Masonary Paint Removal
Need to repaint the outside of the house, the old masonary paint is
flaking off, though some bits are still sound. Manually scraping or wire brushing two windowless, 8m wide, two storey gable ends and another 10m wall doesn't appeal... I'm thinking that a compressed air driven needle gun is the way to go but not sure how vicious (or not) such a device is. The substrate is stone and the pointing may well need looking at and chasing out in places before repainting. So is the needle gun a good idea or is there something better out there? -- Cheers Dave. |

Masonary Paint Removal
A pressure washer can be fitted with a sand blaster attachment. That
may be too severe, or at least risks brick face damage. However I'm sure Tommy Walsh had an angle grinder (looked like 9") with a large flat disc with a pad on it which was specifically to remove paint without damaging the face of bricks. Once the face has gone you are screwed, a few wet winters will trash them quite quickly. The material on the disk was arranged in a raised spiral pattern, I suspect not too different to a 3M Clean n Strip disc - but much harder because they wear down very quickly when removing even small paint spots from brickwork. |

I took mine off a rendered surface with paint stripper (generic brand from a trade outlet rather than the Nitromors). Took about 15 litres IIRC. Piece of cake if the wall is flat. Forget it otherwise. |

They're stones, not bricks. Having it professionally blasted would be ideal but as you can imagine this is going to be expensive. manually with a wire brush is going to take forever. Which leaves mechanically, and doing it with a needle gun wouldn't work neither IME as I think the needles would just compress spots of paint into the stone. http://www.brandontoolhire.co.uk/dir...p?idproduct=74 Is a grit blaster /pressure washer and can be had for about £50 a week, although I'd be a bit wary of water ingress, especially if it requires repointing in places -- Phil L RSRL Tipster Of The Year 2008 |

I've used a needle gun on mine, but of course it doesn't do a very big area. Good for getting off the stuff that's a bit flakey but won't actually fall off. To my mind, if the gun won't take it off you can paint over it. It's also not bad for digging into some of the irregular pointing on my random stone, if that's what you have. I'm repointing with lime mortar and painting with home made lime wash. |

I shall probably remove all that render as the rest of the wall is bound to go the same way. -- Cheers Dave. |

I think you'd need to add the hire of a suitable PW onto that £50/week though. As there is quite a bit of "growth" behind the flaky paint a good wash down of the wall is something that will have to happen anyway. although I'd be a bit wary of water ingress, especially if it requires repointing in places Ha, we get proper wet up here driven by storm force winds... not quite the same as a PW but a lot more than most buildings get exposed to. -- Cheers Dave. |

Te issue is to remove stuff that would likely fall off anyway, then the new pain will fill all the gaps that are left. In essence all you want to do is hit the paint harder than the wind and weather will in the future. Pressure washer is perfect for that. |

As I see it a wet blaster is just a pressure washer with some abrasive in the water flow. The picture in the link shows a normal PW lance with the grit attachment on the front.

Serious stuff! I'd at least do a small trial with paint stripper before embarking on something that drastic. In my case it lifted the paint layers from the masonry quite neatly. Even on an irregular surface, and left to dry, it may well flake sufficiently to make it easier to remove. |

If you're using portland cement and stone then its non porous so why have a breathable paint? One reason for lime mortar is that it's softer than stone, so if the building settles then the pointing gives way, rather than the stone cracking. It may be a good idea to use a softer sand with portland cement. so that it will give rather than the stone crack. perhaps [g] |

Over time water will get bhind the paint layer I'd rather it had some chance of getting out rather than sitting there and either making it's way inside or freezing damaging the stone or paint layer. We had some quite long periods (weeks) of consecuative "ice days" last winter. Days when the air temp didn't get above freezing and overnight mins of -10C. One reason for lime mortar is that it's softer than stone, so if the building settles then the pointing gives way, rather than the stone cracking. This building has probably first built about 300 years ago, don't know if it has been rebuilt since. Apparently it was a delerict shell 30 or 40 years ago. It's not likely to be still settling, it's almost certainly built directly onto the bedrock as well. -- Cheers Dave. |

Manually scraping or wire brushing two windowless, 8m wide, two storey gable ends and another 10m wall doesn't appeal... I'm thinking that a compressed air driven needle gun is the way to go but not sure how vicious (or not) such a device is. The substrate is stone and the pointing may well need looking at and chasing out in places before repainting. So is the needle gun a good idea or is there something better out there? -- Cheers Dave. Hi Dave, Don't know if you'll pick this up. This is spooky. With a name like that you could be same Dave Liquorice who came to fix my organ in Devon in 2014? If you are, Hi. Anyway, I hope you succeeded with your masonry paint! Just for the record, I had a similar problem and used an electric needle gun I hired from Speedy tool hire. It worked well, but was slow and hard work. Cheers John |

Pressure wash to get rid of the loose stuff. Paint over the rest of it. |

Lonely Psychopathic Senile Ozzie Troll Alert! LOL
On Wed, 10 Apr 2019 03:58:26 +1000, cantankerous trolling geezer Rot Speed,
the auto-contradicting senile sociopath, blabbered, again: So now we all wonder what was wrong with his 'organ' He kept playing with it and it fell off. He was warned about that, but wouldn¢t listen... Adam has the same problem. Spare everyone your pathetic attempts a "humour", senile Ozzietard! -- Sqwertz to Rot Speed: "This is just a hunch, but I'm betting you're kinda an argumentative asshole. MID: |

Don't worry, after almost 9 years I'm sure the original paint would have flaked off by now, and even its replacement will probably be up for renewal too. The replacement is still good, though not pristine due to lichen and algae growth. The gable end that was previously rendered is a bit iffy in places, I don't think I pressure washed that after removing the render (which was almost totatly blown), that may have something to do with it. -- Cheers Dave. |

Where are you getting this ancient post from ?. Maybe 9 years for op but I have a similar problem that I need to sort when the weather gets a bit warmer. My property has probably 5+ layers of masonry paint. 80% appears sound but with the other 20% some of the top layers are flaking off leaving sound layers beneath and in some areas the paint is no longer sticking to the bricks. The latter I think is mainly where the brick surface was spalling prior to being painted and are the odd bricks randomly scattered around the wall. A question to those who have used a pressure washer: Was it used to get all the paint off or just the loose paint? My intention is to repaint with the same colour (white) after making good any dodgy areas. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

My intention is to repaint with the same colour (white) after making good any dodgy areas. I'm very interested in the answer to this too. My house is roughcast rendered with nearly 80 years-worth of paint on it and in need of a re-paint. Some of the paint is still well attached, but some isn't. |

Anything that that doesn't come off with the impact from a rotating pencil jet of a pressure washer at 2" or less isn't going to come off anytime soon. Beware that if the mortar is a bit iffy the pressure washer will have that out as well... It's very messy job, you'll get soaked and filthy from paint flakes and anything else that detaches from the wall. Paint flakes will travel considerable distance given a chance. I had proper scafolding put up(*) which made access very easy and gave something to attach tarpulins to behind the work area to contain the flying paint and water. Also cover all the ground under the work area and at least a couple of yards either side. (*) Well worth the £2,000 or so it cost for 6+ weeks. That was for full access to three two storey gable ends (3 levels) and 10 m of two storey wall (2 levels). -- Cheers Dave. |
