Quality parapet rebuilds include the use of factory-made basecoats.
Many contractors make the mistake of thinking that the parapets are ok prior to a restucco, and that they will not need a basecoat or new reinforcing. When the parapets deteriorate not long afterwards, after the warranty runs out, it ruins the job, usually requiring another restucco.
There are many ways of doing a parapet rebuild, and there is no one "right way." However, there are better and worse ways. Here at Stucco Seal we've perfected what we think are some very good ways, which vary from house to house.
In our opinion all good parapet rebuilds include the use of factory-made basecoats such as El Rey Wallease base, and fiberglass mesh like El Rey Krakmaster mesh.
