Yea, very careful -used 5:1 sand:cement ratio thru out over wire mesh wrap which is very necessary to prevent cracking in aircrete. Thanks again for replying me a 2nd time. Goodnight for now till next learning opportunity crops up.

Thanks John D V2.0. The external wall is being rendered as I build up (so as to not use scaffolding) to a thickness of 30mm using chicken wire mesh /mortar and last coat SBR bonding of white 0.2mm stone (dash). Also the inside is being rendered with 12mm mortar and will be finally covered with...

Hi everyone, thanks for previous magnificent help. I am about to finish my 3 x 3m rear extension. Only 2 rows of block remaining to go up before the roof is loaded. Being using 2.9N aircrete blocks of 440x215x215mm for my solid wall. [ Can't seem to find 2.9N blocks in the market. They continue...

Thank you so much. I thought of this remedy but was not sure it could be used here. Now, u have settled my mind and I can sleep easy. The work you do here is much appreciated. Many times, I get my answer by viewing previous replies to problems. More grease to ur elbow.

Thank you so very much- that's what I was thinking to do but was afraid that the protruding external wall sections will be point of weakness / cracking and therefore destruction by strong winds. I guess I can shave off (-as its soft aircrete) the extra protruding external wall sections and build...

There is a 90mm concrete/ rebar bond beam between the square courses and this recent unsquare rows.

The 1st row (on top of the concrete bond beam- which is wider than the blocks underneath and such led to our miscalculation of the exact square /plumb line) is out by 8mm. As the 1st row of blocks are not square, although all the blocks on top of them are plumb with regard to this 1st row, the...

hehehe - we DIYers do try still be here waiting for ur input. Enjoy the Big G

Okay, the 1st row of blocks are not square and so while all the blocks on top are plumb and level with regard to the 1st row, the whole wall is not "True".

The building is ongoing. It is the external wall (one solid leaf) that is not square starting from the 1st row of blocks on top of the already installed 1st bond beam. All the blocks on top were plumb and level but out of the original 90 degree angle -square. I am worried that they are not...

I am currently building a 3m X 3m rear extension (-permitted development) with 2 types of Aircrete blocks - 215mm (x 440L x 215H) and 140mm (x 440L x 215H). At one corner where these blocks meet, I just noticed that the 140mm blocks are vertically out of square by about 8mm at the widest point...
