Intro: Duplicate and Create a Concrete Poodle Using ComposiMold!

This Instructable will teach you how to make and duplicate a large concrete Poodle, German Shepher, French Bulldog and other types of garden statues.

STEP 1: Create Your Mold Box.

  1. You can use wood or plastic to make your mold box just make sure to seal the wood.
  2. Spray with a heavy coat of mold release.
    1. The pieces that I used were not sealed which made it challenging to remove the pieces from the mold.
  3. The mold box is 12”X18”X29” We made sure the mold was at least 1 inch thick around the entire statue.
  4. Fill in all the cracks where your liquid mold making material ComposiMold could escape.
    1. I used silicone caulking to too fill in the gaps and cracks. If you want to guarantee the ComposiMold wont escape, fill the mold box with water and see if it can hold without any problems.

STEP 2: Prepare Your Master Statue

  1. Make sure your master is sealed.
  2. Coat it with mold release.
  3. Place it in the mold box and spray it with a heavy coat of bubble buster.
    1. Bubble Buster is a great way to prevent bubbles
      from sticking to your part by breaking surface tension and allowing the bubbles
      to rise to the surface.

STEP 3: Create Your Mold

  1. Melt the ComposiMold in a 55 gallon drum or a double boiler
  2. Use heat belts that have a maximum temperature of 160 degrees Fahrenheit.
  3. We used about 250Lbs of ComposiMold for this project.

STEP 4: Demold

  1. For large projects like this wait 24 hours before removing the mold box. If it still feels soft it has not finished cooling.
  2. We chose to pour the mold in one part which means that we had to cut the mold in order to get the original statue out.
    1. This process does work, however I would highly recommend creating a parting line ahead of time by inserting a plastic sheet where you want the mold to come apart before pouring the ComposiMold. This will make demolding a lot easier and a nicer looking mold.
  3. Once you do get the original out of the mold coat it with mold release
  4. Put the two halves back together in the mold box and prepare it for the cement.

STEP 5: Create Your Duplicate

  1. Use Pro Finnish 5000 concrete mix made by Quickcrete (or similar) which can be found at most hardware store.
  2. Pro Finnish 5000 works great with ComposiMold because it only takes 14 hours to cure.
  3. Mix 80 pounds of cement with 1 gallon of water.
  4. Pour the concrete into the mold one section at a time making sure all the areas of the dog filled especially its nose.
  5. A hammer drill works great for vibrating the mold allowing the cement to flow throughout the mold.
  6. The cement should be removed from the mold after 14 hours to allow it to finish curing.

STEP 6: Demold the Duplicated Statue

  1. Gently remove the duplicate from the mold to prevent cracking and damage.
  2. Admire your creation then create more or re-melt the mold and make a new mold.

Yes, but how much Composimold did you use for this, and how much did it cost?

I think that I have seen about a quart of it for $30.

Thank you for the comment! We used about 250lbs of ComposiMold for this project. When you buy ComposiMold in bulk it will cost $10/lb or you can get used ComposiMold for $6.8/lb wile supplies last. Do you have a mold making project you are working on?

Hello do you have a UK supplier that sells at a similar bulk price ? thanks

Thank you for the question! We have UK suppliers but none that sell ComposiMold in bulk. However, we do ship directly. How much ComposiMold are you looking to get?

Would it be safe to use on a living being, such as a human foot? Not worrying about the need to set for how ever many hours. Just is it physically safe for that sort of thing?

Great question! We do not recommend using it on the skin because of the possibility of burns. However if you are extremely careful and have a good and accurate method for measure the temperature of the ComposiMold you can apply it to the skin once it has fully cool below 115°F. Once it is below 115°F it will be thick.

Holy EXPENSIVE just to make a mold! I couldn't imagine for the life of me why someone would have used such expensive mold material for this project (which seemed like a really cool project)... but then I realized... THIS IS AN AD! Project posted by manufacturer of mold material...

Thank you for the comment, and compliment! Out of curiosity, do you have a concrete or mold making project you are working on?

Nice Instructable!

Question, did you use 250 or 25 pounds? 250 pounds is @ $2500.00 for mold material, not very cost effective, I am very intrigued by the fact this material is reusable, that is a huge plus. Any idea on how many times it can be reused?

I have also made 2 part molds by laying object on side, pouring half, curing, then spraying mold release and pouring second half, no separator needed

Thank you so much for the comment and compliment!

This project used 250lbs of ComposiMold. ComposiMold can be re melted over 35 times for 35 or more unique projects!

Creating a two part mold using the method you have suggested with ComposiMold is possible; However you have to worry about the heat from pouring the second half. If you do not chill the first half the two halves will fuse/melt together. With this project It is possible if you have a big enough fridge/freezer or do it during the cold winter.

Here is an example of a smaller dog statue that we molded using 40lbs of ComposiMold https://www.youtube.com/watch?v=OkR9t7Os6l8 You can also do a brush on mold which would drastically reduce the amount of material needed; as shown in this video https://www.youtube.com/watch?v=aFR2eJymfDQ

Out of curiosity, what type of molds have you created? What type of mold making material did you use?
