Replaster Methods

ALL REPLASTER METHODS ARE NOT EQUAL.

When preparing to have your pool replastered all Homeowners should make sure they specifically ask their Contractor how long the plaster finish they are installing will be guaranteed to adhere to the substrate before signing a contract.  G&B Tile and Plaster (G&B) guarantees our process longer than any competitor.  It is detailed in our 3 year warranty against bond failure.

There are several methods of replastering acceptable, according to the National Plasterers Council Technical Manual.  The most common method in our market (DFW) is the use of bond coat to adhere the new plaster to the old plaster.   The problem with this common method is the type of bond coats used and the extent at which they are used.   At G&B we don’t use the most common method, we use the best method.

Replastering a pool does not mean to layer plaster layer upon plaster layer.  Any plaster company can replaster a pool; however, if you hire a company that replasters your pool without stripping outer layer(s) of plaster prior to the replaster process, your pool will not be properly replastered.  If a pool that is going to be replastered has more than one layer of plaster, the outer layers must be removed.  Depending on how many times a pool has already been replastered extra charges may be incurred to remove layers of plaster to find a sound surface to perform the prep process.  Anything less than this is a bad practice that can lead to failure in your investment before you would expect. 

There are two main types of bond coats used in the pool industry when replastering a pool:

• Manufactured bond coats (such as Multicoat) designed for underwater use, are acceptable if the pool has never been replastered and the existing plaster is solid.  Manufactured bond coats should not be used over multiple layers of plaster without first stripping the layers of plaster off the pool to find a solid, non-hollow surface.
• “Glue bond coats” or home brews are used by several companies in DFW.  This is simply glue with other components added to it, creating a product that has not been designed for underwater use, but rather used by the company to save expenses.  Allowing a home brew bond coat to be used on your pool is a bad practice.  When having your pool replasted, a pool company should be able to tell you exactly what type of bond coat they will be using on your pool…if the company can’t or won’t tell you, call G&B Tile and Plaster.
