How to dismantle parquet that was glued to a gypsum screed?
Good afternoon, tell me where to start repairing practically unsuitable for use parquet floors (around the coating just fails). The apartment is on the top floor of a five-story building, built in the 60s of the 20th century. In one room I started to take off the parquet, it turned out that it was glued to a plaster screed reinforced with wood, that is, the so-called “shingles”. Well, I will remove the old coating, what to do next?
Based on the problem you described, its solution is at the initial stage in the complete dismantling of the old coating, as well as the dismantling of the old screed. Leveling the floor should be done using lags on which OSB boards are laid. As the final flooring, you can use any material, for example, laminate. Now let's dwell on the key features of the voiced pie cake device:
- A vapor barrier layer must be laid on the prepared base without fail. This will not allow wooden logs to absorb moisture contained in concrete walls and floor slabs. The vapor barrier is overlapped so that the strips overlap each other by 10-20 cm, the seams are glued with duct tape. The overlap on the walls is 10 cm.
- For logs, you need to choose a dry bar, with a moisture content of not more than 8-12%. In this case, the floor height should be at least 8 cm. And, therefore, a bar with a section of 40x50 mm is suitable for work.
- From the same wooden block, supports will also be made on which the logs will actually be fixed.
- You can not proceed with the installation of the lag before a level is set around the perimeter of the entire room.
- Seams between OSB boards and walls must be repaired with foam.
- Now it is possible to lay the final coating on the rough floor, since the laminate was first proposed as an example, then we recommend Tarkett brand products. Although here, of course, the choice is yours.
- Before laying the laminate, you need to lay a layer of substrate on the laminate. It eliminates minor defects of the subfloor.
In our opinion, the proposed option will be most optimal in your case. And in terms of material costs, and in terms of the load on the supporting structures of the house, because the building is quite old.
