If your pool surface is fading, chipping, or rough, painting a gunite pool might seem like a quick and affordable fix. It’s cheaper than resurfacing and can give your pool a clean look in just a few days.
At Ferrari Pools: Custom Outdoor Living, we’ve worked with gunite pools for decades and have seen pool paint work well in some cases and fall short in others.
This guide lays out the pros, cons, costs, and lifespan of pool paint so you can make the right call for your pool and your budget.
Key Takeaways
Painting a gunite pool is a quick, budget-friendly refresh, but it won’t last as long as plaster or aggregate finishes.
Proper prep and dry conditions make all the difference between a smooth coat and a peeling mess.
For lasting results and fewer headaches, talk to the pros at Ferrari Pools: Custom Outdoor Living before painting your pool.
What Is a Gunite Pool and Why Does It Matter for Painting?
A gunite pool is an inground swimming pool built with a dry concrete mix that’s sprayed over steel rebar and then finished on‑site. The structure is tougher and more permanent than many alternative surfaces.
Because of the way gunite is constructed, its pool surface behaves differently when you’re considering pool painting or other resurfacing. Unlike vinyl liner pools or fiberglass pools, you're dealing with concrete, rebar, and variable ground conditions. These all affect how paint adheres and lasts.
When it comes to resurfacing your gunite pool, you’ll typically weigh options like:
Painting the surface
Applying plaster
Going with a premium aggregate finish
Each has its own cost, durability, and maintenance profile because of the underlying gunite shell.
Can You Paint a Gunite Pool?
Yes, painting your pool is possible and can be practical in the right situation. If your gunite pool is in good condition and you want a quick, affordable refresh, pool paint can work well for the short term.
It’s a good option if you're prepping for resale, working within a tight budget, or just want to clean up the pool surface without committing to full resurfacing.
But painting isn't ideal for every pool. If there are cracks, trapped groundwater, or layers of old paint, the new coating may not last. Problems like peeling, bubbling, or a rough finish can develop, especially if the surface isn’t completely dry before applying the first coat.
If you want a smooth, long-lasting finish, consider alternatives like plaster or premium surfaces such as Diamond Brite. They cost more upfront but typically hold up better over time.
What Does It Cost to Paint a Gunite Pool?
The cost of painting your pool depends on pool size, condition, and prep needs, but it’s still one of the most affordable ways to refresh a gunite pool.
Here’s what you can expect:
Total cost: $1,000 to $2,500
Cost per square foot: $1.84 to $2.17
Pool paint: $100 to $200 per gallon
Labor: $45 to $65 per hour
Paint estimates by size:
Small pool: 3–4 gallons
Medium pool: 4–6 gallons
Large pool: 7–8+ gallons
Surface prep, like cleaning, acid washing, and drying the pool surface completely, affects both cost and paint performance. Applying a first coat, followed by a second coat, takes time, especially with epoxy paint, which needs ideal conditions to bond.
Prices may run higher in areas with elevated labor rates or unpredictable weather. Don’t forget to factor in the cost to drain, fill, and float the pool after curing. Compared to plaster or aggregate, pool painting offers short-term savings but requires more frequent upkeep.
How Long Does Pool Paint Last?
The life of your pool paint depends on the paint type, surface prep, and how well you maintain the pool water after painting.
Epoxy paint: 5–7 years
Water-based epoxy: 4–6 years
Chlorinated rubber: 3–5 years
Acrylic: 2–4 years
To get the most out of painting your pool, the pool surface must be cleaned, rinsed, and completely dry before applying the first coat. Poor prep or lingering ground water can lead to peeling or an unsightly appearance.
After painting, balanced water chemistry and proper care help extend the coating’s life. For longer results with less upkeep, plaster or aggregate finishes may be a better long-term choice.
What Paint Should You Use on a Gunite Pool?
Choosing the right pool paint is key if you want solid results that last. The wrong type or poor prep can lead to peeling, cracks, and an unsightly appearance.
Here’s a quick breakdown:
Epoxy paint lasts 5–7 years but needs thorough prep. It bonds best to bare pool surfaces or previously painted epoxy. Avoid applying it over incompatible coatings.
Water-based epoxy is easier to apply and still holds up for 4–6 years with good prep and dry conditions.
Acrylic is budget-friendly and easy to roll on, but it only lasts 2–4 years. Best if you're planning to resurface with plaster or another finish later.
Before painting your pool, research what’s on it now or get professional advice. The wrong match could cost more in repairs down the line. And if your pool walls have damage or moisture issues, painting alone won’t fix it.
Step-by-Step: How Painting a Gunite Pool Works
Painting your pool takes time, prep, and the right conditions. Skipping any part of the process increases the risk of failure in the long run.
Here's how it’s done:
Drain the pool and let the surface dry completely. If there's groundwater or moisture from rain, you'll need extra drying time to avoid bubbling or peeling later.
Scrub the floor and walls to remove debris, chemicals, and old residues. Use TSP or a strong acid wash, depending on what you're removing. Rinse thoroughly and allow time to dry again.
Check for cracks or surface damage. If repairs are needed, take care of them before applying any paint.
Tape off tiles, the patio, or other areas you don’t want painted.
