Another house painting thread.

A Law

Seems to be the rage at the moment! Read a few threads about painting your house. One of the things I took from it was to power wash the house first. Some of the paint started to come off, the more I power washed, the more than came off! I reckon I could take all the paint off if I keep going which I don't want to do. I'm not even using the lance and it's a basic nilfisk power wash. Will I just wire brush and use a scraper on the patches and then apply the paint? Fairly clueless so any advice is appreciated.

You need to take it all off. It'll never look right if you don't and if its handy enough to take off then why not.

If it's coming off that easy it will most likely pull away with new paint.

You need a good surface to bond with.

Looks like it was painted before and at some point more recently got a 'lick' of a one coat refresher. Personally, I'd take off the loose paint with a scraper and then apply one good coat of stabilizing primer. Allow to dry and next day apply 2 coats of a good quality masonry paint. Job done, and the paint wont budge. The primer is the key.

Really don't fancy having to powerhose the whole house so think I'll go with that alright dodzy. Thanks all for the advice.

Stabilising primer will only stabilise chalky powdery paint. If there is loose paint beneath it, the new paint will come off. I would bite the bullet and continue powerwashing.

You will regret not doing it properly. I learnt the hard way, albeit it was a bathroom ceiling where some of the paint was flaking off. I scrapped off the really loose stuff and painted. It continued to flak off in the coming months as the new paint was stuck to the old paint which wasn't adhered to the ceiling. I eventually done it right.

Hence why I suggested removing loose paint with scraper. The power washer is the man for the job but the flakey paint tends to go bloody everywhere. At least with the scraper, it’s contained somewhat.

How will that stop the rest of it coming loose ? Because the rest of it will suffer the same faith.

None of it had come off. I got too close with the powerwasher initially. I'm presuming paint shouldn't come off that easily. It's a 120 bar nilfisk

Any paint can come off with a pressure washer tbh. Depends on distance and pressure.

Scraper. Loose paint off. Primer. Simple. Never fails. Obviously, the power washer is better, but the former is more than good enough.
