Why should I coat or paint a concrete surface?

Untreated concrete is porous and prone to staining, dusting, cracking, and moisture penetration over time. A quality concrete coating seals the surface, protects against oil stains, weather, and wear, and makes the area easier to clean while improving its overall appearance.

A sealer penetrates the surface and protects against moisture and staining while often allowing the concrete’s natural look to show through, whereas a concrete paint or coating sits on top of the surface, providing a solid colour finish along with protection. The right choice depends on whether you want to change the look of the concrete or simply protect it.

Yes, concrete coatings are commonly used on driveways, garage floors, and other high-traffic areas to protect against oil stains, tyre marks, and general wear while improving appearance. Shieldcoat has been used for driveway coating projects in New Zealand, with customers noting strong results in finish, colour, and durability.

Concrete should first be inspected for cracks or damage, with any issues repaired before coating. The surface then needs to be cleaned thoroughly to remove dirt, debris, moss, or any existing loose coatings so the new coating can adhere properly.

It is also important to note that concrete holds moisture for a long time and will need to be dry before coating. Where possible a moisture reader is great to check the level of moisture in the substrate however you can alsways do an adhesion/bubbling test on a small area to check prior to coating. 

This depends on the product, surface preparation, and how much traffic or weather exposure the area gets. Specialised systems designed for concrete, applied correctly by an approved applicator, can offer long-term protection.
