How Should I Care for My New Plaster Pool? Everything You Need to Know to Protect Your New Plaster Pool During Its Most Critical Phase
Expert Tips for the First 30 Days and Beyond—From Curing to Chemistry and Long-Term Care

At Distinctive Swimming Pools, we get a lot of questions about how to properly maintain a new plaster pool. It’s an exciting time—but it's also crucial to follow the right steps to make sure your investment lasts for years to come. Here’s what you need to know during the first 30 days and the first season after plastering.
Q: Why is the first 30 days of plaster pool maintenance so important?
A: Great question. The first 30 days are absolutely critical because your plaster is still curing—that means it’s hardening and developing strength. Think of it like concrete work on a massive scale—even the concrete in Hoover Dam is still curing!
While your pool isn’t nearly that size, the same principle applies. The plaster continues to cure below the surface for weeks after it's applied. During this period, the surface is more susceptible to staining, etching, or scaling if not cared for correctly.
Q: What do I need to do during the curing period?
A: Here’s a quick checklist:
- Brush the pool 2–3 times a day for the first 2 weeks. This removes plaster dust and helps the surface cure evenly.
- Do not use a pool heater for the first 30 days.
- Avoid swimming for the first 3–7 days (your pool pro will give you exact timing).
- Watch your water chemistry closely. Imbalanced water can permanently damage the new plaster.
Q: What’s so important about water chemistry?
A: Your water chemistry plays a huge role in how well the plaster cures and lasts. During the initial 30-day startup:
- pH, alkalinity, and calcium hardness need to be tested and adjusted frequently.
- The water should be neither too aggressive (which can etch the plaster) nor too scaling (which can cause calcium buildup).
We recommend professional water testing 2–3 times a week during the first month to keep everything in check.
Q: What about maintenance during the first season?
A: After the initial 30-day curing period, your pool is more stable, but it still needs special attention for the rest of the first season:
- Continue regular brushing at least weekly.
- Stick to a consistent water testing schedule. Keep pH, chlorine, and calcium in recommended ranges.
- Be cautious with pool chemicals—no dumping them directly into the pool. Pre-dilute when possible and always add chemicals slowly.
- Schedule a professional inspection mid-season to make sure everything is progressing well.
Q: Can I use my pool like normal after the first month?
A: Mostly, yes! After 30 days, you can enjoy your pool like normal, but keep in mind that new plaster can take up to a full year to fully cure. That means staying on top of chemistry and brushing is still important. Think of it as breaking in a new car—you’ve got to treat it right in the beginning to get the best performance down the road.
