Heres the backgrounds I've used it on.
Artex (silk) - Hung a good bit could of laid twice as much on had I known Id be waiting. Trowelled up real nice.
New Render after Dpc Installation - Hung for ages as expected anyway and it was laid on a good week after after render was applied.
Old skimmed walls with some bits of paint, walls had wallpaper on prior to skimming - Sucked in quick! set finished in about a hour and a half. Didnt crack or craze (no phone calls yet from client!)
I was using my plastic refina trowel on all but the dpc one and that got a much better finish than my marshall town. I found that when you dry trowel it can skag a bit but didnt with my plastic which is why i used it.
My lab used it over some hardwall he put around skirting lines a good 3 days before and that sucked right in and crazed a bit. Sorted it out in the end.
Its not the best for blending into existing finishes (dpc job). It would flake off as if using multi with no PVA where I tried to blend to original wall.
Overall its quite a good product for certain finishes but not all I would say.
It saves time having to wait for the PVA to set or having to use Plasprime on painted finishes but it sucks in a little to quick on the dryer/older backgrounds.
It also not only saves you money on PVA minimal I know but it does also save labour time (average bedroom about 30mins PVA time?) I pay Â£8.25 plus VAT at the minute so for say a 5 bag room thats a extra Â£20-Â£25 quid in Materials minus your PVA, the mess it makes and the labour I would say its worth it just about!
Im guessing the cost is so high to start because of all the angry phone calls they will get from spreads saying its gone wrong and not working as it says etc etc. But its like any new product that comes out people will be wary and comparing it what they usually use and ready to bash it if it doesnt go to plan. You still get jobs with multi that you PVA well and then still sucks like sh1t but you just get on with it dont you!
Im also wondering what the crack is with Bond-it now they brought this out. Im sure there will still be a lot of use for it but Im guessing they make a good mark up on that than they do over multi but bringing out uni finish will surely affect sales of Bond-it??????????
Just a thought.
