Note: Always follow the manufacturer’s recommendations for the application and the safety of applying their sealing products.
Using a 3 to 4 inch brush, apply the sealer over the entire concrete countertop, do not forget the exposed edges. You cannot apply too much sealer, having puddles of the sealer on the countertop is not detrimental to the finished product, however, you must complete the application of the sealer in one continuous process or joint lines between sealer applications may be obvious.
Allow the sealer to remain on the countertop for approximately 5 minutes. Then using a rag that has been moistened with the sealer, wipe any remaining sealer from the surface of the concrete.
Repeat Step 2 twice more. In other words, apply 3 coats of the sealer to the concrete countertop.
Wait 1 hour and then wipe on a coat of mineral oil using a clean rag.
Applying the wax to the concrete countertop
Apply a layer of the carnauba wax to approximately 4 square feet of the concrete countertop using a clean cloth.
Note: There is a wax available that is specifically formulated for kitchen countertops and is FDA approved. It is a combination of carnauba wax, beeswax and mineral oil and is available from Expressions-LTD.
Wait 2 or 3 minutes and then, using a clean cloth, wipe off the excess wax from the concrete countertop.
Immediately buff the area that you have waxed.
Repeat Steps 1 through 3 until the complete concrete countertop, do not forget the exposed edges, has been covered in wax and all of the wax has been thoroughly buffed.
Note: Waxing a sealed countertop (either tropical or penetrating) once a month is the best way to build a protective layer and maintain a great-looking finish.
