As the before photos illustrate this deck was mildew and algae covered and hadn’t been sealed in nearly eight years. Lime’s preparation process consisted of sanding the entire deck including railing spindles, caps, skirting, floors, and stairs. Lime sanded the deck to remove the discoloration (esthetics) and loose particle (promote maximum product penetration and adhesion) represented in the mildew and algae. Lime then used a deck restore product designed to restore the natural vibrancy of the redwood tones. If that wasn’t enough, Lime removed all deck screws and counter sunk a new set of deck screws to ensure the decks integrity. Finally, lime used an oil based (most water repellant) stain to seal the deck from water penetration and sun break down.
