Even though I have concrete garden art to share I thought I'd start by sharing a few pieces I made using pebbles. We used to go to Michigan every summer and bring back some of the most unique pebbles we collected and last year I finally found a project to use some of them! Since our mailbox is located just down the road at the nursery we've never had an address marker so I came up with a design and made one. Most of the pebbles used were from our collection but I did buy a few of the bags of "River Rocks" from Michael's for some of the details. Unfortunately I don't have photos of the whole process but I started with a leftover piece of cement board from the tile floor we had installed the previous year. Having no experience with a project like this I had the whole design laid out before I realized I had no idea what I was going to use to glue the pebbles.
I mistakenly thought I'd be able to find something like an self-leveling epoxy that I could just pour over the whole thing but then couldn't find a product that was waterproof or water resistant.
I decided to use a waterproof construction adhesive and had to remove all the pebbles and re-create the design a second time.
Spread small sections with the adhesive, quickly arranged the pebbles to re-create the design and continued to spread more sections of the adhesive until the entire board was covered.
I made sure that every little space was covered with pebbles but now that I've started working with mosaics I realize I could have just grouted the whole thing. Lesson learned, next time I'll know better!
