Hello I stained my deck 3 years ago with TWP stain not sure what number. I think it is time to do it again but I am not sure should I only clean and brighten and reapply the stain? On the railing there are some black stripes not sure if did something wrong while applying the stain.[/quote]
You should be okay with using the Gemini Restore Kit and pressure washing for the prep.
Also in 2013, you ordered the 1530 Natural color.
