PROJECT TIPS
Form Construction:
• Use melamine coated particle board, not
white painted particle board. Melamine is
a particle board that has been treated with
a plastic coating on both sides. Make
sure the melamine surface is free from
any scratches, smears or cracking.
Remove any stickers from the melamine
form and make sure all adhesive residue
is removed.
• When forming the mold ensure screws
don’t protrude from the surface of the
melamine mold. Hint
: Put clear packing
tape over all of the screw heads to avoid
concrete spillage in the screw heads
which will make mold removal very
difficult.
• It is best to vacuum and wipe down the
inside of the form with a clean rag and
warm water or acetone. Use of other
cleaning products can leave streaks and
residue on the form that you may not be
able to see until the top is removed from
the mold. Thoroughly dry the inside of the
form prior to pouring the mix.
• Do not apply a form release agent to the
melamine
Caulking of Forms:
• Use 100% silicone black caulk. All forms
must be caulked in the corners to avoid
having razor sharp edges.
Make sure that
th e c a u lk is s m o ot h as a ny
imperfections in the caulk surface will
be reflected in the edge of the concrete
countertop
. Be careful that sawdust
residue does not get into the caulk or it
will show up on the countertop. Any
sawdust residue that gets on the
melamine mold can be simply vacuumed
up with a shop vacuum.
•
Use painters tape to protect the
caulking area. Remove the tape once
the caulk is in place.
Use a razor blade
to remove excess silicone caulk. Excess
caulk that is not cleaned up prior to
pouring the mix will leave a mark in the
concrete.
Mixing:
• Plan out your mixing procedure. A 50#
bag of Concrete Countertop Mix with
proper water addition can fit and be mixed
in a five gallon bucket. It may be
advisable, depending on the size of your
pour, to have multiple five gallon buckets.
• Pre-measure all water to be used. Do
not over water. Mix 5.5 pints of clean,
the sides of the form. Put down some
small pieces of foam next to the base of
the form. Then hold the base of the form
and the countertop, lift the countertop
onto the foam in a vertical position. Gently
remove the bottom of the base and gently
remove any cut outs. Using caution lay
the top down on foam scraps with the
surface of the countertop up. Using a
sanding block smooth all the edges and
remove any imperfections/defects.
Finishing
The surface of the countertop can be wet
polished or cleaned and sealed, as is,
depending on the desired appearance.
Follow all instructions for the sealing
products used. If pinholes are present use
a non sanded patch to fill any pinholes or
to touch up any imperfections or defects
along the edges prior to finishing.
Clean Up
Typically water will satisfactorily clean
tools after using Premium
Concrete
Countertop Mix
™
. If the material has
begun to harden, warm soapy water may
be helpful for cleaning hands and tools.

WARNING: INJURIOUS TO EYES!
potable water per 50# bag of Concrete
Countertop Mix for 3 minutes. Allow the
product to sit/slake for 3 minutes and then
remix for 2 minutes. Additional water is
not required and may negatively affect
the finished product.
• Add water to the empty bucket first, then
add Concrete Countertop Mix. Water and
mix should be at room temperature
(65°-75°F).
• Best results are obtained when a five
gallon pail and a mechanical mixer are
used to mix the product. Be sure to use a
mechanical paddle mixer – no shovels,
hoes, wheelbarrows or barrel mixers.
Pouring into Forms:
• For longer sections and large
countertops, don’t mix material that you
will not be able to lay in 20 minutes.
Always try to have sufficient material to fill
the bottom surface of the mold in one pour
to minimize pour lines from showing on
the surface.
• Make sure forms are tapped with a
rubber mallet or lightly vibrated with a
palm sander (without pad). This helps to
consolidate the mixture.
Removal of Forms:
• Be sure to wait at least 18 hours before
de-molding.
• After de-molding, it is desirable to allow
the countertop a few hours of drying time
before applying sealers. It is important to
follow the sealer manufacturer’s
instructions as to timing of sealing and
temperature considerations.
• Be sure to lightly sand and smooth the
bottom edges of the countertop to
eliminate sharp edges. Be careful sanding
corners, always sand lightly towards the
top/piece to avoid chipping the edges.
