Applying burnish technique on boats has been acknowledged by many people because of its lustrous outcome. It helps to make the boat more striking. Why do you need to burnish the bottom paint?

How To Burnish Boat Bottom Paint – Step By Step

How To Burnish Boat Bottom Paint

Now that you know the good side of burnishing bottom paint, shall delve straight into the process of how it’s done. Well then, follow the process below to burnish the bottom of your boat effectively. 

Step 1: What You Will Need

For burnishing you will need cutting compounds (variants of sandpapers). As we are not talking about painting, let it be just the sandpaper. In the FAQ section below you can see how to do a paint job. 

Step 2: Mount The Boat On A Stand

Keep in mind that you are not gonna burnish a boat while it’s on water. Just like you paint the carrier by placing it in a stand. You should do it for burnishing as well. Get boat stands to support the weight of the boat and for easy access to the bottom surface. To know more about boat stands you can follow this link. 

Step 3: Work On A Smooth Hull

It is wise to burnish a clean surface. If the plane has excessive debris and residues you can cause damage while working the sandpaper. When the boat is done with paintwork, or you just want to burnish an existing paint, just get it out of the water and let it dry first. Wipe the surface with cleaners and wait for it to dry. 

Step 4: Wet Sand The Bottom And You Are Done

Remember that working with sandpaper on soft paint won’t work. If the paint you applied is known as hard paint, then you can burnish the surface with sandpapers. I request you to have different grits of paper with you. 

You will have to perform wet sanding, which means soaking the sandpaper with water or other cleaning agents and then giving it a swirl on the bottom surface. The best way to do it is to use a 400 grit sandpaper and gradually move up to 600, to attain a finer finish. 

If you find sandpapers are not giving you the desired shine. You can opt for bronze wool for a more lustrous outcome. Remember that if your boat has antifouling paint, you must be careful not to rub the surface too hard. Try to be gentle, as antifouling colors are on the soft side and might wear out with excessive rubbings. Keep the work going for as long as you don’t see a sheeny surface. 

If you successfully follow the four steps, you can now get your boat back on the water and see the difference yourself.
