Mulch Glue on Pea Gravel – 1 Year Review (S5E5)

Mulch Glue by PetraTools is an easy to apply glue that I applied approximately 1 year ago. In this brief video I cover several questions that were generated in the comments from my original video.

Prevent Weeds?

Does the mulch glue prevent weeds? Well, it short, no. This is a bonding product that bonds the mulch, or pea gravel in my case, to each other. It does not create an impermeable barrier from weeds.

Water Flow Restricted?

How does it handle rain? Rain flows straight through the product. As mentioned above, the glue bonds the substrate to each other and allow water to completely pass through. Yes, it is permeable.

Work on Slopes?

Yes, my entire bed has a slight slope and the area around my heat pumps have a 35-45 degree slope. Held like a champ.

Check out the video below for more information and to see how it held up.

Easy to Apply

It was very easy to apply. Simply mix it 1 part product with 2 parts water. In this video I used 32 oz. of product; so I used 64 oz. of water (1/2 gallon). Shake it up and start spraying. Yes, it really was that easy.
