    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
    Mike
