Living Stone Concrete Design’s concrete products are sealed with an environmentally friendly, water-based chemical hardener that bonds with the concrete. Maintaining your countertops is all that is required. If needed, touch-up sealer is available in the event of an accident or major wear.
To clean your concrete products, use damp cloths, mild detergents and other water-based cleansers with neutral pH. Our favorites are 409, Fantastik, Windex and Simple Green. Abrasive cleansers or scrubbers, like Comet, Brillo pads and 3M scrubbing pads, should be not be used.
Do not cut directly on the countertops. Knives will pierce the sealer, rendering the counters more susceptible to staining. Additionally, the concrete will severely dull the knife's cutting edge. Scratches in the sealer could occur if heavy, rough or sharp objects are dragged across the countertop surface.
Use normal care with respect to water, oil, acids and food. Spills should be wiped up as soon as possible. This is especially true for vinegar. Staining and discoloration can occur if staining agents are left on for an extended period of time.
As with almost all types of countertop surfaces, you should use trivets. Our sealer can withstand temperatures up to 400 degrees. Concrete can microcrack if exposed to heat more than 400 degrees, and the sealer is not elastic enough to “absorb” these microcracks. In this case, the surface may appear “crazed” if wetted.
Non-structural hairline cracks are possible and considered an inherent part of the product, not a manufacturing defect. Hairline cracks can occur at any time during the life of the countertop, but are usually not a common occurrence. Hairline cracks are defined as cracks, generally smaller than ½ mm in width that do not threaten the integrity or stability of the slab nor prevent the continued and normal use of the countertop.
While durable, both concrete and natural stone are “brittle” materials. Sharp edges are more susceptible to chipping than rounded edges. Use care with pots and pans around edges. If a chip does occur it is probably something we can repair during a service call.
