It's never too late to seal or reseal your concrete surface!
With proper preparation, old concrete can be given a dramatic facelift with your choice of CCS Sealer. Adding colour to your existing surface is also possible with CCS Colour Master Sealer (mixed together with your desired CCS Sealer Tint).
Unsealed Concrete
Preparation usually includes a pressure clean, degreasing to remove oil stains, and a light acid etch and wash. Once these steps are completed and the concrete is dry, sealing can commence.
Previously Sealed Concrete
Care and patience are required when recoating previously sealed concrete surfaces. The critical ingredient to a satisfactory job is to ensure that the new coat of sealer bonds to the existing sealer coat as well as the concrete surface. To successfully achieve sufficient bonding, recoating of sealed concrete (sealed with acrylic) should occur within 2 1/2 years of initial coating.
As the initial coating ages, it may react with the concrete below to form a very hard, yet somewhat brittle layer of sealer. The hard sealer layer can be difficult to dissolve when new sealer is applied, causing whitening problems at a later date. To avoid such problems, we recommend applying the sealer in full sunlight (for exterior surfaces) to a small area - approximately 2m2, and evaluating the surface after six weeks, to determine if the sealers are bonding satisfactorily. If whitening occurs on the sample area, consult our technical staff by phoning 1800 077 744 as it may be necessary to use CCS Fusion Seal or a stripper to treat the existing coating.
