Plaster haze, mineral scaling and construction dust have to come off a new or resurfaced pool before it is filled. We acid wash the interior, clear the debris and hand it back neutralised.
After plastering, rendering or a resurface, the interior of a pool carries a fine mineral haze left behind as the finish cures, along with construction dust, cement residue and whatever else has found its way in while the site was open. Fill it in that condition and all of it goes into the water — which means a cloudy pool, chemistry that will not balance, and a filter working overtime from day one.
An acid wash strips that layer off and takes the surface back to the finish underneath it. It is the difference between a pool that comes up clear in a day and one that fights its owner for a fortnight.
It is precise work with a genuinely hazardous product, which is the real reason it is a specialist call rather than a Saturday job. Dilution, dwell, sequence and neutralisation all have to be right, the interior has to be handed over chemically neutral, and the waste has to be dealt with properly rather than tipped down the nearest drain.

The interior is prepared and wetted down first, the wash is worked in controlled sections so no area is left dwelling longer than it should, and the surface is neutralised immediately afterwards rather than left to be someone else’s problem.
Spent solution is contained and neutralised as part of the job. It does not go into the stormwater system, and it does not go into your garden.
New pools, washed and neutralised ready for the first fill.
After replastering or a new interior finish, where the same haze appears.
Calcium and mineral banding on an empty pool interior.
Dust, render splatter and site debris removed before filling.
Regularly engaged by pool builders and landscapers as the final step before handover.
Balancing, dosing and ongoing water care belong to your pool contractor.
Equipment and pool plumbing are a licensed trade. We work on the shell.
The pool needs to be empty for this work. Emptying and any structural considerations are your pool professional’s call.
Cracks, delamination and failing interiors get photographed and handed back, not repaired.
This is a one-off preparation job, not a maintenance contract.
Acid washing suits plaster and rendered interiors. Fibreglass and vinyl are a different conversation — ask before you book.
Short list, but every item on it is a genuine prerequisite rather than a preference.
And it needs to stay empty for the duration. Coordinate this with your pool contractor first.
Plaster, render, pebble or fibreglass — the finish decides whether this is the right method at all.
Where spent solution is contained and neutralised, agreed before anything is mixed.
Getting gear to a pool through a finished landscape is often the hardest part of the day.
An empty pool and a hazardous product together mean exclusion zones, and no children or pets on site while we work.
Best filled promptly after neutralising. Worth having the water booked before we arrive.
Usually booked by a builder, occasionally by an owner, always at the very end of a project.
Size, interior finish, whether it is a new build or a resurface, and when it needs to be ready.
Pool work gets looked at in person. Access and containment are not things imagery can answer.
In writing, naming the interior, the surrounds and the handover condition.
Exclusion zone set, containment arranged, interior condition photographed.
Worked in controlled sections, then neutralised and rinsed. Waste contained and dealt with properly.
Interior handed back neutral and ready to fill, with the photo record for your file.

Most commonly right at the end of a build or a resurface, once the interior has cured and before the first fill. It is also used on an empty pool carrying heavy mineral scaling or a stained waterline.
Yes — the pool has to be empty and stay empty while the work is done. Draining and any structural considerations around an empty shell are a call for your pool contractor, so coordinate that first.
On plaster and rendered interiors it is a standard part of the build sequence when it is done correctly — controlled dilution, controlled dwell, and neutralised straight afterwards. Fibreglass and vinyl interiors are a different question, so tell us what yours is before you book.
Spent solution is contained and neutralised as part of the job. It does not go into stormwater and it does not go into the garden.
Regularly. Builders and landscapers use this as the last step before handover, so the pool their client sees for the first time is genuinely finished.
