Brick work question


#1

I know there’s a ton of info here on acid washing etc. it’s actually something I’ve never done though. In this case, it’s only a small bit, so would pressure move it, or do I need acid?


#2

f9 efflo, NMD 80 or someone on here a couple of weeks ago had some good results with the Zep calcite remover


#3

Looks like eflo and ppl swear by f9. I have some but haven’t used it yet…lol


#4

I guess you posted this while I was typing…lol


#5

Great info guys, only we do t have either over here!

What’s the active ingredient?


#6

You should be able to get Zep at Lowes or Home Depot.


#7

Not sure they have those in Australia


#8

Can you order off Amazon


#9

Correct. None of those.

I heard muratic acid was the usual thing?


#10

Google the sds on on the zep and nmd 80


#11

Got it - thanks!


#12

You can use white distilled vinegar too which you should be able to get. But you’ll need to scrub a little


#13

Oh we have that! Ha ha. It’s only a small patch as you can see, but I wanted to go prepared if pressure doesn’t get it off :ok_hand:t2:


#14

Ahhh I found this…


#15

Pressure will get it off until it dries, lol
