Applying excess is needed to deal with shrinkage, but over and under doing it is all too easy. Very durable stuff, it would outlast your teak. Review: Horrible product - The product was impossible to dispense. It was practically dry and I threw it away. I will never purchase this product again. There is a local marine store, I will pay more but at least they will stand behind what they sell. ## Features - HIGH QUALITY MARINE POLYMER || 10oz cartridge of gray caulk - One-part silane polymer - Forms a solid rubber compound with highest rated UV resistance - Excellent resistance to chemicals - Superior temperature stability - Easy to sand - Improves project turnover time - FLEXIBLE & PRIMER-FREE || Thixotropic paste which does not drip or sag - Easy to work because it stays flexible - One-step process saves application time - No solvents - Environmentally friendly - Safe for work environment - More economical - Less waste - FIRST-CLASS APPEARANCE || Use in seams from 3 to 10mm wide to achieve first-class appearance - Seam depth should be equal to or greater than the seam width - Caulk must fill to bottom of seam - Bond-breaker tape recommended for seams of 5mm (3/16”) or deeper - Full depth caulk seams extend teak deck life - CURE TIME || Cures to provide better adhesion, longevity and appearance as compared to polysulfide, polyurethane and MS polymers - Curing time for SIS440 Caulk in gray is 12 days - This is based on seams ¼”x¼” (6.4mmx6.4mm), larger seams may require additional time - PROPERTIES || Available in black and white - Product has 18-month shelf life from date of manufacture (printed on bottle) - Meets Federal Specifications & ASTM C920 - Manufactured in an ISO 9001 facility ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08KGGZWN2 | | Best Sellers Rank | #246,594 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #617 in Adhesive Caulk | | Brand Name | Teakdecking Systems | | Color | Gray | | Customer Reviews | 3.5 3.5 out of 5 stars (12) | | Full Cure Time | 12 Days | | Initial Hardening Time | 12 Days | | Item Form | Paste, Strip | | Item Weight | 0.94 Pounds | | Liquid Volume | 10 Fluid Ounces | | Manufacturer | Teakdecking Systems | | Material Type | Silane Polymer | | Maximum Gap Fill | 10 Millimeters | | Surface Recommendation | Window | | UPC | 853367004132 | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Teakdecking Systems - **Color:** Gray - **Full Cure Time:** 12 Days - **Item Weight:** 0.94 Pounds - **Liquid Volume:** 10 Fluid Ounces ## Images ![10oz Marine Caulk Cartridge, Gray - SIS440 - Premium Quality - for Teak Deck Seams - Provides First Class Appearance - UV & Chemical Resistant, Non-Corrosive - Image 1](https://m.media-amazon.com/images/I/618-wfC1KKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ works but a bit expensive *by G***P on February 5, 2025* It shrinks somewhat so a second application may be needed to fill in valley.
