K Rend

Hi folks im new here and just joined to find out if anyone here uses k rend. I have been using it for about a year now and am putting it on by hand, not the best stuff to plaster with but used to it now and getting it flat off the trowel. We are scratching it and nights now because that's when it seems to be ready and it works fine but when u shine a light right across it when it has been scratched it is all humps and bumps but looks nice and flat in day light. Is there anyway u can get it perfectly flat?

use a straight edge and dont move it about with your trowel once straightened, and an i section helps

Oh it's just a Darby? Well thing is its not the plastering
that isn't flat it's when iit's been rubbed with that pad things with all the spikes in them that makes it all lumpy but looks fine in daylight. But when they fit this soffit lights that shine down its going to look crap! Or is that just the way it looks with a light on it in the dark?

Its like anything else, you can only work in the lighting conditions your given and it will show up deviations when lights are beaming down fro a soffit. The I section is a great tool but its hard to combat situations such as these sometimes.

Yes it just takes the smallest discrepancy to look bad aand make a shadow. I just always wonder if other peoples k rend is the same when a bright light shines across it? The weird thing is it looks so smooth aand flat in daylight! Not to great when the sun is low and
shining across it tho

Its nothing like a darby, its used nothing like a darby its used when rubbing up either later on or next day.

all K rend specifications for scraped textured renders outline that after applying the silicone FT (final coat) that you should 'rule to line and level and allow to set' , before scraping. this helps to eliminate the chances of large tolerances in the surface of the render when complete.

you hold it flat on the render and scrape any high spots off go over the whole wall with it first then scrape with nail float

It's not the k rend that's the problem though it's on flat enough it's when is scraped its putting it off the flat.
 

s.p.t plastering

How that? Just rub in small circular motion with nnail float is it not?

If you rub in a circular motion like that with out an i section first on a big wall, your bound to get massive dishes that looks like satellite dishes when sun shines across it..

Same as sand and cement floating, i try to pull the float one way when floating S&c after it's all ruled..

Last night when we were rubbing it we just used a light shining side on so we could gently rub down any bits that had shadow and it worked ok. Also went to look and other peoples krend in the dark with a light right across it and it looks bad to! I would like to try a I section but is far as getting krend finished perfectly flat without any discrepancy I think Is impossible!

hang on. im not asking people how to float a wall up. you are.... and your saying yours looks s**t. your obviously not doing it right or using the right tools. if you knew what you were on about then you would realise that your question is a little bit daft and that it is obvious that no matter how flat you rule your wall, when your having to scrape back, if you use only a float you are going to take more of in some places than others. i think that would class as you being s**t. :)

Lo so funny mate it is possible to get it quite flat but if u show me a renderer that can have a wall look perfectly flat when the sun is shining at that funny angle then I will eat my hat ,just try and get it to a nice flat finish with no misses and no big scrape marks give it a good brush and bobs your uncle
u can shine a halogen light on a pain of glass and see defects if it looks nice in the day time why u worrying,who's going to shine a light on it at night anyway
madness
