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 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.

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).

CONCRETE SEALING & CONCRETE SEALER FAQS

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.

For the best results, choose a concrete sealer specifically designed for your surface type and application. If you're unsure which concrete sealer is right for your project, contact our team for advice.

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.

Porous concrete surfaces typically require more product, while dense or previously sealed surfaces often achieve greater coverage. We recommend allowing a small amount of extra product to ensure complete coverage and avoid running short during application.

Most concrete sealers achieve the best results with two coats. The first coat penetrates and bonds to the concrete surface, while the second coat provides additional protection, durability and finish enhancement. Many water-based concrete sealing systems require a primer coat to enhance adhesion, followed by two top coats for optimum durability and performance. Always refer to the Technical Data Sheet (TDS) for product-specific recommendations.

Highly porous concrete may require additional product or coats to achieve the desired appearance and performance. Always refer to the Technical Data Sheet (TDS) for specific application recommendations.

Most concrete sealers last between 2 and 7 years depending on the product type, traffic levels, UV exposure, weather conditions and ongoing maintenance.

Concrete driveways, exposed aggregate and other high-traffic areas may require more regular maintenance and resealing to maintain appearance and protection. Regular cleaning and proper maintenance can significantly extend the life of a sealed concrete surface.

Yes. Many of our concrete sealers 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 concrete sealing project and ensure all preparation requirements are followed.

Before applying concrete sealer, 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 for achieving good adhesion, maximum sealer penetration and long-term concrete sealing performance.

New concrete must be allowed to properly cure before applying concrete sealer. The recommended curing period varies depending on the type of concrete 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 Technical Data Sheet (TDS) for minimum curing times and preparation requirements before application.

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. If your concrete has previously been sealed, we recommend performing a compatibility test or contacting us for advice before application.

Solvent-based and water-based concrete sealers are formulated differently and each has advantages depending on the application. Both are available in a range of finishes and can provide excellent protection when applied correctly.

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.

The best choice depends on the surface type, existing coatings, desired appearance and project requirements.

If you're unsure which concrete sealer is suitable for your project, contact us for product recommendations.

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 allows the concrete sealer to soak into the surface rather than sitting on top, resulting in better bonding and longer-lasting protection.

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 Technical Data Sheet (TDS) for product-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.

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, temperature, humidity and environmental conditions. Always refer to the Technical Data Sheet (TDS) for product-specific drying and curing information.

For most concrete driveway sealing applications, vehicle traffic should be kept off the surface for approximately 5 to 7 days after the final coat.

This allows the concrete sealer to properly cure and develop maximum durability. Premature vehicle traffic may damage the coating, leave tyre marks or affect the final finish.

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

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, curing schedules, safety requirements and product limitations.

We strongly recommend reviewing the TDS and SDS before commencing any concrete sealing project to ensure the concrete sealer is suitable for your application and is used correctly.
