Mildew & Algae

This type of stain usually occurs in shaded locations where water puddles exist. If treated early, mildew and algae can easily be removed.

• Mix 50% pool chlorine to the water.
• Apply directly onto the affected area with a plastic sprayer or sprinkler can.
• Lightly scrub the chlorine solution over the affected area.
• Allow the solution to soak without drying.
• Rinse the area completely when the solution has stopped reacting.
• Squeegee or broom water from the deck.

Stubborn deposits require soaking with a more concentrated solution and moderate scrubbing.

• Apply a concentrated solution of citrus-based cleaner with sprinkler can.
• Spread the solution over the area with a deck broom.
• Allow the solution to soak without drying.
• Completely scrub the area.
• Rinse thoroughly with a high-pressure nozzle.
• Squeegee or broom off the water.

High traffic areas may require repeated applications for maximum results.

The best maintenance tip for black tire marks is to hose and clean the area on a regular basis to prevent a heavy build-up of rubber and asphalt residue. Other good cleaners that can be used include Simple Green, Nature’s Orange, Amway LOC or TSP.

• Freeze with dry ice or CO2 type fire extinguisher and chip off with a putty knife.
• Spray remaining residue with Disolvit or Goof Off.
• Scrape off with a putty knife.
• Clean area with citrus-based cleaner or equivalent.
• Rinse off any remaining residue.

Paint that is spilled or sprayed on Sundek should be quickly wiped up with a cloth. If the paint has dried, the affected area can be touched up with Sundek Finish Coat. Apply as you would water-based paint. Heavy paint-globs must be scraped off prior to applying the Sundek Finish Coat.

Do not use paint removers!!! These will cause damage to the Sundek finish.
