grey was smooth to use , just came from a different quarry (I believe ) shame its not around anymore , always looked better when setting I hate to see part set walls just looks crap,all pink is good all set same colour = job done
 
Same difference with bonding and hardwall both of these can be grey or pink is it because of different contaminants in the ground at the quarry?
 
sounds plausible to me , isn't finish just ground down a bit more than backing coats then retarder other additives added ?
Never really thought about it before , ohh well its something to think about while im throwing stuff around tmo:RpS_lol:
 
Every now and then I get a finish that when dry is nice and flat, smooth but patchy.
seems to have appeared in the last couple of years with a cloudy look. I never use dirty water and mix my second coat after cleaning out the bucket from first mix.
 
About 14/15 year ago I was using board finish and there was a mix up with additives , person was on sick at bg and stuff stayed soft for one and half hours then set solid instantly, I put loads on thinking I could get round it ....nope I wasn't quick enough lol .... to be fair bg paid up and gave us another batch of finish
 
just to mention I think ive been getting them when cleaning down angles then pulling excess water in to early on 2nd trowel. Sorted angles out today as normal with brush but purposely didn't go straight on wall with trowel seemed to help a bit today.

Or it could be that trowel had its 6monthley clean at the weekend lol
 
maybe because thats how we were taught ?? certainly I was taught to use water at college and by the plasterers at work..
 
You have to adapt your techniques to suit the material cassie, you certainly weren't taught to plaster with multi at college. 30 odd years ago. Multi needs hardly any water at all to finish. If you start lashing water at it, your just making a rod for your own back imho.
 
Multi;s pretty much same as board finish mate, I get a good finish on either, and were not lashing water on it..lol.. but a little splash helps, as for adapting, plastering hasnt changed that much in the last 30 years I think... Im not putting the water on with a hose pipe...lol... just the way i was taught, and it works well....

I was taught to use water on the trowel and not to splash it on the wall... and if you do need to splash make sure you use clean water and preferably spray :)

No way is wrong as it all paints the same :)

whats the downside to using too much water on multi @scottie5 ?

I always thought tiger stripes were caused from not cleaning your trowel and the build up creates the ridges....

nope when I was a apprentice many moons ago I would have had nothing but stripes ,lazy ass boy I was,its material or should I say ingredients in finish both board and multi and trowelling too early and patchwork plastering. I.e painted and unpainted areas on same wall , pva thicker in areas all contribute to stripes , main one is getting on it too early:RpS_cool:
 
never had a greasy problem on boards s/c or hardwall ect only over pva'ed low suction backgrounds and that aint very often
 
after 30 yrs throwing stuff around , its only been last decade if not less that I've heard of stripes , this is one reason I believe its additives in material ,more than plasterers error
 
Never seen a streaks or tiger stripes skimming render only on board, and there a endangered species cause I dont use water.
 
each to their own I reckon.. i dont get stripes and use water.. best to stick to the way that works for you..but i have never seen any plasterer not using a flick of water on finish.. ever..
 
can someone put a picture of tiger stripes ? Ive never heard of them, or maybe know them as a different name.. ie. most on here talk about a ''set'' up here we call a set.. a gauge..
