I have a second story porch constructed of fiberglass. concrete will not stick because fiberglass is not porous. Do I need to use epoxy and is their a spray to texture the floor and then paint it?
You can epoxy or use an epoxy that has a texture within it. For choices, you may have better luck going through a marine supply store rather than a home store. Or, check with a paint store and tell them what you are trying to do.
