Pool resurfacing or replastering should be done every 10 years. This is based on the surface lifespans of cement and pool plaster material. But constant use, chemical exposure, and climate changes can damage the pool plaster. That said, you should consider resurfacing your pool every 3 to 7 years.
It varies depending on the type of pool, with plaster or cement pools needing to be resurfaced every 3-7 years while fiberglass pools can sometimes go as long as 15-30 years.
If you don't resurface the pool, which is necessary because it is always exposed to weather, cracks and an unevenness in the pool surface will occur and this could lead to algae stains, water leaking and injuries from the uneven surface.
On Average, Replastering is Every 10 Years
So how often do you need to replaster a pool? The short answer is about every 10 years. However, it's important to consider the factors mentioned above, as they are typical signs that your pool needs to be replastered.
Quartz pool finishes are a combination of a quartz aggregate and polymer-modified cement – technically making it a kind of plaster surface. Quartz surfaces are in ways the best of plaster and pebble finishes. SwimmingPool.com said quartz finishes typically last between seven and 12 years.
Pool mottling, the variations in the color of cement or pool plaster, is a common concern among pool owners and pool remodelers alike. Ranging from unnoticeable to severe, the mottling of pool finishes like quartz and plaster, as well as cement decks, is unpredictable and can happen to any pool.
Swimming pool resurfacing costs vary between $1,000 and $30,000. DIYing your swimming pool repainting project can cost as little as $1,500. Expect to pay about $6,500 per 1,000 square feet for high-end options.
Cracks In the Pool's Surface
At the end of the day, the most important reason to resurface your pool is to protect your pool from structural damage. Large cracks or spider web cracks occur due to the natural process of the cement hydrating.
It will chip and wear away more easily, and when it does, you will need to repair it. If there's a reason to use paint over plaster, it's that the application process really is a lot easier. While you could paint on your own, replastering is something that only the most industrious homeowners take on.
The plaster material cures under water in about 7-10 days. But this doesn't mean you have to wait that long. Once the pool is filled and clean, you can go in for a swim.
Chlorine/non-chlorine chemicals – When adding chlorine or non-chlorine chemicals to “shock” your pool after a fill-up, wait about 24 hours or until levels are approximately 5 ppm. If you'll only be adding liquid chlorine, it's generally safe to swim after about 4 hours or until levels are 5 ppm or lower.
Diamond Brite is an exposed aggregate pool finish made from a blend of natural quartz aggregate, cement modified with polymers and fade-resistant color-quartz, which is available in a large number of stunning varieties.
So, when a client requests a new pool surface, the pool remodeling industry refers to that as pool resurfacing or replastering. Since the project focuses on the interior surface — the walls and floor of the pool — price can vary.
The sanding process will prepare it for a good epoxy coating bond. Once it's been sanded properly, wash the pool as previously detailed—acid washing isn't necessary. Allow to dry completely and you're ready to resurface your pool!
Things You'll Need
Gunite swimming pools can be particularly susceptible to surface staining and damage. A professional refinishing and painting process can go a long way in preventing these issues from becoming severe and unsightly.
To paint the pool, you'll need to degrease the surface with TSP, then acid etch the plaster, followed by another washing and scrubbing with TSP. For acrylic pool paints, the pool can be painted damp, but for epoxy paints (the longest lasting pool paint), you'll need to let the pool air dry for 3-5 days before painting.
The installation of a new plaster surface causes fluctuations in the water chemistry. The alkalinity, pH and calcium levels will rise while the surface is curing. The new plaster is susceptible to staining and discoloration during the first four weeks.
Etching happens when lines and dents are literally carved into your pool plaster over time. This is caused by improperly balanced pool chemistry, particularly low pH, alkalinity, or calcium, and it's one of the reasons why we emphasize the importance of taking care of your pool correctly.
One major thing to remember is that pool plaster can change colors or overall look as it sets and cures. Plaster is hand applied, so it is normal to expect slightly uneven areas, and the color will not be 100% uniform throughout the pool. Also, as the plaster cures, the appearance will change slightly.
Gunite pools have been around since the '60s and are the most durable pool finish due to being made from concrete. The pool's structure consists of a steel rebar frame coated with a mix of cement, white sand or marble aggregate, and water.
Proper maintenance can lengthen life
Once again, quartz can last longer than the average if water chemistry is properly maintained. Pebble finishes, combined with modified cement, last 15+ years. This is the most durable cement based pool finish.
I. If the pool ever needs to be drained to replace the water or to maintain the plaster, it should never be left empty for more than eight to ten days at the most. More than this may cause the plaster to dry out and crack. Keep your pool full for best results.
