But this has been exacerbated by human activities which have led to: 1) an increase in greenhouse gas emissions that causes heat to remain trapped within the troposphere, and 2) a decrease in ozone in the stratosphere, causing less sunlight to be absorbed by the ozone layer, resulting in a cooling of the stratosphere.
When measuring for floor tile the rule is: Length x Width + Waste = Amount Needed. Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners.
2. Dry-fit the tiles on floor. Lay several porcelain tiles in a row, using spacers to simulate joints. Measure a 2-foot section of tile. Check the distance between tiles and note the location of the grout joint closest to the 2-foot mark on the tape measure.Write down the measurement.. Press each tile into the bed of mortar and apply firm pressure. Move the tile slightly from side to side to ensure its bond. Align each tile with the pencil lines and adjacent tiles.
