Packaged in a convenient 10.1 oz tube, the formula delivers a flexible, waterproof bond that can stretch up to 600 % without losing adhesion, making it ideal for repairing cracks, gaps, and joints that experience movement or vibration.

Formulated with a premium elastomeric polymer blend, this sealant offers superior tensile strength of 600 psi, ensuring long‑lasting durability even in high‑traffic areas. Its paste‑like consistency allows for easy application with a standard caulking gun, while the fast‑acting cure time of approximately 30 minutes enables rapid project turnaround. The sealant is fully waterproof, resistant to mold and mildew, and can be painted within two hours, providing a seamless finish that matches surrounding surfaces.

Designed for versatility, the DAP 18715 adheres to a broad spectrum of substrates, including tile, pipe, countertops, windows, doors, sinks, tubs, walls, and gutters. This universal compatibility eliminates the need for multiple specialty products, simplifying inventory management for both professional contractors and DIY enthusiasts. The white color blends discreetly with most interior finishes, while the compact 4 × 2 × 11.4 in. packaging ensures easy storage and handling.

Each tube contains 10.1 fluid ounces of premium sealant, and the product is sold as a 2‑pack, providing a total of 20.2 oz for larger projects or repeat use. The packaging includes clear labeling of safety information, usage instructions, and a QR code linking to detailed application videos, ensuring users have all the resources needed for a successful seal.

Manufactured by DAP Products Inc., a trusted name in the adhesives and sealants industry, this product meets rigorous quality standards and is backed by a comprehensive warranty. The sealant complies with industry regulations for indoor air quality and is free from hazardous solvents, making it a safe choice for residential and commercial environments alike.

Usage

When applied to tile grout lines, the sealant expands to fill micro‑cracks, preventing water infiltration that can lead to mold growth. Its waterproof nature makes it an excellent choice for sealing around kitchen and bathroom fixtures, such as sinks, tubs, and shower enclosures, where constant exposure to moisture is expected.

For exterior applications, the sealant performs reliably on gutters, window frames, and door jambs, where temperature fluctuations cause material expansion and contraction. The 600 % stretch capability accommodates these movements, reducing the likelihood of future cracking and the need for costly repairs.

Professional contractors often use this sealant for joint sealing in commercial construction projects, including concrete slab joints and expansion joints in flooring systems. Its quick cure time allows for rapid progression through project phases, while the paintable surface ensures a uniform appearance after finishing work.

DIY homeowners benefit from the easy‑to‑apply paste consistency, which can be smoothed with a finger or a caulking tool for a clean line. The product’s low odor and non‑solvent base make it comfortable to work with in confined spaces, and the clear instructions on the label guide users through proper surface preparation and application techniques.

In addition to traditional sealing tasks, the DAP 18715 can be used for creative projects such as sealing decorative mosaic tiles, repairing cracked plaster, or even as a flexible adhesive for lightweight decorative elements. Its versatility and reliable performance make it a go‑to solution for a wide array of sealing challenges.

FAQ

Can the sealant be applied in cold temperatures?

Yes, the DAP 18715 sealant can be applied in temperatures as low as 40 °F (4 °C). However, curing time may be slightly longer in colder conditions. For best results, ensure the surface is clean, dry, and free of dust before application.

Is the sealant safe for use around food preparation areas?

Absolutely. The sealant is formulated without hazardous solvents and meets FDA‑approved standards for indirect food contact. Once fully cured and painted, it creates a non‑toxic barrier suitable for kitchen countertops, backsplashes, and other food‑related surfaces.

How long does it take for the sealant to become fully waterproof?

The sealant develops a waterproof film within 30 minutes of application, achieving full cure and maximum water resistance after 24 hours. This rapid waterproofing allows you to resume normal use of the sealed area quickly.

Can I use the sealant on outdoor projects?

Yes, the DAP 18715 is designed for both interior and exterior applications. Its UV‑resistant formulation and ability to stretch with temperature fluctuations make it ideal for sealing windows, doors, gutters, and other outdoor joints.

What is the recommended method for removing excess sealant?

While the sealant is still wet, excess can be wiped away with a damp cloth. For cured sealant, gently scrape with a plastic putty knife and clean the residue with a mild detergent. Avoid using abrasive tools that could damage the underlying surface.
