how to refinish a pool


Refinishing a pool involves restoring the interior surface of the pool to its original condition or giving it a new finish. This process can help improve the aesthetics and functionality of the pool. Here are the general steps to refinish a pool:

Materials and Tools You May Need:

  • Pool resurfacing materials (such as plaster, pebble, or tiles)
  • Pool surface preparation chemicals
  • Pressure washer or sandblasting equipment
  • Trowels and plastering tools
  • Safety equipment (goggles, gloves, respirator)
  • Water hose
  • Pool pump (for refilling)
  • Pool brush and vacuum
  • pH test kit and pool chemicals
  • Sealer or waterproofing compound (optional)
  • Pool paint (if applicable)

Steps to Refinish a Pool:

  1. Drain the Pool:
    • Start by draining the pool completely. Ensure that the water is properly disposed of according to local regulations.
  2. Prepare the Pool Surface:
    • Use a pressure washer or sandblasting equipment to remove the old pool finish. This step is critical to ensure good adhesion of the new surface. Remove any loose or damaged material.
  3. Repair Cracks and Damage:
    • Inspect the pool for cracks and damage. Repair any cracks or imperfections with a suitable pool repair compound or patching material.
  4. Prepare the Pool Shell:
    • Clean the pool shell thoroughly by scrubbing it with a pool brush and vacuuming up any debris or dust. Ensure the surface is free from contaminants.
  5. Apply a Bonding Agent (if necessary):
    • If you are applying a new surface finish like plaster, apply a bonding agent to the pool shell. Follow the manufacturer’s instructions for the specific product you’re using.
  6. Apply the New Pool Finish:
    • Depending on your choice of finish (plaster, pebble, tiles, etc.), apply it according to the manufacturer’s guidelines. Plaster, for example, is often mixed with water and applied with trowels in multiple layers. Pebble finishes are spread evenly over the pool surface.
  7. Smooth and Level the Surface:
    • Work the new finish material to create a smooth and level surface. Ensure there are no air pockets or uneven areas. Trowel the surface as needed to achieve the desired texture.
  8. Cure and Set:
    • Allow the new finish to cure and set for the recommended time period, which can vary depending on the material used. During this time, keep the pool area moist to prevent cracking.
  9. Fill the Pool:
    • Refill the pool with water using a garden hose or pool pump. Monitor the water level closely to prevent overfilling.
  10. Balance Water Chemistry:
    • Test the pool water’s pH and chemical balance, adjusting it as needed to ensure it falls within the recommended range. Proper water chemistry helps maintain the new pool finish.
  11. Start the Pool System:
    • Turn on the pool pump and filtration system to circulate the water and maintain its cleanliness.
  12. Inspect and Maintain:
    • Regularly inspect the pool surface for any signs of damage or deterioration. Perform routine maintenance, such as brushing and vacuuming, to keep the pool clean.
  13. Apply a Sealer (optional):
    • Depending on the type of finish used, you may choose to apply a sealer or waterproofing compound to protect and enhance the durability of the pool surface. Follow the product’s instructions for application.
  14. Consider Pool Paint (if applicable):
    • If you choose to use pool paint, follow the manufacturer’s instructions for surface preparation and painting. Pool paint is often used for concrete or gunite pools.

Remember that refinishing a pool is a complex and labor-intensive process. Depending on the size of your pool and the chosen finish, it may be a job best suited for experienced professionals. Additionally, regular pool maintenance is essential to prolong the life and appearance of the new finish.
