How to seal him in the chimney at home?
1. Under the position where the flue needs to be blocked, cut a small wooden board and steel mesh, the size of which is similar to that of the flue you want to block.

2. Put the concrete under the steel bar and fix it with wire. Above it, the length of both ends of the steel bar with the diameter of 10 is 10 cm, and the spacing is 10 cm. Dust it on the concrete floor.

3. Fix the 6X6 angle steel on the wall with expansion bolts, then distribute the steel bars of Garden 6 at the horizontal spacing of 10 cm, tie them with tie wires, and pour the mixed concrete on the small boards, steel mesh and steel bars for compaction.

After a while, the chimney was sealed. That's how the chimney at home sealed him up.
