Preparing to Fix the Problem

• Inspect the area thoroughly with a flashlight and, if possible, a moisture meter. Search for concealed cracks or dampness.
  
  
• Clean the wall with a gentle detergent and water to clear dirt, algae, or mineral deposits. A brush or pressure washer can aid, but ensure you don't harm the wall.
  
  
• Allow the wall to dry fully before beginning repairs. Moisture trapped under a patch can lead to mold or future leaks.
  
  

Step‑by‑Step Fixes for Each Issue

Small Hairline Cracks

1. Clean the crack with a wire brush and remove any loose debris.
   
2. Apply a high‑strength, two‑component epoxy patching compound. Blend as per the manufacturer’s guidelines and fill the crack entirely.
   
3. Use a putty knife to smooth the surface, then cure for the recommended time.
   
4. Seal with a waterproof sealant or pool‑grade paint to blend with the surrounding wall.
   
   

Water Seepage / Blue Spots

1. Use a wet‑dry vacuum or a shop vac to remove all moisture from the affected area.
   
2. Use a water‑resistant, high‑silicone sealant on the spot. Silicones are flexible, allowing for minor pool wall movements.
   
3. For larger leaks, consider a repair kit that includes a primer, a patching compound, and a topcoat.
   
4. Re‑seal nearby grout lines using a dedicated pool‑grade grout sealant to block further seepage.
   
   

Scaling / Mineral Buildup

1. Use a scraper or a non‑abrasive pad to remove the scale.
   
2. Rinse the area thoroughly with fresh water.
   
3. Apply a commercial pool scale remover or a dilute acid solution (like vinegar or a specialized product) to dissolve remaining deposits.
   
4. Rinse again, followed by a protective coating to help prevent future buildup.
   
   

Corrosion of Metal Fittings

1. Remove any rust or corrosion with a wire brush or a rust remover.
   
2. Wash the fittings with a mild detergent.
   
3. Apply a high‑quality, pool‑grade paint for stainless steel or brass to restore protection.
   
4. Ensure the paint cures fully before re‑installing the fitting.
   
   

Crumbling Plaster

1. Take out loose plaster using a pry bar or sledgehammer, taking care not to harm the concrete.
   
2. Clean the underlying surface and let it dry.
   
3. Apply a primer specifically for pool plaster.
   
4. Mix and spread a new plaster layer, matching the existing texture as closely as possible.
   
5. Seal with a compatible sealant for the new plaster.
   
   

Safety Tips for DIY Pool Repairs

• Use protective gear—gloves, goggles, and a mask—when working with chemicals or dust.
  
• Keep kids and pets away from the repair area until all chemicals have set.
  
• Do not mix different sealants or epoxy products unless manufacturers confirm they’re compatible.
  
• Follow all local building codes and, if unsure, consult a professional for a quick check.
  
  

When to Call a Professional

A professional can evaluate the issue and deliver a lasting solution that may involve more invasive repairs or materials.
