STEP-BY-STEP INSTALLATION




LAYING A TILE FLOOR.



New kitchen. Step-by-step report. Part 2.


Part 2 of 'To spot the expert, pick the one who predicts the job will take the longest and cost the most.'

Murphy's Technology Law #27 1/2.

 

The original flooring in the home was sheet vinyl. In just three years it had become gouged, stained and badly worn. The first step was to cover the entire floor with 3fs-in. plywood. The plywood subfloor was securely fastened with 1 3/4 steel drywall screws driven every 8-10 in. It's important that the subfloor be perfectly flat and smooth.


Next, we snapped chalk lines to form a grid of 2-ft. squares. These layout lines establish the pattern and ensure that the tiles
are laid perfectly straight especially with more difficult but much more interesting diagonal pattern. Before snapping the lines, the best place was chosen to center the pattern. For this job, it was centered on the 22sq.ft. center area where the kitchen island was planned. This created a visually balanced design leading to and from the front and side entry doors.

Next the mats were unrolled, cut, folded, cut and folded again and holes were drilled thru the floor to have all 6 connecting wires from 3 mats to appear on the basement ceiling for the easy connection later. The same was done for the programmable thermostat floor sensor. At this stage to be sure everything is OK the mats continuity (for the ground wires) and resistance (for the heating wires) were checked with the electric meter. Next the measuring, sketching and taking pastures were done - just to know exactly where the heating mats are before the floor will be covered.

 

Instead of doing the installation in one step - we chose to do it in two - first to cover the mats and metal mesh installed everywhere were mats weren't with smooth finished thinset.

 

 

Two days later - tile installation started. 


 

 

 

The tiles were set in a bed of thin-set mortar. The mortar was again mixed in a wheelbarrow using a hoe. For each 50-lb. bag of
latex-modified mortar, about 1 1/2 gal. of water was added and then mixed  thoroughly and then we let it slake (rest) for about 15 minutes to allow all the chemicals to dissolve.
The mortar was applied to the subfloor with a 1/4-in. notched trowel. Each 50-lb. bag of mortar covers about 100 sq. ft.
The mortar was applied to one 3x3-ft. area at a time. Four tiles were pressed into the mortar along with smaller pieces, and then the adjacent 2x3-ft. area was mortared.

 

 

To maintain uniform grout joints, 1/4-in. rubber spacers were placed between the tiles.
Tiles that needed to be cut were trimmed to size with an electric water saw.
Both the standard cutter which we occsionally had to use and the water saw can be rented for about $10 and $90 respectively.
Once all the tiles were laid it was the time for the break - the area
was left undisturbed for 48 hours.
Then sanded grout was forced into the joints between the tiles with a rubber float. 
The directions on the grout packaging were read. In our case for the 50 lb. bag of grout we also decided to use 1 gal. of latex additive and mix it well. The latex will icrease me grout's strength and flexibility. W allow the grout to set for about 30 to 45 minutes (depending on temperature and humidity), then wipe off the excess with a special pad and a damp sponge. Once the grout has cured fully (about 21 days), seal all joints with a silicone-based masonry sealer.

 

 

THE NEW FLOOR LOOKS LIKE A MILLION BUCKS and so does the whole new kitchen

 

 


WHEN INSTALLING THE MAT(S):

 

  • DON'T CUT THE HEATING WIRE!
  • ONLY THE FIBERGLASS MESH CAN BE CUT, NEVER THE HEATING COIL!

 

 

MAINTAIN THE DISTANCE BETWEEN HEATING COILS! 

This is NOT OK:

 

1" IS THE ABSOLUTE MININUM. 2"-3" IS BEST.


Please remember: Electricity can be deadly and wiring done incorrectly can kill and start deadly and destructive fires even when "just replacing one small receptacle". 

 

YOU ARE DEALING WITH LINE VOLTAGE, not low voltage! 

 

NEVER EVER attempt to work or even touch the inside of the electrical components without being 100% sure that the power is disconnected!

 

If you are not an electrcian and if you have the slightest doubt about your wiring ability, please contact a licensed electrician and/or repairman before doing any diagnosis, repairs or installations. The products shown here are deemed SAFE and sound by various testing authorities but the wiring process can only be SAFE when done with safety precautions. Please read manuals and/or ask pros when not sure. Most of the simple installations shown here can be done by yourself or you can have someone qualified do it for you and THEN have the electrician check it and connect it to power.
