Frequently Asked Questions |

HOW MANY POURS CAN I GET
OUT OF ONE MOLD?
Your mold should
last 10-20 pours and maybe more if properly cared for. Please
read MOLD
CARE in the Basic
Instructions section.
CAN I USE VEGETABLE OIL SPRAY
AS A MOLD RELEASE?
We do not recommend spray
vegetable oil, which may not provide an even, thick coating.
Please use vegetable oils such as canola or safflower,
applied with an inexpensive paintbrush.
HOW MUCH CONCRETE SHOULD I USE
FOR ONE MOLD?
The quantities below ae
the approximate amounts of dry concrete you will need for
each type of mold:
• Round stepping
stone molds: 6 quarts dry concrete
• Square stepping
stone molds: 7 1/2 quarts dry concrete
• Edging Stone molds:
3 quarts dry concrete
• Totem Stakes:
1 1/2 quarts dry concrete
• Planter Feet molds:
1-2 cups dry concrete
Note: due to
the small size and detail of the planter feet molds,
it's best to use concrete mixes free of rock and gravel.
Use mortar mix or make your own concrete with sand and
cement. Or buy a small box of concrete patch, found in
any hardware store.
WHEN USING IRON OXIDE PIGMENTS,
HOW MUCH IS NECESSARY FOR A STONE?
This depends upon how intense
you want the colors, but generally, 3-4 tablespoons pigment
per stepping stone and 1 1/2 tablespoons per edging stone
will produce a pleasing saturation. The colors will appear
muted while the concrete is still wet, so resist adding
extra pigment.
SHOULD I
USE A CONCRETE SEALANT?
Yes, especially if you live in a cold climate where
freezing and cracking of stones are an issue. Sealants
come in both glossy and matte finishes and can be found
in any home improvement center. For more ideas on fortifying
stones, see Concrete in Cold Climates in our Basic Instructions
section.
I HAVE USED
AN ACRYLIC PAINT TO DECORATE SOME OF MY GARDEN STONES.
IS THERE A PRODUCT THAT WILL HELP THE ACRYLIC LAST LONGER,
OR IS THE ACRYLIC PAINT A SEALER ITSELF?
You do not need to seal the stones if they've been
painted with acrylics. After a year or so of exposure to
the elements, the paint will probably start flaking. Simply
remove the flakes with a wire brush then re-paint the stone.
I AM CURIOUS
ABOUT YOUR COLOR WASH USING A SLURRY OF IRON OXIDE, PORTLAND
CEMENT AND WATER. EXACTLY WHAT ARE THE MIX RATIOS?
This is a matter of a little experimenting plus
personal preference. Start with a cup of Portland cement,
a tablespoon or two of oxide and enough water to create
a thin pancake batter consistency. Apply it to your stone
and see if you like the effect. If not, rinse off and thicken/thin
the slurry or make another slurry using more or less color.
After the slurry has dried and cured for a week or so,
apply a concrete sealant. This will increase the durability
of the slurry.
IN YOUR INSTRUCTIONS,
IT SAYS TO LET THE STONE CURE FOR 2 DAYS. DOES THAT MEAN
TO LEAVE IT IN THE MOLD FOR 2 DAYS OR LET IT SET UP FOR
A FEW HOURS, THEN REMOVE FROM THE MOLD AND SET ASIDE
FOR TWO DAYS?
The stone needs to cure 2 days before demolding,
then allowed to cure an additional week before placing
in the ground. If demolded after just a few hours, it will
simply fall apart.
WHAT ARE EDGING
STONE MOLDS AND WHAT DO YOU USE THEM FOR?
Edging stone molds are used to create decorative borders
around flower & vegetable beds, lawns and trees. Using
a small hoe or trowel, dig a channel approximately 2-3
inches wide and 4 inches deep, then set the edging stones
vertically into the ground (plain half in the ground, decorative
half above ground). Tamp soil firmly around the stone.
IF YOU ARE
MAKING MULTIPLE STONES, HOW DO YOU PRESERVE CONCRETE
WHILE THE STONE IS SETTING UP?
You don't. Once you have added water to the concrete,
you need to pour all that has been mixed. Mix up only enough
for the items you are pouring. If any concrete is remaining
in the bag, close the bag tightly. Dry concrete actually draws
moisture from the air. Your mix can therefore become a bit
lumpy over time. |
