Making Concrete Countertops Look Like Granite

Updated February 21, 2017

Concrete, like granite, is a type of masonry commonly used for countertops. One of the advantages of concrete is that it is much less expensive than natural stones such as granite and marble. While concrete is sleek and modern and growing very popular as a kitchen countertop, if you have your heart set on the look of granite, a substitute simply won’t do. Before you junk your existing concrete countertops, however, consider a very realistic painted finish that may satisfy your longing for granite without the cost.

Mix two parts of water and one part of degreasing cleanser in a plastic bucket. Dip a cloth into the solution and clean the countertops well; rinse them by wiping them with a cloth dampened with plain water. Let the countertops air dry completely.

Line the edges of the counters where they meet the sink, cabinets, walls, and any other structures with painter’s tape to protect these surfaces. Cover large items and the floor with dust sheets to prevent paint splatter. Cover backsplashes completely with overlapped pieces of painter’s tape, if necessary.

Pour the black primer into a paint pan; dip a paint roller into the primer and apply it evenly all over the top of the counters. Change to a sponge brush and apply the primer to the edges and trim of the countertops. Let the primer dry six hours.

Sprinkle the included minerals onto the sponge from the kit. Gently pat the minerals onto the primed surface with the sponge. Try to keep the application natural-looking and random.

Let the counters dry two hours once the minerals have been applied. Examine the counters for any areas where the surface is now roughened. Use 320-grit sandpaper to very lightly sand away these coarse places.

Apply the clear topcoat all over the countertop just as you did the primer, using a paint roller and a clean sponge brush. Let the topcoat dry eight hours. Re-examine the counter for uneven spots and sand them away with fresh sandpaper.

Coat the counter with a second application of the clear topcoat. Be sure that you are happy with the final appearance. Wait 48 hours before using the counter.
