Any tips for preventing cement sticking to the inside of a cement mixer? I clean it out after I've finished for the day, but poking about inside it with a spade is a pain!

Wash-out with water, then lob in some stone chippings or gravel and some more water and leave to run for 5 or 10 minutes and empty out. Cleans out a lot of the rubbish.

Thanks - that advice is much appreciated.

There can be as much as half hour intervals between using it during the day - can I use the same load of gravel each time???? Then use it again when I've finished for the day?

You only clean it once at the end of the day - so the contents don't harden overnight.

You don't clean it between mixes - even if there are long intervals.

Thanks Woody.

I've been mixing/pouring foundations today (I'm so tired I can hardly think!) but the wretched thing has been getting more and more gunked up. I've had to scrape it out after almost every mix otherwise it gets so heavy I can't control how much to tip out - I don't tip out the whole load or the barrow is too heavy!
 
Concrete should not really stick.

Put the water in first (let it spin a bit), then add some sand/gravel (this will scrape the drum clean) then add 1/2 the cement/ then add the rest of the sand/gravel and then the last bit of cement. Then top up with water, if necessary and let mix.

I would mix this quite wet so it can be placed easier.

You may also just want to mix a barrow load at a time, and not fill the mixer.

When you have emptied it into the barrow, before you go and tip it, put the water in the mixer and let it run so that it washes the inside down ready for the next mix, then go and tip the barrow. And then switch the mixer off if you want.

Idealy between mixes, you don't want to let the contents remain around the sides of the drum to stick and start to go off, so by adding the water it cleans the drum and keeps it smooth ready for the next mix.
 
Providing that your sand/stone is fairly dry then chuck a full bucket of water in first.
Sounds like you're starting off a bit dry.
And Only clean out at the end of the day.
Or if your finding it hard just do half mixes, your mixer will like halfs too.
 
Thanks for the replies - they've solved the problem.

The next problem is bricklaying! Any ideas on how to build walls with an angle of about 60 degrees?

use a triangular fillet taped to the level.

You mean 60 deg vertical?

No :eek: A horizontal bend! A corner!

That oblong shape is an old pond from which one side has been dug out. The diggings extend along the lower level of the patio, diagonally. So on the outer corner of the pond will be an angle......or corner.

How do I do that?
