Water repellent sealer

These sealers penetrate deep into the concrete to form a protective barrier that repels water and oil-based stains. Penetrating sealers do not change the appearance of the concrete surface and are ideal for use on outdoor surfaces such as walls, driveways and sidewalks.

Acrylic sealers

These are the most common type of sealers and they are available in both water-based and solvent-based formulations which act as a surface coating. Acrylic sealers come in glossy or wet finish and are available in different colours. These sealers are ideal to resurface exterior areas such as patios, decks and driveways.

Self Cleaning Sealer

These sealers use a chemical process known as photocatalysis to break down pollutants in the air. These sealers contain titanium dioxide, a catalyst that reacts with UV light from the sun to convert harmful nitrogen oxides (NOx) into harmless compounds that can be washed away by rainwater. Ideal for exterior walls, buildings, bridges as it does not change the colour or appearance of the concrete surface.

Ecotone systems

Concrete-like staining systems: Ecotone coatings are specialized coatings used to color and protect concrete surfaces. Designed to penetrate deeply into the concrete surface, they create a permanent and natural-looking finish. They're ideal for both interior and exterior concrete, block, and brick walls. Bespoke colors are available.

Anti-graffiti sealers

Anti-graffiti sealers are specialized coatings designed to protect surfaces from graffiti and other forms of vandalism. They can be used on a variety of surfaces, including concrete, brick, metal, and painted surfaces, and are typically formulated to be easy to clean and resistant to various solvents and chemicals.

FAQs

Sure, here are some frequently asked questions about concrete sealers:

What types of concrete sealers are available?

There are several types of concrete sealers available, including acrylic, epoxy, polyurethane, penetrating, and silane/siloxane sealers.

What is the difference between solvent-based and water-based sealers?

Solvent-based sealers contain volatile organic compounds (VOCs) that evaporate during application, while water-based sealers are made with water as the main solvent. Water-based sealers are generally more environmentally friendly and easier to clean up, while solvent-based sealers offer better penetration and adhesion.

What is the best sealer for outdoor concrete surfaces?

Penetrating sealers are generally the best choice for outdoor concrete surfaces such as driveways and sidewalks, as they provide a water-repellent barrier that can withstand heavy traffic and exposure to the elements.

Can concrete sealers be used on interior surfaces?

Yes, concrete sealers can be used on interior surfaces such as floors and countertops to protect against stains, scratches, and wear and tear.

How often should concrete sealers be reapplied?

The frequency of reapplication depends on the type of sealer and the conditions of use. Some sealers may need to be reapplied every 1-2 years, while others can last up to 10 years or more.

What is a photocatalytic sealer?

A photocatalytic sealer is a type of concrete sealer that uses a chemical process called photocatalysis to break down pollutants in the air. These sealers contain titanium dioxide, a catalyst that reacts with UV light from the sun to convert harmful nitrogen oxides (NOx) into harmless compounds that can be washed away by rainwater.

How do anti-graffiti sealers work?

Anti-graffiti sealers work by creating a protective barrier on the surface that makes it difficult for graffiti and other substances to adhere to. The coatings are typically designed to be nonporous and easy to clean, so any graffiti or other marks can be removed without leaving a residue or damaging the surface.

Do every concrete structure needs to be sealed if not painted?

Not all concrete structures necessarily need to be sealed if they are not painted. However, applying a sealer to a concrete structure can provide several benefits, including protection against moisture, stains, and UV damage. If a concrete structure is located in an area with frequent exposure to water or other liquids, such as a patio or a garage floor, sealing the concrete can help prevent water infiltration and reduce the risk of staining or discoloration.

Similarly, if a concrete structure is located in an area with high levels of UV exposure, such as a driveway or a sidewalk, sealing the concrete can help protect against UV damage and prevent the surface from becoming brittle or discolored. Additionally, sealing concrete can help prolong the life of the structure by reducing the risk of cracks, spalling, or other forms of damage caused by exposure to the elements.

It's important to choose the right type of sealer for your specific concrete surface and application, and to follow the manufacturer's instructions for application and maintenance.
