What Is The Best Concrete Sealer?

The best concrete sealer depends on the type of concrete surface, level of protection required and the finish you want to achieve. Solvent-based concrete sealers are popular for exposed aggregate, decorative concrete and concrete driveways because they enhance colour and can provide a semi gloss finish. Water-based concrete sealers are often chosen where lower odour and reduced VOC levels are preferred.

How Much Concrete Sealer Do I Need?

Coverage rates vary depending on the concrete sealer, surface type, porosity and number of coats applied. Use the coverage calculator located on each product page to estimate the amount of concrete sealer required for your project.

How Many Coats Of Concrete Sealer Should I Apply?

Most concrete sealers achieve the best results with two coats. Many water-based concrete sealing systems require a primer coat followed by two top coats. Always refer to the Technical Data Sheet (TDS) for product-specific recommendations.

How Long Does Concrete Sealer Last On Driveways And Exposed Aggregate?

Most concrete sealers last between 2 and 7 years depending on the product type, traffic levels, UV exposure, weather conditions and ongoing maintenance. Regular cleaning and maintenance can help extend the life of a sealed concrete surface.

How Do I Prepare New Or Green Concrete Before Sealing?

New concrete must be allowed to properly cure before applying concrete sealer. The surface should be clean, dry and free from curing compounds, laitance, debris and contaminants. Always refer to the Technical Data Sheet (TDS) for minimum curing times and preparation requirements.

Can Concrete Sealer Be Applied Over An Existing Sealer?

Application over an existing concrete sealer depends on the type and condition of the original coating. Some concrete sealers are compatible with existing coatings while others may cause adhesion issues, whitening, peeling, bubbling or coating failure.

What Is The Difference Between Solvent-Based And Water-Based Concrete Sealer?

Solvent-based and water-based concrete sealers are formulated differently and each has advantages depending on the application. Water-based concrete sealers are often chosen for their lower odour, easier cleanup and reduced VOC levels. Solvent-based concrete sealers are commonly used where fast drying times, compatibility with existing coatings or specific finish characteristics are desired.

Should I Dilute The First Coat Of Solvent-Based Concrete Sealer?

For dense or less porous concrete surfaces, the first coat is often diluted with up to 30% xylene to improve penetration and adhesion. For highly porous concrete, dilution is often not required. Always refer to the Technical Data Sheet (TDS) for product-specific recommendations.

Can Xylene Be Used For Concrete Sealer Cleanup?

Yes. Xylene is commonly used for cleaning rollers, brushes and equipment after applying solvent-based acrylic concrete sealers. It should only be used with compatible products and handled in accordance with the Safety Data Sheet (SDS).

How Long Before I Can Walk On A Sealed Concrete Surface?

Many sealed concrete surfaces can be lightly trafficked after approximately 3 to 5 hours and walked on after 12 to 24 hours following the final coat. Drying and curing times vary depending on the product and environmental conditions.

Surface Preparation

Thoroughly pressure clean the surface using a pressure washer capable of delivering a minimum of 2000 PSI to remove dirt, debris, loose material, and surface contaminants.

Where required, use a suitable concrete cleaning solution to remove oil, grease, mould, algae, and other contaminants. For dense or smooth concrete surfaces, use GAR (Ground Activation Reagent) or Hydrochloric Acid to etch the surface and open the pores of the concrete, promoting proper sealer penetration and adhesion.

Once preparation is complete, thoroughly rinse the surface to remove all residues and neutralise any remaining acid. Allow the concrete to dry completely before applying any sealer, coating, or primer.

Ensure the Prime Aqua Primer coat has adequately cured and dried before applying Prime Aqua Colour Top Coat.

The surface must be clean, dry, and free from contaminants that may affect adhesion or finish quality.

Application

Prime Aqua Primer must be used as the first coat before applying Prime Aqua Colour Top Coat to ensure proper adhesion and surface consolidation.

Stir thoroughly before use.
Apply an even coat using a 13mm nap roller or soft broom, ensuring there is no pooling of material.

For spray applications, apply:

1 coat of Prime Aqua Primer
2 coats of Prime Aqua Colour Top Coat

Under normal conditions (above 15°C with low humidity), allow a minimum of 2 hours between coats.

For optimum hardness, durability, and performance, allowing additional curing time between coats is recommended.

Where slip resistance is required, Anti-Slip Additives are available.

Application Conditions

While water-based sealers are generally more forgiving than solvent-based systems, correct application conditions remain critical for achieving the best results.

Apply only when air and surface temperatures are above 15°C.
Ensure air and substrate temperatures are at least 5°C above the dew point.
Apply during a cooling concrete cycle whenever possible.
Avoid application in direct sunlight or during rising concrete temperatures.
Do not apply during periods of high humidity, condensation, fog, mist, or when moisture is present on the surface.
Avoid application where environmental conditions may negatively affect curing, adhesion, appearance, or finish quality.

