Dap Inc 18268 Asphalt Roof Sealant 10.1 Oz Black

Product Description

The DAP INC 18268 is a black asphalt-based roof sealant designed to form a durable, watertight seal on exterior roofing surfaces. Dispensed from a 10.1 oz cartridge, it is formulated to resist sagging and cracking after application, making it well-suited for repairs that need to hold up under weather exposure. Roofing contractors and general contractors use this sealant for small-scale repair and maintenance tasks where a flexible, adhesive-grade asphalt compound is required. The black finish blends with common roofing materials for a clean, finished appearance on completed repairs.

This sealant is applied in residential and light commercial roofing applications. Primary uses include sealing roof flashings at penetrations and transitions, spotting damaged or lifted shingles, and repairing minor roof leaks before they develop into larger moisture issues. It is typically used as part of a preventive maintenance program or as an emergency repair measure during a service call. The cartridge format is compatible with a standard caulking gun for controlled, single-handed application at the roof surface.

Installation Notes

Application should be performed by a qualified roofing contractor or tradesperson familiar with roofing safety requirements. Clean and dry the substrate thoroughly before applying sealant to ensure proper adhesion. Avoid application during rain or when surface temperatures are below the product-rated range, as moisture and cold can compromise adhesion. Follow applicable building codes and manufacturer surface-preparation guidelines for best results.
