Concrete Coating in Perth
A concrete coating is a protective and decorative layer applied over an existing slab. Where polishing refines the concrete itself, a coating covers it, which makes it the right answer for surfaces that are stained, patchy, previously repaired or simply not attractive enough to leave exposed.
Coatings suit garages, workshops, patios, alfresco areas, pool surrounds, driveways, warehouses and commercial floors. The right system seals the surface against oil, chemicals and moisture, improves slip resistance where it is needed, and gives you control over colour and texture that bare concrete cannot offer.
Coating Systems We Work With
Epoxy coatings give a hard, chemical-resistant film that suits garages, workshops and industrial floors. Polyurethane topcoats add UV stability and flexibility, which matters outdoors where an epoxy alone would chalk and yellow. Flake and quartz systems broadcast decorative chips into the coating for texture, grip and a finish that hides marking.
For outdoor areas, spray-on and stencil overlays rebuild the surface with a textured cementitious layer that can be coloured and patterned, while penetrating sealers protect without changing the look. We match the system to the exposure, the traffic and the finish you are after.
Preparation Decides Whether A Coating Lasts
Coating failure is almost always a preparation failure. A coating will only hold if the surface beneath is sound, clean and correctly profiled, which means mechanically grinding or shot blasting the slab rather than acid etching or simply cleaning it.
Moisture is the other common cause. A slab drawing moisture from below will push a coating off regardless of how well it was applied, so slabs without an effective membrane need testing and, where required, a moisture-tolerant primer before any coating goes down.
Frequently Asked Questions
Helpful answers for Perth property owners planning concrete driveways, repairs, resurfacing and durable concrete surfaces.
What is the difference between a coating and polished concrete?
A coating is a layer applied over the slab. Polished concrete refines the slab itself. Coatings give more control over colour and can hide a poor surface, while polishing gives a finish that cannot peel.
How long does a concrete coating last?
A well-prepared and correctly specified coating commonly lasts many years. Lifespan depends on the system used, traffic, UV exposure and how well the slab was prepared.
Can you coat an outdoor area or driveway?
Yes, with a UV-stable system. Straight epoxy is not suitable outdoors on its own because it chalks and discolours, so a polyurethane topcoat or an outdoor-rated overlay is used instead.
Will a coating fix cracks in my concrete?
Coatings can bridge fine cracks and hide surface imperfections, but they do not repair structural cracking. Moving or structural cracks need repair first and may still show through.
Are coated floors slippery?
Slip resistance is controlled by the finish. Flake, quartz or an anti-slip additive in the topcoat gives grip for wet areas, while a smooth gloss finish suits dry interiors.
Can you coat over an existing coating?
Sometimes, if the existing coating is sound, compatible and correctly prepared. Where it is peeling or of unknown origin, removing it is the safer option.
