Instruction
The mosaic process is very easy,
relaxing, and fun. Mosaics are
the perfect addition to any
studio. After a piece is
finished there is always a sense
of accomplishment and pride.
Please read below for a detailed
photographic description of the
steps in the mosaic process from
start to finish. It is amazing
that something so beautiful can
be so simple. Use your
imagination and create a
masterpiece.

|
|
|
step ONE
The first step in the mosaic
process is to find a rigid
surface to mosaic. We chose
one of our Basic Picture
Frames. We have many
surfaces to choose from.
Tile Mastic, available at
your local hardware store,
works on all of these
surfaces. However,
WeldbondŽ
is more effective on
non-porous surfaces such as
glass. This
product is easier to work
with than epoxy or E6000. |
 |
|
step TWO
After you choose your
surfaces, it is time to
design your piece. Your only
design limitation is your
own imagination. You can
draw it on paper, directly
on your piece, or lay it out
on your surface. We decided
to use Metallic Gems and
Smalti for our piece. We
decided to start with the
edges and work our way in.
Lay down your adhesive in
sections. Avoid using so
much adhesive that it
squishes up between your
pieces. This leaves no where
for the grout to go. |
 |
|
step THREE
This step is optional. If
you want to cut and nip
tesserae for your designs,
it is very simple. You can
use either a Tile Nipper or
Wheeled Glass Nipper as
shown here. You will simply
put your tesserae in the
"mouth" of the tool and
squeeze down. Nipping and
cutting allows you to cut
pieces to specific sizes for
your designs. The Wheeled
Nippers are a favorite! |
 |
|
step FOUR
Now that you have your first
section of adhesive down,
you will now apply your
tesserae (mosaic pieces).
Place each piece on top of
your adhesive as desired.
You need to leave a minimum
of approximately 1/8"
between each tile to leave
room for grout. You can
space your pieces out
further if you like. A good
rule of thumb is a 1/8"
minimum and 1/2" maximum
space between pieces. |
 |
|
step FIVE
Lay down your next section
of adhesive. Work in small
areas at a time. This keeps
your adhesive from drying
out if you are working
slowly. It will also give
you stopping points if you
want to take a break. You
don't have to do a project
in one sitting. |
 |
|
step SIX
Start applying the rest of
your tesserae to your piece.
It can make it easier to
grout if you make the pieces
near the edge of your
surface somewhat flush to
the surface. Work section by
section until you piece is
completely covered as
illustrated in step six
below. |
 |
|
step SEVEN
Here we show the piece
completely covered with
tesserae. You can also
mosaic the sides of your
Frame, Mirror, or Plaque if
you like. You should let
your adhesive set for 24-48
hours before grouting. After
it has cured for this amount
of time you are ready to
grout your piece. It is up
to you as to what color of
grout you use. If the main
them of your piece is darker
tesserae then you might want
to use a lighter grout so
contrast the tesserae and
make it stand out. The
opposite is true if you used
light tesserae. |
 |
|
step EIGHT
On most of our designs we
use a pre-colored sanded
Grout. Our grout comes with
mixing instructions. If you
buy your grout elsewhere,
follow the instructions on
the package. You will want
to put your grout in a
disposible container then
add 1 tablespoon of water at
a time to
your grout until it has a
thick oatmeal like
consistency. |
 |
|
step NINE
Pictured here is the oatmeal
consistency that your grout
should be. If you
accidentally add to much
water simply let it sit for
a few minutes and it will
thicken up, or you can add
more grout. Stir until
smooth. |
 |
|
step TEN
We suggest that you use
Gloves when working with
Grout. It is non-toxic, but
it can dry your hands out.
You can easily go through 2
or 3 pairs of Gloves while
grouting. Apply the grout
with your fingers as
pictured. It is sorta like
icing a cake with your
hands. Press it down in the
spaces between your pieces.
Sculpt it on your edges to
make a nice smooth edge.
Generously cover your entire
piece. |
 |
|
step ELEVEN
Once you have covered your
entire piece and filled all
of the spaces, wipe off as
much of the excess as you
can with a plastic spatula
or piece of wood or your
gloves or hands.
Try to remove as much
grout as possible. If you
don't get it off now, it
will be much harder to do so
later. |
 |
|
step TWELVE
Now, take a very slightly
dampened sponge or cloth and
begin wiping the grout off.
After you do this you are
going to let it sit for
30-45 minutes or until the
grout residue becomes hazy
on the piece.
You can then use a dry cloth
or your hands to remove the
remaining haze and residual
grout. Clean each tile if
you desire. Do not use paper
towels, they flake off and
stick in your grout. |
 |
|
step THIRTEEN
You are done with your
grout. Throw it away. Never
wash it down the sink or any
drain! If needed, take a
cloth or sponge and polish
your piece up. If you did
not mosaic the edges of your
piece, you can finish it
with an acrylic that matches
your grout. |
 |
|
step FOURTEEN
Enjoy your new masterpiece! |

Mosaic Questions
This is our page of frequently-asked
mosaic questions. It contains
much of the information we have
concerning mosaic materials and
techniques, grouts, glues, mosaic
tables, outdoor mosaics and related
topics.Legal Disclaimer

What safety precautions do I
need to take?
