An excerpt from an email...
"Prior to the work done by Pressure Pros, the deck was solid - no creaking, minimal gaps between the deck boards, and smooth, solid board surfaces. After the job was completed, the entire deck creaks, the surface of the boards is rough (possibly from sanding or powerwashing), has developed cracks in some areas (both at the ends and in some cases in the middle), there is warping and cupping, and gaps have developed where the boards shrank significantly."
This was ipe deck #200+. Cabot's ATO, sodium hydroxide strip, brighten, application of Armstrong semi trans.
Deck was exposed all winter. You gotta love some people. How would you handle this?
