[for installing tile flooring and tile walls)
- How to Figure Out Square Footage
- How to Know How Much Tile to Purchase (once you have sq. ft.)
- How to Figure Out How Much Thin-set and Grout [setting materials] You'll Need
- How to Know How Much Hardi Board or Durock to order
Unknowingly experienced tile installers use formulas every day.Through experience we just automatically figure in our thinking of jobs using unnoticed formulas every day.It just dawned on me the other day on the job that I could share-some of these formulas to readers and it would help them understand more about what it takes to install tile and how to understand more about how to find a reasonable installer for their job.
1 .the first and foremost formula is the figuring of square footage
- the ft of the length multiplied by the ft of the width determines the total sq ft.
- for instance a 5 ft room length by 5 foot width = 25 total sq ft
- a 10 ft wide room by 20 ft long = 200 total sq ft room
2. After you know you sq ft of tile to be installed .you need to know how much tile to order.Generally you need 10%more tile than the actual area to be tiled to account for cuts and waste when installing straight line tile .If you are going to lay tile in a diagonal pattern you will need to add 15% more tile than actual area to be tiled because with a diagonal installation there will be more cuts and waste
3.The formula to figure setting materials grout and thin setis pretty straight forward. For every 100 sq ft of tile you will need 50 lbs of thin set mortar and 25 lbs of grout
4 .Hardi Board and Durock is generally sold in 3ft by 5 ft sheets= 15 sq ft per board. So you need 1 board of Hardi Board or Durock for every 15 sq ft of tile to be laid.It takes one half pound of nails to nail each board. So 1 lb of 2 inch roof nails for each 2 boards of 3 ft by 5 ft Hardi Board or Durock boards to be installed.
These are some formulas needed to understand basic tileinstallation . All tile installers even if unknowingly use these formulas every day when pricing and preparing for tile installation. Tile jobs are priced upon the sq ft of tile to be installed the sq ft of the Hardi board or Durock and the shape of the area to be installed in.
Other factors include:
- the materials to be installed , mosaic tile , marble or slate
- tiles are more labor intensive and cost more per sq ft to install than ceramic or porcelain tiles. Every tile installer has a different cost base according to their expertise,
- overhead,and how busy they are. Shop around, get references
- be comfortable with whomever you hire to install tile in your home.
- But most important remember tile in your home when installed correctly will be there for many many years so make sure from the beginning it is exactly the look you want!
