FAQ

Frequently Asked Questions

Concrete acid washing is a powerful cleaning method using a safe acid solution to remove tough stains, dirt, grime and mineral buildup from concrete surfaces. It's especially effective for heavily stained driveways, patios and pool areas.
Acid washing is ideal for removing stubborn stains, mould, rust and difficult marks that regular cleaning methods can't remove. It restores the concrete's appearance by revealing a fresh, clean surface.
Yes. When performed by professionals, acid washing is safe and effective. Metro uses the right solution in controlled amounts, ensuring excellent results without damaging your concrete.
The process generally takes a few hours depending on the size and condition of the surface. The surface typically takes about 24 hours to fully dry before any sealer is applied.
Never. All work is completed by our own trained in-house crew from start to finish. This means consistent quality, accountability and peace of mind on every single job.
We offer two types: a Natural Look Sealer that penetrates the surface enhancing its natural colour without a film, and a Wet Look Sealer that provides a glossy or matte finish ideal for indoor areas and pool surrounds.
Concrete sealer typically lasts 1-3 years depending on the type, surface conditions and exposure to wear. Regular maintenance can extend its lifespan.
We service all of New Zealand including Auckland, Wellington, Christchurch, Hamilton, Tauranga, Palmerston North, Queenstown and all surrounding areas. Contact us to confirm your location and we'll get you a fast, free quote.
Yes. Acid washing is highly effective at removing oil stains, tyre marks and grease buildup from driveways and concrete surfaces. For very heavy oil staining we may pre-treat the area before the full acid wash to achieve the best result.
Not necessarily. As long as we have access to the area being cleaned and a water supply, we can complete the job without you needing to be present. We'll confirm the details with you when booking.
We take care to protect surrounding garden beds and rinse the area thoroughly after washing. We recommend keeping pets off the surface until it has fully dried and been rinsed, which is typically within a few hours.
For most residential surfaces, acid washing every 2-3 years is sufficient to keep them looking their best. High-traffic areas or surfaces exposed to heavy staining may benefit from more frequent cleaning. Sealing after washing significantly extends the time between cleans.
Water blasting uses high-pressure water to remove surface dirt and grime, while acid washing uses a chemical solution to break down and lift deep-set stains, mineral deposits and discolouration that water pressure alone cannot shift. For heavily stained surfaces, acid washing delivers a significantly deeper clean.
