How to Make a Hollow Faux Rock Cover

Objects such as well heads can be unsightly and pose a tripping hazard. This is my solution to this problem. Here, I create a hollow faux rock to cover the drain valve from my newly constructed lily pool.

    How much does it weigh? I? wanted to make a few larger ones that would be portable

  • dperry428:

    It weighs about 10? to 12 pounds

  • mrmakatini:

    Have you made any videos? on making the actual pond liner. Your rock making video was excellent!

  • apauln:

    why? did you have to do another layer after the first casting? why does it have to be sealed? where do you get syrofoam beads? am i asking to many questions?lol

  • dperry428:

    The first layer contains styrofoam beads as the aggregate — not a suitable surface for finishing. The second layer is a sand/cement layer — finishes well to simulate? rock. The styrofoam beads are insulation for cement block; mine came from Menard’s. No, you’re not asking too many questions; glad to help. You might like to watch the series on my channel entitled, “Making Faux Rock for Your Pond”. The first part discusses where to get materials.

  • dperry428:

    The pond liner is made the same? way as the rocks — out of concrete.

    Don is so great. He has inspired me to do a bird bath / fountain / pondless waterfall . Don is a very kind and patient? teacher. I had lots of questions too and he made me feel like he was happy to answer them and help me along.

    @shawniern First layer: 3 parts stryofoam beads, 1 part mortar cement, handful of fiber. Liquid is 3 parts water to 1 part acrylic admix. Second layer: 3 parts sand, 1 part mortar cement, handful of fiber. Liquid? is 3 parts water to 1 part acrylic admix. Acrylic admix is also called fortifier, polymer, or latex.

  • MrDarby76:

    Does anybody know where you can get this polypropylene fiber? I have searched around the web and anybody who? sells it only sells it by the ton!

  • dperry428:

    @MrDarby76 Send me a PM with your email address and I’ll send you a list of sources.? Fiber does not have to be polypropylene. It can be alkaline-resistant glass fiber. Check concrete suppliers and countertop manufacturers as well.

  • 507jbird:

    Don,What is the color and name brand of the acid stain? you used on the wall with the valve on it

  • dperry428:

    I use Butterfield brand acid stain because it is available locally. The three colors that I use? are Taupe, Tannin and Cordovan Leather. Taupe gives shades of brown from light tan to dark, almost black, depending on the amount applied. Tannin has a yellow to orange caste. Cordovan leather gives shades of reddish-brown.

    Great? job master!

  • 824twyles:

    Where do you get? your supplies? Would it be possible to make a waterfall on the edge of a pool?

  • dperry428:

    @824twyles I get most of my? supplies from local home improvement stores. Acrylic comes from concrete supplier. Fiber is ordered online. Send me a PM with an email address and I’ll send lists of possible suppliers.

  • dperry428:

    @824twyles Putting waterfalls at the edge of swimming pools is done all? the time. Google “swimming pool waterfalls”.

  • vdeish1:

    What is the cost to? make the rock shown in the video?

  • dperry428:

    @vdeish1 That is very difficult to determine off the top of my head. My guess is a couple dollars. ? Since I’m not in the business of making them for other people, I’ve never had to cost it out.
