Weber Monocouche - should it REALLY look like this?

[Mouldyoldspudgun]

Has anyone else noticed the increase in people doing Monocouche as a two coat system?
Obviously a contradiction in terms.

Yes, when I first did it on a office block in Northfleet in the very late nineties it was one coat and the rep gave us two wooden handled
spatulas with metal blades a couple of scorers and then f**k*d off. How times have changed

I think I must have dyslexic fingers that was meant to be the late eighties and scourers, not nineties and scorers

When i first did it no f**k*r ruled it

That’s what he left the spatulas for, Ive still got it, did you ever try ruling it we used Derby’s but by f**k did it tear instead of close it in

 

[Gibbo]

Yeah we ruled it had no problems just a bit at a time

Can also happen if the suns directly on it for too long???
I spray on site most days and the block works so bad in places it must be 10mm max in others prob about 25mm and as long as it drys naturally you’re normally ok!! know one ever says anything to the brickies though lol
Webber do a colour match pair so worse case that’ll cover it up.

why don't you stick a conta charge in if you have extra work and extra materials ?

Derbys are good for absolutely nothing!

Derbys are good for absolutely nothing!

They are pretty damn good at closing stuff in plus the handles come in handy for hawks

Yea we are but dealing with site agents is a whole different problem lol

I've worked for persimmon who spec a one coat on to 3.5n blocks. 50% of the time ghosting would appear.

On my own jobs I always use rendaid and mesh. And anyone who says they can't use a derby as a straight edge...errrm

In my honest opinion a base coat will prevent this happening as the suction is already killed by the rendaid. Leaving a nice uniform substrate to apply top coat.

And yes bricks are better/stronger and longer lasting. Rendering on to blocks is a cheap and quick method used and should not be a first choice if longevity is required.

WEBER make paint which match the colour of the render I believe this could be an option. Failing that just use a good external paint.

Celcon blocks are dreadfull to render over, cheap nasty,they suck like a hooker at Christmas.always use a primer or a base coat before mono.
