3. Preparation and Mixing
Proper preparation ensures optimal performance and longevity of the mulch glue.
Required Materials
- PetraMax Mulch Glue Max Concentrate
- Water
- Sprayer (PetraTools sprayer recommended for best results)
- Measuring cup/container
- Stirring tool (if mixing in a separate container)
- Protective gear (gloves, safety glasses)
Mixing Instructions
The PetraMax Mulch Glue is a concentrate and must be diluted with water before application.
- For spraying, mix 1 part mulch glue with 1/2 part water.
- For pouring, mix 1 part mulch glue with 1/5 part water.
- Shake well before use to ensure uniformity and prevent nozzle clogging.
Example Coverage (for spraying 1 quart glue + 1/2 quart water): Covers approximately 50 sq. ft. per coat.

4. Application Guidelines
For best results, apply the mulch glue in completely dry, warm conditions (above 50°F / 10°C) with humidity below 70%. Avoid rain for 48 hours after applying.
Step-by-Step Application
- Prepare the Area: Ensure the base mulch/stones are clean, dry, and free of dust, mud, or oil. Remove any weeds.
- Rake/Turn Mulch: Rake or turn the mulch to ensure it is completely dry before applying. This also helps expose untreated mulch for subsequent coats.
- Apply First Coat: Spray an even, thin coat over the mulch without oversaturating.
- Drying Time: Allow the first coat to dry for at least 24 hours before applying additional coats.
- Apply Additional Coats: For maximum strength and hold, apply 2-3 thin coats. Rake/turn mulch between coats to ensure even coverage. A thick layer may result in white/blue residue.
- Final Drying: Let the treated area dry undisturbed for 48+ hours after the final application.

Coverage
The entire 32oz bottle covers approximately 50 sq. ft. when applied in three coats. Large mulch/bark will require more coats and may have less coverage area.

6. Troubleshooting
Common Issues and Solutions
- Mulch Not Holding / Moves Easily:
- Ensure the mulch was completely dry before application.
