Can I make a custom design for my synthetic teak deck?
When selecting a teak deck, it's crucial that it complements the style and character of your boat or vessel. Marine Deck Pro allow you to develop any design or concept you envision. Interested in a particular pattern, a distinctive color combination, or other creative ideas? This is achievable with synthetic teak decks.
Do synthetic teak decks discolour?
Some synthetic teak decks may experience discoloration over time, particularly when exposed to direct sunlight and other environmental factors. This issue is typically linked to the quality of the materials used and may occur more frequently with less expensive options.
At Marine Deck Pro, we exclusively use Permateek synthetic decking, which maintains its color even after years of exposure to the elements, ensuring the deck remains visually appealing without concerns of discoloration.
Are synthetic teak decks slippery when wet?
Safety is always a priority when choosing decking, especially when it gets wet from rain or waves splashing over. Luckily, synthetic teak decks have a non-slip surface that minimizes the risk of slipping.
How does the weight of synthetic decking compare to traditional decking?
Synthetic teak decks typically weigh less than natural teak decks. This reduction in weight can enhance vessel stability, as a lighter deck positively influences the vessel's overall balance and weight distribution.
replacing an existing deck with a synthetic teak deck.
A synthetic teak deck serves as an excellent substitute for your current deck, but the old deck needs to be removed first. Our team can handle this removal charged on an hourly basis.
If you're looking to save on costs, you have the option to remove it yourself. After the old deck is removed, the new synthetic teak deck can be installed as needed. Nonetheless, it's recommended to get professional advice to determine the best approach for your specific situation.
Is synthetic decking scratch and stain resistant?
Synthetic teak decks are crafted for durability and are fairly resistant to scratches and stains. Typically, stains can be cleaned with warm water and soap, while more persistent stains may require light sanding for removal.
Minor scratches can often be sanded out, but if there are deep scratches, a repair might be the only solution.
Is it possible to repair damaged synthetic teak deck?
Certainly, repairs to a synthetic teak deck are feasible. However, depending on the nature and extent of the damage, a subtle difference in appearance may be visible after the repair.
Although the result is often close to the original, it is good to realize that seamless integration can sometimes be challenging. It is therefore advisable to seek professional advice on the best approach and expected outcome of a repair when damage occurs.
Can you notice a difference when walking on natural teak and synthetic teak?
Walking on natural teak and synthetic teak is often described as being quite similar by most people.
Both materials offer a firm grip and are comfortable for standing or walking. Although there might be minor differences in texture, these are generally insignificant when it comes to comfort. However, it's important to consider the location of use and where the boat is stored, as synthetic teak can become hot when exposed to direct sunlight.
How are synthetic teak decks attached?
Synthetic teak decks are attached using a specialized adhesive formulated to create a strong and waterproof connection. This adhesive guarantees that the deck firmly adheres to the surface, making it resistant to everyday stress and weather conditions. Once bonded, the deck's edges and seams are meticulously sealed. This sealing process with a sealant stops water from penetrating beneath the deck and also gives it a polished appearance. The comprehensive gluing and sealing process ensures that the deck is not only firmly attached but also shielded from moisture and weather over an extended period.
Can synthetic teak decks be used indoor?
Synthetic teak decks can be used for indoor applications. While they are commonly linked to the outdoor areas of ships and boats, their characteristics and finish make them just as appropriate for interior spaces.
How to clean synthetic teak?
To effectively clean and preserve the quality of synthetic teak, it is advisable to use cleaning products specifically formulated for this material. Various companies offer a range of specialized cleaning products for synthetic teak decks.
Are synthetic teak decks susceptible to algae growth?
Synthetic teak decks are crafted to withstand algae and fungus growth due to specific treatments and the natural characteristics of the materials used.
This results in reduced maintenance needs in areas prone to algae issues, ensuring the deck's longevity.
Nevertheless, it is still recommended to maintain the deck's cleanliness to avoid dirt buildup and potential algae breeding spots.
How long does synthetic deck installation take?
The duration required to install a synthetic teak deck can differ based on several factors.
The deck's size, larger decks naturally take longer to build and install.
The complexity of the design chosen can greatly influence the installation time. Intricate patterns or specific alterations may extend the installation period.
However, synthetic teak decks generally offer a faster and more efficient installation than natural teak.
