Non latex self levelling over green screed

[garyo]

Is it okay to lay 2mm of self levelling over the top of 3 day old screed? Normally I'd think the wetter the better to keep the suction down and making it self level better, but I wonder if it will prevent the screed from drying out?

Cheers

The self leveller is permeable, just cement really.

Great. Out of interest is latex stuff the same?

More or less. If you are thinking of using a latex product on wet screed, just check that it will bond to a damp surface. I can't see why not, but check first.

I think you're heading for a disaster. The screed drying, and will start to get dust on it. You need to apply an acrylic primer to seal the dust in, but as the screed isn't dry yet, then the primer may delaminate.

The screed won't get dust on the surface if the surface is covered with say the OP's self leveler.
