Fiberglass cloth is a widely used material in boatbuilding. It is typically used to reinforce wooden boats, making them more durable and resistant to water damage. If you are planning to fiberglass your wooden boat, there are several things you need to know.
Firstly, fiberglass cloth is a type of reinforcing material that consists of thin strands of glass fiber. These strands are woven into a mat or fabric, which is then impregnated with a resin that hardens to form a strong, durable composite.
One of the most important things to consider when fiberglassing your wooden boat is the type of fiberglass cloth you use. There are many different types of fiberglass cloth available, but the most commonly used is 7628 fiberglass cloth. 7628 fiberglass cloth is a medium-weight cloth that is ideal for reinforcing wooden boat hulls.
When using 7628 fiberglass cloth, it is important to follow the manufacturer's instructions carefully. This will ensure that you apply the cloth correctly and that it adheres properly to the surface of your boat. Generally, you will need to sand the surface of your boat to create a rough, textured surface that the fiberglass cloth can adhere to.
Once you have prepared the surface of your boat, you can begin applying the fiberglass cloth. This typically involves laying the cloth over the surface of the boat and spreading a layer of resin over the top. You will then need to squeegee the resin into the cloth until it is evenly distributed.
As you work, it is important to avoid air bubbles, which can weaken the strength of the fiberglass surface. To eliminate air bubbles, you can use a roller or squeegee to apply even pressure to the surface of the cloth.
Overall, fiberglass cloth is a great way to reinforce your wooden boat and make it more durable. However, it is important to use the right type of cloth and to follow the manufacturer's instructions carefully to ensure the best results. If you are unsure about how to fiberglass your boat, it may be best to consult a professional boatbuilder to guide you through the process.
