Please help! - Cutting dust + pavers = dull & muted :(

[suzymomma]

greetings!
here's the deal...I had my pool deck covered with interlocking concrete pavers. The area is surrounded by a high privacy wall. The dust fom cutting pavers and flagstone didn't blow away w/the wind; because of the wall, it coated everything. The dust was not removed and was allowed to settle on and coat the pavers and everthing else with in the wall! It also rained on them when they were coated w/ the cutting dust. The pavers nearest to the water were special/treated pavers, incase the pools are salt water pools. All of the regular pavers now look muted and dull. The landscape company tried to tell me this is effloresenc...but we had 3 walkways, 3 patios, and a meditaion garden done in the pavers as well. Only areas that were exposed to excessive cutting dust look dull, muted, faded if you will. I have now read on line where this is a problem...how do we get rid of the white-ish haze on the pool deck pavers? The guy said he used muratic acid and a brush to "clean " them and that's about all he can be done. It didn't change their appearance! I need to know what specifically do you call this type of problem IE "cutting dust that clouds the pavers" AND MOST importantly how is it fixed. Belgard interlocking concrete pavers were used.
Thank you for any and all help/info you maybe able to offer me concerning this problem!

Hi suzymomma the best course of action would of been for your contractor to use a block splitter, or if he had to use a power saw, he should of attached a water suppressor with a bund to catch the grout. i cant see why he used acid cleaner on newly laid block work. maybe the acid was to strong a mix i would of thought a light jet wash to be sufficient.

i notice you are usa based
efflorescence is quite common with concrete products in wet areas
dont know why he used muriatic acid though
a picture would be handy

As LLL says a photo would be good, also I know quite a few professinol pressure washing companies over there that might be able to help let me know and I'll check as to how I know in AZ.
