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. One of its major strengths is its strong adhesion strength, ensuring that materials stay in place and resist washouts from rain or disturbances from leaf blowers.

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. It is also non-toxic and safe for pets and plants, adding to its appeal for eco-conscious users. 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. PetraTools, the manufacturer, offers strong customer support and a satisfaction guarantee, which is a plus for those who may need assistance or have questions regarding the product.

The Lockscape Sticky Rock or Sticky Mulch Glue bundle by PetraTools is a comprehensive solution for landscaping needs. This bundle includes 1 gallon of concentrated glue and a high-quality PetraTools HD101 sprayer designed to distribute the glue evenly. One of the main strengths of this product is its adhesion strength, which is enhanced by the concentrated formula that can be mixed with water to create three times the glue of ready-to-use formulas. This ensures the mulch and rocks stay in place effectively, reducing washouts from heavy rain and preventing leaf blowers from displacing the mulch.

The glue dries fast and provides up to 12 months of coverage, making it highly weather-resistant and reliable throughout the year. Additionally, its eco-friendly formula is non-toxic, water permeable, and safe for pets and plants, which is a significant plus for users concerned about environmental impact. The ease of application is also noteworthy, thanks to the included sprayer with two nozzle options and a wide mouth lid for easy mixing.

On the downside, while the product is user-friendly and efficient, the initial setup might require careful mixing to achieve the best results, which could be a bit tricky for first-time users. Another potential drawback is the weight of the sprayer and glue bundle, which might be cumbersome for some users to handle comfortably. Despite these minor issues, this product is well-suited for anyone looking to maintain their garden landscape with minimal effort while ensuring long-lasting adhesion and eco-friendliness.
