TROUBLESHOOTING THE STONE VENEER MAKING PROCESS

As long as you keep your molds out of direct sunlight, and you only use concrete and plaster mixes , the molds will last for years of daily use.  After 10+ years the main questions are below.  Make sure to follow our how to videos to save yourself from having to learn the hard way.

There is la lot of left over pigment and concrete in my molds after I use them. Pulling your stones out too soon will cause this problem.  You need to wait a little longer for your stones to set properly in the molds. 

I have a lot of airbubbles in my stones.  Vibrate or shake the molds a little longer.  The thicker your concrete mix, the longer you will need to vibrate/shake.​  You can also be over vibrating/shaking the molds which can introduce air into the concrete mix. 

The stones have a lot of pigment that rubs off.  Make sure to flip the molds over to dump out excess pigment before pouring in concrete.  You will not need to cake the pigment on the molds for them to work.   ​

We will post more FAQ's as they arise, but we doubt there will be too many more.  Just follow the How To Videos.
Please take note that the how to make stone veneer instructions below are specifically created for latex rubber stone veneer molds.  If you are using plastic or polyurethane rubber molds you will not get the same quality results.

You do not need a release agent with our molds

Take the molds out of the box and lay them on a flat work-surface.  If the molds came out the box a little warped looking, from shifting around during shipping, just lay them flat for a few hours and they will be 100% back to normal.

Once the molds are in place on the workstation, you are now ready to add accent colors to the stone veneer molds. Apply the accent colors the same way they are being applied in the video above.  

After your molds are nice and colored up, you are now ready to create your concrete mix. Most people will use a premix like Quikrete, until you are ready to manufacture stone veneer at a higher volume.  Just follow the instructions on the bag and pour the concrete mix into the molds if you are using a premix.  

Once you have mixed your concrete you are now ready to fill the molds. We suggest pouring 1 gallon bucket full of concrete for each mold.  Just wipe away the excess concrete and apply it to the next mold.  

After the molds are full of concrete they are ready to be leveled out by vibrating/shaking them for 30 seconds, or so. Once vibrated you can rake the back of the stone veneer to create a surface that will grab onto the wall during the stone veneer installation process.  

Make sure to let the stones sit for at least 7 days before you apply them to a wall.  Do not store the curing concrete stone veneer in direct sunlight for the first 7 days, at least.  The best way to store the stones is by covering them in plastic at temperatures above 70 degrees F.  We have successfully cured concrete stone veneer at 120 degrees, while covered in plastic.

HOW TO CREATE CUSTOM COLORS FOR STONE VENEER

Directly below we will cover an advanced coloring technique that can be utilized by the Do It Yourself community, mainly.  Step 1 starts where our basic "How To Make Stone Veneer" above leaves off.

Items needed
  • Stone Veneer Molds
  • A Concrete Mix
  • Rags
  • Color Matched Paint

Step 1 Custom Color Matching:
Take your color samples to the paint department at your local paint supplier, that has a computerized color matching system. Ask for your custom paint to be created using the highest quality masonry paint available.

Step 2 Blending the Paint:
Simply mix the paint at a ratio of 1 part paint to 1 part water.

Step 3 Preparing the stone veneer to be painted:
The only prep needed for the stones is saturating them in water. The water will carry the paint deeper into the stones. There are various ways you can go about saturating the stones in water. Some people use a concrete mixing tub to soak the stones prior to coloring, and some people use a water hose. If you are using a concrete mixing tub filled with water to soak the stones, change the water if you can't see through to the bottom of the tub.

Step 3 Apply the Paint to the stone veneer:
Using a lint-free cloth dipped in paint, apply the paint to the wet stone veneer. Using a water soaked cloth, wipe or dab the excess paint from the surface of the stone veneer. The harder you wipe or dab the stones the lighter the color will be. Just like painting a piece of paper, the stones can be painting with as many different colors as you can fit on the stones. Most stone veneer has 3 different colors.

Step 4 Ready for installation:
Once the paint drys the stones can be installed on the wall. Paint drying and paint curing are not the same thing. Keep in mind that the paint can be easily scratched during the curing process. Paint is dry to the touch in a few minutes at proper temperatures, but will take up to 30 days to cure, depending on the type of paint type. For best results it is best to wait for the paint to cure before installation, but if you're careful you can install the stones sooner when they are dry. And you're done.
