NorthRock Landscape Mulch Glue 5 Gallon – Pet and Plants Safe Rock Bond

FANTASTIC PRODUCT! IT ACTUALLY WORKS. I applied this to an area where I have decomposed granite (DG) to create a tropical/desert scene. I did this around September 2020. I felt I needed to do something as DG will spread its dust all over the place-even indoors. Also, erosion occurs due to slopes and rains. It is now July 2021 and the DG is still in tact, with a crusty top layer. The only place it broke down is where I broke it from a water spray or poking with garden tools. I DID apply two layers on the flats and three layers on the slopes. I did this because I wanted to make sure it would hold for the winter rains. We actually had a light rainy season, so a true test would be if we will ever get a rainy season again here in Sacramento. Plus, I felt I had to use it up due to its short opened shelf life. I am very pleased with its performance. A bit of advise would be not to apply it around trees and plants, as water rolls off this stuff. Compared to other available products locally, the coverage of Landscape Loc Mulch & Rock Bond is around FIVE times better! (Meaning it goes much further than the others, which means much less expensive). And, according to the label, lasts much longer, too! I think I will order another bucket for this season, just in case, but I probably don't need to this year.

I didn’t do a good job of compacting the soil underneath my fire pit area so I needed something solidify the gravel. This did exactly what I needed for my river pebble rocks. Used the entire 5 gallons on the fire pit which is about 190 sq ft. As you can see I also used some PermaSand for the retaining blocks and flag stones. We will see what happens over time and after some rain but i waited until the forecast showed several days of no rains and it’s very solid right now. You can still pull rocks up but this will allow foot traffic. It’ll also keep my dog and 7 year old from tearing up this area. The other impressive thing is that it’s kept the natural color of the rocks. It’s a milky white substance that clears within 5 minutes of applying starts drying. It doesn’t even appear to have anything on it. I tried a pump strayer at first for the first coat which was very slow and used a water can that came out a lot quicker for the second coat. Not sure which is better honestly. Overall, this was worth a shot over the other expensive solutions. Just go ahead and get the 5 gallon bucket if you have any question about how much.

Update 2 months after application: didn’t hold. Just didn’t. None of it. We used 4 gallons of it and it didn’t hold with the dogs & regular walking. This product would be great for an area that is hardly trafficked & just wanting a clean look all the time. If the area is trafficked at all, and the gravel is more than one layer deep (as it is recommended to be) then it doesn’t hold. This product would be great in a garden for mulch that isn’t walked on as well. Won’t buy again for the same purpose, but if needed for little projects like mulch, maybe. We have a lot of pea gravel we have used in our back patio area. With 2 large dogs, we needed something to keep it off the flagstone pavers. We bought a yard spray bottle for application. This product works great for the most part and in a basic way. It will not adhere all of the rocks together, it will adhere the ones directly hit by the stream of glue. If those are on top of other rocks and get moved, then that clump moves as a whole which can make the situation worse almost. It clogged the sprayer numerous times. We had to use 2 5-gallon buckets for our little backyard and need more still. It is permeable which is nice for water & does a great job at keeping the rocks in tact between the pavers. It does a great basic job, but for the price and the amount needed to complete the project, along with needing reapplication, I’m unsure that it is worth it. For small spaces, it would be great for a quick fix. However, if your gravel is 2” deep, that is 2” deep of gravel that needs coated in order to fully do as advertised which is near impossible.

Use the lock mulch where areas of the mulch was being washed away. It worked out very well and the mulch hardened within 15 to 20 minutes in the direct sun.

