I have had to repair some thermalite blockwork that had masonry joint hangers put in at the wrong height, plus a few cracks. The repair work mortar comes out easily with an old 10mm wood chisel an mallet, it's rubbish. I'll have to hook it all out and replace.
Fresh bag of cement, using 4:1.
Has it dried too quickly? I did give the joints a spray of water before repointing but it all dried out very quickly anyway.
Maybe I should have given the freshly exposed block sides a dose of 5:1 pva mix and let it dry, to seal and prevent the blocks leeching away the moisture too quickly?
