I mixed some b&Q plastering sand with some cement and feb. It mixed up quite easy. I put the mix into the ritmo to see if it pumps through.
If it pumps through that means the gear is pumpable.
It flew through.

1 bag of sand is 33 quid cement is 3 quid odd feb is about 7 quid. that will do about 60 mts at 10mm

You can use this mix in all sorts of applications. for EG

Base coat internal and external

add SBR for rendaids, base coats that bond direct to old work or overlay

add lime for base coat for roughcast and sprayed texture roughcast that can be painted

add lime dash receiver or floated topcoat

add lime white cement dash reciever



it does tie one man to a machine and mixer so thats not a plus.

after 50 seconds turn it off i forgot it was recording

Whats it go through pipes like?

Surely you wouldn't be able to mix quick enough to load the ritmo going full speed?

It its sprays alright then result :)
 
what it proves is that this machine can do more then any other machine on the market, yeah it does tie 1 guy to the machine but if you was doing it by hand you would need a guy on the mixer.
 
will it pump at full speed and through pipes?

tbh youd have a guy on the machine pretty much full time anyway when bagging so not much more labour.
 
fuckk me you lot dont want much do you. I have to order the plastering sand bags in special in my b&q so dont hold your breath for another video unless our normal sand works.

It should go through the pipes just fine. if a mix is not pumpable it wont go through the rotor and stator.

The ritmo pumps Max 14 lts a belle can mix 90 ltrs a batch. so should last 6-7 minutes . so if you had a hopper full, a barrow full and a mixer full you should have enough time to keep up. labourers been doin it for years. or if your ploughing it on then 2 belle mixers or a diesel. or a batch drum mixer.

You are talking about sand cement site mix here not bags of ready blended so expect a trade off. Cheap material = more labour
 
because its plastering sand. its supposed to not bleed water. TBH the sand looked exactly the same as the building sand we get down here. I will give it a go when i get chance with normal sand.

PS anyone with access to b&Q sand is also welcome to give it a try like innit
 
The only thing I don't like about having my machine is the lad on the machine has it to easy in my opinion.all he has to do is load a few bags in and keep a eye on things.not like back in the day!!!
 
we are "Back in the day" at the moment. Back of a terrace render. I got those 2 boys mixing and laying on traditional style in a belle, barrowing it to the scaffold and bucketting up the scaff. Prepping a job for sprayed roughcast but didnt want to spend a fortune on gear to straighten it out. He has to I frame his roughing its so bad. Still we gotta start somewhere.

They don't believe that 1 labourer would keep 2 spreads going all day. They think that its 2 labourers to keep 1 spread.

Nice change to be honest to have a small bill for 3 ton of shish

Get an extension hopper (7 bags) and get him spraying
 
I am interested in this! So sand and cement with feb as usual. Maybe a bit on the wetter side? No water setting.

Mine is a monojet 3 phrase so a bit more power.

Why has no one done this before? Sound too good to be true.

Try it. go to b&q get some plastering sand
 
@PFTwales even the bags of plastering sand have the odd rouge stone in them, what's the worst that could happen if one goes into the Ritmo Ian? Will it wreak the stator or damage the gun? If it really is viable to use site mix through a Ritmo I'd use mine quite a bit, having to use expensive bagged materials is the biggest drawback with it IMO.

B&Q sell plastering sand in 850kg bags. I would imagine that the sand is more local to your B&Q rather than from 1 quarry and shipped all over the Country.

My plastering sand is quite good, sharp and clean. Been using a sand today from Heckmondwike and really nice stuff. 40 miles away though.
 
i dunno where it comes from but my b&q say they have to have it delivered to their depot and then want 20 sovs to deliver it unless i spend £100 +
maybe the bag says its origins
best thing to do is buy a few 25kg bags. mix it up and try it. if it dont pump try it with lime or source other sand

quite often more than 2 aswell!

It wont damage it
 
Wasn't it a bit of a gamble wondering if it would work and then just going for it? A bit like saying, "I wonder if my Mercedes S Class works underwater" and then driving it into the sea!!
 
not really. i understand the basics of how a material is pumpable. when i saw the mix i tried a bit,then when that went through tried a bucket full. If it was unpumpable the water would have come to the surface of the material in the hopper due to vibration.
 
I can get hold of a cement with lime and feb already in it. Saves mucking about batching.

Going to give it a go when I have a suitable job to experiment on.

Tried something like that it don't go through the pipes. Maybe u will have more luck?
