DIY Affordable Boulder Address Plaque for Outside

3 Materials
1 Hour

We received a free real boulder and we decided to do something with it to enhance our home's front. Follow along and see how I made our DIY rock address plaque after giving us one of the unique boulders on his property.
BEFORE IMAGE: We found a place to put it. Position the boulder the flat surface is facing forward so people can see it from the street. Since it was near a lamppost, I did not need to have a light shine on it. But, if you want it, you can add a spotlight solar-powered light in front of it. 
The screws and anchors came with these numbers but it was needed.
We used SteelStik Steel Reinforced Epoxy Putty Stick to help adhere the numbers to the boulder.
Center the middle number, so you have room on either side for the rest of the numbers. The adhesive is a putty consistency, so you will need to roll it around to adhere to the metal number. Try not to add too much, or it will be noticeable on either side of the metal number. Follow the instructions on the container. Hold it in place for a few minutes. We did not need to tape it in place. It adhered fairly quickly.
Here's the finished boulder address plaque. We continued adding the numbers with the adhesive. Be sure to line up the top and bottom of the numbers to make sure from a distance; it looks straight. If your stone is taller, you can angle the numbers or place them vertically.

    The grout along the bottom of the Back Splash that comes down on the Counter is coming off. What do I use to fix it? The countertop is Granite

      You will get more answers if you post this as your own question, not on someone else's project. Meanwhile, scrape out all loose grout. ALL loose grout! Clean all the dust and bits up. If you wash, make sure to allow everything to thoroughly dry or you will set yourself up for mold.

      Use some latex caulk made for bathrooms and kitchens that matches the grout or blends well with the countertop. Cut an angled opening at the top of the applicator tube - make it about 1/8" - 1/4" hole. If you don't know how to caulk, practice squeezing the trigger while simultaneously moving along to apply on something else. You want to fill the opening but not get it everywhere. Try to move as smoothly as possible and you can then follow that up by wiping away the excess while still wet. If you haven't done this at all, they do sell various cheap little tools to help properly wipe/shape the caulk.
