Why Does Your Pool Surface Keep Getting Rough? Here’s The Real Problem

Key Takeaways

• It’s important to maintain balanced pool water chemistry to help avoid rough surfaces. pH, alkalinity, and calcium hardness should be regularly and accurately tested, keeping those levels in line with recommended standards.

• Pool mineral deposits, like calcium scaling, are one of the main contributors to a pool surface becoming rough. Having a routine cleaning schedule and using the correct descaling agents can help keep these calcium deposits under control.

• Environmental stressors, including UV exposure and thermal cycling, contribute to the degradation of the pool plaster surface. Limit UV damage by investing in protective measures, like pool covers, to shield your pool from intense UV rays when not in use.

• Proper installation techniques and smooth pool surfaces go hand in hand. Hold your contractors accountable for the industry’s best practices, and have the pool inspected after installation to catch any deficiencies.

• Rough surfaces are often seen as a sign of poor maintenance or cleaning practices. Stop using harsh chemicals and adopt the best cleaning methods to help maintain your pool’s surface.

• Resurfacing or performing spot repairs on rough surfaces as soon as they appear will make your pool last longer and look better. Always work with the right professionals, like Clear Swim Pool Care, to find a customized solution that best serves your needs.

In most cases, surface roughness is caused by wear and tear on the plaster or finish. This is even more true the older your pool is or the more often it gets used. Leaving your pool surface uncleaned on a daily basis or putting off periodic resurfacing cycles only exacerbates the issue.

By addressing the root cause, you can make your pool surface look its best, ensuring a more pleasurable swimming experience.

What Causes Rough Pool Surfaces?

A rough pool surface can be caused by several factors, including common pool plastering problems and improper regular pool maintenance, which are usually intertwined.

1. Water Chemistry Imbalance Effects

Unbalanced water chemistry is one of the biggest causes of roughness. When the pH is too low, acidic water can damage pool plaster and lead to pitting and a rough surface finish. Incorrect alkalinity weakens the plaster, leading to breakdown.

Excessive chlorine use can compromise the surface, making it less durable. Consistent water testing will help identify these chemical imbalances early to avoid long-term damage. For instance, maintaining pH levels between 7.4 and 7.6 and alkalinity levels between 80 and 120 ppm can protect the plaster finish.

2. Accumulation Of Mineral Deposit

When water is too hard, calcium deposits are another contributor to rough patches on pool surfaces. Efflorescence, a salt deposit problem, further complicates the situation, especially on weir walls.

If you notice visible white scaling or rough textures, that’s a buildup of minerals that may need serious cleaning. A regular maintenance routine that uses descaling agents will help remove these deposits, preventing a hard finish on your pool surface.

3. Material-Specific Reactions

Materials such as plaster and concrete will respond differently to moisture and temperature variations. Curling, in which concrete edges curl up, is a common concern from exposure to the environment.

Some materials are more susceptible to wear when exposed to extreme conditions, so material selection is extremely important. Opting for durable materials designed for the specific environment of the pool can reduce these vulnerabilities.

4. UV Exposure And Temperature Impact

Prolonged UV exposure weakens swimming pool plaster, while constant temperature fluctuations put significant stress on the plaster surface. Implementing protective measures, such as using pool covers and conducting regular pool maintenance inspections, can effectively reduce UV damage and help maintain surface integrity.

Common Concrete Pool Problems

Despite being a long-lasting and highly customizable option, concrete pools frequently face common pool plastering problems and structural issues that jeopardize the pool’s integrity. Understanding these pool issues ensures proper regular pool maintenance and long-term usability.

Excessively Rough Surface Issues

A rough pool surface can irritate swimmers’ feet and calves, causing scrapes, cuts, and bruises. Torn bathing suits or a scratched torso are signs that the plaster surface is deteriorating.

Severe roughness is usually caused by improper plaster application, chemical imbalances, or the age of materials. This increases wear and decreases swimmer comfort. Fixing rough surfaces requires sanding down the area, resurfacing, or replastering, with costs ranging in the thousands of dollars.

Brushing regularly and keeping your pH levels in check (7.2–7.6) can help avoid this problem. Clear Swim Pool Care offers professional services to keep your pool in top condition.

Structural Crack Identification

When cracks develop and threaten structural integrity, they require immediate attention and repair. Unlike cosmetic cracks, structural cracks are often wider and go deeper into the pool substrate, potentially leading to significant water loss or dislocated tiles.

