Caulk Colors for Synthetic Teak Decking & Custom Matching
DuraTeak – alternative teak decking with standard and fully customized caulk colors.
Modern synthetic teak decking is not just about plank geometry and surface texture. The caulk color between the boards has a huge impact on how realistic and high-end the finished deck looks. At DuraTeak we offer a set of proven standard colors, but we also specialise in custom caulk color matching so that boat owners and yards can get exactly the deck appearance they want.
For authenticity, black caulk remains the classic choice and is still the most commonly used color, just like on traditional wooden teak decks. Over the last decades, improvements in caulking and grout materials have introduced additional options such as white, grey and beige. Because these colors also work very well with real teak, we include them as standard caulk colors in the DuraTeak palette for alternative teak decking.
Authentic teak look with flexible caulk design
As a premium synthetic teak decking alternative, DuraTeak is designed to resemble real teak wood as closely as possible. This realistic effect is not only a question of the board surface but also of the quality, texture and color of the seams. Caulk lines frame every plank and strongly influence whether a deck looks like genuine teak or like a generic plastic surface.
At the same time, we know that many projects demand more than a “standard” look. Some owners want subtle seams that match their hull color, others prefer a strong contrast line to highlight the deck layout. Because our profiles are not co-extruded with fixed seam colors, we can react quickly and cost-effectively to custom design ideas. This flexibility allows us to deliver unique deck designs without compromising on technical performance.
In-house extrusion and full RAL caulk color options
As an extrusion facility, we produce both the DuraTeak synthetic teak decking profiles and the matching caulk materials in-house from high-quality plastic granules. This gives us full control over color, hardness, gloss level and overall material quality. We supply different industries with profiles and seams in a wide range of sizes, colors and material grades, all tailored to the specific application.
- Standard black, white, grey and beige caulk colors for classic teak deck designs
- Custom caulk colors based on the full RAL color scale
- Adjustable hardness and gloss to match project requirements
- Consistent color and quality across larger production runs
With caulk colors selectable from the entire RAL range, our customers are never limited to a narrow standard palette. Whether you need to match an existing deck, a brand color or a special design feature, DuraTeak can provide a precisely matched caulk color that enhances the visual impact of your synthetic teak decking.
Our goal with DuraTeak is to deliver a high-quality synthetic teak decking system that not only performs well on the water, but also looks perfectly integrated into the design of your boat. In an upcoming article we will present the available deck board color options in more detail and show how they can be combined with our caulk colors for a fully customized deck layout.
