Maintaining your investment
Decorative concrete must withstand some pretty harsh conditions in our Canadian climate. We provide proper maintenance, using top quality protective products that will greatly extend the life of your decorative concrete surface. Understanding our climate will help you understand why routine maintenance is critical:
Rain and Wind
When it rains water is absorbed into the concrete, and then the water expands as it freezes. Concrete sealers protect your project from snow, wind, rainfall and high temperature.
Snow and Ice
Salt and chemicals used to melt the ice in northern climates can allow moisture and chemicals to soak into the surface of the concrete. When the temperature drops, the water freezes and expands, which can crack the concrete or damage the surface finish.
The sun’s UV rays can degrade sealers, fade colours and bake stains into the concrete. A proper sealant protects your concrete and can save you big money in replacement and repair in the future.
Cleaning is the cornerstone of maintenance. It is a critical and necessary step, because concrete is so porous. A simple pressure wash with water and low pressure, from 1000 to 1800 psi is acceptable in most decorative applications as this will dislodge the debris from the porous concrete, without chipping the surface. For driveways, patios and sidewalks, a good pressure wash once or twice a year will do the job. The use of a scrub brush also works well to clean joints and other hard-to-reach areas. Light detergents at low concentration can also be used, not acid mixtures, which can attack the concrete.
Once the surface is cleaned and dry, it must be protected from the elements and from wear and tear with a high quality sealer that repels water, limits damage from UV sunlight and resists abrasion. Resealing can make the color look fresh again, but it’s important that the surface be maintained properly from the start. The use of a top quality sealer makes cleanup easier, improves the looks of the project and extends the life of the decorative application.
Sealing should be done once every two years, or more often, depending on the local environmental conditions and wear and tear of the decorative concrete surface.