Important

Applying sealer during a rising concrete temperature cycle can cause trapped air within the substrate to expand and escape through the coating. This may result in bubbling, pinholing, blistering, or other finish defects.

HOW MUCH SEALER DO I NEED?

To calculate how much sealer you'll need, measure the length and width of each concrete area and multiply them together.

Formula:
Length (m) × Width (m) = Total Area (m²)

Example:
Driveway: 10m long × 4m wide = 40m²

If your project has multiple sections, calculate each area separately and add them together.

Tips:

• Measure in metres for the most accurate result.

• Include driveways, paths, patios and pool surrounds.

• Round up your measurements if unsure.

• Our calculator includes an allowance for product absorption and application rates.

CONCRETE SEALING & SEALER FAQ'S

Coverage rates vary depending on the product, surface type, porosity and number of coats applied. Use the coverage calculator above to estimate the amount of sealer required for your project. Porous surfaces typically require more product, while dense or previously sealed surfaces often achieve greater coverage. Always allow a small amount of extra product to ensure complete coverage.

Most concrete sealers achieve the best results with two coats. The first coat penetrates and bonds to the surface, while the second coat provides additional protection, durability and finish enhancement. Highly porous concrete may require additional product or coats to achieve the desired appearance and performance. Always refer to the product Technical Data Sheet (TDS) for specific application recommendations.

Yes. Many of our products are suitable for DIY application when used according to the manufacturer's instructions. Proper surface preparation, suitable weather conditions and correct application techniques are essential for achieving professional results. Always read the Technical Data Sheet (TDS) before commencing your project.

The surface should be clean, dry and free from dirt, grease, mould, algae, efflorescence and any existing failing coatings. Depending on the condition of the concrete, preparation may involve pressure cleaning, degreasing, acid etching, grinding, crack repairs or coating removal. Proper preparation is critical to achieving good adhesion and long-term sealer performance.

New concrete must be allowed to properly cure before sealing. The recommended curing period varies depending on the type of sealer being used and the manufacturer's recommendations. Before sealing, the surface should be clean, dry and free from curing compounds, laitance, construction debris and contaminants that may affect adhesion.

Some concrete surfaces may require acid etching, grinding or pressure cleaning to open the surface and promote sealer penetration. Always refer to the product Technical Data Sheet (TDS) for minimum curing times and preparation requirements before application.

Application over existing coatings depends on the type and condition of the original sealer. Some products are compatible with existing coatings, while others may cause adhesion issues, whitening, peeling or coating failure. If your concrete has previously been sealed, we recommend performing a compatibility test or contacting us for advice before application.

It depends on the porosity of the concrete and the weather conditions during application. For dense or less porous concrete surfaces, we generally recommend diluting the first coat with up to 30% xylene to improve penetration and adhesion. This helps the sealer soak into the surface rather than sitting on top, resulting in better bonding and long-term performance.

For highly porous concrete, dilution is often not required as the surface will readily absorb the sealer. Depending on the porosity of the concrete, additional coats may be required to achieve the desired finish and protection.

Always refer to the product Technical Data Sheet (TDS) for specific dilution recommendations.

Yes. Xylene is commonly used for cleaning rollers, brushes and equipment after applying solvent-based acrylic concrete sealers. It can also be used during maintenance and recoat applications to help soften and reactivate compatible solvent-based acrylic sealers.

However, xylene is a powerful solvent and can damage, soften or remove incompatible coatings, paints, plastics, rubber, asphalt and certain decorative finishes. Always test in an inconspicuous area before use and avoid contact with surfaces that may be affected by strong solvents.

Xylene should only be used with compatible solvent-based products and must be handled in accordance with the Safety Data Sheet (SDS). Always ensure adequate ventilation, wear appropriate PPE and follow all safety precautions during use.

Under normal weather conditions, most sealed surfaces can be walked on within 24 hours of the final coat. Drying times may vary depending on temperature, humidity, product type and ventilation. Refer to the product Technical Data Sheet (TDS) for specific drying and curing information.

For most concrete sealing applications, vehicle traffic should be kept off the surface for approximately 5 to 7 days after the final coat. This allows the sealer to properly cure and develop maximum durability. Premature vehicle traffic may damage the coating and affect the final finish.

Technical Data Sheets (TDS) and Safety Data Sheets (SDS) are available on each product page under the Downloads section. These documents contain important information regarding coverage rates, surface preparation, application methods, drying times, safety requirements and product limitations. We recommend reviewing the TDS and SDS before commencing any project.
