Unsealed Concrete? You're Asking for Trouble.
Without a proper seal, your concrete absorbs water, oil, and grime like a sponge. Over time, this leads to stains, surface breakdown, cracks, and mould. Sealing helps lock out moisture and dirt while enhancing colour and finish—so your concrete stays clean, tough, and great-looking all year round.
Water Damage and Moisture Penetration
Unsealed concrete can absorb water, leading to cracks and surface erosion over time. A suitable sealer creates a protective barrier, which is particularly valuable in Dunedin's wet and freeze-thaw conditions.
Protect Against Oil, Grease and Chemical Stains
Driveways, patios and garage floors are exposed to vehicle fluids, spills and cleaning products. Sealing helps repel stains and makes the surface easier to clean and maintain.

Frequently Asked Questions
Helpful guidance for planning a durable concrete project in Dunedin.
Why is concrete sealing important?
Sealing protects concrete from moisture, UV exposure, stains and surface wear. It also enhances decorative finishes and can extend the life of the surface.
How often should I reseal my concrete?
Most concrete should be resealed every two to five years, depending on traffic, exposure and the product used. Driveways may need more frequent attention than sheltered patios.
What types of sealer do you use?
We use commercial-grade products suited to the concrete type and finish, including penetrating or surface sealers and clear matte or gloss options.
Will sealing make my concrete slippery?
Some gloss sealers can become slick when wet. A non-slip additive can be included for sloped, exposed, or frequently wet areas.
Can you seal old concrete?
Yes. Older concrete can be sealed after thorough cleaning and any necessary repairs. New concrete should cure fully before sealing.
