Re-marciting a pool involves resurfacing the interior of the pool with a new layer of marcite, which is a type of plaster commonly used for pool finishes. This process can help restore the pool’s appearance and waterproofing. Here are the general steps for re-marciting a pool:
Materials and Tools You’ll Need:
- Safety gear (goggles, gloves, mask)
- Pressure washer
- Pool pump and filter system
- Marcite mix
- Trowels and pool plaster tools
- Pool brush
- Water hose
- Acid wash solution (if needed)
- Pool plaster dye (optional)
- Pool finish sealer (optional)
- Drain the Pool:
- Completely drain the pool to expose the existing pool surface.
- Prepare the Surface:
- Use a pressure washer to clean the old marcite surface thoroughly. Remove any loose or damaged plaster, dirt, algae, or debris. If there are stubborn stains or scale deposits, you may need to use an acid wash solution to remove them. Rinse the pool surface after cleaning.
- Repair Cracks and Imperfections:
- Inspect the pool surface for cracks and imperfections. Repair any cracks with an appropriate pool repair compound, following the manufacturer’s instructions. Allow the repairs to dry and cure as needed.
- Prepare the Marcite Mix:
- Follow the manufacturer’s instructions to prepare the marcite mix. The mix typically includes a combination of white Portland cement and marble dust. You can add pool plaster dye to the mix if you desire a colored finish.
- Apply the Marcite:
- Start applying the marcite mix to the pool surface using trowels and pool plaster tools. Work in small sections, typically starting from the deep end and moving toward the shallow end. Ensure that the mix is spread evenly and smoothly. Maintain a consistent thickness as per the manufacturer’s recommendations.
- Trowel and Smooth:
- As you apply the marcite, trowel and smooth the surface to create a uniform and smooth finish. Keep the surface wet as you work to prevent premature drying.
- Curing and Watering:
- Allow the newly applied marcite to cure for several hours or as recommended by the manufacturer. During this time, keep the surface moist by misting it with water periodically.
- Final Troweling and Polishing:
- After the marcite has set but is still slightly damp, go over the surface with a pool trowel to achieve the desired texture and finish. You can also use a pool brush to smooth and finish the surface further.
- Fill the Pool:
- Once the marcite is fully cured, fill the pool with water using a hose. Ensure that the water level is balanced with the hydrostatic pressure in the ground.
- Chemical Treatment and Balancing:
- After filling the pool, balance the water chemistry by adding the necessary pool chemicals (e.g., pH adjusters, chlorine) to achieve proper water balance.
- Sealing (Optional):
- If desired, apply a pool finish sealer to protect and enhance the appearance of the marcite surface. Follow the manufacturer’s instructions for the sealer application.
- Startup and Maintenance:
- Start up your pool pump and filter system and maintain the pool according to standard pool maintenance practices.
Re-marciting a pool is a complex and labor-intensive process that requires careful attention to detail. It’s often best left to professionals experienced in pool resurfacing, as they have the necessary tools and expertise to ensure a high-quality finish. Additionally, following local regulations and safety guidelines is essential when working on a pool renovation project.
