How to acid clean bricks with a pressure washer 

UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ru-vid.comUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.

Look at him blasting them bricks up close what a mad man 😂

Respirator with acid cartridge is what you need, a dust mask is for dust.

would acid remove any tint that I had been applied on my brickwork? the tint was to blend two different colours of brick that my house was build with.

It looks the exact same as before you started it lol

You have a good bricky clean and tidy layer with a good eye Make cleaning way easier Good work

Good training video. It helps.

You can neutralise the HYDROCHLORIC acid with bi carbonate soda too I think. Many brick manufacturers have advice on preferred methods for their bricks.

Pressure washers actually drive the dirt further into the brick and is not advised. A regular hose is what is necessary.

Great audio. Thank you.

Can this method get rid of old ivy plants that have left marks on the brick?

Ho.....If you leave it for 2 months after laying the bricks.....Can you still get the same result....Or would the mortar hardened and it would now stain ? Is it same work or more expensive to clean ? Thanks

What ratio acid/water ? 10:1 ? 20;1? 50:1 ?

I Hate Seeing Masonry Pressure Washed. There's an Industrial Park Nearby Lined with Brick Buildings. It's Easy to See Someone Went Down the Street Pressure Washing. Some Are Completely Covered with Efforessence From the Pressure Washing. Some Buildings There Are Older than Others. They Never Had the Efforessence Before Whoever Washed them Did it. Pumping Water Into Masonry Is Never a Good Thing Unless it's a C'ment Pond.

dust mask is not a vapour mask

Im using an acid called phos acid is that good enough or should i get the hydro acid?Also how much PSI should i use on the bricks? I have 4000 but scared i will blow the brick or mortar

That mask wont protect you from the fumes. Please get yourself an appropriate mask if you do not want to die early due to failed lungs (due to diseases like asthma, COPD, lung cancer etc)

hate those masks when they fog up your glasses. you're protected but cant see SHIT!

As a "how to" video this sucks I accept a mask is better than nothing, but the clue is in the name... DUST mask! You need an inorganic gas (fumes) filter in a respirator mask. When using the high pressure jet do not stand square on to the brickwork as that is simply standing in the spray pattern, so the acid is landing on you. If you must stand square on then use a full face visor and keep your hood on. Better to use the jet pointed obliquely away from you.

Never use the pressure washer, it's damage bricks.
