1) QUESTION:
Do I need to reapply after rainy weather? Or is the product embedded enough to still be working on lifting the oil stain? You mention to have patience, but I am not sure if that is referring to allowing it weeks to work (through sporadic rainy weather) or if I should reapply.
ANSWER:
SealGreen Gray-Out Waterless Oil Cleaner work slowly cleaning oil stains. Once you apply the product it will permanently stick in a few days to the concrete depending on the humidity in the air. It is required that when you apply the product the concrete surface must be dry.
If you apply the product and it rains and washes away some of the product because it has not completely adhered to the concrete surface. Please wait for the surface to dry completely and the apply more Gray-Out to the areas where you can see the oil stain.
Once the product has completely adhered to the surface regular rains will not remove the powder.

QUESTION
If I should reapply, how often should I be reapplying the product and when (ex: after each rain fall? etc.)
ANSWER:
You only need to apply more product to areas that over time expose oil stains. Just treat does exposed areas. When an area is exposed after several weeks means that the powder has clean as much oil as possible and needs addition product to continue with he cleanup of the oil.
