    Hi All
    I have had a water leak now solved, but the water stains its going to leave are going to need fixing. My father in law used a product before called Stain Stop but it went on quite thick and tbh it looked bad when he put emulsion over it. I have seen a product called Zinsser BIN
    can I roller this on lightly ? will it need 1 coat or 2
    How long to dry ? , it was the waste from the shower that had come off so water from a shower went down the hole between the floorboards and the plasterboards
    tbh I busy until next week will it be dry by then ?

    thanks

    Zinsser bin is the product to use. A few coats of that, a few hours drying time between coats is needed, and then a few coats of emulsion will sort it

    What about a coat or two of oil based paint - Gloss? Then emulsion.

    Not a good idea to apply oil-based gloss then emulsion on top. Too shiny.

    Oil-based undercoat may do, sometimes you can see patches grinning through the emulsion when completed, but this often disappears in a week or two.

    I too would recommend BIN or Blockaide by Smith and Rodgers. Both are pigmented shellac based paints.

    I would allow at least 30 minutes between each coat of BIN, a total of two coats, And then and hour or two before applying two coats of emulsion.

    You can either use a throw away brush with the BIN or use a decent brush and clean it with household ammonia.

    To assist drying, suggest if you have one or can "borrow" one get a fan to blow air over the damp areas, no need for heat just air movement.
