D. Scrub using a wire brush to remove worn-out plaster, algae, and dirt from the area you’re going to fix.

Pool Crack Repair Using Underwater Epoxy Putty

An Epoxy underwater pool repair kit comes in 2 parts or bars, which need to be combined before it sets. The first bar (A) is the actual putty or the patching ingredient. The second bar (B) is the hardener that makes the bonding reaction a lot stronger.

1. Cut equal parts from each of the A and B Epoxy putty bars. You can use the ruler on the paper holder to guide you in cutting the exact equal amounts.

2. Mix equal amounts of A and B putty and mold them as one piece. Knead and roll the putty on a clean working surface or in your hands between 4 to 5 minutes.

The shape of your mold should match the crack or gouge you’re trying to fix.

Your mold should resemble a tube or a rope for cracks. Roll your putty into a ball if you want to fix a gouge or a chip.

3. Press the putty as far into the cracks or holes.

4. Use your fingers or a trowel to smooth the edges flat against the surface of the pool.

What are Common Pool Plaster Problems?

1.Pool Plaster Crazing

Small clustered cracks or craze cracks happen as your pool plaster shrinks. Plasters shrink when water is absorbed during the curing process. Crazing happens when there is too much shrinking of the pool plaster.

2.Pool Plaster Etching and Scaling

Spot etching is characterized by excessive roughness on the pool surface. Dents and lines are etched into the pool plaster over time. The common cause of etching is an improper balance of pool chemistry such as low:

  • pH
  • alkalinity or
  • calcium

This link explains the causes of pool leaks.

Pool plaster scaling is the result of high:

  • pH
  • alkalinity or
  • calcium

3.Pool Plaster Spalling

Spalling occurs if there was incorrect troweling done on your pool’s plaster. It’s either the improper timing of the troweling process or the plaster is over-troweled.

The result is the flaking or peeling of a thin layer of plaster, which is about 1/8th of an inch. Also, the addition of excess water while troweling can cause spalling.

4.Pool Plaster Delamination

Delamination is the separation of the new coat of plaster from the old layer beneath. Small pop-off spots the size of a quarter may not or show large bond failure. Yet, delaminations can go undetected for many years until the cracks appear and begin to flake off.

The common causes of plaster delamination are:

  •   Over-troweling
  • Thin plaster coating
  •  Too much cold or heat on the day of plastering
  •  Improper cleaning of the surface or
  • There was no application of the bond coat

5.Pool Plaster Fading

Constant exposure to sunlight and chlorine can cause your pool’s plaster to fade over time. You’ll notice a significant change in your pool’s plaster color after 8 to 12 years. Pool sanitizing products like chlorine and bromine can cause the plaster’s color to fade.

6. Pool Plaster Stains

Having pool plaster stains is inevitable. A majority of concrete pools will most likely develop stains over time. Organic and inorganic materials are the culprit to pool plaster stains.
