bucket slurry - domestic work

[NickB_99]

Hi all

When washing plaster buckets out, you always end up with a thick plaster slurry at the bottom.
Ideally you don't really want to tip this stuff down the drain, so where do you guys ditch it - esp when doing domestic work ?

get the bucket as clean as you can by putting the unused plaster in the empty plaster bags then fill the bucket right up with water, give it a good clean and swirl and tip the plaster away, there shouldn't be much residue left really and with a few good buckets behind it then it wont cause any more of a problem than anything else going down a drain.

Also , gypsum is soluble in water, so will break down.



I always have a cleaning bucket, similar to a big skimming bucket to wash whisk in and use that water to clean out buckets. At the end of the day, or the next morning, you can tip off the top clear water when it is settled. This clear water can be used to top up a trowelling bucket, for mixing or to rinse out whereever you tip your waste.


If you have nowhere to tip this waste, after taking off the top water, you can bring it home as it is now easily kept in the van in the cleaning bucket, unlike a load of dirty water.

You can also put the sludge into a bag. You can make this easier with a couple of handfuls of finish or bonding etc mixed into it with a guager or stick to thicken it up.

Put it in an empty plaster bag, and put this in a plastic rubble bag.

Thanks Micilin.
I do use a bucket for my mixer (as you suggest), but to date have been tipping the slurry round the side at home in a scrubby bit of land.
In the interest of process improvement, looking for a better solution.
A lot of tips there - thanks

Interestingly there seems to be a crossover point between where a water/plaster mix sets, or just remains a runny mix and washes away easy...
No idea what concentration this is tho.
