I will be using this next week ! , the last time i used it, i seemed to get a lot of air bubbles some the size of a two pence piece !.
do you guys have any ideas on how i can use this render and not get the bubbles please ?
Thanks for all replies.:whistle:
 
We are whisking in a tub, and hand applying the ocr, .
no serrated straight edge ! i have one in my lock-up though .

Try using Parex microgobetis before the ocr.
 
Ok i will try the serrated straight edge ! so i apply by trowel , the rule with serrated ? then rub-up when firm ? not sure of the way use would do this !!
 
After you have ruled it with the serrated edge try not to over work it with a spat, you may get those bubbles. If time allows I like to leave it til I can get an I section or a spat with an open angle over it then sponge it. It is still quite soft when I do this.
 
Just float it the same way as you would sand cement ? Then sponge it , sponging by its self without the hard float on it .... It will still end up bumpy just good to the eye ....
 
Haven't had that...we spray a thick first pass then put a tight 2nd pass on, never had any probs, get the power float on it floats up lovely :)
