CPI and hardwall

[User___removed]

I have a job to start soon.the spec is 2 coats of hardwall/skim.as I am planning to use my ritmo for this one would it be better to use CPI as the scratch then hardwall?could have suction problems spraying 2 coats.
Cheers

Why 2 coats? Whats the thickness?

It's a fire damage job so insurance work.its over rib lath so 2 coats needed on this one.

Thickness 30mm

CPI is waterproof isn't it? Can't see getting 30mm on in 1 day and it will slide the next day I would think. Never used it except for a sample 2m2.

I mean CPI base coat then topped with hardwall

Hardwall be better I think. At the thickness you might get away setting the next day without to much problems with suction. It's lighter gear so be easier to build out the thickness.

Should be 3 coats on wire

I'd stick with hardwall I haven't sprayed it yet but I can imagine it being a bit easier and like gibbo says you might need to 3 coat it so the suction might help

 

[Gibbo]

The pricking up coat will give you suction

 

[spunky]

Not if it's CPI

 

[spunky]

If anything bobby you're going to be dealing with the suction of hardwall regardless and CPI as a base coat could cause you more problems with drying times and slumping and hard walls cheaper

I had no problems with floating on cpi scratch coat as long as your topcoat is about 8 mm

Whatever he wants to use Garry, he might need to two pass the second spray so the suction might help

Had a few problems with CPI at the start but soon got a system sorted.with the high volume of waterproof in the gear it's not a great material to work with.**** using it external in the colder months.