Are synthetic teak decks suitable for all boats?
Synthetic teak decks are adaptable to all types of vessels and can be fitted on numerous types of boats. From sailing boats to luxury motor yachts and everything in-between, synthetic teak fulfills all demands.
How to Compare Teak and Composite Decking
Teakdecking Systems (TDS) offers legally sourced superyacht-quality Southeast Asian teak and high-end polyurethane composite decking. Boat owners often ask us how to compare teak and composite decking. Rarely is there one factor alone to consider. All these must be weighed: appearance, durability, maintenance, safety, cost, installation, deck weight, environmental impact, and surface temperature. Here, we look at each factor to compare teak and composite decking.
APPEARANCE
TEAK is traditional, classic, and timeless. It has a “warm” feeling, especially when it is new or after sanding. Sunlight ages it to a silvery patina. Superyacht quality teak has tight grain quarter-sawn teak from old-growth Burmese logs and is highly durable. So, many consider it a status symbol. Some enthusiasts even consider it “obligatory” for wooden boats.
COMPOSITE decking provides freedom of design to create unique decking—contemporary or traditional. The color and texture can be customized, and the color stays true for an extended time. Unlike teak, butt joints are not necessary. Like teak, it does not absorb water.
DURABILITY
TEAK is exceptionally durable and can last 15-20 years or longer with proper care. See our blog on “How to Extend the Life of a Teak Deck”. Its wear is dependent upon usage and desired look (or sanding frequency). Teak is rot-resistant; its natural oils fight water penetration, as well as algae and mold. Red wine or fish blood can and will stain teak, but can easily be removed. Sunscreen and potato chip oil will penetrate the wood (and can stain too). TDS Sealer and Protector can safeguard the surface. Soiled or damaged teak battens or trim boards can be sanded, repaired, or replaced.
COMPOSITE decks can last 20 years or more. This is achieved with well-installed, properly maintained, high-quality materials, such as the polyurethane of TDS Composite Decking. These materials resist shrinkage and adhesive failure when installed properly. In contrast, lower quality composite decks (EVA and PVC materials) can last as few as three to five years.
Properties vary by material type. In general, composite materials are stainproof from many fluids, but not red wine and fish blood. Quite often, the decking discolors (fades) over time even though some materials have UV inhibitors to reduce the effects. Some inferior composite materials will shrink, and adhesive failures can occur. Repairs and refits typically require trained professionals.
MAINTENANCE
TEAK is gently cleaned by scrubbing across the grain with a medium scrubbing pad (3M “red”) and a one-part cleaner (ECO-100 & ECO-300). For more aggressive restoration, a sand-out may be needed. NOTE: Power washing or vigorous chemical cleaning (two-part cleaners) removes softwood, leaving hard ridges that hold dirt and contaminants. Harsh cleaning methods can also harm the surrounding gel coat or paint and stainless steel.
COMPOSITE is easy to clean with water, soap, or by power washing. Skin oils or scuffs show immediately on some light-colored materials but are cleanable.
SAFETY
TEAK is a natural, non-skid surface, wet or dry, and COMPOSITE materials have the same properties.

COST
TEAK supply of legally sourced old-growth trees is diminishing; timber costs are steadily increasing. So it is tempting to consider lower-priced plantation teak as an alternative. This is not recommended since it is less durable (more softwood) and the much wider grain gives in an aesthetically unsuitable appearance. If well-maintained, teak will significantly enhance a vessel’s resale value.
COMPOSITE materials are 30-50% less expensive than teak, according to many industry publications. However, quality can vary widely depending on the manufacturer. Installation costs vary too. High-end materials with professional installations can be priced slightly less than teak.
INSTALLATION
TEAK decks can be installed by a moderately skilled carpenter for most projects. TDS or a qualified boatyard should install more complex projects (e.g., lots of trim and hatches). This is especially true when performing fastenless installations, i.e., vacuum bagging and barring. Some small areas can be DIY. Repairs to teak can require the replacement of batten(s) or margin trim.
COMPOSITE is best installed by a moderately skilled carpenter. The fairing of the subdeck must be virtually perfect for the thin panels (e.g., 6mm). Improper installation can cause “bubbling” by adhesive gassing or trapped air. This problem occurs when cure times are not met, or when the “down” pressure is removed too soon.
