waterproof plaster for swimming pool

Some pools might need a chemical treatment or a chemical wash to clean and prep the surface. Use a sandblaster or chisel the underlying concrete to ensure the new material holds well. Focus on a tiny area of the pool at a time. This process can take up to three days, depending on the size of your pool.

Although there are products sold for DIY replastering (www.sider-crete.com is one vendor that sells a kit that covers 60 square feet for $130), most DIY pool plaster products are meant for repairing only small areas. Based on a national average computed by homeadvisor.com, a professional replastering job will cost about $5/sq.ft. for plain plaster, and nearly double that for a polished exposed aggregate plaster.

Gelcoat pool application is a factory process so it can't be easily replicated in your yard. Instead, there are replacement coatings--thermoplastic polymers that are used to resurface fiberglass. Before the new coating can apply, the pool must first be completely drain and sanded.
