Deck-O-Foam Joint Filler 1/2" x3 1/2" | 50' | 1413035

The Deck-O-Foam Joint Filler (Part #1413035) is a flexible closed-cell polyethylene expansion joint filler designed for pool decks, concrete slabs, coping joints, and other expansion/isolation joint applications. Sized at 1/2 inch thick x 3-1/2 inches tall x 50 feet long,  (sold by 50ft increments), this foam strip installs between concrete sections to absorb expansion and contraction movement while helping prevent cracking and joint failure. Its pre-scored removable top strip creates a clean, uniform sealant reservoir for deck sealant application, reducing the need for routing or sawing. Manufactured from non-absorbent, UV-stable, chemical-resistant closed-cell foam, Deck-O-Foam is built for long-term durability in exterior environments and is commonly used beneath pool deck joint sealants such as Deck-O-Seal.

Highlights

• Expansion Joint Protection: Absorbs slab movement between pool decking and coping to help prevent cracking and structural damage.
• Pre-Scored Tear Strip: Removable top section creates a uniform channel for deck sealant installation.
• Closed-Cell Polyethylene Foam: Non-absorbent material resists water intrusion and maintains long-term compressibility.
• UV & Chemical Resistant: Designed for outdoor exposure and compatibility with harsh poolside environments.
• Flexible 50' Roll Format: Easily bends around curves and contours for straight or freeform pool deck installations.
