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.

Can I Apply Concrete Sealer Myself?

Yes. Many of our concrete sealers are suitable for DIY application when used according to the manufacturer's instructions. Proper preparation and application are essential for achieving professional results.

How Do I Prepare Concrete Before Concrete Sealing?

Before applying concrete sealer, the surface should be clean, dry and free from dirt, grease, mould, algae, efflorescence and failing coatings. Depending on the condition of the concrete, preparation may involve pressure cleaning, degreasing, acid etching, grinding, crack repairs or coating removal.

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.

How Long Before I Can Drive On A Sealed Concrete Driveway?

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

Where Can I Find The TDS And SDS?

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 preparation, application, coverage, drying times, curing schedules and safety requirements.
