I use Restore-A-Deck kit in 2016 and it ended up removing some of my existing TWP 100 (stained in 2014) so I had to sand everything down and start from scratch instead of just a maintenance coat.
I only have time and energy for maintenance coat this year, (2017). I have cleaned everything with soapy water and it looks good except for 2 issues.
1) I have some small black streaking on the top handrail. Can I use safely use this to clean and brighten without removing the existing stain which has otherwise held up well over the last year?
2) i had an offset umbrella out all year and during cleaning noticed the area under it has not faded at all, I do not want to strip or sand the whole deck for this 2ft by 2ft area, any ideas? I can put umbrella back in same place to hide it if only way to lessen the difference is strip and/or sand.
The Gemini Kit is designed for prepping when reapplying the TWP, not just for general cleaning as it may remove some of the current stain. This is normal for prep.
Best to put the umbrella back in the same spot if not reapplying the TWP.
