Best Method To Clean Bricks After Building Works - How To Remove Mortar Stains OFF Bricks/Walls

[@RogerClubv]

Believe it or not, I used white vinegar and got the white substance off. I mixed equal part vinegar with water. Spray the solution on the bricks. Let it sit for a couple minutes brush it a little and rinse it off. That's it.

[@rupertthomson]

That makes sense. As far as I understand it's the acidic bit that does the work as mortar is alkali, so vinegar could be a nice cheap-possibly safer for people and animals-method.

[@specialandroid1603]

I did the same

[@ColinWasson-vj5pf]

It's really helpful. Excellent video.

[@dil4951]

Exactly what I need to do .. I wasn’t even searching for this 😅

[@PhilFeedback]

KZbin's algorithm recommended this video to me too

[@robertkennedy1666]

I don't know where you get your acid... We are using the same, hydrochloric acid, I don't know why, it doesn't seem to do anything.

[@easyneos]

will it work for the scaled boiler discharge water stain ? TIA

[@MrCardiffian]

There seams to be a centre long scuff or stain on every brick above the damp course. Is this a result of cleaing or design ?

[@cityofbadgers]

this will be the style of the brick, seen it many times before

[@monkeyboy4995]

Is it scratched from the head of the grinder used to install DPC?

[@quantumofconscience6538]

Many would recommend wetting bricks FIRST before the acid.... especially if the bricks are very porous. Probably not needed for a brick that does not absorb water, and has a "shiny" / smooth surface.

[@richardbrighton1686]

My bricks i have just repointed were very pourus. Did the saturating them over and over before pointing, added plasterciser and fairy liquid and made no difference. Added cement around 3 bricks and that's it!!! Had to tool it up and make it look pretty before moving onto the next 3.

[@DakaloMudau-v2j]

Whats the mixture on acid and water

[@1stwashandseal]

Use 1/8 acid the less the better

[@perseverancezengele7537]

Why should we not use a pressure wash afterwards?

[@ZRKREVIEWS]

@@perseverancezengele7537 chemical

[@diaconus1423]

Chemical? What does that mean, that you don’t want to splash the acid off the brick onto surrounding areas? Also what are we defining as pressure wash, is 1500psi too much, 2500psi?

[@AndrewHubbardBadger]

Why doesn’t it damage the mortar between the bricks?

[@texascaliber9929]

The mortar in between the bricks is a very thick compressed layer. The mortar on the brick is thin

[@mickyflakes]

Is this stuff good for removing salt effloresence too

[@ZRKREVIEWS]

Yes it is ive tried it and it works

[@1stwashandseal]

No mate , acid only to remove morter residue , for efflorescence you will need other chemical is called flurotech or lcr or efflock

[@bigkane1174]

Acid will 100% move efflorescence. Do not ever brush it on. Buy a weed killer pump. 2 litres of water and a quarter litre acid...spray on and leave...repeat several times. I've been doing it for 23 years

[@malwinawolanska9457]

when you pour to bucket always pour water then chemical lol

[@ZRKREVIEWS]

Your right my friend, water first checmical after

[@rngDeadEye]

I notice your bricks are quite sandy, isn't this why the big chunks are coming off easy?

[@nicolaemmett1402]

Where did you buy this cleaner from?

[@ZRKREVIEWS]

Toolstation or screwfix

[@bkn9939]

Is this affect the brick ?i mean the hydrochloric acid?

[@raywilson3166]

It can destroy some soft handmade bricks and isn really too.dangerous for DIY job. KZbin is full of amateurs teaching other amateurs how to use it

[@im2funky1]

Nice video!

[@tobycoleman2383]

Can you use this on Indian stone

[@ZRKREVIEWS]

Yes i would believe so

[@gregbooming]

No, you can't use Acid products on Indian Sandstone unless you are happy to see lots of iron oxidation. Your slabs can changed colour due to minerals (specially iron) and become orange/rusty coloured. Non acid product only.

[@Amit-ov3or]

Super video

[@ScottA2345]

You should always add acid to water - never water to acid.

[@AndrewHubbardBadger]

Why? Thanks

[@ScottA2345]

@@AndrewHubbardBadger If you add water to acid the water will explode and splatter. Always add acid to water. Best way to remember is to think in alphabetical order. A into W Not W into A

[@Blaze23557]

I have a lot on bricks ,too long to scrape

[@justinphilpott]

Or just use lemon juice...... it works

[@trymem8]

It says not for indoor use! Wish me luck I need to clean my red brick kitchen floor ! 😂

[@bigkane1174]

@trymem8 you do not need brick acid you need hypo....its a strong bleach. One pint hypo 3 litres water. Apply to floor and leave for ten minutes....mop it up with cold water

[@joemusic2882]

That’s some sloppy masonry work

[@nasirmir8771]

What chamical is this

[@illmitchjax]

You're meant to wet the brick first...

[@chrisrock1110]

Yep. You’re supposed to give them a quick wash and scrape off any mortar lumps. You want the acid cleaner working on stubborn shit, not loose stuff.

[@AJ-ds5gf]

Makes absolutely no sense to wet the bricks first. All you're doing is diluting the acid when it goes on.

[@illmitchjax]

@@AJ-ds5gf no, you're stopping the capillary action of the brick pulling the acid into the pores...

[@AJ-ds5gf]

@@illmitchjax LOL no. Adding water just dilutes the acid.

[@illmitchjax]

@@AJ-ds5gffor starters, you don't put brick acid on 'neat' anyway, it's meant to be diluted down to the amount specified on the bottle depending on usage and conditions. Secondly, a thin film of water on the substrate isn't going to notably dilute the acid... What it will do is prevent the acid being pulled into the brick by capillary action and potentially weakening the brick. You're only trying to remove mortar from the SURFACE of the brick...

Was it a plumber thatlaid these bricks? What an utter mess, I hope he wasn't paid!
