Pool Plaster Repair Is Likely Necessary As Your Pool Ages

If you are the owner of a gunite or concrete pool, you will likely need to perform a pool plaster repair at some point during the lifespan of your pool. Cracking, hollow spots, and chipping are natural occurrences and are to be expected over time.

What Is Pool Plaster?

Plaster is not a part of the pool’s structure, but is actually a waterproofing membrane. It is placed over the porous concrete pool shell. A dense mortar layer, it reduces water permeability.

Pool Plaster Repair

Fortunately, you can perform most pool plaster repairs to fix small cracks and chips. There a few things to look for when identifying how to repair your pool plaster.

Crazing is a network of spider cracks that appear due to the contraction of the surface layer of concrete. These will typically appear shortly after new concrete has been finished.

Non-structural cracks refer to any cracks in the plaster itself, and not in the concrete shell. Any cracks that develop later in the life of the plaster are typically the result of a crack in the concrete shell layer, and is almost certainly the result of a delaminated area of plaster.

Structural cracks will present themselves in the same manner as non-structural cracks. However, these will likely be bigger, wider, and deeper than non-structural cracks.

Delamination typically occurs during the process of bonding the plaster to the concrete.

Full Replacement

As your pool ages, and if you do not properly fix minor pool plaster problems, you may need to perform a complete replaster. This can be done for aesthetic reasons or for practical reasons. The new coating can be placed over the old plaster. It is best that you hire a pool servicing company to help you with your full replaster, which can often require a full drain of your pool. The replaster can typically be completed in a few hours by a team of professionals.
