Works on slope

[This review was collected as part of a promotion.] We used it on a slope and it held the stones there which I was surprised about. I’ll be using the rest on a flat surface. I’m hoping it doesn’t breakdown from the sun.

So far, so good!

[This review was collected as part of a promotion.] This product seems like the answer to keep your mulch put. Isn't it the worst when you get your garden all set for the season but you always need more mulch or a refresh? I am interested to see how durable it is throughout the season, but so far so good! I would definitely recommend anyone with a house project to check this out.

Great invention!

[This review was collected as part of a promotion.] We struggle to keep our mulch in place over repeated grass cutting and weed eating. This product is simple to mix together and spray on and its supposed to act as a glue type adhesive to keep your product in place. I’m excited to see the longevity of this product because if it lasts as long as it says, it will be a lifesaver! We have only had it on for a week but so far so good!

Game changer for landscaping

[This review was collected as part of a promotion.] What a game changer. Loved the product, the texture but not the smell. No mess or barely any clean up required. My backyard looks amazing and it feels this stuff will last for a while.

Rocks shine a little and stay in place

[This review was collected as part of a promotion.] We started to pour this on the rocks next to our sitting area, then my husband had a different idea. While I was at work he surprised me with this Beautiful Butterfly garden and used this rock glue on it. It turned out beautifully. Yhe rocks have a little shine to them and stay in place. Now our fur babies won't kick rocks every where.

Great

[This review was collected as part of a promotion.] I love this mulch glue. It is perfect for my flower beds in the front yard. It helps keeps from a huge mess each time there is a storm or when we use the leaf blower. It lasts awhile so it’ll make the front look wonderful for awhile. Didn’t take long to dry either.

Multiuse garden glue

[This review was collected as part of a promotion.] The process for using this was pretty easy. Definitely need a sprayer. You mix the glue with water and go. Be sure there is no rain the forecast. Wash up with soap and water. Used to help keep the rock on the edge of the sidewalk in the landscape.

It locks everything in place

[This review was collected as part of a promotion.] Every year I put down mulch only have it blown away when the landscaper does the lawn. So this year I am going to see if the Petramax Lockscaoe Mulch & Rock glue does the trick. It’s been 24 hrs and today is slightly windy and so far so good. I was kind of scared when I applied it because it goes on white but dries clear thankfully. It really locks the mulch in place. I would highly recommend.

A simple, effective solution that keeps mulch and rocks in place, making landscaping look cleaner and last longer with minimal effort.

[This review was collected as part of a promotion.] I have to admit - I have never used a product like this before, as it always seemed like something for professional landscaping. But after receiving LOCKSCAPE Mulch & Rock Glue as a gift, it was pleasantly surprised. It works by binding mulch, rocks and gravel together, helping everything stay in place even with wind or rain. My outdoor space instantly looks cleaner more put-together, and I don’t have to constantly fix or refresh it. Overall, ...

No joke this Lockscape mulch and rock glue works!!

[This review was collected as part of a promotion.] I received this product in exchange for my honest review. The packaging was very well descriptive and easy to understand application requirements. I used my existing sprayer I had at home for this. The product goes on well once you have the nozzle set to wide spray. The product goes on white and dries clear. I have plenty of product to cover my backyard beds. The product held up to its standard of holding the mulch in place. It’s super easy now...

Wonderful at weather proofing and polishing my landscaping.

[This review was collected as part of a promotion.] I honestly didn’t expect to love this product as much as I did, but this had been a game changer for my yard. After putting in the effort to effort to freshen up my landscaping the last thing I wanted was for my mulch to have the possibility to wash away or be a complete mess after a storm. This held everything in place and has made the whole place look so much more polished and put together. The product is nice and light weight and covered so ...

Solid Product!

[This review was collected as part of a promotion.] I use Lockscape Mulch and Rock Glue for my moss art. Overall it does the job well! It has a decent hold and helps to reduce the shedding of the moss over time especially when it is bumped into! Application was easy and it dries in a way that it blends well without leaving a weird residue. It’s not a permanent solution but it works well for what I need it for. I’m interested in using it on my stone outside but the weather conditions haven’t been...

It really works

[This review was collected as part of a promotion.] This stuff works great! I got my husband to mix it for me in a sprayer and these rocks stuck great! I like it comes in a jug and it's concentrated and you just mix 1:1 ratio with water. Then spray it and turn the rocks and spray more. I'm really impressed!

Absolutely love how this looks?

[This review was collected as part of a promotion.] Since putting down the rocks the rocks just haven't stayed in place like we wanted. So doing glue was our next step. The application process and mixing process was very easy!! Love how it turned out! Going to do another round just for some extra strength!!
