Increased humidity, temperature fluctuations are the reason for the occurrence of cracks, drying the parquet. There may also be a loss, as separately taken rivets of the parquet coating, so significant sections of the floor. In those areas in which the floor experiences an increased load, parquet can simply be erased.
To increase the life of a parquet coating will help change individual rivets of the floor. To do this, remove worn rivets, clean the floor of allotted debris and dust, and in the case of a wooden floor, new parquet rivets are nailed to it. To mask the hats of nails, they are compressed with pliers.
Dear friends, you can make a parking lot here.
If it is planned to replace large sections of the floor, repair work involves gluing the rivets with casein or carpentry glue. At the same time, the floor cycling is carried out only after the glue has dried. If the base of the floor is made of cement, the installation of parquet rivets is carried out with a heated bitumen mastic. To seal the cracks between the rivets, a mixture consisting of sawdust, carpentry glue, water and cement is made. This solution is heated to 50 ° C and the gaps are filled.
After the rivets are replaced and the cracks are filled, apply mastic or facing varnish. Before varnishing, it is necessary to make a cycle, during which the old mastic is removed. This operation is carried out with a rag moistened in a calcined soda diluted in water (2-3%). After that, the floor is washed with clean water and allowed to dry.
Finally, when the repair of the parquet coating is almost completed, it is grinded with sandpaper and subsequent cleaning. After that, they start to varnish. Before applying varnish, in 30 minutes, a primer of the parquet surface is carried out by nitrolak. Varnishing itself is carried out in 2-3 approaches. Time between applying layers should be 16 hours.
