top coat s+c

[kirk johnstone]

i went to look at a job today that another plasterer has done, its a render finished with a brush pattern.
the other spread has done a shite job and the fella wants me to go over the top but he dont want to pay to knock it all off, just wants me to go over the top. the problem is i dont think that the last guy has used waterproofer so how bo i kill the suction?

i would normal use pva but alot of people disagree so i want to know what to use?

in advance-cheers lads

Rend-aid

sbr or rend aid. wich one is best, how much dose it cost, were from, how do they work? thanx

 

[irish_spread]

stella is best. BOUT £3 A PINT

 

[beddy]

ive only ever used sbr n its the mutts nutts, dont get any on your hands though

 

[S a plastering]

they are both polymer based i would rendaid it

 

[carlos]

Would you use the sbr neat out the tube or mixed 50/50 with water and cement as a slurry?

 

[ziggy2]

Use as a slurry, as Steve said don't get it on your hands. Costs bout £20 a 5ltr bottle, dogs gonads!

 

[spunky]

use it as a slurry carlos, if youve already got a key kirk you might just get away with water so it kills most of the suction and scratch it again with waterproofer, doubt you want to use youre 3-1 mix though mate chances are the last lad has used 4/5-1 so you could start with a 6-1 with waterproofer and a 6-1-1 to top it ......not sure of the scratch coat though dont know if it would be a bit weak with no lime

 

[beddy]

he wont listen spunky, he loves his 3:1!!

 

[carlos]

Right Have I got the sbr to water mix right ?

 

[kirk johnstone]

aint got enough room for a scratch lads because i will come out infront ov the sandstone heads and sills i have to try and go straight over it, it has not been painted and the pattern he has done has left a good key, i just need to kill suction, i am doing it off a tower, me and my lad and i cant be doing with constantly wetting the wall, just want to know what i can paint on that will stop the suction (but not pva)

 

[beddy]

attach the hose to the tower so its constantly chucking water at it. ;D

 

[kirk johnstone]

dose sbr kill suction?

 

[richardbrown]

yep

 

[kirk johnstone]

i have never used this before rich can you explain how to use it and how much it costs please mate

 

[richardbrown]

if you have the mechanical key there I would just roller neat sbr onto the wall and lay my top coat straight on, if you have any sbr left then divide it up and throw it in the mix for good measure.

costs ....... £15- 20 per 5ltrs, use it neat it will prob cover 40m2 quite easy.

 

[ironmonkey]

mix sbr with cement 2:1 ratio into the consistency of yogurt

do i let it dry first mate?

 

[murplastering]

never used neat sbr so cant coment on that usually cement sbr slurry and let it go tacky then render

Yep,thats how i do it,just dont let it dry

 

[james]

let it dry for 24hrs follow instructions on back of tub , stipple the stuff

 

[ziggy2]

If it's really tight to get more render on why not use Highbuild or Tyrolean the bugger.

if the brush marks are not to heavy give it a coat of primer then a thin coat acrlyic top coat nice finish and wont need painting... these products are made for this... go for a 1.5 - 2mm grit if brush marks are heavy
