How to Select the Proper Plaster Finish for your Pool

Pool and spa owners have many beautiful swimming pool surface finish options available. From the simplicity of classic white plaster to the rainbow of multi-colored pebble finishes, the choices can be exciting. But with so many finish options available—exploring the specific benefits and drawbacks inherent in the various surface products are understandably daunting.

Select Your Surface Finish Carefully

Pool and spa finishes are unique in that they, unlike other masonry products, are constantly submerged in water. This obvious fact means that any pool finish will be exposed to varying water chemistry conditions over time, especially if the pool or spa is not maintained properly. Constant exposure to powerful chemicals creates an environment where mineral content of the surface and water are constantly interacting and could cause the plaster to change appearance slowly over time. In some extreme cases, without proper chemical monitoring, some surfaces will deteriorate which is why exploring all possible options and their strengths and weaknesses is advised.

While any of the products and surface options listed here can provide years of reliable performance and dazzling beauty, the key to enjoying them is to understand them and to keep your pool or spa well-maintained. Chemical balance is very important to the nurturing of your selected surface finish.


Standard White Plaster

This classic finish has been around as long as pools have been built. It is a popular choice because of its simple combination of white cement and marble aggregate. It is economical and gives your pool that classic look.


  • When filled with water, pools and spas surfaced in white plaster create a brilliant, clean, light blue appearance that is very smooth to the touch.
  • It is the most affordable pool finish product on the market today.
  • Reliable when properly maintained.


  • Classic white plaster is susceptible to all water conditions especially from attacks of improperly maintained or fluctuating chemical conditions.
  • During the life of the product expect it will change in appearance. The changes may be subtle or minor, perhaps slight shading or scaling, or far more dramatic in the form of pronounced staining, etching, or even cracking, in extreme cases.
  • It is a relatively "soft" finish compared to other options and more susceptible to the effects of water chemistry than some of the more durable products.
