Step 1 - Pre-Wash

  1. Start with Polarshine® Marine Deep Clean.
  2. Dilute the oxalic acid-based detergent based on the level of soiling, using a ratio between 1:3 and 1:10. Apply the solution with a spray bottle.
  3. For tougher cleaning, use a scrub brush to enhance the detergent’s effectiveness.
  4. Let the solution sit for 5 to 10 minutes. If working outdoors, adjust the timing based on temperature and weather conditions. Rinse thoroughly with water.
  5. Don’t forget to flush the trailer as well to ensure a complete clean.

Step 2 - Wash

  1. Use Polarshine® Marine Boat Wash to clean and prepare your boat’s surface.
  2. Dilute the product between 1:30 and 1:100, depending on the level of soiling. Apply the solution with a spray bottle.
  3. For stubborn dirt, use a scrub brush to boost the detergent’s cleaning power.
  4. Allow the detergent to neutralize the surface by leaving it on for 1 to 5 minutes. Then, rinse thoroughly with water.
  5. Dry the surface using a microfiber cloth.

Recommendation: If the surface is in poor condition, sanding is advised. For surfaces that are only faded, polishing alone will suffice.

Step 3 - Sanding

Sanding is optional if the surface is in poor condition.

  1. Sand the surface using a Mirka® DEROS with Abralon® 2000 grit and water. Recommended speed: 6000–8000 RPM. Abralon® sands effectively as long as it produces a “foam” during sanding.
  2. Clean the surface between steps before switching to 4000 grit. This helps to extend the life of the sanding disc.
  3. Wipe the surface with a microfiber cloth to prepare it for polishing.

Step 4 - Polishing

Polish on a dry surface.

  1. Use a Mirka® PS 1437 and a lambswool pad Pro.
  2. Apply Polarshine® 10 polish to the surface using the polishing pad. Recommended speed: 900–1100 RPM.
  3. For light-colored surfaces: Use Polarshine® 10 with a yellow lambswool pad Pro.
    For dark surfaces: Follow up with Polarshine® 5 and a yellow waffle polishing foam pad to remove holograms.

Step 5 - Cleaning

  1. After polishing, wipe off any polishing residue with Polarshine® Marine Final Finish.
  2. Wet the surface and apply Polarshine® Marine Shield to the sponge and the area to be coated. NOTE! The surface must be moist.

Step 6 - Coating

  1. Let it work for a moment. You will notice when the coating starts to retract.
  2. Rinse off excess coating using a pressure washer.
  3. Dry the surface with a microfiber cloth.
  4. Allow the coating to cure for at least 12 hours (dry, at +5°C to +25°C).
  5. The coating provides protection for one boating season.
