Spots on deck.

[A-OK Pressure]

Home owner called me said that there where white spots on his deck from the houswash I did for him. I went and had a look and sure enough the F-13 I used on the gutters left white spots on his deck. He had just stained it with Armstrong stain. Do I have to strip the boards that have the white spots or can they just be stained over?
Thanks

Worst case scenario you have to strip the boards, but do this. Ask Bob what he suggests to remove it and just do it on the spots and then try and touch the stain up. Armstrong has good properties when it comes to the stain not matching up. It seems to blend in with itself pretty well. If you have to strip just strip the boards end to end with the stains on them and re stain. No need to re strip the entire deck and all.

Have you tried rinsing the spots? Its possible that the spots are actually white from the finish on the gutters. If so, they might simply rinse off. Just a thought.
