"Project: Repair and partially replace stucco surface of small retaining wall. Phil met with me and we discussed how to treat a short retaining wall that was losing the stucco surface after about 4 years since it was originally plastered. The wall was alowing water seepage to come thru the concrete block and lifting the original stucco finish off. Phil suggested a repair , consisting of first scraping all loose stucco off the wall and then applying an adhesive type undercoat followed by a total restucco of the wall. It was done very professionally , minimal debris, 2-day process , and it looks great. Now I just have to see how it holds up over the next 4-5 years . Highly recommend PG Plastering."
