How to cover my foundation

You could try making or buying a stamped concrete stencil and using it to paint the block to give it a stone look.

Use outdoor acrylic paint that you can purchase at any craft store. Use a stencil that looks like a natural stone or be creative and paint the stone look on yourself.

You can use a path maker. They use them for sidewalks and patios and they come in different shapes and sizes so you can custom them to your project. This is a fairly cheap way to get the look without investing a lot of money because they are made out of cement/concrete. Make sure the place where you make them is flat and level maybe a driveway or garage. Lay down a plastic lining like a tarp on the ground and coat with oil (so they release easily). Make all the pavers on this surface. You can make full pavers or before they are completely dry but set you can remove the mold and gently break apart the “rocks“ with a mallet and chisel. The amount of time you need to wait would be dependent of your weather and climate. So you will need to run a test to find the perfect timing. Once you get them made you can either stain them or leave them natural. But if you decide to alter the color do it before you adhere them the the house. Once that is complete you can adhere them to the house with mortar, kind of like laying tile. Once your mortar has cured you can pipe in the “grout“ into the seams (they make special bags for this available at big box stores like Lowe’s and Home Depot) if you want it to be a contrasting color. Once everything is complete you can sit back and admire it. I have done this myself on my last home and it turned out beautiful. As of last year it was still holding strong and I did this approximately 4+ years ago. As an added note if you decide to separate the rocks you may want or need to sand off and jagged pieces once they have cured. You can accomplish this with the wet sanding method or I just used a spare brick I had to make them uniform. It is a lot of work but worth it😁
