In this article you will find detailed step-by-step instructions with photographs for finishing the cellar. We will tell you about the most technologically advanced and convenient way to cover the floor, walls and ceiling of a two-level underground of a private house. The article contains a description of the process and order of work.
Premises below ground level are laid during the construction of new houses in 90% of cases. It is logical that you should not miss the useful space, and even with a constant temperature and humidity regime. We will describe one of the options for a beautiful and durable finish for such an underground.
Initial data and features of the object
This option is notable for the fact that it has two levels below the clean floor – a “dressing room” 1 m high and the cellar itself 2.4 meters high. Separate simple decisions were made for each of the premises. The walls of the lower level of the cellar are made of rough brickwork, so it was decided not to finish these walls. In addition, the brick has excellent thermal conductivity, which ensures a constant temperature in the basement from the ground.
Since all rooms are interconnected by passages in the floor slabs, it is these manholes that are the place for the combination and transition of different types – they should be located as exactly as possible one above the other. Then you can get by with one continuous staircase..
For work you need material:
- Moisture resistant gypsum plasterboard along the area of the walls and slopes of the hatch.
- Ceramic wall tile – the area of the walls of the intermediate room and slopes.
- Floor tiles – three floor levels.
- Tile adhesive – based on the total area (5-7 kg / m22), grout (0.2-0.3 kg / m2).
- Framed ceiling system (CD and UD profiles, dowels) and plastic panels – lower level ceiling area.
- DSP for the upper level screed – 30-50 mm (30-50 kg / m2).
- For tiles: tile cutter, wire cutters, grinder, hand mixer, buckets, spatulas, combs.
- Installation of plastic: impact drill, screwdriver, metal scissors, hammer.
- Control and measuring and marking: tape measure, level (laser), cord, markers, etc..
It is logical to divide all work into stages, observing the order of which, you can complete the work as quickly and smoothly as possible. In advance, you should sheathe the GKL intermediate room. This can be done either with glue or dry – with dowels.
Stage 1. Finishing the lower level ceiling
Since the height of the cellar is sufficient (2.4 m), the decision to mount plastic panels on the frame is quite justified. In this form, the ceiling “eats” only about 40 mm in height, which is quite acceptable. It is mounted in the usual way..
After marking with the level of the perimeter of the walls, draw a horizon line at the level of the plane of the frame (30 mm from the slab) and fix the UD guide profile. Screw the finishing plug for the panels to it.
Then cut longitudinal ribs from CD and insert into the UD guide with a distance of 400–600 mm. Fasten P-suspensions above them and tie them to the longitudinal ribs.
Install the cross-shaped fasteners of the frame, mount the transverse short ribs and tie the structure. Then mount the panels on self-tapping screws with a press washer.
It is better to sheathe the slopes of the manhole in advance. Install UD-strapping close to them and cut the gypsum board along the panels. This will give reliability in case of impact..
Mount the panels around the hatch with an extension. Most accurate trimming will be in place.
Trimming the panels is best done after the tiles have been laid on the slopes. The final touch – finishing the frame with a decorative corner on glue.
Stage 2. Installation of screeds
Since the intermediate level has a horizontal opening, it should be protected in advance to create a side of the inner slope of the screed. This is done simultaneously with the installation of beacons..
GKL slope on intermediate floor:
Then the screed is laid along the beacons in the usual way at both levels..
Stage 3. Facing the cellar floor
Since the floor was originally concrete (foundation), it was decided to make a final screed 40 mm along the lighthouses.
If the temperature in the cellar is not higher than +5 ° C, use a heat gun to dry the screed. Be sure to put something under the legs of the stairs so as not to spoil the screed..
Laying the tiles should start from the most visible edge, leaving a trim under the future equipment (racks, shelves). Tile rows are maintained in the usual way.
The “island” around the stairs should be done last. While the main plane freezes, you can proceed to the next stages.
Stage 4. Intermediate room
Here, the main difficulty is the linking of the slopes of the manhole and the floor finish, since the finish will be made of the same tile. With a certain skill of the tiler, it will not be difficult to tie the joint of the outer corner.
Alternatively, you can first lay the tiles on the floor, and then make the slopes. Don’t forget to have a decorative corner. The main trick here is to try to get around the hatch without clipping. If the pruning does happen, try to hide it in a decorative corner..
Another technique for “raw” vertical planes is to tape the tiles to the floor. So it will not slide under its own weight until the glue hardens..
Wall decoration is done after the glue has hardened on the floor.
It will be enough to paint the ceiling of the intermediate room with the composition Ceresit ST-116 (consumption 200-400 g / m2) or a similar paint with PVA and marble chips. In this form, the cellar will delight whenever there is a need to go down there. Easy-to-clean tile will keep it clean without much effort.
In the next article we will talk about how to tile the entrance to the cellar and install an invisible hatch.
