Paint exterior wall - current paint peeling

trickybicky

The paint on the front of the house is peeling off, i want to paint it. Not sure what paint was used originally.

Should you peel all the paint off the wall before repainting? Do you need to sand the wall if there are any bits left?

I have attached some zoomed in pics of the current wall.

How do you stop paint peeling?

Powerwash the walls, whatever comes off comes off. And then prime bare patches with alkali resisting primer, then put 2 coats of your chosen paint colour over the primer.

Thanks, for the suggestion, with the hose pipe ban I won't be able to do any power washing any time soon!

I can also picture it being a bit messy and could end up having paint peeling all over the neighbours cars!

A slightly messy job but much quicker and easier than trying to scrape it off.
If any of the paint is solidly stuck on the wall it doesn’t need to come off, only what’s loose.

Had a flacking front wall of the house and garden wall
In Spring I did blow all of the paint off the wall with full blast of a powerwasher
Just only remove the lose parts and painting it looks ****ty and took me two days to get all of the paint off but it looks a new wall now
Won`t work with a D I Y washer , rented a professional one with a extreme high pressure
Stay away from the windows you will blow the glass out

ask the neighbours down wind of your house to move their cars up the street
after removing all the loose paint, put a stabiliser on the wall before painting
Had same issue 10yrs ago, did the power washing, its a messy job but worth it
