What tips/advice for post treatment of liquid screed please? (Done by ScreedIt using locally sourced screed mix)
A google suggestions:

Laitance should be removed by light abrasion using a suitable sanding machine i.e. a rotary floor scarifier and a 60’s grit sandpaper. Remove excess dust completely with a vacuum cleaner. Abrading the surface is best carried out 4-6 days after the application of the screed and can assist in the drying out process. Scarifying the surface is even recommended with low laitance Calcium Sulfate/anhydrite screeds as this further aids adhesion.
Anyone done this, anyone done any different? Any tips much appreciated
