4-1 Mix with a splash of Opti- mix ( feb) scratch coat 1/4" .few hours later apply finishing coat and float up. Wet the wall well.

Slightly wetter but not to wet so it slides downd the wall.

ok before i start to put scratch coat on, do i seal wall with upa and let dry?
ok if i put in steps can you copy and paste correct way for me?...

seal wall with upa.

fix beadings.

wet wall well.

apply scratch coat approx 1/4" thick (slightly wetter than pointing cement).

allow couple of hrs to dry (when dry enough) and then wet wall again.

apply fininishing coat.

is that correct or have i missed or inserted something wrong please
best regards
