Frequently Asked Questions about FlexiDry and Floor Screeding

What is FlexiDry?
FlexiDry is an accelerated screed additive which can be used on a wide range of floor applications. The dry time of a FlexiDry screed is not dependant on a controlled temperature of 20 Deg C & 50% RH.

What is the difference between FlexiDry F1, F2 and F3?
It is the same liquid additive but by altering the dosage the dry time of the screed can chosen at 7, 14 or 21 days.

FlexiDry F0 is a different liquid additive which dries the screed in just 3 days ready for final floor finished to be laid.

What is the difference between FlexiDry and standard screeds?
Depending on the FlexiDry fast drying screed used, final floor finishes can be installed after 3, 7, 14 or 21.

Standard screeds laid at 75mm will take approximately 110 days to dry before final floor finishes can be installed.

12 hours to receive light foot traffic.

How quickly can it take general traffic?

Is it necessary to cure the screed under polythene for days after it has been laid?
No, unlike standard sand & cement screed and some fast drying screed additives it does not need curing for 7 days after it has been installed. This removes the associated H&S trip hazard with the polythene, means no revisit to the site to remove it and also saves the issues of its disposal and the environmental impact.
