How to Gunite a Pool

By David Kim Apr 28, 2023

Guniting is a popular method for constructing swimming pools due to its ability to create a water-resistant pool rapidly and affordably, without requiring expensive excavation. This technique involves applying a mixture of concrete and sand to an existing form or pool shell using a specialized guniting machine. This page will provide a comprehensive guide to guniting a pool, from preparation to the finished product.

Prep Stage

The following supplies must be available before you start gunitie a pool:

  • Concrete mix
  • Sand
  • Hose
  • Gunite hose
  • Gunite nozzle
  • Gunite machine
  • Protective eyewear
  • Long-handled shovel
  • Trowel
  • Finishing trowel

Prior to applying the gunite, you must prepare the pool. In addition to making sure the pool is level and the walls are securely fastened, this also entails cleaning the pool of any dirt and debris. The gunite process can get started once the pool has been readied.

Step 1: Excavate the Pool

Excavating the area where the pool will be located is the first step in building a gunite pool. It should be level, somewhat larger than the size of the pool, and have straight walls.

Step 2: Install the Rebar

The rebar installation process is what comes next when the excavation is complete. The pool shell is strengthened and kept from cracking by this reinforcement. Installing the rebar requires adhering to the pool design criteria.

Step 3. Install Pool Forms

Building the pool forms, which are temporary barriers that hold the gunite in place until it solidifies, is the next step. The forms must precisely match the pool’s dimensions and shape.

Step 4: Use gnite

Applying the gunite mixture is the next stage in creating a gunite pool. A special machine is used to spray the sand, cement, and water mixture over the rebar and pool forms. After that, the mixture is manually molded into the desired texture and shape.

Step 5: Finishing the Pool

Allow the gunite to cureThe gunite needs several days to cure after being applied. This is necessary for the gunite to harden and become more powerful. Gunite must be maintained moist during the curing process to avoid cracking.
