Hello im having trouble quoting for a render job im need to know how to work out materials if i was mixing at a ratio of 4:1! thanks
 
1.2 bags of cement
3.72 bags of sand
Thats for 10mm thick

1 cement and 6 sand should do you. About 30 quid for materials if you steal some fairy off the wife.

Arti how is that 4:1?

And Bob why 4:1 inside? That's very strong.

Dug out some stuff from college and the proportion of volume table( yes , very technical) gives you the proportions for 100m2 and the 4:1 section gives the quantities of 0.93 cubic meters of sand or 37.2 bags and the cement quantity of 12 bags for 10mm thick render then i just worked out for 10m2.........i get the feeling you think what i wrote is incorrect??

I very rarely use sand out of bags but I'd say that the volume of a bag of cement is greater than that of a bag of sand. Most guys I've spoken to on site regarding ratios regard a bag of cement as equal to three shovelfuls.
I've used that ratio as the basis for rendering, both internal and external and screeding.
 
the method that i was taught to work out materials was 2 ton of sand will cover 78m square at 10 mm thick with no waste. so what is needed is a quarter of a ton of sand [four barrows] and 3 cement would cover the job

i would have thought that a shovel full would vary more than a bag of something or a bucket full. i can only go off what the information sheet says, whether that same sheet of information is used in the majority of training establishments i cant say

You would think so but they rarely differ greatly in reality. And that's from one labourer to another. On site you just don't have time for gauge boxes or buckets, you've just got a twenty ton load of sand and a couple of pallets of dust to use as quickly as possible.
For a 4:1 mix I'd use twelve shovelfuls of sand to a bag of dust.
Not saying you're wrong Arti just saying how I and most I've seen on site work.

1 bag of cement = 1.5 buckets

1 bag of sand = 1.75 buckets

You want about 6:1 rendering inside

1.5 x 6 = 9 / 1.75 = ~ 5.3

So in summary to make a 6:1 mix you need five and a bit bags of sand to one cement.

Don't forget the frock when you're lashing it on.

Andy I work externals pretty much all the time now and I do it the exact same as you. We get a 20tonne delivery every month or so but we use 14shovels to a bag of cement in the first coat. To keep the top coat mix the same colour we measure everything in level buckets now.

Your ratios all depends on the size of your buckets tbh
