Concrete Protective Sealers
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)
- Epoxies (for internal use) (please refer to the ACS range of coatings and sealers)
Acrylic sealers, such as CCS Hardseal , 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.

CCS Urethanes are available in both water based or solvent based formulas. Urethane sealers such as CCS Armourthane and CCS Decrathane , are much thicker than acrylic sealers and are extremely resistant to physical and chemical attack and will usually last several years before needing reapplication.
CCS Urethane Sealers are ideal for polished and honed concrete and are an integral component of the CCS Platinum Polished Concrete System
Their abrasion resistance is approximately 3 to 4 times greater than acrylic sealers. Consequently, they are the ideal sealer for indoor and outdoor areas such as shopping centre walkways, cafe floors, amusement parks and other areas subject to constant pedestrian or light vehicular traffic.Drawbacks:-
- The emission of a strong odour during application.
- They are relatively sensitive to airborne moisture and therefore need to be applied during daytime.
- When renewing the sealer (after several years), the surface will require sanding to ensure an effective bond to the new coating.
- They are more expensive than acrylic sealers.
The above drawbacks are insignificant for new construction sites, however the use of urethanes for renovating floors in an occupied building, for example, requires consideration.

> CCS Decrathane Satin
> CCS Decrathane Semi Gloss
In contrast to the three other sealers, silane and silane siloxane sealers such as CCS Natural Seal Supreme HV and CCS Streetscape Sealer do not create a coating and are therefore good for surfaces where slip resistance and retaining a natural look may be issues. They are often referred to as 'penetrating' sealers because they absorb into the concrete to repel the ingress of moisture while allowing vapour to escape from the inside of the surface.
For larger pedestrian and public eating areas, where staining may be an issue, CCS Streetscape Sealer and the premium CCS Stain Block offer excellent resistance to oil based stains. CCS Stain Block also offers excellent resistance against food stains and stains left from chewing gum residue.
Although they can be used for horizontal surfaces, silane based sealers such as CCS Natural Seal Supreme are most commonly used for coating exterior vertical walls - to stop wind driven rain and salt from penetrating the concrete and causing the reinforcing steel to rust and eventually spall the concrete.Also in the CCS penetrating sealer range is the water based CCS Densifier. CCS Densifier works to harden, densify and dustproof concrete floors. When applied, the sealer imparts a low sheen which enhances the appearance of the concrete while retaining a natural look.
Because of their excellent penetrative nature, CCS penetrating concrete sealers will not alter the general appearance or texture of decorative concrete (Note:- CCS Streetscape Sealer and CCS Densifier will impart a low sheen which may make the surface slightly darker). Hence, if you want to gain the benefits of sealing concrete but desire the natural look, CCS penetrating concrete sealers are ideal and in many cases, they can also be used for protecting and sealing concrete pavers, natural stone and porous tiles.Please refer to individual data sheet links below or call your nearest office for further information.
