How to Protect Hulls From Lake Algae

Algae is a common problem for boat owners. Moisture encourages mold and algae to accumulate on the boat's exterior, especially if it spends the majority of the time in the water. Algae can badly stain a boat's exterior and damage the paint job on it. Protecting a boat's hull from algae growth should be a priority for any boat owner. Fortunately, algae protection is not difficult but it does require some regular effort.

Things You'll Need

Pressure washer
Anti-algae agent
Paint roller

Instructions

- 1
  Rinse any existing algae off the boat hull with a pressure washer. The combination of water pressure and heat will eliminate the existing algae.
- 2
  Apply an anti-algae agent to the hull with a paint roller. Allow the chemical to set for the amount of time recommended by the instructions and then rinse it off. This helps prevent further algae from growing on the boat.
- 3
  Avoid driving the boat through any algae patches in the water because algae can attach to the hull and start spreading if not removed.
- 4
  Remove the boat from the water if it isn't being used regularly.
