A Comprehensive Guide on How to Fiberglass A Deck If you're thinking of renovating your deck, there are a lot of materials you can use, but if you want a sturdy and long-lasting deck, fiberglass may be an excellent option for you, as fiberglass in conjunction with resin is a durable material that can withstand harsh environments and protects your deck from water, and in this guide, we will provide you with valuable information on how to fiberglass a deck.
-Stir Sticks -Fiberglass rollers and Paintbrushes- Aluminum rollers work great for flat surfaces and help work the resin into the fiberglass. Bristle rollers are good for releasing the bubbles trapped in the resin. Corner rollers are great for concave surfaces or corners. Paintbrushes also work to apply resin to the fiberglass. -Squeegee and spreaders- Also great for applying and spreading resin. -Fillers- You can buy a premade fairing putty to fill holes, cracks or any other imperfections. You can make your own by adding various fillers such as glass bubbles or fumed silica to your resin to create a putty. -Sandpaper- various grits -Safety equipment- Resin has fumes and is hazardous. You will want to wear gloves, a respirator or mask and some safety goggles. -Acetone- To clean tools and for surface prep. -Putty knife (optional) -Caulk (optional) Prepare the Surface The next step is preparing the deck surface, which will ensure proper fiberglass adhesion. Start by cleaning the surface to get rid of any debris, dirt, and dust. You can also use a power washer. It is imperative that the surface is dry and free of moisture before beginning. If there is any moisture left on the surface, the resin will not adhere well and the fiberglass and resin will delaminate. Sand the surface with 80-grit sandpaper to scratch all existing coatings on the deck's surface, providing resin, something to grab onto. Use a vacuum cleaner or blower to remove any dirt or dust from the sanding process. Then clean with acetone. If there are any holes where nails/screws were used, cracks or imperfections, use a premade fiberglass putty or one you made on your own using fiberglass fillers and resin. Remember to wear protective gloves, respirator or mask when working with resin and fiberglass. You will need to add MEKP catalyst to the fairing putty or resin at 1% to 2% by volume depending on ambient temperature and desired working time. Use a putty knife to smooth out the surface when applying. The spaces between the deck and posts can be caulked before starting. Let it cure.
   
Preparing Resin Surface and Applying Gel Coat The next step is to sand down the rough edges with sandpaper, making the surface smooth and even. Once everything is completed, it's time to gelcoat your fiberglass deck. People typically go for a white, grey or beige color gel coat for their deck. Adding a polyester gel coat enables the fiberglass to be fully protected from UV rays, saltwater, and other exterior elements. Two layers of gel coat are recommended. The first layer should be without wax. That is so it will cure with a tack and will not need to be sanded before adding another layer. When working with multiple layers, you only want the final layer of gel coat to contain wax. The wax in the final layer raises to the top, inhibiting air and cures to a hard tack free finish. Measure out the gel coat in a mixing cup and add MEKP at 1 to 2% by volume. Mix well. Apply evenly over the surface. Let cure and then add a second layer. Once everything is cured, you can sand any imperfections or uneven spots. Conclusion: Fiberglassing a deck can seem like an intimidating task, but it is a great DIY project. The process is relatively simple and can be completed within a short time frame, depending on the size of your deck and the ambient temperature. The benefits of adding fiberglass and resin to your deck are worth all your time, effort, and expense. Fiberglass decks are durable enough to withstand weather conditions. Remember to follow these steps, starting with assembling materials, preparing the surface, applying the fiberglass and resin, sanding, and gel coating the deck. Following these steps, you'll have a sturdy deck that will last for years to come.
   

Fiberglass Deck
AUCKLAND FIBERGLASS DECK SYSTEM
 

A fiberglass deck is a durable, waterproof surfacing system made from layers of glass fiber matting saturated with resin, topped with a protective gel coat, creating a seamless, leakproof, and long-lasting surface ideal for areas needing high water resistance like coastal homes or decks over living spaces, offering superior longevity over wood but with a higher upfront cost. It's tough, resists rot, UV, and heavy traffic, and requires minimal maintenance, with professional application creating a solid, custom-fit shell.

In summary, fiberglass decks are a familiar sight in Auckland, but the trend is toward newer, more advanced materials, with many contractors ready to help you transition to a more durable and attractive sundeck.

 

Fiber-reinforced glass
Residential sundecks in Auckland are constructed from wood. When exposed to the adverse weather conditions, decks’ surface and bearing structure can deteriorate and require costly repair. Fortunately, quality of sundecks can be achieved with the waterproof, seamless, and durable fiberglass membrane application.

Fibre-reinforced glass, commonly known as fiberglass, is a composite material used often on sundecks, roofs, walkways, door surrounds, bathtubs, boats, and water storage tubs. History of fiberglass use on sundecks for more than a half of century in New Zealand proves outstanding track record. Homeowners often demand fiberglass membrane when rebuilding their deck, because of their positive experience in the past.
 

Fiberglass Deck Resurfacing
Fiberglass deck resurfacing creates a durable, waterproof surface by laminating layers of fiberglass mat and resin over a solid substrate, often plywood, to repair, strengthen, and beautify decks, requiring thorough prep like sanding, cleaning, and repairing damage, followed by precise application of resin, mat, and a final gelcoat or topcoat for a long-lasting finish.

It's ideal for converting plank decks, fixing soft spots, or adding UV protection, but requires careful attention to drainage and structural integrity, especially with rotted wood.
