10 Best Mulch Glue 2025 in the United States

The Lockdown Sticky Mulch Glue by Petra is designed to offer strong adhesion for landscaping materials like pea gravel, pine straw, and more. One of its standout features is its high coverage; a single gallon can cover up to 128 sq. ft., making it cost-effective for large areas. This product is weather-resistant, ensuring that your mulch stays in place through storms and heavy winds, which is ideal for maintaining a neat garden bed with minimal maintenance.

Additionally, the glue is eco-friendly, being non-toxic and safe for kids, pets, and plants, which makes it suitable for both residential and commercial use. It also dries clear, which helps maintain the aesthetic of your landscape. The application is straightforward and quick, as it doesn’t require waiting between coats and only needs a simple 1:1 dilution to be effective. However, it's noted that the glue is not ideal for high-traffic areas and works best on fully dried mulch.

It boasts a long-lasting hold of up to 2 years, although a light annual reapplication is recommended to maintain its performance. The product is manufactured in the USA by Petra, a family-owned company offering 24/7 customer support. The drying time is fairly fast, making it convenient for DIY enthusiasts. One minor drawback might be the weight and dimensions of the container, which could be cumbersome for some users to handle. Also, since it's a concentrated solution, precise mixing is required for optimal results. This product is best suited for those looking to achieve long-lasting, low-maintenance landscaping without the need for frequent reapplication or worry about safety concerns.

PetraMax Mulch Glue is a highly effective solution for securing various landscaping materials like mulch, wood chips, shells, sand, pine straw, and even small gravel and pebbles.

Its concentrated formula provides great value, as one gallon can be mixed with water to produce a larger volume of glue, making it cost-effective for larger projects.

The glue dries clear and fast, typically within 12 to 24 months of coverage, though the drying time might vary depending on environmental conditions.

The product is easy to apply by spraying, although users need to mix it correctly with water to achieve the best results. While the glue is versatile and works well with various materials, its performance might vary with very heavy or large rocks, and multiple applications might be necessary to ensure strong adhesion.

It adheres well to different surfaces, helping keep your landscaping neat and stable.

This reduces the need for constant touch-ups, saving effort and money over time.

Its water-based formula is non-toxic and safe for pets and the environment, although direct spraying on plants should be avoided to prevent yellowing.

Applying the glue is simple—just mix with water and spray—while testing a small spot first is recommended to check how it reacts with your materials and sunlight.

This product is a smart choice for anyone wanting to keep landscaping materials firmly in place without frequent maintenance, although it may not replace mulch entirely. Its size and coverage make it suitable for medium to large outdoor projects, including pathways and patios. Users should be mindful that direct plant contact during application could cause some discoloration, so careful use is advised.
