Drying time for concrete floor screed

How long does concrete floor screed take to fully dry? Can I speed the process up at all?

"You can’t speed it up, it should be left for at least a week before laying flooring, it can take longer depending on thickness if tiles are being layed."

"If you have not screeded yet then an additive such as Retanol Xtreme or Mapei Topcem can be used which will allow screed to be walked on in 24 hours later and can be tiled on of covered with other coverings as little as 72 hours later . This is as per manufacturers literature and I can confirm these products work from the many projects I have carried out.

If the screed has been laid already and is a Traditional Sand and cement screed then Set time is twenty four to forty eight hours Then Allow 1mm per day x thickness before laying coverings but use a moisture meter to check. I Do not recommend dehumidifiers or blow heaters as accelerating the drying process could cause the screed to crack/shrink/curl and a costly bill to rectify.

"Allow 1 day per 1mm of depth. You could use a de humidifier with the windows shut. Alternatively leave window open to let moisture out of room whilst drying out. Best to let dry out naturally in my opinion. Could have used a quick dry screed product to avoid all the waiting initially"

"Best to let it dry natural in warm conditions one week usually in the cold temperatures try just putting a heating unit in to keep temperature up"

"A screed laid on an internal concrete floor can be walked on after 24 hours. However if your question refers to when can you lay tiles or a wood floor. You may need anything from 2 weeks to 3 months, depending on material.
I would advise you to speak to the supplier prior to laying the screed. As there are products that will speed up drying times."
