Rough texture, staining, calcium deposits, and surface cracks are signs your pool needs resurfacing. Swimpool 360 applies plaster, pebble aggregate, quartz, and fibreglass finishes across Toronto and the GTA. Transform your tired pool into a smooth, beautiful surface that lasts for years.
When your pool's interior surface becomes rough, pitted, stained, or develops hairline cracks, pool resurfacing GTA specialists at Swimpool 360 restore it to a clean, functional finish. We offer four primary resurfacing types suited to Ontario's climate and pool types. Pool plaster Toronto homeowners choose includes our classic white plaster option - affordable, smooth, and readily available, lasting 7-12 years with proper water chemistry. Quartz aggregate surfaces blend marble dust with quartz crystals for a harder, more stain-resistant finish that lasts 12-18 years and comes in a range of colours.
Pebble aggregate finishes embed small smooth stones into the surface matrix, creating a natural, slip-resistant texture that can last 15-25 years and handles Ontario freeze-thaw cycles very well. For fiberglass pools, we apply specialized fiberglass coating systems that bond to the gelcoat substrate and restore the waterproof barrier. Each surface type has distinct maintenance requirements, cost profiles, and aesthetic characteristics that our team will walk you through before you decide. For vinyl pool owners, pool liner replacement is the equivalent renovation for your pool type. See our complete pool renovation services overview to understand how resurfacing fits within a broader pool update.
Ontario pools take significant wear from seasonal cycles. If you run your hand along the pool wall and it feels rough or chalky, or if swimmers are leaving with scratched skin, resurfacing is overdue. Visible staining that does not respond to acid washing, dark patches at the waterline, surface crazing, or calcium nodules forming on the shell are all indicators. For pool surface repair Ontario clients, we address small surface cracks that are stable (not structural) during resurfacing before water penetrates deeper.
Pools that have developed a rough, sand-like texture underwater - a condition called delamination - need professional assessment and typically full resurfacing to restore the seal. When plaster begins to dissolve, it elevates calcium hardness and pH, forcing you to use more chemicals to maintain balance. This is a clear sign the surface is failing and should be addressed before it creates a water chemistry cycle that becomes increasingly expensive to manage.
Complete draining of your pool using a submersible pump. Takes 6-8 hours depending on pool volume. All water removed before any surface work begins.
Full acid wash to neutralize alkalinity, remove calcium scale, and prepare a clean bond surface for the new finish. Eliminates existing staining before new material is applied.
Any stable structural cracks are patched with hydraulic cement before the new finish is applied. Prevents water infiltration and ensures the new surface has a sound substrate.
White plaster is hand-troweled in two coats. Quartz and pebble finishes are applied in layers and hand-finished to a smooth or textured result, depending on the finish selected.
Pool is refilled immediately after the final coat to prevent shrinkage cracking. Refilling takes 12-18 hours depending on pool size and water source.
Startup chemicals are added over the first 28 days to cure the new surface and protect it from staining. We provide a startup schedule and advise on water chemistry targets for the cure period.

The resurfacing process begins with draining your pool completely - typically 6-8 hours using a submersible pump. Once drained, our crew performs an acid wash to neutralize alkalinity and remove calcium scale, giving the new surface a clean bond surface. Any structural cracks are patched with hydraulic cement before the new finish is applied.
White plaster is hand-troweled in two coats. Quartz and pebble finishes are applied in layers and hand-finished to a smooth or textured result. The pool is refilled immediately after the final coat to prevent shrinkage cracking. Startup chemicals are added over the first 28 days to cure the new surface and protect it from staining. Maintaining proper water chemistry during this cure period is critical - pH should remain 7.2-7.6 and calcium hardness between 200-400 ppm. Our team will provide a detailed startup schedule and remain available to answer chemistry questions throughout the curing period.
The pool resurfacing cost Toronto and GTA homeowners can expect typically ranges from $6,000 to $18,000 depending on pool size, surface type selected, and the condition of the existing surface. White plaster is the most affordable option at $6,000-$9,000 for a standard 30,000L pool. Quartz finishes range from $9,000-$14,000 and offer a harder, more colourful surface. Pebble aggregate resurfacing costs $12,000-$18,000 but delivers the longest lifespan - typically 15-25 years.
All pricing includes draining, acid wash, crack patching, new surface application, refill, and the first phase of startup chemicals. Pools with significant damage, unusual shapes, or extensive crack repairs may incur additional costs. When surface deterioration is caught early, our pool repair team may be able to address isolated cracks before a full resurface becomes necessary. We provide fully itemized quotes after an on-site assessment so you know exactly what is included. For ongoing protection of your newly resurfaced pool, our pool maintenance and service plans help maintain the water chemistry that extends surface life significantly.
Choosing the right pool surface depends on your budget, how long you plan to stay in your home, your tolerance for maintenance, and the aesthetic you want to achieve. White plaster gives your pool a classic, clean look and is the fastest to apply and most economical to install. However, it is the most porous of the three options and more susceptible to staining from minerals and algae if water chemistry drifts. It also tends to feel slightly rough as it ages.
Quartz aggregate surfaces are substantially harder than plaster, more resistant to chemical etching, and available in colours ranging from bright white to deep grey-blue. Quartz is the most popular choice among GTA homeowners wanting an upgrade from plaster with a reasonable price increase. Pebble aggregate finishes offer the greatest durability and a distinctly natural aesthetic that suits outdoor environments in Oakville, Vaughan, and other GTA communities where backyard design is a priority. The Pool and Hot Tub Council of Canada identifies proper surface selection and water chemistry management as the two most impactful factors in the longevity of any pool interior finish.

Ontario's climate creates unique demands on pool surfaces that warmer climates do not face. Freeze-thaw cycles put stress on all pool surfaces as water expands and contracts in micro-pores within the shell and finish layer. Pools that are not properly winterized - or that drain partially after closing - are especially vulnerable to surface spalling and cracking. GTA pools with white plaster surfaces tend to show frost damage within 10 years if not maintained correctly.
Hard water is another Ontario-specific factor. Municipal water in Toronto, Mississauga, and the surrounding GTA has elevated calcium hardness levels (typically 150-300 ppm straight from the tap). Over time this leads to calcium scaling on pool surfaces and tile lines. Proper water balancing using a Langelier Saturation Index calculator helps prevent scaling. When resurfacing GTA pools, we account for local water chemistry and recommend surface types that perform best under these conditions. Pebble aggregate and quartz surfaces are particularly well-suited to Ontario's hard water environment.
