How to Darken Flagstone | Homesteady
Test the penetrating sealer or stone enhancer on a sample piece of flagstone, if possible. If no sample pieces are available, test it first on an inconspicuous area of your installed flagstone. Allow the stone to cure for the specified time after the final coat, and then sprinkle water over the surface. On properly sealed stone, the water will bead up. If the sealer doesn’t perform as desired, test another small area using a different brand. Don’t treat your entire stone floor until you find a product that provides the color enhancement and stain protection you want.
