Hi there, new poster, ex-plasterer, moved into fire stuff, cos, well, dermatitis, knackered knees, all that jazz!
Anyway, here's my experience with *cough* "Make Good" multi-skim... First off, yes, I think it's shite, might as well get that out of the way... Read the instructions on the bag, seemed simple enough, 1 coat, 2 coat, trowel, once it changes colour, final trowel, though I did note the "DO NOT APPLY FINAL TROWEL UNTIL IT CHANGES COLOUR" warning...
And yeah, well, I've been doing work on a new house, was in the box room, reskim, I had enough thistle pink gear left over from previous work, which I chucked on the ceiling, absolutely grand, trowelled in as expected, consistent throughout, never batted an eyelid, came out lovely... Then, I had to break into *cough* "Make Good"... Downhill from there...
Stuff is gluey and tacky, whatever you do, do not put on walls that are still have wet patches of PVA, no matter how much in a rush you are. Secondly, the setting time was immense for me, I put one wall on, 3.5hours later it was starting to change colour, attempted a bit of a trowel because there was still trowel marks because it seemed, even with a trowel lubed with a bit water, it sorta reactivates itself... So left it to fully change colour as in the instructions... And yeah, the t**t goes solid, I literally had to grind the arse off it to get it flat, well, thinking it was flat... After I did it, I thought "You know, it shouldnt be that hard, but that looks okay"... So, I carried on with the other existing walls (2 more), but decided to just tape the last wall that I had dabbed out... Usually with thistle gear on a room, I chuck adjacent sides on in one mix... I darent here, and yes, because I put each wall on one at a time, 12 hours in total it took with *cough* "make good", I would of been finished in 4-5 with thistle... Major difference there.
Hours later, All finished, all grinded down, I looked and thought "I may of got away with that", as, it didnt look too bad, dries to a matt finish... So, knackered, showered and then bed.
Next day, I had a look in, and just wondered to myself, "I wonder what it looks like under a torch"... I wished I didnt look, honest to god, it was rough mind, sun hitting that on a nice afternoon would of made a mudhut look the bee's knees, it was awful (Ceiling was still lovely mind)... I was gutted because I couldnt leave it, so, got a bucket of tapers cream and creamed and sanded the bloody lot... Retorched... Spot on!
I literally dont know what I could of done differently to get a decent finish on it, to my thistle standard anyway, it had me lost, and grafting like a good'un when it changed colour.
I'm just pleased I never did this in someones house, cos it'll made you look a right tit, in all honestly, I wouldnt be able to charge someone if under a torch it was leaving it that bad.
I was in B&Q the other day and noticed they had to pallets full sitting there, not surprising, I was speaking to one of their staff about it, and he said there was loads of complaints about it, and I was like "I'm not surprised, look at my hand" showing him my blisters, and then explaining even after that, I had to recoat it with other stuff.
Anyway, there's my experience with it, utter rubbish, never again... EVER!!!
