This Play Book
  • Upon completion of this unit, the student will be
    able to
  • Correctly mix thin set
  • Calculate amount of tiles needed
  • Install tiles
  • Cut end tiles

3
Assumptions
  • Students work in pairs of their own choosing,
    with 6 pairs maximum
  • All materials provided for students
  • Student has been introduced to the 30X60 inch
    frame

Task 1 Introduction
Now that we have a basic understanding of the
tools and materials that we will be working with,
lets get right into the business of laying tile
specifically, mixing the thin set, calculating
the number of tiles needed, installing the tiles
and cutting end tiles.
6
Task 2 Clean Installation Area
Our first step is to clean our work area by
sweeping the work board. This is important
because you dont want debris to get mixed in
with the thin set that you will lay down.
7
Task 3 Check color pattern of tile
Depending on your aesthetic intent, you may want
to either incorporate or eliminate
irregularities. To do this, you may want to pull
tiles from several different boxes or ensure that
the tiles came from the same lot.
8
Task 4 Ensure Safety Equipment in use
Safety is important at any time you are using
tools, and tile laying is definitely no
exception. The thin set material can be a
powerful irritant to protect yourself from
damaging your eyes, lungs and skin, please be
sure to wear the safety glasses, safety mask and
latex work gloves provided. Safety glasses are a
must when cutting tile!

Task 5 Calculate the amount of water and thin set
needed
Conventional wisdom dictates that a 50 lb bag of
thin set and 1 gallon of water will create enough
mortar for a 100 square foot (10 x 10) area.
The area each of you is working in is 12.5 square
feet (2.5 by 5). How much water and dry thin
set will we need?
10
Task 5 Calculate the amount of Thin Set needed
To calculate the amount of thin set needed,
multiply the exemplary amount (50 lbs) by the
actual square footage (12.5 sq ft). Divide the
result by the exemplary square footage (100 sq
ft) to calculate x above, which is the amount of
dry thin set you will need.
11
Task 5 Calculate the amount of water needed
To calculate the amount of water needed, multiply
the exemplary amount (1 gallon, or 16 cups) by
the actual square footage (12.5 sq ft). Divide
the result by the exemplary square footage (100
sq ft) to calculate x above, which is the amount
of water you will need.
12
Task 6 Prepare the Thin Set
Using the drill mixer, mix the water and powdered
thin set until it achieves the consistency of
peanut butter, which means you should not be able
to pour it from the bucket. Read the direction on
the back of the thin set package for further
instruction. Once the correct consistency is
obtained let the mixture stand for 15 minutes.
During this interval, make sure that you have
enough ceramic tile to use all the thin set in
the bucket.
13
Task 7 Calculate the number of tiles needed
To calculate the square footage of the work
board, multiply the length by the width of the
space in inches and divide the result by 144.
Multiply the new result by 1.1. Example 30 x
60 1800 1800 / 144 12.5 12.5 x 1.1 13.75
square feet You will need 14 tiles for this
space.
14
Task 8 Determine which trowel is right for you
Because we are using 12 tile, well be using a
1/4 trowel. If we were using 9 tile, wed use
a 3/32 trowel. What size trowel do you think we
would use for 4 tile?
15
Task 9 Spread the Thin Set
Instructor demonstrates the proper motion and
angle of the trowel and thickness of the thin set
on the board. Students are asked to mirror
instruction with one tile in the center of the
board. Student removes tile checking that thin
set covers the entire tile.
16
Task 10 Install Center Tiles
Start in the cross () or center of the room
applying thin set with a ΒΌ trowel in each section
for only one tile. Slightly wiggle each tile in
place over the thin set making sure it is
embedded in the thin set. The tile should be
flush with the plumb line. Place a 1/8 inch
spacer between each tile. After placing the first
four tiles make sure all corners are square using
a metal square. Let the first four tiles stiffen
in the thin set by waiting 15-20 minutes before
laying the next set of tiles.
17
Task 11 Calculate size of end tiles
The wall (or ending) to your left/right should be
the first place to have an end tile the last
tile laid in this section would be the upper
left/right hand corner. Cuts against the wall or
at the end should be measured by flipping the
tile over, back facing up and mark the tile for
cutting allowing for room to grout. The tile
should be cut so that it is flush against the
wall.
18
Task 12 Cut tiles
Place tile to be cut on the last tile set. Place
marker tile on top, against the spacer tile at
the wall. Trace the edge of the marker tile onto
the tile to be cut. Place the wheel of the tile
cutter on top of the cut line, then move the
wheel back to the far edge of the tile. Pull the
cutting wheel toward you to create the score.
Lift the cutting wheel and lower the handle
quickly to snap the tile along the scoring line.
19
Task 13 Complete the board
Now finish your board portion. Please come to
see me if you have any questions about the
procedures or materials we just covered.

Task 15 Transition to Grouting
Excellent job! We are well on our way to
completing this job. Since it takes at least 24
hours for the thin set to dry, well break here
and pick up where we left off in the next class.
Please be sure to put all of your tools and
materials away.
