Kraken Bond Pestblock Spray Foam Sealant 2-Pack - Paintable Gap Filler

In this review the Kraken Bond Pestblock Spray Foam Sealant 2-pack is examined as a practical solution for home sealing tasks; it is aimed at DIYers, handymen, and light contractors who need an easy-to-use, expanding foam that fills gaps, cracks and penetrations. The single biggest reason to buy is its straightforward dispensing with the included gun and cleaner kit, which makes application neater and more controlled than spraying straight from a can, and customers consistently note the product's solid functionality and value for money.

Key Features

• Easy dispensing: The can is designed for use with a foam gun applicator to give controlled, precise application for gaps and cavities.
• Single-component polyurethane: Ready to use out of the can and self-expanding to fill irregular voids without mixing or added materials.
• Environmentally friendly propellant: Formulated without harmful propellant gases to be safer for the ozone layer.
• Temperature guidance: Best performance at about 68F with effective use between 41F and 86F, so it can be used in most seasonal conditions.
• Versatile applications: Suitable for sealing window and door frames, wall holes, electrical outlets, pipes and other common penetrations.
• Paintable finish: Dries to a surface that can be trimmed and painted to blend with finished surfaces.

Who It's For

This product is best for homeowners and maintenance workers who need a straightforward expanding polyurethane foam for routine sealing jobs around windows, doors, pipes and electrical boxes. The included gun and cleaner make it a good choice for users who prefer cleaner application and some measure of control over bead size and placement.

It is less suitable for users who require professional-grade firestop or structural foams with specific certifications, or for very large commercial insulation projects where bulk supply and specialized materials are needed. Those users should look for industry-specific sealants designed for large-scale installations.

Pros & Cons

Pros

• Included gun and cleaner help produce neater, more accurate application than can-only sprays.
• Environmentally friendlier propellant formulation that avoids ozone-harming gases.
• Works across a wide temperature range and performs best when cans are near 68F.
• Good value for a two-can pack and praised by customers for functionality and quality.

Cons

• Durability and foam texture received mixed feedback from some customers, so finish quality can vary by application technique.
• Requires acclimation to room temperature in cold climates for best results, adding prep time.