Shifting soil or improperly poured concrete may cause this. Weekly inspections are essential to spot horizontal and vertical cracking early. Repair costs vary but can be more than a thousand dollars. Early detection is key to preventing costly renovations.

Plumbing Leak Detection

Plumbing leaks cause an unsightly loss of water that seeps into your pool’s surface, raising repair costs significantly. Lowered water levels or marshy grounds around the pool can be signs of leaks.

Periodic inspections, such as pressure testing, can catch issues before they become major headaches. If left untreated, leaking can lead to calcium buildup, deterioration of plaster, and ultimately, structural compromise.

Shifting Concrete Patio Issues

Shifting patios affect both aesthetics and pool stability. Movement is generally due to soil conditions or shoddy building practices. Keeping an eye out for rough patches and addressing them quickly helps maintain your backyard paradise.

Allowing these shifts to go unchecked can result in extensive and expensive repairs.

Diving Deeper Into Pool Plaster Issues

Pool plaster, a widely chosen and cost-effective surface for concrete pools, often faces durability challenges that can lead to roughness and deterioration over time. Regular pool maintenance routines are essential for identifying stains and addressing common pool plastering problems.

Understanding Crazing

Crazing introduces a spider web pattern of small cracks on the pool plaster. This is usually due to poor drying practices or environmental stress. Even shallow cracks can affect the pool’s smoothness.

Controlling curing conditions and maintaining stable water chemistry can reduce this risk.

Etching And Scaling Differences

Etching erodes the surface due to aggressive water chemistry, while scaling causes white calcium deposits. Both result in a rough pool surface.

Daily brushing and weekly balancing of water chemistry can extend the plaster’s life. Acid washing can fix some of these issues, with costs around $450.

Delamination Explained

Delamination happens when the plaster pulls away from the Gunite underneath, risking structural integrity. The first signs are patches that peel or bubble up.

Bonded plaster resists delamination better than multiple plaster layers. Repairs usually involve chipping out compromised sections for a seamless finish.

Fading Of Plaster

Chalky plaster, sometimes from too much exposure to UV light or chlorine bleaching the surface, can cause the pool to look drab. Bromine sanitizers, having a mitigated bleaching effect, present a relatively attractive alternative.

Restoring that color may require refinishing, starting at $10,000+.

Stains On Pool Plaster

Often, plaster stains are a result of metal deposits, algae, or minerals. Through proper cleaning techniques, whether through scrubbing or with controlled chemical treatments, stains can be removed without damaging the plaster.

A proactive approach, starting with the installation of balanced water chemistry, helps curb future discoloration.

How To Identify The Real Problem

Preventing your pool surface from becoming rough starts with identifying the real problem. A chalky plaster finish might indicate anything from water chemistry imbalances to builder negligence.

Solutions For Rough Pool Surfaces

The best way to deal with rough pool surfaces is through a mix of diligent regular pool maintenance, proactive pool plaster repair, and smart choices. Here’s how pool owners can embrace a few different DIY solutions to achieve a smoother surface and a longer-lasting swimming pool.

Resurfacing And Repair Techniques

Resurfacing is the only practical way to address extensive roughness. Popular ways to combat this range from plastering to pebble finishes and quartz-based coatings.

The cheapest finish is plastering, but it will need to be replastered every 10–15 years at a cost of about $12,000–$20,000. Although pebble finishes offer a more durable and slip-resistant surface, the initial investment is more costly.

Quartz-based coatings provide a good cost-to-durability value, creating a very smooth texture that will withstand etching and abrasions. Clear Swim Pool Care gives you peace of mind with responsive application, including critical angle spraying for even coverage and reduced overspray/rebound.

Acid Washing Explained

Acid washing is a technique that can help to restore an old pool plaster finish by removing stubborn stains and scaling. First, drain the pool completely, then apply a diluted acid solution evenly using protective tools.

We recommend scrubbing the affected areas lightly to minimize any potential harm. This technique adds texture and depth but can’t be done too frequently because doing so continues to thin the plaster.

Be sure to wear proper protective equipment and neutralize chemicals before disposal to protect your safety and their safety.

Spot Repair Options

For roughness that is localized, spot repairs are economically and logistically favorable. Products such as patching concrete work great for tiny cracks or chips.

A surface prep checklist would list items such as trowels, sponges, and safety goggles. Although not as aesthetically pleasing due to a lack of appearance uniformity, spot repairs are quicker and less invasive than a full resurfacing.

