Miracle Mud Black Cement

Directions for use.
It is strongly recommended that you perform a simple test prior to applying
the Miracle Mudd to your finished work. This test is to verify the setting
properties of the product. Check the color of the liquid: it should be medium
to dark amber in color.
In a disposable dish mix a small amount of the liquid and dry together to the desired
consistency. Allow this test batch to sit, undisturbed, for 24 to 48 hours. After the waiting
period check the hardness by gently poking it with a pointed stick of some kind - It may
not be completely solid at this point but it should not crumble.
If it shows any crumbling, or does not seem to be set as it should, mix another test
batch, adding a small amount (approximately 25% of the volume) of Boiled Linseed Oil*
to the liquid first. This may slow the drying time so give it at least 48 hours. If you still
find crumbling in the test batch, return the liquid for a replacement bottle.
• Mixing Miracle Mudd®: Place a quantity of the liquid in a container (old coffee cans or
something else disposable) and add the powder a little at a time. Mix thoroughly, adding
more liquid or powder as needed. Once it appears to be the preferred consistency (this
will vary according to individual preference) allow it to set for a couple of minutes and
mix again.
• It is wise to apply Miracle Mudd® with an applicator of some kind, rather than your
hands. A large "stenciling" brush with the bristles cropped short works well. Apply in a
circular motion to push the mixture under the leaves of the came.
• Once all of the lead has been sealed (when cementing a large panel work in sections)
sprinkle the whole panel liberally with Whiting or Sawdust. Lightly brush it over the
surface, and allow it to set for a minimum of fifteen minutes. Depending on the weather
conditions, cleanup can begin immediately, but if the weather is cool or damp, wait the
minimum time. If it is warm and dry, begin cleaning immediately.
• It is important that Miracle Mudd® be cleaned from the lead came surface and any
textured glass promptly, or it will be difficult to impossible to remove once it has had
time to set up.
• Using whatever stick or tool is your preference, trim the excess cement from the edges
of the came — vacuum or brush off — then using a soft bristled brush (a "bench" brush
with shortened bristles works well for this) brush in a circular motion to loosen the
cement from the surface of the glass and came. Vacuum or brush off again. Polish the
surface of the lead with terry cloth, or a polishing brush designed for this purpose, to
shine and darken the lead. Then finish any trimming and clean up any "blurring" from
the glass with a soft cloth.
• In most cases, the panel can be turned and the other side done right away. If it is a
large panel, allowing it to set for a day or two and then doing the other side, will make
handling much easier.
Helpful Hints:
• If you are using Miracle Mudd® in the large "studio" size, store your liquid in an old
vinegar bottle or similar glass container. Over a period of time any oxygen in the plastic
bottle will begin "soaking" through the soft plastic causing it to “suck up.”
• Terry cloth is very good for getting the cement out of glue chip and similar textures, as
long as it is done promptly. It requires some elbow grease. Don't wait!
• If you have a "loose" panel to cement, mix the Miracle Mudd® fairly thick to avoid
having it run through to the other side.
• On large panels, solder, cement and clean one side, wait two days and turn it and
solder and cement the other side. Mix it thick for the first side so it won't interfere with
the soldering on the other side.
• If you do get some oozing through that makes the joints difficult to solder, don't use a
wire brush to clean the lead. Using a wire brush works the oil into the lead, instead of
cleaning it off. Rather, slice off the affected area with a sharp craft knife and then
• Miracle Mudd® is much easier to mix if you add the dry to the liquid, rather than
adding the liquid to the dry.
*Boiled Linseed Oil is available in artist supply and hardware stores.

  • Product Description

    When you scrub cement under the lead, zinc or brass came in your panels, you add strength, weatherproofing, and an instant patina to your project. Don't skip this essential step - Miracle Mudd makes it easy!

    This unique 2-part black cement system takes the place of traditional pre-mixed putties, so you can mix as little or as much as you need for each project. Because it comes as 2 parts, there's no settling or struggle to re-mix your cement - and there's no limit to the shelf life.
    Contains approximately 10.5 oz. of Miracle Mudd dry mix and large Miracle Mudd liquid solution included. Makes approximately 1 lb of cement mixed.

    To use:
    1.  Pour the liquid into a mixing container. Stir in a bit of powder at a time until you've reached your preferred consistency. You can choose how thick or thin you prefer - most artists report that they prefer to use something in a range between brownie batter and bread dough. Allow to set for 10 - 20 minutes, then stir again before use.
    2.  Apply to your project with a brush, pushing the Miracle Mudd under the came.
    3.  Apply whiting powder and clean your project promptly to remove excess Miracle Mudd. Note: Once Miracle Mudd has dried completely it will be difficult to remove, especially from textured glass.
    4.  Allow project to dry flat 24 - 48 hours.
