What we do
Mechanical pool grinding for surfaces that need more than a brush
Old marbelite gets rough. Scale builds up. Lippage forms where patch jobs were never feathered in. Pool grinding fixes all of that by mechanically removing the top layer until the surface is smooth, even and ready to swim against or refinish over.
Skynet Pools brings industrial pool grinders, diamond pads and dust control to your site. We grind back the failed surface in controlled passes, leaving a true, even shell that a new marbelite, fibreglass or mosaic finish can bond to properly.
Our pool grinding crews work across Pretoria East, Centurion, Waterkloof, Lynnwood, Menlyn, Garsfontein, Wapadrand, Mooikloof and the surrounding suburbs.

Why grind your pool
What proper pool grinding gives you
Six reasons Pretoria homeowners book pool grinding instead of trying to brush, sand or chemically strip their pool.
Smooth feel
No more grit underfoot, no scraped knees and toes. Grinding restores the silky feel a pool should have.
Lippage removed
Old patch jobs and step ledges are levelled flush so the eye and the foot read the surface as one continuous plane.
Scale stripped
Calcium scale and stains are mechanically removed where chemicals and brushing have stopped working.
Perfect prep
A properly ground shell gives marbelite, fibreglass and mosaic finishes the bite and bond they need to last.
Avoid full rebuilds
Often grinding alone, or grinding plus a fresh coat, saves you the cost of a full remarble or shell rebuild.
Controlled and clean
Industrial grinders with dust control mean we work clean, protect your garden and never gouge your shell.
Our process
How we grind your pool
A clear path from drain down to a smooth, prepped surface. You always know what is happening on site and what comes next.
- 01
Free site visit
We meet you on site, inspect the surface, identify scale, lippage and rough zones, and decide whether grinding alone is enough or if a refinish is needed.
- 02
Quote and plan
You receive a written, itemised quote with the grinding scope and any optional refinish work. Approve before any work begins.
- 03
Drain and protect
The pool is drained safely, lights and drains are masked, and surrounding paving and plants are protected from dust and debris.
- 04
First grinding pass
Industrial grinders with diamond pads work the surface in controlled passes, taking off scale, lippage and the failed surface layer.
- 05
Polish and inspect
Finer grit pads polish the shell to a smooth, even surface. We inspect every wall, the floor and the steps before signing the work off.
- 06
Clean and hand over
The pool, deck and surrounds are cleaned of all dust. We hand over a perfectly prepped shell ready to refill or refinish.
Surfaces we grind
Every surface, every shape
From compact courtyard plunges to long lap pools, every Skynet grinding job is tailored to the surface in front of us.
Rough marbelite
Ground back to a smooth, even plane ready for refinish or to extend life on a structurally sound surface.
Scaled finishes
Heavy calcium and mineral scale removed mechanically when chemical treatments have stopped working.
Lippage and ridges
Old patch joins, ridges and step edges levelled flush so the surface reads true from end to end.
Pre-fibreglass prep
Shell ground and keyed to give fibreglass linings the bond and grip they need to last decades.
Pre-marbelite prep
Old failed plaster ground back so fresh marbelite goes on a clean, sound, properly profiled shell.
Concrete shells
Raw or rough concrete shells from new builds and resizes ground to spec before the finish goes on.
Grinding methods
The right grit for the right surface
Pool grinding is not one tool with one pad. We use different grinders, different abrasive grades and different speeds depending on what the surface needs. The result is always the same: a smooth, even, ready-to-finish shell.
Diamond grinding
Diamond pads remove failed marbelite, heavy scale and stubborn ridges in controlled, even passes.
Polishing
Fine grit pads polish the surface after grinding so it feels smooth underfoot and looks even under water.
Acid wash finish
An optional acid wash after grinding lifts colour and removes the last of the staining for a brighter pool.

Frequently asked
Pool grinding questions, answered
The questions Pretoria homeowners ask us most before booking pool grinding.
How long does pool grinding take in Pretoria?
A typical pool grinding job takes 2 to 4 working days from drain down to a smooth, fully prepped surface. Timing depends on pool size, the condition of the existing finish and how much material needs to be removed.
What does pool grinding actually do?
Pool grinding mechanically smooths rough, pitted or scaled pool surfaces. It removes lippage, evens out high spots and prepares the shell so a new marbelite, fibreglass or mosaic finish bonds correctly.
How much does pool grinding cost in Pretoria?
Pricing depends on pool size, the condition of the surface and how much material needs to be ground back. After a free site visit we send a written, itemised quote so you see every line item before approving.
Can pool grinding remove a rough surface without a full remarble?
In some cases yes. If the marbelite is structurally sound but rough or showing minor lippage, grinding alone can restore a smooth surface. If the plaster is failing, grinding is the prep step before resurfacing.
Does grinding damage the pool shell?
No. Grinding only removes the surface layer. Our crew controls the depth carefully so the structural concrete shell underneath is never compromised, only cleaned up and profiled.
Will I need to refinish my pool after grinding?
Often yes. Grinding is usually a prep step ahead of remarbling, fibreglass lining or mosaic tiling. In some cases a polish and acid wash after grinding is enough to restore the pool to a useable, smooth state.
Is pool grinding messy?
Grinding produces dust, but our equipment includes dust control and we mask the surrounding deck and plants. We clean the pool, surrounds and decking before handing over.
