How to calculate screed

Read the instructions for laying any flooring, you will surely find a phrase that the basis for the installation must be dry, clean, smooth and durable. But how to get the most perfectly smooth horizontal surface, what will it take? But you need to do is just correct to make a screed floor. It was she, screed, will help to level the ground for laying the flooring and also makes it durable and solid.

Instruction

1. The screed must be done to any floor, be it laminate, parquet, linoleum, tile or array – only of tie can give your floor covering reliability and durability, and the comfort when walking around the house or office. The laying of the screed, regardless of material, require a specific calculation.
2. Define the zero level of the floor, in the room where the floor will be laid. This can be done with a special laser device of conventional construction or of water level. If you work with a level, you will need to move the level around the perimeter of the room and put a small mark which later will have to interconnect. Such lines will be considered as zero and can be used in the future in order to determine the horizontal plane.
3. Determine the location of the maximum floor height and, consequently, the level of elevation. Measure the distance from the zero level to the floor in different places and write with chalk on the wall of each measuring point by specifying its exact value. So, the smallest value – this is the high point of the floor, and the largest, respectively – the lowest.
4. Subtract a larger number from a smaller and you will get the difference, which will be the level of elevation of your floor.
5. Make calculation regarding the amount of the mixture. So, for example, you need to put 25 mm of screed on our entire amount. The average consumption of your mixture (you can read on the packaging) is 2.2 kg per square meter at a thickness of 1 mm. screed 25 mm Then you need to multiply by 2.2 kg. 55 kg. it Turns out Therefore, you find how many kilograms of the mixture will need 1 square meter. Next, take the size of its premises, for example, 20 and multiply the received number, that is, 55.
6. Thus, it appears 55*20=1100 kg of the mixture you'll need a hair tie in your room. Generally, manufacturers provide a dry mix in bags of 25 or 50 kg, and consequently, we have obtained 1,100 kg divided by the number of pounds in a bag (1100/50=22) - you'll have a number of bags of dry mix that you will need to purchase for laying ties of a thickness 2.5 cm
