This forum has been a big help to me in the past, so let’s try it again. I am having some strong concerns about my contractors treatment of my new pavers. 1900 sq/ft, Calstone tumbled pavers. They looked beautiful when installed. To better protect my investment, I asked him to seal the pavers. He told me that only about 10% of his paver clients asked for this, but no problem. Worker shows up speaks little English and is mixing Muriatic acid and water in a bucket and then pouring it over the pavers and pushing it around with a push broom. Acid was not measured, just a few glugs into a bucket then pour. Pavers and sand bubbled as would be expected. Treated area flooded with water to rinse prior to doing the next area. This left some pavers looking really “clean” and some cloudy, so we do this again 2 more times until all look about the same. Contractor tells me that this is necessary as the sealer brings out the “efflouresence” in the pavers. Pavers now sealed about a week and the edges are beginning to turn white from “efflouresence” and the pavers are getting splotchy looking. I don’t want any more acid, and I’m not shure my contractor knows what he is doing.
I have two basic questions. For those who do pavers, does this sound like proper procedure? Should I ask other paver contractors to come by and comment?
I am loosing faith in my contractor, I mean if he can’t get it right from the start, how can I trust him to fix the problem.
