Built using too much plasticiser

[Eamman]

Eamman,
It will be perfect.
And for you, who I presume is hand mixing, and not using a machine, it will better as pre-mixing with water will ensure it mixes 100% in with the cement.

That's what got me with when they said mix to the dry mix, it sounded daft! Are you a builder,I'll ask this question anyway, this is for a small dwarf wall greenhouse, and it won't be an even full brick course ,so there'll be gaps,I was thinking of filling 2 gaps wit 2 inches of brick instead of a single 4inch brick just so a brick will go over it better ,if you see what I mean?

Not daft as builder might be using a hose to provide the water, and so cannot pre-add plasticiser to water.
So into big cement mixer he adds 1 bag of cement and (say) 3 bags of sand, and then 85ml of your plasticiser.
And only then adds water using hose.

Put bricks on dry (no mortar) for first two courses and see if it works and if it looks okay.

Already have them out dry, but there will be gaps to fill, and I think I'd be better with as I say 2 inch pieces of brick instead of 1 4 inch!

Actually looks like one gap about 2 inches, which is even better!

I'm more intrigued as to where the 2" and 4" bricks are coming from.

I will cut 2 inches off a full brick and fill gap with it!

Forgot to ask you can one bed up the brick by much, part of foundation is off level by 8mm?

here's one for you,I laid a line on the longer length of the build it's touching the bricks on one end actually first 23 bricks and touching the end brick but, is away from the other bricks in that line! However, I borrowed a folding 4 foot square and all the bricks are to the edge of the square! So, which is right and which is wrong?

put brick out on dry run and there's one gap on the first course,and just for good measure I ran a dry run on course onto of that, and that's giving me 2 gaps! would I be wrong to assume next course will revert back to one gap? sorry for all the questions!
