One of the most commonly used solutions for filling the gap between kitchen counter and wall is caulk. This versatile material is a type of sealant that can be applied with a caulking gun to create a waterproof and airtight seal. It also comes in a variety of colors to match your kitchen's aesthetic. For best results, use a high-quality silicone or acrylic latex caulk, and make sure to clean and dry the area before application. Use a putty knife to smooth out any excess caulk and create a clean finish. With its durability and flexibility, caulk is a tried-and-true method for filling the gap between your kitchen counter and wall.1. Caulk: The Classic Solution

This not only helps to create a more durable seal but also reduces the amount of caulk needed, making it a cost-effective solution.2. Backer Rod: A Supportive Solution
