Ghost prevention

[Ivor]

hi, I'm going to try one pass over tightly dabbed on 10mm beads wich the builder has dabbed on and has done a spot on job to, I usually 2 pass on block never sprayed 1 but was a bit worried about the chance of ghosting so was thinking would a primer like micro or something similar reduce the risk as it would give even suction on the mortar joints ? Just a thought cheers .

10mm render isn't thick enough mate surely?
Parex spec 20mm down here near the coast now.
It being a breathable render I would be cautious.
As for ghosting I would do the beading again getting full thickness.

I do 10mm regulary on 5mm base render. I try to two pass but spraying on 6mm then 6mm is not that easy. I do manage it somehow but always wet on wet.

It should be ok,I have used 10mm beads a couple of times on small block walls that were nice and flat so there weren't to be any risk of low points and there was no ghosting,I'm sure there would have been occasions on bad blockwork where Youve had mono @15mm at the beads and then tighter where the bad blockwork is as you've kept the render flat and had no problems with ghosting.

I always use 10mm beads.although I squeeze them a little so once dabbed out give 15-17mm thickness.i personally wouldn't risk that thickness on block

 

[Ivor]

The beads are dabbed on so won't be 10mm just wondering as I'm Gona go for one pass it would be around 15mm scraped back to 13

What's your thoughts on the the micro reducing the Risk of ghosting ?

Save your money mate.tell the builder,saying that get it in writing the mono doesn't meet the thickness of manufactors spec.
Should be ok at 13mm though.
I know guys who spray in 1 pass with no problems.

I sprayed k rend Thursday in one pas about 15mm thick. Was fine didn't slump or anything

Rowland if you micro then spray one coat it'll prob slump being krend , me and rich did the exact same thing, if beads dubbed on then should be fine in one coat [emoji3] go for it groper

It's parex I'm a horse it on one coat and run. I sprayed over base coat with mono in one cost the other day was supprised how thick you can get it on in one pass .

I'm not a fan of 2 passes. Block work with dabbed 10 mm beads is the norm if im supplying ☺

If it's parex then no probs Rowland [emoji106]

Ivor we always use 10mm crack on mate if it does ghost just blame him anyway he beaded it

Parex would spec 120mm if they could get away with it.

It's in their interest to sell as much as possible.
