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.

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.

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.

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?

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.

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.

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.

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.

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?

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.

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.

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.

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.

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 14 Assessment

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.