Apply the first coat of paint with a roller designed for textured surfaces. Wait for it to dry, then apply the second coat.
Once the painting is done, let the surface cure for 5 to 7 days. Then you can fill and float the pool.
Painting your swimming pool isn’t a one-day job, and rushing it can lead to problems. Done right, though, it gives your house and backyard a fresh, clean look, even if only for a few seasons.
Common Problems with Painted Gunite Pools
Painting your pool can offer a quick refresh, but it often brings long-term issues.
Peeling, flaking, and bubbling are common when the surface isn’t dry or prepped well. Paint exposed to the sun can chalk, leaving cloudy water and uneven color on the pool floor and walls.
Painted surfaces also get rough over time, making it harder to clean and easier for debris or algae to stick. Most coatings come with limited or no warranty, which means more out-of-pocket repairs.
If you want longevity, painting may not be the best option. Many homeowners end up switching to plaster or aggregate to avoid repeat work.
Painting vs. Plastering vs. Aggregate Finishes
When comparing pool resurfacing options, painting might feel like the quickest solution, but it’s not always the best for the long run.
Painting your gunite pool has the lowest upfront cost and is often done in one day, but it offers the shortest lifespan. It’s a good short-term option if your patio needs attention, too, and you want to keep things simple for now. Just know you’ll likely be filling and draining your pool more often for touch-ups or repairs.
Plaster provides a smoother surface and a more durable result. It holds up better against chemicals, acid washing, and water pressure, with fewer issues from rain, debris, or sun exposure.
Aggregate finishes, like Diamond Brite, cost more but are built for longevity. They resist cracks, maintain color longer, and stand up well to shifting ground or water table issues. For homeowners who want fewer future projects, this finish offers peace of mind.
In short, if you want to create a polished look fast, painting works, but if you want fewer headaches later, research longer-lasting options before making the call.
DIY vs. Hiring a Professional
Thinking of painting your pool yourself? It can work, but there are a few things to weigh.
DIY painting typically costs $700–$1,400, depending on materials like paint, rollers, tape, safety gear, and tools. You’ll also need to handle all the prep: scrub the surface, mix and apply paint properly, and deal with any floor or wall damage beforehand. Many DIYers spend 40+ hours across multiple weekends getting it right.
Hiring a professional, on the other hand, costs $1,500–$2,500. But they’ll manage repairs, know how to handle issues like high water tables, and produce a cleaner, more durable result. They’ll also make sure the surface is fully dry, properly prepped, and painted in the right conditions to avoid peeling or chalking.
A bad DIY job often leads to repainting sooner or needing a full resurfacing. If you're looking for good reviews, reliable results, and fewer surprises, working with a contractor familiar with gunite pools might save more than it costs.
When NOT to Paint Your Gunite Pool
Painting your pool might sound easy, but in some cases, it’s a bad idea. Skip it if your pool already has multiple layers of peeling paint, ongoing issues with groundwater or a high water table, or signs of serious damage to the shape or surface.
If you plan to upgrade to plaster or an aggregate finish in the near future, painting might just delay the inevitable. And if you’re looking for longevity over a quick fix, painting doesn’t offer the best value in the long run.
Prior surface repairs or patch jobs can also interfere with how paint adheres. A fresh coat won't solve underlying problems. In these situations, painting can create more headaches than it solves.
How to Save Money Without Sacrificing Quality
To get the most from painting your gunite pool without overspending, a little planning goes a long way.
Bundle repairs like tile work or patio updates to reduce labor overlap.
Schedule in the off-season to take advantage of more flexible crews.
Keep up with your pool’s chemical balance to avoid damaging your new coating.
If you manage multiple properties or large pools, buying in bulk helps cut down costs.
Always request multiple bids from contractors who specialize in gunite surfaces and have good reviews.
Making smart moves early can help you create a cleaner, longer-lasting result without draining your budget or repeating the job before it's necessary.

Frequently Asked Questions
Is it okay to paint a gunite pool?
Yes, painting a gunite pool is okay in the right situation. If you’re aiming for a quick, affordable update, like before selling your house, it can do the job. Just know it’s a short-term fix.
Painted pools often peel, chalk, or fade, especially if the surface wasn’t fully dry or properly prepped. If longevity is the goal, painting your pool might be a bad idea. Plaster or aggregate finishes last longer and handle weather better.
How to prep a gunite pool for painting?
Prepping your pool right is key to making pool paint last. Here’s the basic process:
Drain the pool and let it dry fully (especially after rain).
Scrub the floor and walls with TSP or degreaser.
Use an acid wash if needed, then rinse well and let dry again.
Repair any cracks or damage before painting.
Tape off any areas you don’t want painted.
Apply the first coat, let it dry, then apply the second coat.
Skipping steps or rushing the cure time usually leads to peeling or bubbling.
Can you recolor a gunite pool?
Yes, you can recolor it with either new pool paint or a more permanent surface like plaster or aggregate. Just make sure you match the new paint type with whatever was used before (epoxy over epoxy, etc.).
Want lasting color and fewer problems? Consider resurfacing. It holds up better in the sun, resists fading, and won’t cloud your pool water like old paint might.
