cracks in external plaster

whupdedo

Hi all
I have a job to do but I am stuck looking for options,
It's a new house, built with the insulated walls,ie the insulation on inside and out,with the centre piece filled with concrete,

and on the external the plasterer, instead of using the spray on plaster or the acrylic, used rib lath and sand and cement

Needless to say the whole exterior is cracked all over due to the expanding metal expanding and contracting

My question is, is their any other options to fixing this, other than taking off the plaster and expanding metal, has anyone come across any material that will cover up the whole wall making it look like new and covering all visible cracks thanks

I'm presuming you mean insulated concrete form(Icf)

I believe you would be better off hacking the whole lot off if possible,but could be tricky especially if the metal is fixed through the insulation.
To try and coat over could still leave you with the original problem.

A polymer modified base coat with fibreglass mesh cloth bedded in should have been used,with either an acrylic or polymer modified powder render to finish.

the house is only new,can you contact the builder or the plasterers.
This is a shocking case of bad and inexperienced tradespeople.

Ya its the I c f system

It was a self build and the plasterer was only doing as he was told, the house owner doesn't allocate any blame to the plasterer and was the one giving instructions to him, they both should have known better in fairness, but I have the job of trying to repair it, I think along with you, that the only job would be to go back to the insulation and start afresh

Yes I think it would be best,but as I said just be careful as more than likely the hi-rib has been secured through the insulation into the concrete and taking it off could damage the insulation,creating more problems

Try and find a plasterer who is experienced with EWI

I think the owner will probably just settle for the way it is,as doing the whole house would be financially prohibitive
