Petra Max Rock Glue is a professional-grade landscape adhesive designed to hold loose ground cover materials in place, preventing the displacement, scattering, and erosion that wind, rain, and foot traffic cause over time.
WHAT IT WORKS ON
Small gravel, pea gravel, decorative pebbles, stones, decomposed granite, mulch, wood chips, bark, shells, sand, pine straw, hay, straw, and leaf piles. The formula is strong enough for heavy materials like gravel and pebbles when applied in a thick, saturating layer.
HOW TO APPLY
Apply to dry, debris-free surfaces. For lightweight organic materials such as mulch or pine straw, a standard spray layer is sufficient. For heavier stone and gravel, apply a thick layer so the adhesive penetrates between pieces. The blue tint helps you track coverage and fades as the glue dries clear. Visible setting occurs within about half a day. Full cure continues over the following 24 hours.
DILUTION
This is a concentrated formula. Apply as-is for the strongest bond, or dilute with water for broader coverage on lighter materials.
WHERE TO USE IT
Pathways, walkways, planting beds, garden borders, slope stabilization, around trees and shrubs, rock gardens, decorative stone features, playground borders, French drains, and erosion-prone zones.
