calculate tile boxes, adhesive and grout
On the Flooring tab choose the area source, the tile size, the layout and the m² per box. The tool shows boxes, adhesive bags, grout in kg and baseboard, and every coefficient can be replaced by the one on the data sheet.
You buy 13.2 m², with no box left over.
That is 39 pieces with 15% waste; the 7 boxes hold a little more.
108 ÷ 20 gives 5.4, rounded up.
900 cm² still falls in the 6 kg/m² band.
Fits one 5 kg pack.
A small tile uses less adhesive and more grout per m².
Take the net wall area, multiply by the coats and divide by the coverage. A 4 x 3 m bedroom with a 2.7 m ceiling, one door (1.6 m²) and one window (2.0 m²) has 14 x 2.7 = 37.8 m² gross and 34.2 m² net. With 2 coats at 9.4 m²/L that is 7.3 L, and 8.0 L with a 10% margin. The best purchase at the example prices is two 3.6 L cans plus one 0.9 L can, or 8.1 L. The coverage printed on your own paint can always beats the default value.
Manufacturers usually require back-buttering for tiles above 900 cm² and on facades. The calculator already uses the double-bed consumption (9 kg/m²) for tiles larger than 900 cm², and you can override the value.
It is included when the source is the room floors: perimeter minus the door widths, plus 10% waste, divided by the piece length. The default is a 0.60 m piece and the price is editable.
Yes. Choose the Walls source to use the net room area or Manual area to type the exact size of the bathroom or kitchen. The baseboard is only calculated for floors.
Floor 20 m², walls 43 m² (openings deducted: 5.6 m²)
Floor 10.5 m², walls 31.5 m² (openings deducted: 3.6 m²)
A door of 0.80 x 2.00 m is 1.6 m² and a window of 1.00 x 2.00 m is 2.0 m². Edit them to match your job. With the deduction off, the numbers are more generous.
