Water beads up and runs off my porch, sidewalk, and steps like rain runs off the body of a freshly waxed car. Water doesn't soak into the concrete anymore like it did before I applied Siloxa-Tek 8500. It beads up and runs off, or, sits there until it evaporates. Anyway, why would you want to mix it stronger (more Siloxa-Tek and less water)? It's already expensive enough mixing it as recommended!! **Q: If only half is used, how long is the remaining half good for?** A: It depends on how it is stored **Q: Can a driveway treated with siloxa-tek 8500 be resurfaced later using a cement resurfacing product (rapid set new crete)?** A: Why waste your time and money treating a surface you plan to repair. Do it right. Fix the surface then seal it ## Frequently Bought Together - Siloxa-Tek 8500 Ultra Concentrate - 1 Gallon (Makes 5 GALLONS) Penetrating Concrete Sealer Water and Salt Repellent.
