Synthetic Deck Maintenance : Easy Care Tips for Flexiteek Decking

Proper synthetic deck maintenance is key to keeping your boat or outdoor space looking pristine, without the high upkeep required by natural teak.

A beautiful deck can instantly improve the visual appeal of any boat. But it isn’t just about the beautiful looks; sometimes it comes down to the maintenance being too much to keep on top of. An example of this is traditional teak, which requires constant sanding, scrubbing, and oiling to maintain its appearance year after year.

This is where Flexiteek synthetic decking stands out. Designed to look like real teak without the high-maintenance demands, Flexiteek offers a low-maintenance, anti-fungal, and environmentally friendly solution. Perfect for marine environments, outdoor entertainment areas, and high-traffic residential spaces, it combines long-lasting performance with visual elegance.

If you’re searching for easy-to-maintain synthetic decking, Flexiteek brings unmatched convenience.

Why Flexiteek Makes Synthetic Deck Maintenance Easy

We have designed our decks to save you time and provide you with hassle-free maintenance. This is something we are always innovating on. Flexiteek 3 has become one of the easiest synthetic teak options on the market to clean. No harsh chemicals or abrasive cleaners are required when cleaning your deck. Fresh water or pH-neutral cleaning products get off most spills. Unlike natural teak, Flexiteek can be safely jet-washed for those more stubborn stains.

Our decks are all manufactured with an anti-fungal agent. Built directly into the material formulation to prevent mould, algae, and mildew, which is a common issue with natural teak, especially in damp or shaded areas. This added anti-fungal protection ensures your deck stays cleaner for longer and reduces the need for intensive cleaning sessions.

Another standout feature of Flexiteek is its re-sandable surface. Minor scratches, scuffs, and wear marks can be easily removed without replacing entire planks. Allowing you to restore the deck to a like-new appearance and extending its lifespan so you don’t have to worry about long-term wear and tear.

Eco-Friendly Benefits for Synthetic Deck Maintenance

Sustainability is increasingly important to consumers, whether that is in their own homes or on their boats. This is why Flexiteek 3 was designed with this in mind. Not only is it made with a bio-attributed PVC, but it also supports more sustainable cleaning practices.

We recommend using pH-neutral cleaners, not only to protect your deck from issues sometimes caused by alkaline or acidic products. But also, to reduce environmental impact. pH-neutral cleaning agents are safer for aquatic environments, such as plants and wildlife. Cleaning your deck shouldn’t harm surrounding ecosystems; using a neutral product helps protect marine life. This is also another reason we produced Flexiteek 3 to be cleanable with just water to not only to save you the hassle but to protect marine environments for years to come.

Our mission, even back in 2000 when we established Flexiteek, was to reduce the reliance on natural teak forests and provide an alternative that looks as beautiful but also offers a long-lasting, low-maintenance alternative. Natural teak forests are home to a wide range of wildlife, including endangered species such as tigers, elephants, and hornbills, all of which depend on healthy forest habitats. By choosing synthetic decking that requires minimal chemical use, boat owners not only help protect marine environments but also the forests traditionally harvested for teak.

Flexiteek’s durability also contributes to sustainability, our deck that lasts for many years, meaning fewer replacements, less waste, and reduced resource consumption throughout its lifetime, all reinforcing the environmental benefits of easier, low-impact cleaning.

Maintenance Tips for Longevity

All products last longer with proper care, and Flexiteek is no exception. This is why we created our 5-step care guide to help users maximise the lifespan of their Flexiteek synthetic decking. We developed a straightforward 5-step care guide. These steps are designed to tackle everything from everyday dirt to tougher stains, ensuring your deck remains safe, attractive, and long-lasting.

1. Rinse with Clean, Fresh Water
Begin by washing the area to remove loose dirt, dust, and salt. Regular rinsing prevents build-up and maintains the surface texture.

2. Apply Diluted pH-Neutral Detergent
Use a gentle, pH-neutral detergent on the affected area. Allow it to sit for no more than a few minutes, especially for difficult spills like fuel or oil. This helps “lift out” the stain without damaging the deck.

3. Use a Scotch-Brite Pad
For stubborn patches, scrub lightly with a Scotch-Brite pad, always working in line with the grain.

4. Use a Pressure Washer
A pressure washer can be used for deeper cleaning, provided it is kept at a safe distance and set to moderate pressure.

5. Sand the Affected Area
If marks persist, a light sanding will refresh the deck’s appearance. Flexiteek’s resandable finish makes this process quick and efficient.

Protecting Your Flexiteek Deck: What to Avoid

There are also easy things to do to protect your deck further, such as avoiding placing hot pans, BBQs, or any heated items directly on the surface. This is simple to overcome by using mats or trivets to prevent heat-related marks or distortion. You can also prevent dents or marks in the surface of your deck by using protective pads under furniture with narrow legs and avoiding concentrated pressure wherever possible. Additionally, avoid dragging items such as furniture and coolers, as these could leave scuff marks. Lift items when moving them, and if marking occurs, it is simple to remedy using a Scotch-Brite pad or light sanding to restore the finish.

Practical Benefits for Users

Flexiteek offers long-term value and convenience with its built-in anti-fungal protection and a slip-resistant texture. This keeps outdoor and marine areas safer while requiring minimal upkeep. Its ability to be resanded means long-term aesthetic appeal without expensive refurbishment.


Flexiteek combines low-maintenance care with a beautiful, teak-like appearance. Making it an ideal solution for anyone seeking durable, eco-friendly synthetic decking.
