3 Reasons Why Marine Sandblasting Is Ideal for Boat Restoration


When taking care of your boat, finding the right techniques for getting your boat’s longest life will save you a small fortune. Whether you are a hobbyist wondering how to restore a boat or a captain of a ship, you want to ensure that the job gets done in time, with precision, and on budget.

Sandblasting is an effective means for stripping paint off of your marine vehicle. The process is best used as a preventative measure. Here are three reasons why sandblasting is a useful step in boat restoration.

1. Marine Sandblasting Removes Rust

Marine Sandblasting is a method that removes all layers of paint, including the primer, from your boat’s surface. By removing layers of paint, you can expose any remaining rust.

For older boats that have been around for three decades, this would be the first step in fixing metal surfaces. Doing so decreases the chances of having to do more serious repairs later on.

2. Boat Sandblasting Removes Old Paint

Much like stripping down the rust on your boat’s metal surface, boat sandblasting can also remove old paint. Whether you are revamping your fiberglass boat completely or in one area, sandblasting is excellent for keeping your marine vehicle’s integrity before re-painting.

It’s recommended to only sandblast on fiberglass boats because chemicals such as this can otherwise damage the boat.

While sandblasting is usually used to strip paint and remove rust, it can also be an effective preventative maintenance method. By blasting away at the surface of your boat’s metal parts, you are preventing rust from setting in and staining areas that appear to be okay at first glance.

3. Sandblasting Preps the Surface for New Paint

Sandblasting before painting can save you time and money in the long run. Your boat will be more durable, and you will not have to deal with peeling or chipping paint later on down the road.

Sandblasting strips off your marine vehicle’s old paint’s top layer, which exposes the new surface underneath. When this process succeeds, it leaves a smooth finish with a better bond when repainted. It can also remove old paint from the shell, allowing your boat to have a fresh start.

If it is too late for sandblasting and you need paint right away, that’s fine. But painting over pre-primed surfaces in your boat maintenance plan is better.

Since the paint will already adhere to the surface, it will not be much different than painting over bare metal. Sandblasting first will rid imperfections and ensure an even coat of paint on your marine vehicle.

Boat Restoration Is Worth Every Penny

Sandblasting is an option that you may want to consider before you begin painting as part of your fiberglass boat restoration. There are other alternatives to sandblasting, such as stripping your boat with chemicals.

Yet, if you have a metal hull, you should avoid chemical stripping because of the rusting effects it may have. This causes more harm than good and will be more expensive in the long run if your boat starts to rust again after restoration.

Plan ahead for stripping and blasting so that there is no room for error when it comes to marine vehicle maintenance.
