Please note:

This table calculates the exact amount of caulk required to fill the seam. During the seam filling process, you will want to allow for leaving a slight “crown” on the seam to account for a slight reduction during the curing process, as well as the overage that occurs during spooning.

To calculate the amount of caulk you will need, we recommend adding 20 – 25% to these calculations to ensure you have adequate material for your project.

How to Inspect Teak Deck Caulking & Seams

July 3, 2024
Teak deck caulking and seam condition is a critical indicator of a boat deck’s quality. Inspecting the caulking and seams can determine the overall deck condition, teak deck thickness, and remaining life of the deck. MISSING OR DETACHED CAULKING  On a dry deck, examine the seams between the planks to look for missing or detached caulking. If no caulk seam failures are visible, wet the boat deck. As the deck dries, look for areas along the edges of the caulk seams that stay wet longer than the surrounding teak. This is where caulk failures may exist.

What is the Caulk Yield for Teak Deck Caulking?

July 3, 2024
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)

How to Recaulk Seams

July 3, 2024
“I’d rather burn my boat to the waterline before I recaulk seams again,” a boat owner said to our Sales Manager at a recent boat show. Then the boat owner laughed and said, “Of course, my family and I love the Hylas 54 too much to do this. But I sure did have some frustrations, largely my fault. It was my first recaulking job, and it was a big one with nearly one mile of seams.”
