Refinish Pool Decks, Driveways and Patios with DCI Concrete Overlay
When we were first approached by this homeowner, we couldn’t believe the condition of their outdoor concrete, particularly the drive and walkways. Gray and black concrete paint applied less than two years previous was peeling off everywhere in a most unattractive way.
The homeowner was remodeling their home and wanted to change the color scheme of their outdoor concrete to match the new facade. The contractor was given the task of removing the deteriorating concrete paint and select a new finish that would complement the future materials and color palette of the home.
The solution was to use DCI Concrete Overlay on the driveway, walkways, patio and pool deck but first the deteriorating paint had to be removed. Because of the project size (over 4800 sq. ft.) and stamped surfaces, chemical removal would be too costly and therefore, was not a viable option. The contractor opted instead for shot-blasting the concrete. The shot blaster, rented locally from an equipment supply, would both thoroughly remove the paint and mechanically profile the concrete for good overlay adherence.
The contractor sprayed a 1/16th inch primer coat of smooth gray overlay from a hopper gun to mask the existing concrete color and level out the surface. The homeowners chose two contrasting concrete pigment colors – Smokestack (230-5lb.) and Maize (550-1lb.). The smokestack color was sprayed down first using a spray shield to the borders and curbs followed by the lighter maize color. The color and texture of the overlay reduces glare, heat absorption and potential slip hazards when wet. The entire surface was sealed with a two-part acrylic urethane concrete sealer. Acrylic urethanes though more expensive are easy to apply and last longer on exterior applications than traditional solvent-based acrylics so the finish can be enjoyed for many years to come.
