The versatility and durability of decorative concrete makes it one of the most suitable surfaces for a multitude of environments. And just as each environment is different, so too are the sealers that are required. Consideration should be given to the look you want to achieve, location, abrasion and chemical resistance, maintenance limitations, site access challenges and slip resistance. As a long term leading supplier to the industry, CCS are very familiar with these requirements. We are continually researching, testing, modifying and adding sealers to our range – to meet the ever changing needs of the concrete industry throughout Australia and overseas.

Sealed vs Unsealed

The above photo demonstrates the difference between an unsealed (right hand side) and sealed section (left hand side) of the same concrete surface after several years of weathering. The sealed section of the concrete remains clean after many years whereas the unsealed section (with the pen) is dirty due to the accumulation of grime and dust.

Types of Sealers

There are four main types of sealers that are applied to concrete. Each of these sealers has different features which make them suitable for particular situations.

  • Acrylic Sealers (all purpose coatings)
  • Urethanes (extremely tough and durable)
  • Penetrating Sealers (penetrates into surface and provides a natural look)
  • Epoxy Sealers (for internal use)

Acrylic Sealers

Acrylic sealers, such as CCS Hardseal and CCS Hi-Build Enduro, are the most widely used and preferred coating in the concrete industry. They are UV resistant, relatively easy to apply, can be applied soon after concrete installation, are economically priced and have excellent recoating abilities.

Acrylic sealers are ideal for exposed aggregate, full depth coloured concrete, stencil concrete, pattern concrete and Stylepave resurfacing systems.

Additives to Enhance Traction / Slip Resistance

To assist in aiding traction, crushed glass or specially manufactured synthetic powders such as CCS Sealer Grip can be used with most sealers. Additives however cannot be used in conjunction with non-film building, penetrating sealers such as CCS Streetscape Sealer.

With crushed glass the applicator broadcasts the material into the first coating of sealer while it is still wet. As a rule, crushed glass such as CCS Glass Beads are used in Epoxy and Urethane Coatings only. A second coating of sealer is then applied to lock the grit into the surface. In contrast, special additive powders such as CCS Sealer Grip are mixed with Solvent based sealers such as the range of CCS Acrylic Sealers, prior to the final coat. The degree of slip resistance is directly relative to the amount of additive per litre of sealer mix. Therefore, it is recommended that a sample be specified prior to commencement of the project.

Please Note: The above additives will only aid traction. Existing smooth surfaces that do not satisfy Australian Standards for slip resistance cannot be rectified by adding CCS Sealer Grip. It is also important to note that as the sealer wears, the traction additives will also diminish in effectiveness.
