Combining indoor and outdoor paints

    Anyone done this for outdoor application?

    I've got a load of white ceiling paint and some sandstone colour smooth texture paint for outdoor use, I have two walls of a shed which is rendered with a quite smooth cement finish. The mix is probably going to need to be about 50/50 to do both walls (albeit one is facing away from the house so could be left but I'd like to do both) they face east and north so are relatively protected.

    Anyone done this and seen it survive more than one winter?

    I wouldn't chance the ceiling paint, much too soft and will go to chalk like finish if it is an unheated un-insulated shed.

    I wouldn’t use any interior paint on the exterior, even if it’s mixed in with exterior paint, wouldn’t stand upto the Irish weather.
    Probably lots of local sports teams, schools, men’s shed etc would be delighted to take your excess paint off you.

    I don't use the same paint for exterior and interior. Usually, water-based paint is a safe option for ceiling because it works well with poorly ventilated environments. Yes, its odour is also less. It also depends on which paint you already used for your ceiling. If it has oil-based paint then you will have to remove paints like any product from here at first then you can apply water-based paint on it. The use of sandpaper could also be a good idea but usually, it becomes hard to use sandpaper on ceilings.

    Moreover, matt finish of Leyland could also be a good idea for ceiling places. For exterior walls, I would prefer you UV resistant, breathable and water resistance paints. Such paints can help you for more than one season.

    I came in here to start the exact same thread...

    I've 5L of pure brilliant white matt cover emulsion to do the naked block wall along our garden, fear the whiteness of it might take a bit too much colour out of the garden... I've left over Colortrend satin finish in a grey tone we used for the kid's nursery, wondering about throwing in a bit to get a grey-white that might suit the blocks better? It's only a block wall so doesn't need to be the Sistine Chapel... would it mix alright and stick?

    Worst case. The satin will powder over a short time (First frosts) and undermine the whole paint. Wall would have to be stabilised before asking new paint to adhere properly. Ask around, somebody may have a small amount of an exterior colour you could mix in?
