Pool Deck Acid Stain

[marvello]

I am not sure the brand of our pool deck but is is similar to a cool deck. Muriatic acid spilled on the deck during the day with temperatures close to 100 degrees. when I finally got it off the deck it had removed the coloring. Is there anyway of fixing this problem. It has spots that look bleached.

Hi Marvello, Welcome! :)

First I would neutralize the area with some ammonia & water (1:3 - 1:4).

I recommend trying a couple different enhancers. Medium darkening with Stone Tech Enhancer Pro. Deep darkening with Aqua Mix Enrich n Seal.
