/diy/ - Do It Yourself

Close Up

I have had success with white vinegar but not in relation to bricks. You said you've used vinegar but is that specifically white vinegar?

pressure wash

to prevent it use a silicone based penetrating sealer for brick

i wouldnt even bother though. pressure washing is fun

Tried pressure wash. Took off chunks of brick but not the deposits.

Yeah, it was white vinegar but, as another poster said, probably any vinegar would work (or not work) the same.

>Probably caused by water leeching through from the other side.

ground level is higher on the other side?
What might be happening is that leak starts from the top and levels down in the center, have you checked for leaks on the top?

>>1701237
Dude, there's trees on the other side.

>>1701244
Could be a raised flowerbed or his neighbor has lawn sprinklers that soak the wall

>>1701114
Is that not graffiti that has been badly removed?

>>1701114
You won't be able to with that amount of build up. Well, it will be cost prohibitive.

>>1701237
Oh no no no motherfucker... This is fucking brick, and absolutely nothing even slightly negative could ever happen when using brick! Get your shit straight.

>>1701237

Ground level is higher on the other side. A foot down from the top in fact. No way to fix that. I just want to know how to clean it.

Bump

acquire a pressure washer with high adjustment capability
also get a rotary head instead of nozzle

Hope whoever built it knew what he was doing.

Use Lye or whatever the fuck they call NaOH there, dissolve about 1Kg of the strongest you can get your hands on in a big bucket and use a broom to cover the whole wall, and then wait. You get better results in sunny days.

>tfw upstairs had a leaky pipe years ago
>tfw that shit is still over my front wall
It's not actually my wall though (council) so I dont know if I'm allowed to pressure wash it.

visual crimes aside, the council would murder me.

muriatic acid. mix with water 5 parts water, 1 part acid. use a brush to scrub the mix onto the wall. let dwell for 15-30 minutes. rinse off. use a wire brush or scraper for the stubborn areas

>>White vinegar, also known as spirit vinegar, has 5-20% acetic acid. This is generally higher as compared to distilled vinegar’s 5-8%

Vinegar is not the same. I had a job cleaning a food prep area and learned we had to use a specific type because of the % acetic acid.

Heh. Very unlikely. The whole house is full of lazy shortcuts, cheap materials, shoddy workmanship, poor planning, etc. I'm just trying to deal with the fallout.

I don't understand this. The deposits are most likely Ca(OH)2. It would seem you need an acid to oxidize it, not another base. Maybe some chemical anon can help.

>>1702169

I did this. Didn't work. Tried several different dilutions up to 1:1. Doesn't touch it.

>>1702431
how strong was the acid originally?
30-35% stuff diluted 1:1 should have easly etched that out

>>1701115
>no bond
i hope its not single skin wtf
>>1701308

Look for a product for removing efflorescence.
