Two coats are generally better than one If the deck has been properly cleaned, it should absorb the first of stain well in to the wood. By applying a second, light coat of material, you will fill up the cell structure of the wood (kind of like topping off the tank) and the project will last longer.
How long do you wait before applying a second coat of stain?
For a deeper color and sheen, wait one hour and apply a second coat. After 1 hour, the surface is dry to the touch. Wait overnight before subjecting the wood to normal use. Optional, for additional luster or sheen a clear protective finish can be applied.
Can I apply a second coat of stain a day later?
Yes you cannot apply now but you can apply a light coat after a light cleaning 6-12 months later. It is normal that you have to redo every 2 years and other semi-transparent brands will not last any longer. They all fade.May 6, 2015
