Use
i sprayed 50 bags this week and it hasn't fell off the wall yet ?
With slumps and cracks it only seems to happen when it gets put on too thick in one pass. We have been putting it over uf fiber base and hpx at 10mm and doing it in 2 passes. Spraying it pretty wet ruling the first pass with serrated edge lightly and leaving it a while before we put 2nd pass on.

Makes me laugh all this hatred towards K Rend back in 2008 when we first started talking about coloured render on this forum K Rend was all anyone talked about and few people had issues with it, everyone was whacking it over sand and cement and all-sorts...then it was Weber then it was Parex.
The fact is some people prefer applying one or the other but they all f**king crack.

The cracks often referred to with k1 are surface splits that are forming before the scrape, a slight breeze or direct sunlight causes no end of problems, something you just don't get with other manufacturers.
On top of this you also have problems with the material jamming rotors blocking pipes and even a snapped mixing shaft as a result.
Laugh all you want, but when you have applied 1000's upon 1000's of metres of the competitors material without any major issue and you then use a few pallets of this stuff, and experience all the problems it can bring, there's no wonder as to why no one wants to use it.
10 mm is no problem in one pass with the likes of Parex and Weber Jim.
These products don't separate or slump on the wall at those thicknesses.
It becomes more labour intensive when having to do the two pass system,I do like Krend finish,but just too many issues and the jobs hard enough without a problematical product to contend with.

Lol, those splits are caused by rough ruling off leaving air pockets between the spray lines. That got figured out months ago. We've never had it but I know guys who got it all the time. They don't anymore though.
Always the gears fault tho.... A spread who doesn't know everything? I'm not sure that they exist.
It must be a coincidence then that the ruling and spraying went to s**t on the areas of wall that where exposed to the sun mid afternoon and not shadowed by the scaffold, as it was fine everywhere else.
Why take the chance ? Weve used every manufacturer going over the years, the only issue we've ever had has been with k rend, so we simply won't use it again.most lads I know won't use it, look at the reviews on here, the general consensus is its of poor quality, everyone can't be wrong.
Do you work for k rend?

Not if you think about it. The air pockets left by a quick whip over by your average house basher with a rule get more of a chance to dissipate themselves in slow setting conditions as the gear pulls itself together and sorts itself out.

Nope, been spreading renders for over 30 years now. There was a time there was something to whine about but the gear these days just about puts itself on the wall. No one makes a bad render these days.
Even so, you still get the whinging that some of the gear is slightly different to others. Yes, you need to set your machine up to suit the gear, and yes that is different to different gear. You also have to rule off as you should anyway, so what?
Learn your trade and give the customer what they ask for. Sorry to be frank.
Sorry, are you saying that there's air bubbles underneath the surface, but the ones in the shade disserpated, as in the air bubble floated up and out of the render?

You mean banana split?

Between the spray lines, yes. It's easy to see if you have this problem because all the splits will be horizontal or follow the lines of your spray pattern.
We are talking fractions of a mm here where a quick whip over the top with a rule doesn't push the gear together properly.

Learn the trade ....
I'm not one of these that's just bought a machine and jumped on renders in the last few year.The customer doesn't want a sub standard product for a start, we set our machines up different for every manufacturer there's no issue there, and we apply 10s of thousands of metres every year.
It's not winging if the gears inferior to others, they/you can say it's fit for purpose or what ever,but over the years I've had various issues using k rend, so simply don't bother anymore, shading issues etc. the after service was dreadfull, we were buying big quants and they still didn't want to know.
There are better renders out there with better service, you may be correct in what you say, they may have improved the product but I ain't interested my opinion is based on experience.
I sprayed it myself with neat bands overlapping as I always do, it doesn't just get a quick once over with the rule either. And no the splits did not follow the spray pattern. But thank you for your help in pinpointing exactly where everyone is going wrong, without even knowing how it was applied, weather conditions, substrate key or suction, thicknesses, or the individuals working practices. You should be a rep.

Maybe I should!
We had a gang who got them not often but still got them, and others who never got them. The gang who was getting them hasn't had them for months now we've shown them how to rule off old school. (Nothing special, just slow down a bit and work the gear around a tad more.)
And yes the quicker the drying conditions the more chance of them materializing.
Next time you use the gear if you do, give it a shot. I know its difficult to accept as your clearly do everything perfectly that some find the gear to actually be fine and decent to use.
Look at things this way.
Your Mrs wants the front room painting, she spends hours thumbing through brochures to find the perfect colour, drags you to B&Q to buy samples to test on the wall which costs you about 20 quid, you spend the next 2 weeks looking at said samples on the wall whilst she makes her mind up.
Eventually after wanting to poke her in the eye for her indecisiveness she finally makes the decision to go with Dulux County Cream, the joys. You ain't got time to do it yourself as you are too busy rendering so you ring your mates Dave and Colin master painters from the pub to give you quotes.
Dave turns up, gives you a quote no problem.
Colin, well Colin doesn't like Dulux, he read on a forum someone had a problem once but he'll stick Crown magnolia on, as its nearly there.
Who gets the job?
In this thread, there's not just me saying that they are having no problems....

You win every job you quote then?
Impressive!
What if another guy comes to quote who says he uses the gear they want all the time and its a good choice? You end up getting discredited and dismissed, that's if you get that far and they even ring you as they are only ringing the guys with the right logos on their websites.
In my experience people get at least 3 quotes which they should if they are sensible. You are on the back foot before you start. I can't remember that last time I went to a quote and the punter didn't say they'd been googling for hours.

Thing is most clients don't know what make they want, only the finish. They only know it as k rend or K render from what they hear or see. When you explain all about monocouche renders they then open there ears and take your advice, which is what we are supposed to do anyway in my eyes.
Once we tell them we don't use k rend and explain the benefits of us using Parex or Weber they are more than happy.
The bloke who says he'll use k rend is the bloke who will most probably do it the cheapest and quickest with little effort put into the finished product.
Not saying anyone who uses it is s**t but if you can't give advice and choices and only go with what the client wants without them actually knowing what they want your on to a lose lose straight away.

If they're googling for any amount of time it's safe to say they won't have their heart set on K-rend!!
So the general consensus on here is the gear was/is dross....which is what I said originally, so its pretty much just you thats never had any issues with it.
