Block and beam grout/slurry wetness

[bandejapaisa]

I need to cover a block and beam floor in the grout/slurry mix. I'm unsure of how wet the mix should be.

I read that it needs to be brushed cleaned and wetted beforehand, and then a 4:1 sharp sand cement slurry needs brushing on.

How wet/dry is this slurry?

Does it have to be sharp sand? Will builders sand work fine.. cos I have a lot of that.

Builders sand will dry out too quick.
Wet everything first.
Mix it like pish and brush it about.
Don't leave any clumps about.

So it can be poured out of a watering can.

There are 2 parts to this, well there was when I did it

- Mix cement and water into a slurry, so its pourable, and cover everything with that. This will help lock the blocks together.
- After thats dried (not long at all), make a 4:1 mix of cement, sharp sand and feb mix. Needs to be pretty runny, so it can easily be pushed around with a broom, to fill all the gaps, and needs to be workable for about 15 minutes. Trial and error here, my first batch was a bit stiff and really hard work.

Do 1 plasterers bucket full at a time, no more, unless there are more than 2 of you. I mixed it using a paddle in a large SDS drill.
