Yes. If you have sealed it before, use the same base coating; oil, xylene or water-based acrylic, that you used for the sealer after washing the surface with TSP to dull the surface. If you're not sure of what is used on your patio, use an oil-based paint for best results. If you're in an area where you can not purchase oil-based coatings, use a water-based alkyd or take your chances and use a 100% acrylic floor coating.
