Frequently Asked Questions

What type of finishes are available in coloured concrete?

Your coloured concrete can be finished in a variety of methods to create the look you want. Some of the popular finishes include broomed, coved, polished, stamped, trowelled and burnished.

How long does resurfacing take?

It will normally take 2 days to resurface and seal an average sized driveway.

Is resurfacing expensive?

Resurfacing an existing concrete surface is usually more cost-effective than replacing it with new concrete. Prices generally vary from $40-$60 per square metre depending on preparation, design and finish.

Can a new concrete slab be resurfaced?
Yes, as long as it has cured for at least 28 days.
What is the coverage rate of sealer?
Normal coverage for a first coat is approx 3-5m² per litre depending on the porosity of the concrete. Subsequent coats should deliver 5-6m² per litre of sealer.
How long will sealer take to cure?
Curing times will depend on the ambient weather conditions and can vary from job to job. However, it is recommended that the sealed surface does not have foot traffic for at least 24 hours and vehicle traffic for at least 5 days.
What affects the life expectancy of a sealer?

Weather conditions and the type and frequency of traffic all play a part in the longevity of sealers. Traffic over excess dirt, friction (e.g. from tyres), and other excessive wear and tear (e.g., power steering or heavy traffic) may reduce the life of the sealer. Constant UV exposure may also reduce the life of the sealer. Regular maintenance can help extend the life of the sealer.

How will l know when my concrete surface needs to be resealed?

If your concrete appears faded and dull and darkens when it’s wet, it is time to reseal. Generally, surfaces need to resealed every 2 years.

How long will sealers last?

Wear and tear and changes in appearance of your decorative finish will tell you when a surface needs to be resealed.  The volume and type of traffic will impact on wear and tear.

As a guide:

  • Residential driveways coated with an acrylic should be recoated between 18 months to 2 years after the finish is applied then 3 to 5 years after.
  • Commercial or highly abraded environments that use penetrative, urethane and epoxy sealers will require re-coating in 3-8 years.
Can I reseal myself?

This is not recommended as there are variables to resealing that an inexperienced person not be aware of.  Some existing coatings will need to be stripped and removed prior to resealing or a solvent wash could be required.

Every reseal will require a minimum of a 3,000psi water wash with a pH neutral degreaser such as CCS HD Degreaser to remove all stains and impurities.  The surface also needs to be totally dry before a reseal can commence.

Is a matt finish sealer less slippery than a gloss or satin one?
As these sealers are the same film thickness the slip factor will be the same. If a coating has a higher gloss level this does not necessarily mean that the coating is more slippery. Traction aids can be used in conjunction with CCS film forming if slippages are a concern.  Alternatively, consider a CCS penetrative sealer which will not change the surface texture.
Can  sand or glass be used to add grip to solvent based acrylic sealers?

Under no circumstances should sand or glass be used as a traction aid for acrylic sealers. Acrylic sealers are not thick enough to coat and surround such large particles such as sand and or crushed glass. There are specifically designed traction aids that are used in acrylic sealers. Consult our helpline on 1800 077 744 if traction is of concern.

Can I have polished concrete in an external area such as on my driveway or around my pool?

Take extreme caution as these finishes are very smooth.  Consult a specialist applicator who can visit your site to review options. An attractive alternative with superior grip is to use a CCS penetrative sealer on a lightly honed surface. Penetrative sealers do not affect the existing slip resistance of concrete surfaces due to their absorbent nature.

Will full depth concrete colour fade?
Pigments are integral or full depth, so colour is through the entire slab. CCS colours are UV stable and weatherproof.  If coloured concrete is looking a little dull it could well mean that the slab needs to be resealed or if not already sealed, may require cleaning to remove efflorescence or salts on the surface.
When should sealer be applied to my concrete?
If you have NEW concrete that has NOT been coated in CCS Same Day Sealer you will need to wait for the concrete to cure 28 days.

If you have NEW concrete and it HAS been coated with CCS Same Day Sealer a final coat of sealer should not be applied until the surface is uniform in colour and appearance.  This may take between 7 to 20 days.

If you have an EXISTING sealed surface, you can re coat after 24 hours of good weather after preparing the surface with a high-pressure water wash and degreaser.

Why do I have to wait that long?
As concrete is curing and drying it is contracting as well as releasing water, salt and lime.  If a coating is applied whilst the concrete is curing, there is potential for the coating to turn milky/cloudy or to delaminate.
Can pavers or tiles around my pool be sealed?

Please seek professional advice as resealing pavers, stones and tiles as it is a complex procedure. Slipping will occur with surface sealers.  For new unsealed, unglazed concrete pavers, consider sealing with a CCS penetrative sealer.

How much does it cost to seal concrete?

Product cost alone is typically costs $2-$8/m² depending on the product and surface porosity. Typically, product and labour will be $12-$30/m² depending on the requirements and the size of the project.

This is only a guide, a quotation should be obtained as prices will be subject to the size of the job, the complexity and access to the site.

I have a steep driveway. What sealer do you suggest?

There are many factors to consider, including the following – if the driveway has already been sealed, the current surface texture and if you choose colour.

CCS Penetrative Sealers will not change the surface texture.  CCS Acrylic Sealers will change the surface texture but may be suitable if there is sufficient texture in the current concrete substrate.

Ultimately, a test sample should be conducted to ensure the suitability of sealer on the surface. Discuss your needs with your applicator.

What colour should I choose?

Colour is a matter of personal choice and there is no right or wrong decision.  A simple solution is to work with your home’s existing palette. You can choose colours that either contrast with or complement it.  The colours that make up this palette can be found in the roof, gutters, fascia, window detailing, walls, landscaping and surrounding structures.

Seeking inspiration from other homes is always helpful. A visual diary using resources such as Pinterest, Instagram, magazines or even photographs of places you love can help guide you. If your home is an investment, consider colours that are timeless and will continue to add value to your property over time. Remember, while dynamic and fun, some colours can be a reflection of current fashion trends and may date by the time you consider resale.

When can I drive my car onto my newly sealed driveway?

With the exception of polyaspartics which are ready for use within 4-6 hours, most CCS sealers are only touch dry in 1-4 hours.  After this time, the surface can be walked on but it is important to avoid driving or moving garbage bins or furniture on freshly sealed concrete for 7 days.

How do I clean concrete that’s been sealed with a penetrative sealer?
It’s important to maintain and clean your concrete surface, even when it has a sealer applied. We recommend cleaning solutions such as CCS HD Degreaser or CCS Citric Cleaner. For further instructions and advice, download our guide to cleaning and maintaining surfaces sealed with CCS Penetrative Sealers here.
How do I clean and maintain concrete that’s been sealed with commercial sealer?
It’s important to maintain and clean your concrete surface, even when it has a sealer applied. If you have used a commercial grade CCS sealer such as Armourthane, Armourgard SP, Decrathane and Rapid Floor Polyaspartic, we recommend you download our guide to cleaning and maintaining surfaces sealed with CCS Penetrative Sealers.
How do I protect my new decorative concrete floor?
We strongly recommend that any decorative flooring system be completed with a premium CCS sealing product. Different sealers will result in different appearances, but all sealers will offer protection against incoming grime, dirt and oil. A sealer will also make cleaning and maintenance much easier and retain the beauty of your decorative concrete surface for years to come.
