How to align a coupler
Ideal flat floor has both aesthetic and practical function. On the first point is clear - a noticeable unevenness eye spoils the impression of the interior. The second more significant: only normally lie flat floor covering (laminate flooring, etc.) and will stand furniture. Therefore, your task - to make a smooth screed, not pour incomprehensible "Concrete Wave" on the floor.
You will need:
- primer; - Roll; - Cement-sand mixture; - Gidrouroven or laser level; - Beacons (metal profiles, boards, beams, metal pipe); - putty knife; - Rule (special tool for leveling the surface).
Instruction how to align a coupler
The first and most important step - to determine the unevenness of the floor using gidrourovnya or laser level and find the highest point. Then, proceeding from it, vymeryat floor level around the room and make a mark on the walls, then to verify the correct installation beacons. Measures the floor gently, slowly. It is best to double-check the result, not to make a mistake, correct, which will be very difficult.
To tie grappled with the floor surface, it is necessary to cover the primer. Apply an even layer of the mixture is better with a roller. Do not try to fill the primer holes in the floor - it is not designed for this purpose.
After the primer has dried, it is necessary to install beacons. The installation will start from the highest point of the floor. It is best to mount them on small "handful" of the same cement-sand mixture, which you will fill screed. To do so, make a final mixture of slides along the whole length of the future beacon, and then push them in it to the desired level. The distance between the beacons should be 0.6-0.8 m. This is the most tedious part of the job is completed, and after drying sand concrete can proceed to the main stage.
Mixture for the screed must be in consistency as the estimates. Begin work necessary to the far end of the room. Carefully pour the mixture between the guides, distributed throughout the volume of the spatula. Make sure that there are no voids. Having laid about 1 meter of screed, you must align the surface of the beacons using rules, removing the excess. Dub is necessary to smooth movements, with a decent effort since the work with cement mixture always physically difficult. The material on the floor lay a better margin to only remove the excess, but not close up the remaining void. After controlling the first section, fill the new portion of the mixture and again align. So, repeat until, until the entire area of the premises will not be processed.
When the screed is dry enough to sustain your weight, you must remove the beacons, to put it simply - they break out, and immediately pour the resulting solution cavities, leveling the surface of the rule. Lighthouses in any case can not be left in the screed, even if the design you feel safe - a few months of operation, they will "walk" and cracked surface gradually. If done correctly, the result after drying screed you get a perfectly smooth durable cement floor.
