Truscreed

[macten]

Just been to look at a 20m2 wetroom/changing room/bathroom combo.
Screed went down on 10th Dec and got the owner to dig out the delivery note to help me identify the screed which is tarmacs Truscreed.
She said it went down pretty much dry and was then compacted with a machine.
Looks nice and flat and seems to have lots of reinforcing fibres/polymers in it. Not sure of depth but appears to over a DPM.
Wondering what prep work is involved - will be 60x60 porcs. Do I treat like a sand/cement screed or is it more involved?
Anything to watch out for for this type of screed etc...
Ta very much

Are you sure its Truscreed and not Truflow ? Thinking it went down dry would say Truscreed which is OPC based so, abrade prime and tile !...If its dry of course which I doubt it would be at the moment.

 

[macten]

Definitely Truscreed.
OPC - is that portland cement?
So it's not an anhydrate type screed then?

 

[Gazzer]

OPC, Ordinary Portland Cement
Yes a sand and cement screed.

What size ytrowel also Neale or is it dependant on the state of substrate?

 

[Gazzer]

I use a Tiger trowel for that size tile.

Neale - what is the purpose to abrading this screed? Is it to remove any latency? Just that I've never abraded sand/cement based floor before.
What do you use to mechanically abrade in those situations?
Thankyou

I thought I would amuse Alan ( Ajax) :smilewinkgrin: , I have never abraded a sand and cement floor, just clean it from dirt...plaster and other builders mess then prime and tile.

For abrading Anhydrite screeds I use a 17" floor scrubber polisher at about 180 rpm with a sanding disc.

Well..... We are not amused.... to be fair though very few sand cement screeds get abraded even though the advice is that they should. Yes truscreed is Tarmac building products branded sand cement screed so treat it as such.
