June 30, 20197 yr Looks like aircrete can be a bit of a headache where large is concerned. With his is mind whats the best lightweight block 3.6n option to receive either parge coat or wet plaster finish?
June 30, 20197 yr Concrete block Thermal are no good for Parge Sound coat helps between party walls Speaking as someone who uses a lot of it I would prefer that the BW Is properly pointed I would have cost me nothing to Parge our build but I didn’t bother The house is fully airtight without it
June 30, 20197 yr Author What score did you get then @nod I thought conc weren't any less air permeable than thermals
June 30, 20197 yr My air test was three Nothing getting out around walls The tester remarked how airtight the building is Unfortunately planning dictated Over 30 sash windows that are not airtight Regarding Parge I use tons of the stuff each year mostly for sound blocking The bricklayers no this is being done so don’t bother pointing and bar jointing If you have to SC on thermal blocks you will need to seal them As the SC will dry to fast and leave a powdery finish to D&D onto

I absolutely drenched mine with the hose before the scratch coat was applied and 5 years in I have very little cracking.
June 30, 20197 yr We have in the past But with most site water coming in a cube and the nearest tap may be half a mile away We are stuck with SPR But as I say most are concrete blocks on apartments or duplex As I say pointing is much more effective Or wet plaster
