hardwall, tough coat etc. Seems to be more about than I've seen for a few years,imo, I've never been a fan of dabbing,

Good question @pftmonojetman. From what we’ve seen, the market is not increasing at same rate as other areas of construction but this is still very much used for repair work (rather than new builds). It’s good to hear you’re seeing more of it about though!

Is present day bonding just hardwall in a different bag ?
It has a different texture than it had yrs ago

Hi @irish_spread – in short, not quite! Bonding (or BondingCoat) and HardWall are used for different backgrounds: HardWall is for higher suction backgrounds and Bonding is for medium to low suction. Bonding was updated a few years ago though, to make the product a bit finer and easier to trowel. That’s probably why you are noticing a difference.

When will we see a fast setting undercoat. Or an accelerator to add to it.?
Would be ideal on domestics. Time is money after all.

Well @dustydave it’s interesting you say this as we've seen a big increase in demand for this so we've been looking at the different options. I can’t say too much at the moment, but when we have some concept stuff we might well come to the Plasterers Forum members and ask you to try it out for us…

Do you have any new base coats in the pipeline?given the choice a lot of spreads would chose to use s&c over gypsum based backing coats

Hi @kgreigh, it’d be really interesting to know why you would choose sand and cement (s&c) as we hear different reasons from different people! This sort of feedback helps with our product development. In fact, if you don’t mind, could I give you a call about this?

Can we put to bed , that you can use hardwall on solid 9" brickwork outside walls ( not out outside ) hope so cos that's what your tech dept AV been telling me for years , it replaced renovation plaster

Good question @superspread - HardWall can be used in these circumstances as long as there’s no evidence of penetrating or rising damp. If this is the case, it should be treated and then we would recommend DriCoat as it’s best suited for these backgrounds. As for Renovation plaster, this was replaced by Hardwall. Hope that helps!

While we're here, it would be good to get some feedback on the undercoats you like to use...

Which undercoat do you prefer? Where do you use it most ie on renovations, extensions, patching etc?
 
Do you have any future plans to have available a faster setting finish plaster on mainland uk.
Like ultra finish that's available in Ireland.

Would be more than happy to give any new products a try and give feedback.

So to all the doubting Thomas's out there that questioned me on this for years ,your apologies won't be accepted:tarjetaroja::coffe:
 
Sand n cement with water proofer ur back grounds are way to expensive for me as for drying time charge for 2 days still be cheaper than rubbishy hard wall or bonding lol

Why cant you make bonding for high suction? I will buy a bag of bonding before I would even consider hardwall or tough coat because it has all the uses, fair enough it will pull in quicker on normal brick but if you control the suction it's fine. I wouldn't recommend floating a whole room with it cause the others are nice to use. The new bonding isn't as sticky and a bit more like hard wall but ok to use and what's the point of browning these day? Combine all the plasters so you only need one also what's the crack with the new drywall adhesive?

S&c is more forgiving imo I don't dislike hardwall or tough coat I just prefer s&c,hardwall is easyer to use on more even backgrounds ie blockwork than it is on old substrates,I tend to coat up then turn straight back and put a second coat on when the substrate is uneven I find it helps with floating.you are more than welcome to call me il pm you my number.:)

I think hard wall is ideal for old substrates ,ie refurbs,especially if there's any thickness to be done,just my opinion
 
Problem with bonding is it shrinks, only good for patching. Hardwall is good gear though if there is no chance of damp.

I don't dispute that it's a good product I just prefer s&c,hardwall Is convenient for renovations especially if it's just one or part of a wall etc,do you just one coat in these situations for example a wall with varying depths and suctions?as above I do two with the same gear in these circumstances it seems to help the surface dry more evenly fo floating.:)

If the wall is relatively flat I'll pretty much get it out in 1 but if it's a bit gobby ill scratch it ,but I still rule the scratch coat so it's flat and plumb ish ,so when the float coat goes on I've got a nice even 10/12 mm all over ,done a big stair case wall like that as we speak
 
Flater the building out is the easier it is for the top coat , u londoners mustnt be as daft as a thought :bananahappy: lol had to get a dig in
 
Sand and cement always depends on your labourer.......for this reason I always prefer hardwall.

But id rather just skim.
Bg....cant you produce anything like mp its so much easier to use.

2 big firms in the northwest are saying dabbing is getting phased out because of plasterboard waste issues is this true??
