Concrete SealingBrisbane — Long-Lasting Protection for Every Concrete Surface

For most Brisbane driveways and outdoor surfaces, we recommend a penetrating silane-siloxane sealer because it soaks into the concrete rather than sitting on top, which means it won’t peel or flake under heavy UV and rain exposure. Film-forming acrylics work well for decorative concrete where you want a subtle sheen, but they need recoating more frequently in high-traffic areas. We assess your surface and recommend the right system on-site.

Most penetrating sealers are touch-dry within two to four hours in typical Brisbane conditions and fully cured within 24 hours. Film-forming acrylics and polyurethanes generally need four to six hours before light foot traffic and 48 hours before vehicle traffic. Higher humidity slows cure times, so we schedule application for optimal conditions and give you specific timelines for your job.

Yes, but we need to identify the existing sealer type first. Applying a new sealer over an incompatible product causes peeling, whitening, or delamination. We carry out adhesion testing and solvent checks on-site to determine what’s already there. If the old sealer is failing, we strip it back using diamond grinding or chemical strippers before resealing — proper preparation is non-negotiable for a lasting result.

Penetrating sealers on horizontal outdoor surfaces typically need reapplication every three to five years in Brisbane’s climate, while film-forming sealers may need attention every two to four years depending on UV exposure and traffic levels. You’ll know it’s time when water stops beading on the surface and starts soaking in. We can set up a maintenance schedule so your concrete stays protected year-round.

Sealing doesn’t prevent structural cracking from ground movement or poor slab design, but it significantly reduces surface cracking caused by moisture ingress and thermal cycling. By blocking water from entering the pore structure, a quality sealer prevents the expansion-contraction cycle that widens hairline cracks into visible damage over Brisbane’s hot summers. For existing cracks, we fill them with flexible polyurethane before sealing to prevent further moisture entry.

It depends on the area, the type and condition of the concrete, how much preparation is needed, and which sealer system suits the surface. Old failing coatings, oil stains and cracks all add preparation time.

Yes, and preparation is included in every concrete sealing job. We pressure clean the surface, treat oil stains with an alkaline degreaser and fill cracks with a flexible polyurethane filler. We then allow at least 24 hours of drying time before applying sealer. Sealing over dirty or damp concrete is the most common reason sealers whiten, peel or fail early.

A penetrating sealer soaks into the concrete and doesn’t create a slippery film, so the surface feels much the same as before. Film-forming sealers add a sheen and can be slicker when wet. For pool surrounds, ramps and walkways, we’ll recommend a suitable finish or an anti-slip coating so the area stays safe.

Yes. Exposed aggregate is one of the most common surfaces we seal in Brisbane. We use sealers that protect the stone without making it look artificially glossy. Pool surrounds and entertaining areas are also good candidates because they’re constantly exposed to water and chlorine. We choose the sealer for each area’s surface and use.

Concrete sealing is a clear coat. It protects the surface while keeping the natural colour, aggregate and texture visible. Concrete painting is an opaque coloured coating that covers the surface for a uniform new look and can hide imperfections. Choose sealing if you like how your concrete looks, and painting if you want to change it.

Yes. As well as Brisbane, we seal concrete across the Gold Coast, Sunshine Coast, Ipswich, Logan and Caboolture, using the same preparation and products on every job.
