GENERAL CARE AND PROTECTION OF CONCRETE COUNTERTOPS AND OR SINKS
SEALER INFORMATION FOR COUNTERTOPS AND SINKS
The sealer we use is in accordance with USDA regulations 9 CFR, Section 416.4 and the Food Safety Inspection Service’s “Sanitation Performance Compliance Guide”. It is a Water- Based, Non-Emitting Penetrating Sealer, with a high resistance to etching from acidic products such as wine and lemons. The sealer is Ultra – Low VOC, similar to water.
For countertops indoors reapplication of sealer is recommended every 5-10 years. No stripping is required.
For countertops outdoors continued maintenance and reapplication of sealer is recommended every year or depending on use. No stripping is required.
Please call Concrete Works for further information.
For several weeks after applying the sealer you may notice the concrete darken in areas where water or liquids contact the surface. This is normal as the cross linking of the sealer continues. Darkening of the surface is not an indication that the sealer is not working; in fact, it is a normal reaction as the sealer continues to cure.
In certain cases hazing/efflorescence of the finish may occur in the first couple of months after installation as moisture inside the concrete continues to escape. This is easily buffed off without the creation of dust. It can also be removed using a soft abrasive cleaning sponge such as Scotch- Brite Non-Scratch Scrub Sponge and water, then dried with a micro fiber cloth afterwards. Further efflorescence may occur after buffing/ scrubbing and follow up may be necessary. Please call us if rebuffing is needed.
As with all natural, handmade materials slight variation in the finish and color is possible and is not considered a defect. All of our products are warranted against structural cracking. Hairline cracks can form and are not to be considered a defect.
