Specialised Concrete Sealing

Concrete sealant creates a much-needed barrier between your concrete surfaces and outside factors from the weather to oils, chemicals and grease.

Your concrete surfaces are designed to withstand the toughest conditions. But without regular sealing, moisture can penetrate your driveway, patio or poolside area and damage concrete from within.

At Concretis, we work with clients throughout Brisbane and across the Gold Coast to ensure their concrete surfaces look great and remain damage-free for longer. Our specialised sealing service tackles the challenging Queensland climate, ensuring that driveways, patios, and walkways stay resilient and visually appealing.

We use top-grade sealants for moisture, stain, and wear resistance, prolonging your surfaces’ lifespan. Our local experts offer custom solutions for both residential and commercial properties. Whether you’re looking to revive an aged surface or protect a new concrete slab, trust us for quality, reliability, and lasting outcomes.

How do I know if I need concrete sealing?

Deciding whether you need concrete sealing involves evaluating factors like:

  • Concrete age and condition: Newly laid surfaces should be sealed post-curing, usually within a month of installation. For older surfaces, signs of wear such as cracks or discolouration are key indicators.
  • Exposure to Elements: Frequent exposure to extreme weather increases the necessity for protective measures.
  • Usage Frequency: Areas with heavy foot or vehicle traffic, like a driveway, might need more frequent attention.
  • Previous Maintenance: Reapplication is typically needed every 2-5 years, so check your last maintenance date.
  • Visual Signs: Water absorption signs, such as darkening when wet, suggest the need for sealing.
  • Slip Resistance Requirements: For safety in places like pool areas, a non-slip additive is beneficial.
  • Aesthetic Desires: Desired finishes, such as gloss or colour enhancement, are achievable through sealing.

How long does concrete sealing take?

At Concretis, we understand the need to minimise the disruption of a concreting job. Whether it’s your home, your business or any other setting, we pride ourselves on a fast and efficient job without cutting corners.

For concrete sealing, preparation might take a few hours to a few days, depending on the surface state. The sealing process for an average area might take hours, but the complete procedure, including drying, can span one to three days. Sealant type, weather conditions, and workforce size also influence the duration. Note that sealants also require additional curing time before the area is fully usable.

Types of Sealers

Concretis has a wealth of experience in the application of concrete sealants for all Residential, Commercial and Industrial projects.

Penetrative Sealers

As the name suggests, penetrative sealers penetrate into the concrete substrate. This type of sealer will not affect the surface appearance of the concrete and they are generally used to make the structure less porous, by limiting the amount of water and pollutants absorbed by the concrete. Penetrative sealers help protect the concrete, but as they do not sit on the surface of the concrete, they will not negatively impact upon the slip resistance of the finish.

Surface Sealers

Surface sealers/ hard sealers sit on the surface of the concrete and include acrylic and polyurethane sealants (both water-based and solvent-based formulas are available). There are numerous types of surface sealers and these can be used to:

  • Enhance the look of decorative concrete (e.g. polished concrete, coloured concrete, exposed concrete)
  • Protect the concrete in high traffic areas
  • Protect concrete structures (e.g. concrete benches, furniture, and benchtops)
  • Provide specific resistance (e.g. anti-graffiti, chlorine repellent, fuels, and oil resistant)
  • Can also be mixed with additives (e.g. powdered glass or glass beads to improve grip and slip resistance of the surface)

Frequently Asked Questions About Concrete Sealing in Brisbane & Gold Coast

Yes. Sealing concrete offers numerous benefits, including protection from damage, enhanced durability, reduced maintenance, aesthetic preservation, cost-effectiveness, UV resistance, and chemical resistance. Despite the need for periodic reapplication and the initial cost, the advantages typically outweigh these factors. Without proper sealing, your surfaces may lose their look and experience rapid damage from the elements.

The lifespan of a sealer varies by type. Acrylics usually need reapplication every 1-3 years, while epoxy and urethane sealers can last 5-10 years. Penetrating sealers offer up to 5 years or more of protection, and polyaspartic sealers have a lifespan of 5-10 years. Lifespan is affected by traffic, weather, maintenance, and application quality. For accurate maintenance scheduling, consult a professional for an assessment of your specific conditions.

Our commitment to quality and compliance is evident in every aspect of our work, especially in our choice of sealants.

1. Epoxy Sealers:

Widely recognized in the industry for their strength and durability, epoxy sealers form a resilient, non-porous layer on concrete surfaces.

Ideal for high-traffic areas and commercial applications, these sealers comply with industry standards for wear resistance, chemical resistance, and longevity.

They are particularly suited for facilities that require a balance of functionality and aesthetic appeal.

2. Polyurethane Sealers:

Offering a similar level of protection as epoxy but with enhanced flexibility, polyurethane sealers are another staple in our range.

Their compliance with industry standards extends to areas like UV resistance, making them ideal for both interior and exterior applications. This type of sealer is often used in spaces where a durable yet visually appealing finish is required.

3. Penetrating Sealers:

For projects where maintaining the natural look of concrete is paramount, penetrating sealers are our go-to choice.

Complying with industry standards for moisture resistance and longevity, these sealers are absorbed into the concrete to protect it without altering its appearance.

They are often used in historical buildings or architectural projects where preservation is key.

4. Acrylic Sealers:

Offering a cost-effective solution for projects where budget considerations are as critical as performance, our acrylic sealers comply with industry standards for basic protection against water and surface wear.

They are suitable for less demanding applications where a moderate level of protection is sufficient.