Note for DIY: Achieve the best results by having the manufacturer pre-cut the decking panels to address the many styling details. Understandably, the best areas for DIY are small, like an interior sole or footrest. Some materials are “peel and stick.” As previously mentioned, a replacement may be needed in 3 to 5 years from installation.
DECK WEIGHT
TEAK weight varies with the thickness; the most common thickness is 14mm with an estimated weight of 2.2 lbs/sq. ft (10.7 kg/sq m). For a slight weight reduction, the teak thickness can be reduced to 10mm or 12mm.
COMPOSITE weights vary by product type (EVA, PVC, etc.); however, most are lighter than teak.
ENVIRONMENTAL IMPACT
TEAK must be legally-sourced from sustainable forests. (Note: TDS timber is 50+ years old.) The use of elephants for harvesting and transporting logs helps protect endangered species. It also aids new growth teak, with less impact on the land. 90% of a cut teak tree is used in multiple industries for decking, furniture, windows, doors, etc. Teak is renewable and recyclable.
COMPOSITE decking may have oils and chorine used in its production, and hazardous by-products are produced. Some materials are not recyclable and not as “green” as desired. It is best to check with the product manufacturer for more information.
TEMPERATURE
TEAK has the coolest surface, in general. The R-value (insulation) and sound suppression are very good. Further, below deck temperatures are more stable due to teak’s insulation properties.
COMPOSITE PVC decks can get as hot as 150°F (65.5°C). Lighter-colored materials have the coolest temperatures, and darker colors can become too hot for bare feet. (TDS firmly recommends light colors.) The lowest density material will have the lowest heat. Composite decking will cool when wet.
SUMMARY
Owners have the freedom to decide on decking, and these are 3 KEY TIPS to compare teak and composite decking:
Consider the boat type and the amount of maintenance required.
Research all materials and select one based on performance and personal taste.
Purchase within budget.
Cost-effective
One of the five advantages is the price and the wide choice of color. Topdek 2G has an authentic appearance due to the wood grain and color variations visible in real wood. The material is available in twelve colour combinations, from new to weathered. The price difference of synthetic deck planks is significant compared to the scarce teakwood grown on special plantations.
Crafted synthetic teak deck
Making a synthetic deck requires the same processes as a wooden deck. Using a mold, the planks are custom-made and attached to each other using vinyl welding techniques, making these connections stronger than when glue is used. The PVC material can be perfectly processed into characteristic curved lines with king planks and herringbone or a straight layout without king planks if you want to give the boat a more modern look.
Topdek 2G is not only for new-build ships but also a perfect solution if you want to renovate a ship’s deck. The material is expertly glued to the ship, neatly finished waterproof, and possibly equipped with bumpers. Finally, the deck is sanded, highlighting the beautiful grains. The material gets a lifelike teakwood appearance, a feast for the eyes.
Lower in weight
Topdek 2G is 32% lighter in weight than comparable (1G) synthetic deck material, resulting in significant fuel savings. The material is an excellent choice for performance yachts, powerboats, and multi-deck passenger ships, but also for sailing yachts, sloops, or motor yachts.
Durable Topdek
Due to its low weight, Topdek 2G ranks among the top of the most sustainable teakwood deck replacements. In the production of Topdek 2G, phthalate free plasticizers are used, and the product complies with REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) guidelines. Moreover, the product is 100% recyclable.
As it is installed waterproof and resistant to both UV and saltwater, you can sail worry-free for many years. If there is minor damage, it is easy to repair.
Easy to maintain
This brings us to the last major advantage of synthetic teak, easy maintenance. Because no one wants time-consuming tasks. With the sealer, the deck is protected against dirt, making it easier to remove. For cleaning, use the Topdek Synthetic Teak Cleaner. This is a multifunctional biodegradable cleaning agent that cleans all washable surfaces safely and efficiently. The cleaner does not affect cured paints, synthetics, rubber, textiles, or metals and ensures that the surface becomes antistatic, which is important when using electronic equipment such as fish finders and navigation tools.
Topdek was founded in 2007 out of a passion for water sports. The first decks we delivered at that time are still a feast for the eyes and require little maintenance. As a distributor of Topdek 2G synthetic teak deck, we work with a wide network of dealers and reputable shipbuilders who expertly install the deck.
