Wet sanding is the process of using sandpaper to remove paint or varnish from a boat. The process can be done by hand or with a machine, and it is typically followed by polishing the boat’s surface.
Wet sanding can be a more gentle process than dry sanding, and it is less likely to damage the boat’s gel coat finish. Furthermore, this type of sanding is much less dusty, making it a better option for indoor work.
Tools and materials to wet sand the boat
- Waterproof gloves, safety goggles, and a dust mask
- Bucket, sponge, and garden hose
- Polishing compound (optional)
- Wax (optional)
- Putty knife
- Liquid Gelcoat
- Drop cloth or tarp
- Sandpaper (coarse, medium, and fine grit)
A step-by-step guide to wet sand your boat
Step 1: Prepare the area
Before you start wet sanding, you will need to prepare the area where you will be working. Cover any nearby surfaces with a drop cloth or tarp to protect them from water and sanding debris.
Remove any loose paint or varnish from the boat’s surface with a putty knife.
If the boat has a gel coat finish, use a liquid Gelcoat stripper to remove any wax or polish on the surface.
Step 2: Prepare a bucket of water
Fill a bucket with clean water and set it next to your workspace. You will need to dip your sandpaper in the water frequently to keep it from drying out.
Step 3: Put on gloves and safety gear
Put on a pair of waterproof gloves to protect your hands from the water and sandpaper. Wear a dust mask to avoid breathing in any sanding debris, and put on a pair of safety goggles to protect your eyes.
Step 4: Begin wet sanding
Dip your piece of sandpaper in the bucket of water and then begin sanding the boat’s surface.
Start with coarse-grit sandpaper and work your way up to medium or fine grit as needed.
Sand in long, even strokes until you have removed all of the paint or varnish from the boat’s surface.
Step 5: Rinse off the boat’s surface
Once you have finished sanding, rinse off the boat’s surface with a garden hose. This will remove any sanding debris and allow you to see how much paint or varnish you have removed.
Step 6: Dry the boat’s surface
Dry the boat’s surface with a clean towel. If you missed any areas while sanding, go back and redo the parts.
Step 7: Apply polish or wax (optional)
If you want to polish the boat’s surface, apply a polishing compound with a clean cloth. If you want to wax the boat’s exterior, apply a coat of wax with a clean cloth.
Allow the polish or wax to dry for the amount of time specified by the manufacturer before buffing it off with a clean cloth.
