Installation Guide

• Prepare the molds using a lubricant or a mold release. This will help
in removing the casting from the mold later and may extend the
life of the mold itself. We recommend the use of any concrete
release agent or cooking vegetable oil spray (use sparingly or you
will see more surface bubbles).
• Mix the concrete according to the instructions from the concrete
manufacturer, mixing a small amount of water at a time until you
achieve a consistency that is well mixed, and is thick, not runny;
similar to the consistency of crunchy peanut butter.
Items Needed:
*History Stones cobblestones molds)
*80 lb bag concrete mix (will create apx.
two cobblestones)
*mixing tub or wheelbarrow
*mixing tool, i.e. small shovel
or garden hoe
*lubricant ) or a mold release
Filling Molds
General Preparations
Applications & Decorative Tips
Instructions
Cobblestone Molds
1. Begin by pouring only about 1/3 of the concrete mixture into the mold.
2. Gently shake and tap the bottom and sides of the mold to eliminate all air bubbles. Continue by pouring the
mixture in small batches stopping each time to shake and bounce out the air bubbles. When filled, the top of the
concrete should be flat and even.
3. Keep the mold in a dry area to cure for 24 to 48 hours on a level surface in moderate temperature.
Unmold Cobblestones
Gently turn the mold upside down onto a soft surface, like grass or a piece of
carpet for example, and pull sides away very gently from concrete and tap
lightly on the back. If the mold is stiff you can soften the plastic a bit by
setting it in the sunlight to warm it or use a hair blow dryer carefully just to
warm the plastic and make it more flexible.
Do not walk on your stones for several days to make certain the mortar is set
all the way through the stone.
Laying cobblestones - you may lay your
cobblestones the same as you would for any
stone or tile pathway or patio, i.e., mortar in
place, or lay upon a fine gravel or sand base. Be
sure that the ground is smooth and even to
provide a stable base.
Patio - Use four quarter round cobblestones to
create a full circle and surround them with
square cobblestones to enlarge your patio
Pathway -- lay your pathway using the square
cobblestones and use the quarter round
cobblestones to show the corners of the path.
Decorative Tips
*Add concrete colorant to the concrete mix (purchased in home improvement stores
near the concrete/mortar) We used a brick like concrete colorant for the cobblestone
set shown above. This will give solid color through the entire cobblestone
* Apply a concrete stain to the cobblestones once they are set up for an "old world"
or aged look (stains come in a variety of colors, i.e., jade, coffee, mahogany, ebony).
Concrete stains are beautiful, and provide the most natural, interesting finish. You
can find these stains at home improvement/paint stores
Color Design:
* Use two or three colors to add to the design of a pathway or patio
* Border the pathway or patio with an accenting color
* Use an accent color for the cobblestone circles
