Sand/cement Screed Aftercare

[jayc89]

I finally got around to finish off the last part of the house that still required floor screeding yesterday. This morning it's looking pretty good - haven't walked on it yet.

Should I be doing anything else with it? Water mist and/or covering with a sheet of DPM for the first few days etc?

As it’s inside there is little chance of rapid drying through sun or wind so nothing required

Our builder covered it with plastic even later in the year. The heat it gave off made the house warmer inside.

You can hose it down or throw a few buckets of water over it 

I’ve tiled on screeds that have been laid for only a few hours 

Traditional is pretty bombproof

Wouldn't that trap any moisture in the screed? I thought the rule of thumb was 1 day for every mm of depth for traditional?

 

Given it's been down for 24 hours now, is it good to be walked on so I could spray it with water? I know most places say leave it 48 hours before light foot traffic.

I've had a walk around now and there are a couple of areas that I'm not happy with, not massive, probably 5-6mm deviation in total. Can I use a concrete grinding disc to sort out the high spots?
