And while on the topic when sorting a mix, is a 4:1 ratio based on

volume than the same weight bag of sand.
So a 1:4 mix (per the shovel) would be 1/2 a bag of cement to 3 bags
of sand?

I'm reading (now) that for render a 1:4 mix is too strong anyway.
And then i've done 1 bag of cement to 4 bags of sand which puts me at
1:2.6, is that going to crack up?

Classic - do a job then research it later!

I've tended to count shovels when mixing so volume. Someone with more
experience may be along shortly.