Complete Resurfacing Benefits

It is much more durable and beautiful to completely resurface your pool. It avoids leaks, keeps a uniform texture, and improves the property’s overall value.

When it comes to commercial solutions and professionalism, Clear Swim Pool Care guarantees bolstered long-term results through expert services.

Maintenance And Prevention Strategies

Maintaining a smooth pool surface begins with a proactive routine. Following a detailed maintenance program developed for your pool’s individual needs will keep surfaces smooth and your pool durable for many years. By chunking all of these upkeep tasks into a daily/weekly/monthly routine, it doesn’t feel as all-consuming but is still very impactful.

Consistent maintenance ensures your swimming pool is both an attractive and safe amenity. This support is vital for the 36% of children and teenagers, as well as 15% of adults, who regularly take the plunge year-round.

Regular Water Testing Importance

Regular water testing helps to catch chemical imbalances before they cause aggressive surfaces. Provide a schedule to test pH, alkalinity, and chlorine at least once a week, maintaining free chlorine levels between 1-3 ppm.

Recording outcomes in a journal allows you to detect trends and make data-backed changes. Seasonal changes in both temperature and demand further complicate factors that require consistent testing to help keep water chemistry in balance.

Balancing Chemicals Correctly

Restorative maintenance brings back quality. Balanced chemistry restores surface appearance and helps avoid damage. Control pH, calcium hardness, and chlorine levels, making adjustments as necessary.

Creating scale: The wrong water chemistry, like elevated calcium levels, can lead to scaling, while incorrect pH levels can erode pool plaster. Develop a checklist to track these variables through regular preventive maintenance.

Proper Cleaning Methods

Keeping pavements clean deters the accumulation of harmful debris that can degrade surfaces over time. Vacuum walls and floors at least once a week, focusing on corners and stair steps.

Only use gentle, pool-safe products that won’t harm plaster. Be sure to clean or backwash your filters regularly to keep your water clear and your system operating efficiently.

Protecting Against UV Damage

In addition, prolonged UV exposure can lead to plaster deterioration. Use pool covers or pool shades to protect your pool from the sun rays.

Routine preventive maintenance inspections (PMIs) will help identify the initial signs of UV wear.

Monitoring Calcium Levels

Calcium content significantly impacts the surface material's texture. Regular pool maintenance routines, including testing for scaling and addressing any imbalances, are essential to preserve the smoothness and appearance of swimming pool plaster.

Key Material Insights For Pool Surfaces

The surface quality of a pool largely depends on the chosen materials during construction or resurfacing. Understanding concrete pool information and the nuances of swimming pool plaster can significantly impact the durability and appearance of the pool. With the right material choices, you can achieve an enduring, silky-smooth surface that requires less regular pool maintenance.

Plaster Composition And Durability

Plaster, the original material of choice, which the National Plasterers Council likes to refer to as a “semi-permeable membrane,” is still commonly used. It is made up mostly of cement, water, and marble dust or silica sand. That curing process is essential.

Customarily, plaster requires underwater curing because if it dries too quickly in the air, you will get shrink cracks and surface defects. You can usually recoat over the existing plaster with new plaster—a 3/8-inch layer. This approach provides you with a smooth new surface that completely camouflages all the chips and cracks.

Roughness is created over time when an inferior mix is installed and/or proper maintenance is sidelined. Please note that factors such as water chemistry, cold chemistry, and the appropriate, skillful application play a significant role in the lifespan of plaster surfaces.

Final Remarks

Keeping your pool surface smooth takes effort, but it pays off with a better swimming experience and less long-term stress. Pool owners often mistakenly believe that rough surfaces are something that happened overnight. They accumulate due to a lack of maintenance, improper water balance, or just time taking its toll on older surfaces.

Once you know what’s going on, you can take immediate steps to prevent the issue from escalating into something worse. Whether you’re patching small areas, resurfacing, or replacing with different materials, finding the right repair method goes a long way to solving your real problem.

Keeping regular maintenance, such as balancing pH levels and brushing surfaces, will prevent these problems, saving you time and money in the long run. If this seems like a daunting task, don’t worry—hiring a professional is an excellent investment.

A rough, dingy pool is not a pleasant experience—both in aesthetic and functional terms. Treat it with the same care it deserves, and it’ll provide years of unforgettable fun.
