TRUDI

We have completed a closed panel timber frame self build with MGO internal board. We have huge issues with plaster - cracks on on every joint, bowing to every panel and cracks through coving & cracking tiles. We have been advised that this is because the wrong bonding agent was used but no-one seems to know how to repair this. We have been assured that structurally it is sound - the damage is cosmetic but of course expensive (& not covered by structural warranty or site insurance). Suggestions to repair are easifill (tried & better but hairline cracks have reappeared), acrylic filler or complete re-boarding. Has anyone else had similar issues or can help in anyway?? Any assistance would be gratefully received, as we feel that everyone is shutting up shop and we are going round in circles!!
