If it's not too late and you don't want to go the blueberry route, drain the

Leave it for a week or so, then refill.

Hello Marvo, been on your hols? Isn't there a preparation that you
can mix up and paint on with a wallpaper paste brush, I seem to
remember my father doing this but I can't remember what the stuff was
he painted on.
