Painting an exterior wall with bubbling and peeling old paint.

deeksofdoom

My house is about 14 years old at this stage. In its lifetimes it's had about 4 paint jobs done on it. In the last few years the paint on the front of the house(which is the most exposed side to the elements) has been blistering and bubbling off the walls on the outside.

It's like the paint is all about to peel off seems to be a rippling effect. I was talking to the local hardware store boss and he said to take all the paint off with a type of nitromors for exterior paint, wire brush the plaster of all the old paint and then give it a couple of coats of a polybond type of stuff, then repainted the house.

Does anyone have a similar experience of doing this type of job and did it work, any advice appreciated.

Get a scraper and remove the loose flaking paint. Feck that nitromors lark - that's overkill. Once the loose paint is removed, get yourself 5-10ltrs of stabilizing primer (approx €30 for 5ltrs and widely available). Paint this on with a roller/large brush. Next day apply your topcoat. Thats it.

I started going at it with a scrapper already and it's taking it off the paint fine. Should I wire brush the wall/ powerwash to get all the old paint off or would that be overkill too?

I had the same problem a few years ago but the more i scraped the more paint was flaking off so i power washed the whole thing back to the rendering.
Let it dry out primed it and two coats of good exterior paint.

Its still perfect will do another few years.
The neighbour done his house at the same time but only done a half assed job and hes back to square one already.

Scraper and power wash is the way to go. Stabilising primer is then key.

and get a good paint, colortrend is highly rated.
