Hi Ive been a general builder for some time and can turn my hand to most things. Internal plastering no problem, but getting a good smooth finish on render is still a problem can anyone offer any advice.

can you post a picture of a wall you've rendered as it could be how you're floating up or even how you rule off.
try and get a picture from a side angle were the light is casting shadows across the wall so it high lights what you want to correct. |

Thanks for reply, ill try and get a photo. I think for what im doing wrong is after ruling off & getting a flat surface, im trying to finish of with a steel float which is making dents. I read some where that i should be doing circular motion with a wood or plastic float & rub up an even surface. Im going to have a go on a small piece of wall in a few weeks & try it. If you have any advise on how long I should leave it before rubbing up or any other tips please let me know thanks  |

yes you need a plastic float, 6 x 14 inch approx, a new float needs breaking in, chamfer the corners first on some smooth concrete
like a block, you need to take that square edge off all four edge's, then its best to break the face in on floating floor screed,
they have a checked patten on the face that really needs to be worked off before they are at there best for floating render,
when you have one worn in don't use it for concrete only for render or screed.
yes you work it in a circular motion but not just one size circle, variate the size's and over lap all round,
you hold your float like a saw with your first finger pointing a long the handle, reason, when you are experienced with the float
the pressure or lack of it on the finger will tell you if you're hit a bump or crossed over a hollow.
when to float well that comes with experience but you should touch the wall and if its firm but you can leave indents try it with the float
if it gets to dry the surface will dust, if its to wet the float will stick ( only remove by sliding upwards, down will pull the render off )
test walls all over as they tend to dry patchy, if you get a dusting spot flick water on it and refloat to seal it, it don't look good
on a out side render job but its better to seal it and when painted it won't show.
learn your floating on walls you are going to skim. |

Thank you very much for that great piece of advice, Izalarfin I think the penny has now dropped, will have a go soon & let you know how Ive got on. 
The render that ive already done is painted (the stuff that I did before I asked the question), do you or any one else know what to do with the work ive done so far? its fairly smooth, but as it was not rubbed up (metal trowl finish) its a little uneven which shows up more in direct sun light. Of course chopping it off is one option, do you have any other ideas but keep it simple like me.
Thanks again |

only look at it on a moonless night  
is this wall worth trying to put right ? how big is it ? is it brick or concrete block ?.
shame its painted, makes more work as you'd have to scuff most of this off and scar ( key ) it,
probably best done with a needle gun and by the time you've done this you might as well of chopped it off.
you could ex-met it and recoat it, two coat work, scratch and top coat.
someone might say use a water proof p.v.a, but your are counting on the paint to keep it there, ( not my choice ).
by the way you'll never beat the sunlight it will show any marks at some point of the day.
ah, back to the floating, fill any holes with render off your hawk with your float and fill by pushing upwards. |
