Decks
1. Keep the deck surfaces clean and dry.

PPG Wrought Iron Breakthrough Acrylic is the standard top coat.
Allow seven days to fully cure. Avoid getting paint into lockdowns and down edges between decks.
Note: The deck edging cannot be painted.
4. Do not use oil-based cleaning products or stains on the hardboard surface.
5. Do not wax or polish the hardboard surface.
Drapery Closures
1. Drapery sections may be washed or dry-cleaned.
2. Drapery sections are attached with hook and loop strips, to allow easy removal for cleaning.
