What is the Caulk Yield for Teak Deck Caulking?

  • Blog

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)

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.

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.
