Fill Coat DA
How to apply.
Check if you need it
Run your hand over the cured microcement. Rough enough to catch a cloth? Use Fill Coat. Already smooth? Skip it.
Prep the surface
Fully cured, clean, and free of dust, oil and grease. Sand and wipe down first.
Stir it well
No mixing, no Part B. Stir thoroughly before you start. Working time is 60 minutes.
Trowel one thin coat
Plastic trowel, one thin pass. You are filling pores, not building thickness.
Dry, then seal
About an hour to dry, then sealer as normal. Apply between 41°F and 77°F.
One coat, before the sealer.
