What is the Caulk Yield for Teak Deck Caulking?

Our product specialists hear this question about caulk yield multiple times each business day:

How many cartridges of caulking should I buy? 

This question about our high-performance SIS 440 Teak Deck Caulking is our most common.

The answer: Caulk yield is dependent upon seam depth and width as well as user technique, and the package size.

SIS 440 TEAK DECK CAULKING

SIS 440 is available in two packaging sizes:

Cartridge – 10.3 oz (305 ml) and Foil “Sausage” – 20 oz (592 ml)


Award-Winning SIS 440 Teak Deck Caulking

LINEAR CAULK YIELD

We calculated the linear caulk yield (in feet and meters) to help boat owners, builders, and repair technicians. Then we created easy-to-read tables. These amounts include a waste factor of 25%.


IMPORTANT: The linear feet or linear meters yield per package varies by user’s technique. New users commonly caulk too heavily on a first job. It takes practice to develop the skill of seam filling.

Proper “spooning” technique is critical to ensure seams are adequately filled with SIS 440 Teak Deck Caulking as shown in this demonstration

Remember that caulking is not only decorative but has multiple functions:

  1. Seals the deck to prevent liquids from penetrating the sub-decking area
  2. Flexes and contracts with deck movement
  3. Functions in all temperature ranges
  4. Resists degradation by chemicals and UV light

Further, SIS 440 Teak Deck Caulking is an award-winning caulk and a proprietary formulation. When we couldn’t find a product that met our needs for constructing and repairing decks, we developed our own formulation.

How To Properly Prepare & Re-Caulk a Teak Deck Seam Part 2 of 2
By Anella Alcott April 11, 2025
If you're planning to get a new deck on your boat, and you've chosen teak, a composite deck, or a cork alternative, this guide will walk you through the full process, from digitization and manufacturing to final installation so you’ll know exactly what to expect from start to finish. TEAK DECKS Digital Templating The first stage involves one of our technicians digitially templating the area using the latest in precise measuring technology. Our team digititally templates vessels all around the world. Engineering Our experienced designers are masters of creating beautiful and technically precise decks using CAD construction program, importing data provided by our digital templating team. Our designers’ exceptional ability to create visual symmetry ensures impeccable finishes and beautiful aesthetic decks. Manufacturing TDS panels are manufactured in our factory utilizing jigs that are adjusted to conform to the vessel’s shape. Teak planks of the required thickness and width are carefully hand inspected, scrutinizing each plank for grain orientation, mineral deposits, or imperfections such as a small knot. The planks are placed into the jig in such a way that the finished deck will have a uniform butt joint pattern. Creating a Watertight Barrier A phenolic or fiberglass backing is securely vacuum bonded to the teak, using our own epoxies that guarantee durability, flexibility, strength and reliability. The exceptional bonding strength, ensures your deck stands the test of time. After the epoxy cures, the newly formed panels are removed from the jig, and the seams between the planks undergo routing, cleaning, and caulking. Margin Trim Once the caulking is cured, the final step involves laying out the teak deck and laying all the margin trim. Upon completion, the finished deck undergoes a thorough quality inspection, ensuring it aligns precisely with the template. Transport & Installation The finished deck panels are placed in custom-made crates and then shipped and installed worldwide. Prior to the arrival of the new deck, the old deck is removed. Our installers inspect for any issues such as water intrusion, delamination, or corrosion on the vessel’s surface. If such issues are found, the areas are repaired before the new deck is installed. Caulking & Sanding Once the deck has been bonded to the vessel, it is time to caulk using our own proprietary, UV, and chemical-resistant caulking TDS SIS-440. After curing, the deck is then ready to be sanded. The entire deck is sanded with 36 grit to remove excess caulking, followed by 60 and 80 grit to enhance the look of the deck. COMPOSITE DECKS Digital Templating The first stage involves one of our technicians digitially templating the area using the latest in precise measuring technology. Our team digititally templates vessels all around the world. Engineering Our experienced designers are masters of creating beautiful and technically precise decks using CAD construction program, importing data provided by our digital templating team. Our designers’ exceptional ability to create visual symmetry ensures impeccable finishes and beautiful aesthetic decks. Manufacturing Every composite decking panel is custom made to perfectly fit the areas to be covered. The panels are delivered with completed seam pattern, sanded and ready to be glued down on most structural surfaces. In the case of SeaSole, the deck is installed using the “peel and stick system”. We use a combination of our TDS bedding and bonding adhesive, along with TDS two-part, flexible epoxy fitting glue, to secure the panels in place. The caulking in the seams is our TDS proprietary patented filler, an enduringly elastic, solid rubber polyurethane joint sealant. Our team will first carry out an inspection of the boat to identify the best application method for each area. Quality Control Once the caulking is cured, the final step involves laying out the composite deck and building all the margin trim. Upon completion, the finished deck undergoes a thorough quality inspection, ensuring it aligns precisely with the original template. Installation The finished deck panels are placed in custom-made crates and then shipped and installed worldwide. Prior to the arrival of the new deck, the old deck is removed. Our installers inspect for any issues such as water intrusion, delamination, or corrosion on the vessel’s surface. If such issues are found, the areas are repaired before the new deck is installed.

Everything you need to know about cork decks As the industry and yacht owners move towards sustainable decking options, we have recently begun working with cork. This decision has been driven by the increasing demand from environmentally conscious customers . As more people prioritize eco-friendly choices in their purchases, cork has emerged as an ideal decking material. Known for its sustainability and numerous environmental benefits, cork offers unique characteristics that not only provide practical advantages but also contribute to a reduced environmental footprint . This makes cork a compelling choice for those looking to make greener decisions. TDS is a distributor for Navicork by Amorim , the world leader in the cork industry , which is leading the marine revolution with cork decks that champion sustainability. With more than 150 years of history, Amorim has made an unparalleled investment in research, innovation, and design, developing a portfolio of products and solutions that set the standard for environmentally responsible decking . Why is cork so environmentally friendly? UNESCO recognizes cork oak forests as one of the 36 most crucial ecosystems globally, highlighting their environmental significance. Cork is one of the most sustainable resources in the world and remains the only truly carbon-negative product on the market. Eco-Friendly & Carbon-Negative One tonne of cork absorbs about two tonnes of CO₂ while producing only 1.6 tonnes during processing. Harvesting cork does not require felling the tree , allowing forests to continue absorbing carbon dioxide. The bark regenerates , ensuring a sustainable and renewable material for generations to come. Lightweight and Durable Cork is significantly lighter than traditional decking materials, 2 to 5 times lighter than teak, reducing overall vessel weight and fuel efficiency. It is highly resistant to wear and tear , making it suitable for high-traffic marine applications. Superior Thermal and Acoustic Insulation Low thermal conductivity (0.065 W/mºK) minimizes condensation, reduces energy loss and keeps decks cool underfoot. The closed-cell structure of cork dampens structural noise , reducing onboard sound levels and acoustic performance. Comfort & Safety Cork’s soft, velvety texture provides superior underfoot comfort , reducing fatigue during long periods on deck. Its natural non-slip properties enhance safety, making it an excellent choice for marine environments. It’s splinter-free and reduces impact injuries compared to traditional hardwood decks. Design Flexibility & Aesthetic Appeal Available in various textures, colors, and patterns, cork decking can be customized to match the design vision of any vessel. Offers a unique aesthetic while still delivering the premium look and feel desired. For more information check our cork decking section
