Painting damaged rendered wall of house & removing old paint

[Twentyfour7]

Hi All

I need to paint the render/ wall of my house that had ivy growing up it.

It looks a bit of a mess (see photo) and I think I will have to somehow remove the original paint which is flaking off and sound in some areas, or paint over it . But I am concerned just painting over it will not cover the flaking / patchy areas .

Any ideas on how to go about this and what products to use please?

Thanks

I'd jet wash it, then wire brush it, then jet wash it again to remove any dust / loose bits.

And then call in a rendering company to re-render

Hello
Would a normal cold jet wash remove it and not damage the render or would it have to be a steam jet wash?
Thanks alot

The idea of the jetwashing is to remove anything that's loose - a decent cold jet washer will work but don't go overboard on pressure - a car fan spray attachment will be fine. If the render itself is failing, rather it fall off now than after a harsh winter and all your new paint falling off.

I think the render is fine. Would it be worth using some sort of paint remover as. I don’t think the paint will come off with a pressure washer alone, the paint that has not been affected by the Ivy is still very sound

Whatever you do will always be more work in the long run.

Any properties we bought that were rendered had k-rend applied over the top.

Not cheap but never had to paint them again.

Hello

have a similar issue with section of wall of a garage; the paint is slacking off and I need to repaint , whats is the best way to do this?

I ended up removing as much as I could with scraper/wire brush and then just painted it again, it doesn't look too bad

Giving the bald areas a coat of PVA will help seal the edges of the paint and give a key for the new.
