Exterior paint issue

tsue921i8wljb3

While washing the exterior walls in preparation for painting I have come across several spots where the previous layers of paint are literally peeling off down to the plasterwork. I have removed as much as I can.

My issue is now if I paint the walls as is I am going to be left with visible patches where the new coat is much thinner than the old layers. I mentioned this to a friend and they said a product exists that can be applied to even out the layers. Unfortunately they did not know the name.

Does such a product exist and if so what is it called? If not is there anything else I can do to resolve the issue?

Unfortunately you're gonna be left with patches. I've never heard of a product to fill the gap where the patches are.. Load on some paint a few times with a brush before you roll, let it dry, and repeat a few times..

Hopefully it won't be too bad. Any pics?

Thanks for the reply. I thought it was too good to be true. I'm not at home today so I don't have any pics.

I think you may have heard about a stabiliser solution which is applied to flaking paint. It will not act as a filler so you will still have the gaps where paint has peeled off. Afaik the only remedy is to replaster the wall.

Perhaps that is what my friend meant. He is not in the trade so may have been confused. Thanks for the advice.

Sorry if this is a stupid question but would I paint the primer mix just on the bare patches or would I use it on the whole wall? Thanks again.

When I did mine I painted the whole wall, as it also prevents flaking.
But I guess you could do that too

Just checked my original comment, the primer is mixed with your paint, 1:1 or up to 1:5, depending on bad the old paint work is.
That is then your first coat of paint.

had similar problem recently
removed the flaking paint
sanded wall with a electric sander with a sand pad suitable for concrete walls to smooth off any differences in the paint left and wall
painted the exposed wall with stabiliser solution and onto the paint left
painted wall with brush twice to build up paint on area that was exposed
then went over whole wall with roller.....will even out the more paint layers you put on
