Acid washing is used to give a washed out look on concrete aggregate, and can also be used to provide a surface texture. Effectively the surface laitance are melted to give a stipple effect.
Acid washed surfaces are used for outdoor areas.
ANTI SLIP COATINGS
Anti slip finishes vary depending on personal preference – it can come in different colours and grit levels.
Bathrooms, high traffic areas, footpaths, wet areas and commercial freezers can all benefit from anti-slip coatings – basically anywhere that could be slippery.
We can mix anti-slip into any sealant that we put down, we can also lay epoxy resins with quartz, or we could grind a concrete slab then bush hammer and seal
Terraflake coatings are sometimes referred to as “flake” floors.
Flake floors can be used when concrete can’t be polished – this is a coated surface treatment. It is sometimes chosen when 2 slabs of concrete are poured at different times, so to polish would leave too different a finish.
It is also usually applied in high traffic area – a perfect flooring solution for public amenities for a hygienic, easy to clean flooring solution, such as public toilets, campground kitchens or bathroom facilities.
There are a vast array of finish options to choose from. Click here to read more
CONCRETE FLOOR REPAIRS

Stained concrete is an inexpensive but attractive alternative to polished concrete. This method involves applying acid or water-based stains to the concrete surface to create colors and patterns. Stained concrete retains the natural texture of concrete and creates a unique, artistic look. This is a cost-effective way to make your floor look beautiful with minimal maintenance. We recently stained concrete at the Costco in Auckland.
