How To Make Molds For Concrete Statues
Making latex molds for concrete is relatively easy, and cheaper than buying concrete molds, the most important part is your first 2 coats of latex rubber. Put it on thin so it catches all the detail of the piece you’re making a mold of. After that, you can brush it on normally like you would if you were painting a wall. I personally use 30 coats of latex per piece. I don’t use a thickener. For bigger pieces, you can apply more for added strength. I use Holden’s Latex rubber because of its durability. I buy by the gallon. You can get it on Amazon here, Holden’s Latex rubber
After your latex rubber cures, you will need to make a mother mold for it, so it holds its shape when you pour cement in it. For that, you’re going to need isophthalic resin (Amazon Link). This stuff has a very powerful odor. Be sure to be outside or in a ventilated area when using that stuff! The isophthalic resin should come with a hardener that you mix with the resin before use. You’ll also need fiberglass mat (Amazon Link).
What I do is tear the Fiberglass mat up into small squares (depending on size latex rubber model) before I start fiberglassing. Once the resin is mixed with the hardener, you only have so much working time till it sets up.
The best way to show you how to do this is by watching a video on youtube. The guy on the video isn’t me but, He shows you spot on, on how to make a fiberglass mother mold. It’s a lot easier to see it done than to read about it. It’s kind of hard to get the hang of it but once you do, it won’t take you long to finish a piece. Here is the video.
If you get good at making these type molds. You can make good money selling them on eBay. The more detail the mold has the higher price you will get for them. Also the bigger the mold the higher the price.
The best part of the whole process is, after your done making the mold, is pouring the mold with concrete and demolding it the next day to see how it turned out.
Making concrete statue molds and selling them can be a very rewarding hobby. Also making concrete statue molds can be very profitable. The profit margin is high and people love them, especially bird baths.
