Cheers

if its only an out building why not just foam filler it then when set cut away neatly and paint over it

best to cement otherwise it might collapse, they're are cracks here and there as well, ive never mixed cement before so just need some idea on mixing

Your best to remove the water damaged bricks , and replace them , mix your sand and cement >> 4 sand 1 cement , for rendering or brickwork , cheers Alan.

6:1 unless its exposed area

if rendering you should also put some water proofer in with the mix the ratios will be on the tub
you should be able to get some from the diy or local builders merchants
