    We asked an artist to paint a mural on the side of the house. The artist
    used acrylic paint for the mural, about 4x6 feet. The background is water-
    based house paint, acrylic or latex (Kelly Moore).

    Now we want to put on a clear coat to protect it from dust. I have a
    spray can of Deft lacquer and also some Deft liquid. Will that be
    satisfactory, or do I need something else?

    TIA

    Dont use laquer, its to hard a finish, the latex will flex and move
    more than the laquer, its not UV stabil, it might yellow from UV, it
    might not bond well, it may likely eat at the mural as it cures, which
    is likely latex house paint, why not ask the artist or call the paint
    co that made the paint he used, I dont know if anything will benefit
    the mural but it has to be UV stabil and that means a UV marine type
    varnish but clear coats never last as long as solid colors, maybe
    nothing is best. Are murals usualy clearcoated? I think real laquer
    will peel in sun in 3-6 years and house paint done right might be fine
    for 20

    correct. i had a mural on my house (8'x60') and the artist used spray
    lacquer on parts of it to protect some of the bright colors in the
    foreground. it was completely under cover, but turned yellow/brownish in
    about 4-5 years.

    you need to find a uv stabilized clearcoat. most of them are already yellow
    or amber colored. i haven't ever seen a water clear one but they may exist.
    you might try calling a major paint manufacturer, like krylon or rustoleum,
    or stop in a real paint store, and ask.

    Talk to a pro at an auto body shop. Clear coats on cars are tough, UV
    resistant and stable, even allowing a bit of flex. If he tells you its
    hopeless, take him at his word.

    Clear coat for a car might be as flexible as any regular spray paint,
    and you wouldnt paint a house with it, it just doesnt flex exough. he
    used house paint, you dont clearcoat a house, the clear wont last as
    long as the paint. No clearcoat lasts as long as a paint, the products
    are missing that makes paint last.