Making mosaics requires basic
shop safety practices: Wear
goggles when cutting mosaic
materials or mixing grout.
Mosaic materials are often sharp.
Keep out of reach of children.
Avoid breathing the dust when mixing
grout. Wear rubber dishwashing
gloves when grouting to avoid
irritating your skin. Don't
overload patio tables with mosaic
materials so that the table becomes
unstable (top heavy). You
should also make sure that the table
frame can support the overall
weight. Return
to Top 
How do I start mosaicing right
now?
Glue tiles to a clean surface
one at a time with Weldbond. Make
sure the gaps between the tiles are
about 1/4 inch or less. After the
glue cures for 24 hours, grout the
mosaic with regular bathroom tile
grout. Return
to Top 
How do you grout a mosaic?
Mix the grout
according to
instructions on package and avoid
breathing dust. Spread the
grout into the cracks. Wipe off the
excess grout. Use a sponge instead
of a rag because the rag will catch
on any sharp edges. Don't try to
wipe it perfectly clean all at once.
Rinse out the sponge after each
pass. Make sure your sponge
isn't dripping water after you rinse
it out. Wipe flat across the
surface. Don't rub down in the
cracks or you will erode the grout
between the tiles. Keep the
surface damp as the grout cures or
it will crack. Return
to Top 
Can I mosaic on wood or plywood?
Indoors, these materials can be
used with no problems. Outdoor
use requires some thought and
preparation, and I would definitely
choose solid wood over plywood if
possible. You should seal the top
surface with a dilute solution of
Weldbond before you begin applying
tiles. I think most people mix
3 parts WeldBond
to 1 part water.
I would seal the back and edges with
water seal or an oil-based paint.
Fine mosaic work takes an investment
in time and materials. It only
makes sense to mosaic on a backing
that is resistant to moisture and
decay. Thus the best material
to use for a backing is concrete
backer board, especially for outdoor
tables and flooring. Concrete
board is cheap, available locally,
easy to cut and resists the
elements. However, wood and
even plywood make great backings for
small indoor mosaics such as mirror
frames and wall plaques.
Return to Top 
How can I learn about grouts and
how to grout?
Not much to learn. It's
the same techniques and material
used for bathroom tile. Ask at you
local building material store. Look
at a basic book on home improvement.
Return to Top 
Is there anything special about
mosaic grouts?
No. The grouts and sealers
you need are the same ones used for
ordinary bathroom tiling, and the
techniques of applying are the same.
Return to Top 
What is the best glue for
mosaics?
Weldbond. It's water based, has
no fumes, dries clear and water
resistant, bonds to most any
surface, is non-toxic and cleans up
easily. Return
to Top 
How do I use round marbles and
stones in mosaics?
If you're pushing them into wet
concrete as you would for a stepping
stone, then no problem. If you are
gluing them to a surface and then
grouting, make sure you use
something thick and tarry like
Liquid Nails brand adhesive. Also
make sure that you use thicker tile
around the marbles so they don't
stick out so far. Otherwise there is
a danger that the marbles may pop
off when you grout. I always wear
dishwashing gloves and grout with my
fingers. This allows me to remove
all excess grout without bumping the
marbles too much. Return
to Top 
What's the best glue for marbles
and round stones?
Liquid Nails brand adhesive.
It's thick and tarry and tends to
grab onto the round surfaces. Return
to Top 
What's the best adhesive for
outdoor mosaics?
Liquid Nails Adhesive. It's
thick and tarry and bonds to
anything, but it is solvent based
and the fumes are an issue. I use
Weldbond adhesive for mosaics where
water or rain isn't an issue because
there aren't any fumes and clean up
is much easier. I have used Weldbond
successfully on several outdoor
projects, but these pieces were
grouted and sealed very well, and
they were vertical surfaces that
didn't have water standing on them.
Liquid Nails Adhesive will probably
resist extreme freeze-thaw cycles
better. Return
to Top 
How do I put a mosaic on a wall?
Won't the tiles slide off while I'm
gluing them?
Glue your mosaic tiles to
fiberglass mesh at your work table.
When that is dry, glue the whole
thing to the wall and allow to dry.
Most people cut the mesh in smaller
sections, usually 12 inch x 12 inch.
Then you can grout in place. Return
to Top 
I grouted my mosaic and then
noticed that glue was showing. What
did I do wrong?
You need to always clean up
excess glue before you grout. I also
use the following technique when
using Weldbond indoors or outdoors.
After the glue has dried for a day
or two, I come back and mist the
mosaic with water. After about 10
minutes, any traces of glue that are
sticking up on the sides of the tile
will start to turn white. I then
take a razor knife like a box cutter
or exacto knife and trim away the
excess glue. This means that when I
later grout, there will be no glue
sticking up and not covered by grout. Return
to Top 
I grouted my stone mosaic and
now all the stones are the same
color as the grout. What can I do?