We ensure that all our sealing materials comply with Australian Standards (AS), including AS 3799-1998 for Liquid membrane-forming curing compounds for concrete, and other relevant industry guidelines. This compliance not only guarantees the performance of our sealants but also their safety in terms of VOC emissions and environmental impact.

In addition to using top-tier sealing materials, our advanced diamond grinding machinery, equipped with the latest dust extraction systems, ensures a pristine application environment.

This approach minimises dust and airborne contamination, which is crucial in sensitive architectural and corporate projects, further aligning with industry best practices and environmental safety standards.

By combining high-quality materials with state-of-the-art equipment and techniques, we deliver sealing solutions that stand the test of time and adhere to the strictest industry standards, ensuring satisfaction for our discerning clientele in the construction and architectural sectors.

Post-sealing maintenance of concrete surfaces is crucial to ensure their longevity and aesthetic appeal, especially in commercial or architectural settings.

Here’s an overview of the typical maintenance required and its frequency:

1. Regular Cleaning:

The most basic and essential maintenance is regular cleaning. This involves sweeping or gently washing the surface to remove dirt, debris, and any spills. For commercial settings or high-traffic areas, daily or weekly cleaning might be necessary.

In less trafficked areas, a bi-weekly or monthly schedule may suffice.

2. Periodic Deep Cleaning:

In addition to regular cleaning, a more thorough deep cleaning is recommended. This usually involves using a pH-neutral cleaner and a soft brush or mop to remove any ingrained dirt or stains.

Depending on the level of traffic and the environment, deep cleaning might be needed quarterly or bi-annually.

3. Stain Removal:

Immediate attention to spills, especially of harsh or staining substances like oil, chemicals, or acidic liquids, is important. Quick removal helps prevent stains from setting in.

Using appropriate cleaners for different types of stains is crucial, and in some cases, professional cleaning may be required for stubborn stains.

4. Sealer Reapplication:

Over time, the effectiveness of the sealer will diminish, necessitating reapplication. The frequency of resealing depends on the type of sealer used, the level of wear and tear, and environmental exposure.

Generally, resealing is recommended every 1 to 5 years. Acrylic sealers may require more frequent reapplication (every 1-3 years), while more durable sealers like epoxy, polyurethane, and penetrating sealers might last 3-5 years or more before needing another coat.

5. Repair of Cracks or Damage:

Regularly inspect the surface for any cracks, chips, or other damage. Early detection and repair can prevent further deterioration and are essential for maintaining the structural integrity and appearance of the surface.

6. Avoiding Harsh Chemicals:

Maintenance should involve avoiding harsh chemicals or abrasive cleaning tools that could damage the sealer or the concrete surface. Gentle, non-abrasive cleaners are recommended.

7. Professional Inspection:

Periodic inspection by a professional can help assess the condition of the sealed surface and recommend any necessary maintenance or repairs. This is especially important for high-value commercial or architectural projects.

By adhering to a regular maintenance schedule and promptly addressing any issues, the longevity and appearance of sealed concrete surfaces can be maximized, ensuring they remain functional and visually appealing for as long as possible.

The performance of concrete sealants under various environmental conditions is a critical factor in their selection and application, particularly in environments subject to UV exposure, rain, temperature fluctuations, and chemical exposures.

Here’s an overview of how different types of sealants typically perform under these conditions:

1. UV Exposure:

  • Acrylic Sealers: They provide good UV protection, preventing colour fading and degradation of the concrete. However, over time, they can become brittle or yellow under constant UV exposure.
  • Epoxy and Polyurethane Sealers: While offering robust protection against UV rays, some epoxy sealers may yellow over time. Polyurethane sealers are generally more UV-resistant and less prone to yellowing.
  • Penetrating Sealers: These sealers do not change the appearance of the concrete and are not affected by UV light, making them an excellent choice for outdoor applications where maintaining the natural look of concrete is essential.

2. Rain and Moisture:

  • Acrylic Sealers: They provide a good barrier against water but may need reapplication more frequently in areas with heavy rainfall.
  • Epoxy and Polyurethane Sealers: These offer excellent water resistance, making them suitable for areas that are frequently wet.
  • Penetrating Sealers: Highly effective at protecting against water penetration, they are ideal for preventing damage from freeze-thaw cycles and reducing the risk of efflorescence and mould growth.

3. Temperature Fluctuations:

  • Acrylic Sealers: While they handle moderate temperature changes well, extreme fluctuations can cause them to crack or peel.
  • Epoxy and Polyurethane Sealers: These sealers perform well under temperature changes. Polyurethane, in particular, offers more flexibility, which is beneficial in environments with significant temperature swings.
  • Penetrating Sealers: Their ability to penetrate deep into the concrete makes them less susceptible to damage from temperature changes.

4. Chemical Exposures:

  • Acrylic Sealers: They offer basic protection against chemicals, but may not be sufficient for areas exposed to harsh chemicals.
  • Epoxy Sealers: Excellent for industrial or commercial settings, epoxy sealers provide strong resistance to a wide range of chemicals.
  • Polyurethane Sealers: Similar to epoxy, they offer robust chemical resistance, suitable for garages, workshops, and areas where chemical spills might occur.
  • Penetrating Sealers: While providing good general protection, they may not be as effective as epoxy or polyurethane in high-exposure chemical environments.

Each type of sealer has its strengths and weaknesses, and the choice depends on the specific environmental conditions the concrete will face.

For instance, in coastal areas with high UV exposure and salt air, a UV-resistant and moisture-resistant sealer would be ideal.
