Had new pavers installed wish to seal them wondering before sealing how strong of a muric acid wash should I clean them with like maybe 20 to 1 ratio. Have cobble stone affect with limestone white marks on some of them whick would like to rid off if I can. Live in northern Florida

Never apply any type of sealer in new installation, wait about 60 days before applying sealer because one has to let the efflorescence (which is the whitish, old stain you see on pavers after a while) accumulate in order for you to seal. If applied prior to 60 days, efflorescence will gather and be caught under the sealer formed barrier and would have to be stripped. Make sure you remove all stains before sealling and wait about 24 hrs for pavers to dry completely in order for sealing