I'm glad I waited to make my review because a couple weeks showed me that this is horribly miss leading. My project is small rocks surrounding my lawn to keep sprinklers away from the fence and the rocks eliminate mud areas. You can see in the video that the rocks have been rinsed and packed prior to applying the "glue". There was more to the video showing the reappearing of white color wheb water is applied to fully cured glue but amazon wouldn't allow the extra minute of video length. I did application as directed on product with dry material that had zero water for more than 2 day prior and after application. Since I'm in northern CA we were 95° and above when I did the applications. My issues with this product are that it's WATER SOLABLE which means water not only breaks it down but the glue re-absorbs the water (after fully curing) and returns to mush after water sits for a while. Yes it takes a couple weeks of sprinklers 5 days a week to have the effect of no application but come rain season (in a few weeks) all of my areas will be as if I never spent countless hours packing and glueing. This product is so water solable I'm not sure they added any nitrogen to the formula because how do you market an outdoor glue that can not hold up a week or two into winter? $460.00 down the drain. Now I'm having to spend another ~$500.00 on an epoxy paint to solidify the rocks in place and it's a race against mother nature because of the wasted time applying fraudulently marketed outdoor glue. I do NOT recommend this product for anyone that actually wants their landscape material to stay put after water exposure. You could save money and just apply Elmer's clear glue which would last longer and not turn white everytime it gets wet. I'm on a very limited budget, and saved for 3 years to get my sprinklers and rock project funding (did all work myself) so to now be over budget by more than $500 is heart breaking and stressful. It will take me a year or more to pay off the credit card from this grossly misleading product.

The product didn’t work very well for me after I tapped the gravel tightly. The manufacturer gladly took it back, even though the bucket was empty. I will admit it rained a little bit before the product completely dried so make sure there’s no rain in the forecast for 48 hours. It can be a very long drying period depend depending how heavy you apply it. The product is a little overpriced in my opinion so I was not willing to try it again.

This stuff is straight-up magic in a bottle. Spray it on, watch it soak in, and boom — your rocks, pebbles, mulch, or whatever loose landscaping bits you’ve got are now glued tighter than my commitment to bad puns. No more rocks in the driveway, no more mulch migrating to the neighbor’s yard, and definitely no more me out there at 7 AM playing 3D Tetris with wet stones after a rainstorm. It dries clear (I did a terrible job spraying it! 😂), holds through wind/rain/dog zoomies, and still lets water through so your plants don’t throw a fit. Plus overspray is water soluable! I even hit it with a pressure washer 24 HOURS after putting it in and the sand between the pavers didn't move! A week later? Hurricane-level winds tried their best. The rocks? Didn’t budge. It’s like giving your landscaping a bouncer who actually shows up sober. Rock Loc team — if you’re reading this (and I hope you are, because product searches are a thing), hit me up! I have a HUGE yard and you have glue!

I had to lock down a large area of gravel (several hundred square feet) placed between paver stones, and found that this compound did the trick at much less cost than the British stuff sold in 5-liter bottles. It looks and appears to work the same, and is thin enough to use with a sprayer which is the best way to apply it other than mixing it with the gravel before it's laid down. I do recommend a good powered sprayer if you're going to do more than a small area at a time (unless you have arms like Popeye). Because I was applying it to existing gravel I opted to spray in place with a heavy saturating coat, and when dry the gravel was slightly darker but looked good and it was firmly locked in place and walkable. I added additional gravel to fill gaps and low spots, smoothed it out and sprayed again and the final result looks and feels like it will last a long time. It goes on quickly enough that an annual refresher shouldn't be a problem, if needed. I wouldn't use this (or the other product) for a driveway but for my application it did the trick!

great product

Worx like a charm

Using it on the rocks between my patio stones. One coat so far and it held up during two good rains and several hot days. The instructions are inconsistent.... for the big bucket online it says it's ready to apply. But on the bucket it says to mix with water. We did it without adding water and it worked fine. Going to put a second coat on. The true test will be when our dogs are outside playing... will it hold up to nails.

I applied two applications of this after carefully following the instructions (hot weather, didn’t rain or walk on area) but it just doesn’t bond together. I have large bark chips mulch and they don’t bond together. It is pretty disappointing. I’m going to just roll out black bird netting before the fall so I can use the leaf blower to quickly remove the leaves. Don’t waste all your time using this product. (I specifically bought because it is supposed to work for large chips, it doesn’t)

Used to secure around fire pit!
