If you need to resurface a gunite pool, you are usually dealing with a finish that is worn out, stained, rough, or cracking. Resurfacing fixes the interior finish so the pool looks better, feels smoother, and stays watertight. It can also be the right time to upgrade tile, coping, or your surrounding hardscape.
Key Summary
- To resurface a gunite pool, the pool is drained, the old finish is prepped or removed, repairs are made, then a new finish (plaster, quartz, pebble) is applied, followed by start-up water care.
- Most resurfacing projects take about 5 to 10 days of on-site work, but weather, repair needs, and finish choice can stretch the schedule.
- National cost ranges commonly land between $6,000 and $15,000, with averages around $11,000 depending on pool size and finish type.
- Finish costs often range by material, plaster is commonly cheaper than quartz, and pebble finishes are typically the highest cost per square foot.
- Many homeowners replaster on a 7 to 15 year cycle depending on water chemistry, use, and environment.
What it means to resurface a gunite pool
Resurfacing a gunite pool means replacing or refinishing the interior surface that you touch and see (often plaster or an aggregate finish). Gunite is the structural shell. The finish is the protective layer that gives your pool its color, texture, and smoothness. When that finish wears down, resurfacing restores it.
If you are looking at broader upgrades (new waterline tile, coping, skimmers, lights, or plumbing improvements), that is typically handled as part of a larger renovation. That is where pool renovations come in.
How do you know it is time to resurface a gunite pool?
Here are common signs homeowners notice before they resurface a gunite pool:
- Rough or sharp spots that scrape feet, hands, or swimsuits.
- Staining that does not improve with normal brushing and balanced chemistry.
- Cracking, crazing, or flaking on the interior finish.
- Discoloration or a “blotchy” look across the surface.
- Frequent dusting, where plaster residue seems to show up often.
Timing varies, but many owners plan for replastering in roughly the 7 to 15 year range, depending on conditions and frequency of regular maintenance.
The pool resurfacing process, step by step
Homeowners often ask what the actual process looks like. Here is a straightforward overview of how most crews resurface a gunite pool.
Step 1: Drain the pool and protect the site
The pool is drained and the work area is protected. This includes setting up for dust control and safe access. If groundwater is a concern in your area, a builder may take extra precautions to reduce risks during drainage.
Step 2: Remove or prep the old finish
The existing surface is chipped out or mechanically prepped so the new finish can bond. The amount of removal depends on the condition of the pool and the finish being installed.
Step 3: Inspect the shell and make repairs
This is where cracks, hollow spots, or bond beam issues get addressed. If the pool needs structural repair work, this can affect both cost and timeline.
Step 4: Apply the new finish
The new interior finish is applied (plaster, quartz, pebble, or another approved system). The finish choice impacts price, texture, color depth, and expected longevity.
Step 5: Fill the pool and complete start-up water care
After application, the pool is filled and the “start-up” period begins. This step is not optional. It is where brushing, filtration, and water balancing protect the new surface as it cures. Industry guidance notes that cement-based plaster cures significantly over the first 28 days, which is why start-up care matters so much.
If you want ongoing help beyond start-up, regular pool maintenance is a practical next step for many homeowners, and may extend the life of your pool.
How long does it take to resurface a gunite pool?
In many cases, the on-site work for resurfacing lands in a range of about 5 to 10 days. Weather delays, repair scope, and finish selection can push it longer. Some sources note 5 to 7 days as common, while others recommend planning closer to 1 to 2 weeks depending on conditions. Also, keep in mind there are two “timelines” homeowners care about:
- Construction timeline, the days the crew is actively working.
- Start-up timeline, the first few weeks where chemistry and brushing protect the new finish (often most important in the first month)
How much does it cost to resurface a gunite pool?
Most homeowners want a real number. The honest answer is that cost depends on pool size, the finish you choose, and how much repair work is needed before the new surface goes on.
National pricing guides commonly put pool resurfacing in the $6,000 to $15,000 range, with averages around $11,000.
What changes the price the most?
- Pool size and shape, more surface area costs more, and complex shapes take more labor.
- Surface condition, more cracking, delamination, or bond issues increases prep and repair time.
- Finish selection, higher-end aggregates cost more up front.
- Tile, coping, and decking scope, resurfacing is often bundled with upgrades.
If you are also considering outdoor upgrades around the pool, this is the moment to look at possible improvements to decking and patios, since access and staging are already part of the job.
What questions should homeowners ask before resurfacing?
What finish should I choose for my pool?
Plaster is often the simplest and lowest-cost option, while quartz and pebble finishes can offer different textures and longer-term durability depending on the product and care. Cost ranges by finish type can vary meaningfully, so it is worth comparing samples in person.
Can I swim right away after resurfacing?
Usually, no. You typically need to wait until the finish is filled, balanced, and cleared for use based on the finish type and start-up procedure. The early curing period is critical for long-term results, and cement-based plaster curing is heavily concentrated in the first 28 days.
Will resurfacing fix leaks?
Resurfacing can address some surface-level issues, but leaks often come from plumbing, fittings, or structural cracks that require separate diagnosis and repair. A proper inspection during the prep stage helps confirm what is really going on.
Should I renovate other parts of the pool at the same time?
Often, yes, if you already know you want to update tile, coping, lighting, skimmers, steps, or water features. Bundling pool renovations can reduce repeat labor and avoid tearing up the same areas later.

How to get an accurate quote for resurfacing
If you want a quote that holds up, plan on a site visit. A good estimate should reflect:
- Surface area and depth profile
- Current finish condition and any visible failures
- Repair needs, including cracks and bond issues
- Finish selection and any tile or coping scope
- Access constraints (tight yards, fencing, staging areas)

Frequently Asked Questions
What does it mean to resurface a gunite pool?
To resurface a gunite pool means replacing the interior finish (often plaster or an aggregate finish) that covers the gunite shell, so the surface looks and feels new again.
How often do you need to resurface a gunite pool?
Many homeowners consider resurfacing or replastering every 7 to 15 years, depending on water chemistry, use, and environmental conditions.
How long does it take to resurface a gunite pool?
Many resurfacing projects take about 5 to 10 days of active work, but repairs and weather can push it closer to 1 to 2 weeks in some cases.
How much does it cost to resurface a gunite pool?
National cost guides often place pool resurfacing around $6,000 to $15,000, with an average near $11,000, depending on pool size, finish type, and repair needs.
Why does water chemistry matter so much after resurfacing?
Water chemistry matters because new cement-based plaster is curing and hardening during the start-up period, with a large portion of curing occurring within the first 28 days, so balanced water helps protect the finish while it stabilizes.