You should always seal stone
tiles and unglazed ceramic tiles
with a tile and grout sealer BEFORE
you grout. This is necessary for all
porous materials that can be stained
by grout. You should seal using a
Stone Enhancer instead of tile and
grout sealer if you want to darken
and enhance the natural color of the
stone. Both of these products are
available at local building material
stores. Ask there. For a stone
mosaic that is already stained, you
might want to try some of the
muriatic acid that contractors use to
clean cement from bricks. Also ask
at the building material store about
this product. Return
to Top 
How much grout do I need for my
mosaic?
How much grout you need depends
on three things: 1) the area of the
mosaic = L x W 2) the thickness of
the tiles and 3) the gaps between
the tiles. If the
tiles well-spaced
(all gaps under 1/4"), then you
should be able to cover the entire
mosaic of 18" x 18" with 2
lbs of grout. This is assuming your
tiles are under 3/8" thick. I
always set my mosaic on an old
shower curtain or piece of plastic
to catch all the wet grout
that
falls off the side as I'm spreading
it. That way, I can scoop it up and
use it. Otherwise you need a lot
more grout because most is wasted.
Return to Top 
What color grout should I use in
my mosaic?
I always choose a grout color
which contrast the colors of the
mosaic tiles so that the design is
highlighted. Otherwise the
individual tiles are lost to the
eye, and the mosaic looks more like
an ordinary picture and less like a
mosaic made from pieces. I avoid
situations like gray grout with gray
tile. A nice red-brown grout works
better in that instance. The key
concept is color contrast. Return
to Top 
Can I use stone and glass mosaic
tile together?
The two materials have different
thickness. If you are pushing the
tiles into concrete or mortar, then
it doesn't matter. If you are gluing
to a surface, the difference in
heights will be visible. This makes
grouting a little more difficult,
but it hasn't stopped me from doing
it on many of my pieces at the
gallery. I wouldn't recommend this
for floor mosaics! Return
to Top 
Can I mosaic wooden furniture
for outdoors?
Only if you don't care whether
or not it lasts. Mosaic on concrete
or concrete backer board. Concrete
backer board can be purchased
cheaply at local building material
stores and can be used as the mosaic
surface in metal patio tables. This
is the best way to make an outdoor
mosaic table. Return
to Top 
How do I make a mosaic stepping
stone? Do I need grout or glue?
No. Most mosaic stepping stones
are made by pouring concrete into a
mold and pressing in mosaic tiles
while the concrete is still wet. You
can get ordinary concrete mix from a
local building material store. Make
sure you pick out most of the
larger rocks before you mix it. You
can use a plastic dishpan as a mold
or cut off a plastic 5-gallon
bucket. Make sure you rub Vaseline
into it so the stone will come out
later. :) Pour the concrete about 2
1/2 to 3 inches thick. Don't buy the
stepping
stone kits. They are boring
and unoriginal. You can make
beautiful
stepping stones
just by collecting
your own marbles, beach glass,
shells, etc. Return
to Top 

Do I need grout with sand in it?
If the gaps between your mosaic
tiles are greater than 1/8".
The sand reinforces the grout to
prevent cracking if the gaps are
greater than 1/8 inch. Return
to Top 
My grout started cracking and
crumbled. What did I do wrong?
You shouldn't let the grout dry
out as it cures. Lightly mist with a
spray bottle, but don't let drops
accumulate on the surface of the mosaic. Mix the grout according to
instructions. It should be like a
moist dough when you start with no
dry material or lumps. Return
to Top 
How do I make an outdoor mosaic
last?
After the grout cures for 48
hours, seal the mosaic with tile and
grout sealer from a local building
material store. Return
to Top 
How do I cut glass and glass
mosaic tile?
You need a wheeled glass
cutter.
It has two blades shaped like
wheels. A regular tile nipper tends
to crush most glass but can be used
with certain types of vitreous glass
mosaic tile. Return
to Top 
What tool do I need to cut
smalti?
Wheeled glass
cutter. It has two
blades shaped like wheels. A regular
tile nipper tends to crush most
glass. Return
to Top 
What tool do I need to cut
porcelain, china and other
dinnerware?
Porcelain Tile Nipper. Return
to Top 
What tool do I need to cut
ceramic tile?
Tile Nipper. Return
to Top 
Should I use thickset or thinset
for my mosaic?
I don't use either. If you are
making an artistic mosaic, you are
probably want to glue each
individual tile with
Weldbond
instead of trying to spread a glue
designed for putting a bunch of
bathroom tile on a wall all at once.
Return to Top 
Can I make a mosaic on top of my
Formica counter top?
People have done so, but if the
mosaic is an interesting design,
you'll probably want to take the
Formica off and use a base that is
sure to last. The engineer in me
hates the idea of wasting time and
material on something that might not
