Concrete Sealing Adelaide

What is concrete sealing?

Concrete sealers are applied to concrete to protect against water penetration, surface damage, corrosion, and staining. They either obstruct the pores in the concrete to lessen the absorption of water and salts, or form an impermeable layer which keeps such materials from passing through.

Concrete is typically a blend of water, Portland cement, and aggregate. When mixed, the concrete becomes slurry and is poured and hardens into the material you are more familiar with. This material may also include rebar or steel support. Added substances and retarders might be included at the time of the pour to expand the strength or slow the drying time.

Tools are typically used to float the concrete which will make it smooth. As the concrete cures, it then hardens. Concrete does not dry out on its own but undergoes a slow chemical process that solidifies it. When concrete isn’t properly cured, it can lead to various problems including, cracking and dusting. The cure and seal can be used by a contractor to speed up the curing process; keeping the concrete hydrated and protected.

One of the best examples of the effectiveness of concrete sealers is your driveway.

As a homeowner, wouldn’t you want to do everything in your power to protect your biggest investment?

Many homeowners often ignore the importance of sealing their driveways. However, concrete driveways, especially in climates that experience freeze/thaw cycles, or have a mediterranean climate like South Australia, will benefit immensely from infiltrating and topical sealers that strengthen the surface and repel water, mold, oil, and salt.

This type of proper maintenance of your driveway and concrete surfaces around your home spares you money in the long run and is always worth the minimal upfront investment.

Benefits of Concrete Sealing for Adelaide Homes & Businesses

Concrete sealing protects surfaces from damage caused by moisture, chemicals, and daily wear. Unsealed concrete absorbs water, leading to cracks and surface deterioration over time.

• Sealers create a protective barrier that repels water, oil, and other contaminants, preserving the concrete’s integrity.
• Stain resistance is another key advantage, preventing unsightly marks from spills, vehicle fluids, and dirt.
• Sealing also enhances the concrete’s durability, reducing maintenance costs and extending its lifespan.
• For businesses, properly sealed concrete improves the appearance of storefronts, pathways, and parking areas, creating a professional and well-maintained look.

Common Problems That Concrete Sealing Helps Prevent

Unprotected concrete is vulnerable to several types of damage. Water penetration weakens the surface, leading to cracks that expand over time. Oil and grease stains from vehicles create permanent discolouration if not sealed properly. Mold and mildew develop in damp areas, making surfaces slippery and hazardous. UV exposure causes fading and surface degradation, especially in Adelaide’s hot climate. Without sealing, concrete is also more susceptible to dusting, where fine particles break loose, creating a chalky residue. Applying a high-quality sealer prevents these issues, preserving both function and appearance.

Types of Concrete Sealers & Their Uses

Choosing the right sealer depends on the concrete’s location, level of exposure, and desired finish.

• Penetrating sealers absorb into the concrete, offering long-term protection against moisture and stains without altering the surface’s appearance.
• Topical sealers form a protective layer on top of the concrete, enhancing durability and aesthetic appeal.
• High-gloss sealers create a polished look, while matte finishes provide a natural appearance.
• Slip-resistant sealers are ideal for driveways, patios, and walkways, adding an extra layer of safety.

Each type serves a specific purpose, ensuring concrete remains in top condition for years.

How Often Should Concrete Be Sealed?

The frequency of resealing depends on exposure to weather, traffic, and surface use. Driveways and high-traffic areas typically require resealing every two to three years, while patios and indoor concrete surfaces may last longer before needing reapplication. Heavy rainfall, prolonged sun exposure, and frequent vehicle traffic shorten the lifespan of a sealer, making regular maintenance essential. Signs of wear, such as fading, water absorption, or surface roughness, indicate that resealing is necessary. Keeping up with a proper sealing schedule prevents costly repairs and maintains the concrete’s protective barrier.

How Concrete Sealing Protects Against Adelaide’s Climate

South Australia’s Mediterranean climate exposes concrete to intense sunlight, occasional heavy rains, and fluctuating temperatures. Without sealing, UV rays break down the surface, leading to fading and brittleness. Rainwater seeps into unsealed concrete, causing expansion and contraction that leads to cracks over time.

Sealing provides a weather-resistant barrier, preventing moisture damage while maintaining colour and strength. Temperature fluctuations are another concern, as they contribute to surface movement and deterioration. Applying a high-quality sealer helps concrete withstand Adelaide’s climate, reducing maintenance and ensuring long-term durability.

The Concrete Sealing Step by Step Process

Here are some tips to help apply concrete sealer properly.

Here’s the step-by-step summary guide of how to seal concrete:

• Remove all oil, stains, dirt, grease, and dust from the concrete.
• Strip any existing sealer from the surface.
• Open up the concrete using an etching solution.
• Apply a thin coat of sealer with a roller or a sprayer.
• Wait for the first layer of sealer to dry up.
• Then, apply a second coat in the opposite direction.
• Lastly, allow the sealer to fully dry before walking or driving on the concrete.
• Although we understand people do attempt DIY sealer application, it’s very rare to see it go as planned with surface prep the number one culprit for coating failures well before they’re supposed to so please either do your due diligence and get the right equipment or get a professional to assist you, with The Driveway Doctor, your results are guaranteed!

DIY vs. Professional Concrete Sealing: Which is Best?

Applying concrete sealer requires proper surface preparation, the right materials, and careful application techniques. Many DIY projects fail due to inadequate cleaning, uneven application, or using the wrong type of sealer. Professional sealing ensures the surface is properly cleaned, free of contaminants, and sealed with high-quality products suited to specific conditions.

Professionals also use commercial-grade sealers that last longer than store-bought alternatives. Inadequate sealing leads to premature wear, requiring additional work and expense. For a long-lasting and effective solution, hiring a professional provides better results and eliminates common DIY mistakes.
