I was going to build a small wall today with breeze blocks.
I had everything I needed here, and I downloaded instructions on how to mix the mortar.
3 parts sand
1 part cement
water and a squirt of washing up liquid.
But when I tried to use the mortar, it was like wet sand.
It wouldn't stick to the blocks, and it wouldn't hold them together. Even when it had dried.
In fact, even now when I lift one of the blocks off, I can crumble the remains of the mortar off it quite easily with my thumb.
What did I do wrong?
Too much sand and not enough cement?
I did notice that when I applied the mortar to the block, it seemes to suck all the moisture out of it, leaving me with a crumbly sandy mixture.
Should I have wet the blocks with water before building with them to prevent them from soaking up the water from the mortar?
