Description

America's Most Trusted Mulch Glue

Zero toxins. 100% permeable. 6+ months of hold. Made in the USA.

Zero Toxins.

No VOCs. No harsh chemicals. No warning labels longer than the instructions. Safe for pets, kids, plants, and soil once cured.

Rain Drains Right Through

100% water-permeable. Creates a flexible mesh, not a solid seal. Rain, irrigation, and snowmelt drain right through.

Apply Once. Forget About It.

One application holds up to a year through the worst weather, heaviest foot traffic, and wildest pets.

Made in the USA. Not Imported.

Most mulch glues are manufactured overseas with no safety data. Ours is formulated, tested, and produced in the USA.

Easy Application

Clean it. Spray it. Forget it. That's the whole process.

Step 1

Clean Your Mulch Bed. Make sure mulch is dry

Step 2

Spray three coats. Use the included pump sprayer with a cone or flat nozzle. Let dry 2–4 hours between coats. About 20 minutes total.

Step 3

Cure & Enjoy Keep dry for 24–36 hours. Then walk on it, play on it, let the dogs run on it. Your rock isn't going anywhere.

Step 1

Clean Your Mulch Bed. Make sure mulch is dry and spread evenly at 1"–1.5" depth.

Step 2

Spray three coats. Shake the bottle. Pour into your garden sprayer. Apply one even coat. Lightly rake and turn the mulch. Apply two more coats and tamp down.

Step 3

Let It Cure Keep area completely dry for 24 hours. Then let the rain come. Let the dogs run. Let the kids play. Your mulch isn't going anywhere.

Great Product

Great Product. Easy to use, great directions, and so far holding everything in place.

No More Mulch Washout!

I recently refreshed the mulch in my front flower beds, but every time it rained a little bit, mulch ended up scattered across the driveway. To fix the problem, I tried a concentrated Lockscape Glue, mixing it in a garden sprayer and applying it over the entire area. After letting it dry overnight, the mulch looked unchanged—after this past storm, it stayed exactly where it was.

It’s now been about a month, and even after heavy wind, storms, and using a leaf blower, nothing has shifted. I also appreciate that it’s plant-safe. Considering the durability and cost, it feels like a worthwhile purchase.

Great Product!

Excited to have a product that is safe for kids to still be able to play freely and keep the house looking nice!

Keeps weeds down too

Wasn't expecting this but the glue seems to help with weed prevention. I think it seals the surface so seeds can't get through. Been three months and way fewer weeds than usual.

Mixed results

Some areas great, some not so much. Not sure what I did differently. The flat sections are perfect but the sloped area needed extra coats.

EVERY CONCERN ANSWERED

Does mulch glue actually hold, and how strong is the bond?

Yes. Lockscape RTU penetrates between mulch pieces and bonds from the inside out. Two coats create a hold that stands up to rain, wind, washout, and regular yard use without shifting.
