The process of cleaning and prepping boat bottoms would include the following: When the boat is hauled out the first task, if necessary, is to scrape off any heavy marine growth and barnacles with flat blades. The next step might be pressure-washing the bottom which will clean off surface scum. Traditionally, the next step would be sanding the hull which is the most destructive part of the process in hull cleaning. It is a very difficult manual task and virtually impossible to keep from sanding and gouging into or through the gelcoat. Once the gel coat is damaged, water can get between it and the fiberglass. The hydraulic pressure from the water then begins to cause blisters, fractures, and delamination of the gelcoat. The original gel coat is smooth in texture and serves as a protective barrier of the underlying fiberglass. A quick coat of bottom paint and the owner is totally unaware of the condition of his hull because of the cosmetic effect of the fresh paint.

So what is Soda Blasting? This is an air pressure driven, non-destructive method of cleaning and paint stripping on fiberglass, wood, steel, aluminum and other substrates. Soda blasting is fast, cost effective and flexible. As it relates to the specific task-boats that have layers upon layers of bottom paint, soda blasting will remove the layers of old paint without harming the gelcoat. Most boats can be soda blasted in just one day with a much more thorough outcome. Areas around through-hulls, running strakes and prop pockets and be cleaned like never before. Soda blasting will prepare the surface for gelcoat repair, possible application of an epoxy barrier coating and application of new anti-fouling bottom paint. This will ensure years of coating life service and better operating performance because of reduced weight and less drag. In summary, Soda blasting will support and sustain good hull integrity while improving performance in speed for sailing and motor craft with lower fuel cost.
