    We want to paint but one hall wall is damp And we don't want to go through the costly lengthy process to solve dampness by opens I v and injecting walls to cure dampness which I believe is expensive and messy and time consuming . Unless there r newest easier quicker methods we just want to paint .

    I was told there are membranes to stop dampness cracking the paint so we can paint without fixing dampness

    Anyone know about these or about any new easier damp solving methods or methods to paint and to stop paint flaking from I repaired dampness

    Thanks

    You need to fix the failed dampcourse by injection method or some other way of replacing the dampcourse membrane BEFORE you attempt to paint. There is no easy way AFAIK.

    I'm with @Propertunity - you need to solve the rising damp issue as the moisture in the wall will cause the paint to fail (again). This will also cause long term damage to the cement render and to the brickwork if it is not stopped.

    Products like Krystol are a cementaceous wall treatment which forms a crystalline barrier which grows into the wall but does not form a smooth key for paintwork - @bob shovel might add his 2 cents worth as well.

    From previous jobs using this product, yes it works. Is it suitable for application on brickwork? Don't know as I have used it in subterranean lift pits.

    bunnings said they have something called damp stop
    but again they said the plaster has to be removed to exposed brick and then put the damp stop on all exposed brick preferably from both sides of the wall
    one said is a big built in wardrobe so that wont be happeneing
    and its double brick also
    they said to try it.

    they said that membranes are for showers to keep wetness out but if put where there is dampness in a wall they will rot

    damp stop is to stop damp going out and ruining paintwork but would have to paint on exposed brick

    so seems no easy answers

    last time dampness wasnt repaired
    we pained and within 2 months paint on lower half meter of hall wall was all flaking

    I'm on leave at the moment but agree the damp needs to be stopped first.
    Can you get under and put in a damp course membrane type arrangement? Can that be done? Call a brickie and maybe they can take out the mortar and put something in then re mortar

    8" ankle grinder, cut the lowest mortar joint of 4 bricks, slide in alcor, repoint up to 1/2 brick from each end. Repeat next 4 bricks. Lap the alcor over the other piece and repoint 3.5 bricks. Do other side. Leave a couple of days between each section.

    I'd imagine if the product is being applied to the damp then it would struggle to adhere in the first place.

    Actually, damp stop doesn't sound too bad - just had a look at it online.

    However, if it has to be painted on bare brick, then that is what you must do. No question. Might be a cheaper option than retrofitting damp course?

    Is there dampness in the walk in robe too?

    That's the go! As long as access underneath is reasonable it may be a good option.
