Upon completion of the waterproofing of bathroom and laundry room floors, whether the waterproofing system used consists of bitumen rolls or waterproofing paint Coating<\/span> Here, it is essential to ensure that the sealant is applied in two coats\u2014this is of the utmost importance. Once the sealant has dried\u2014that is, three to five days after application\u2014the plumber begins installing the drain lines for the sink, shower, bathtub, jacuzzi, and other plumbing fixtures, as well as the drainage lines for the air conditioners\u2014which is usually the responsibility of the HVAC contractor. All these lines are connected to the drain trap. The plumber may sometimes cut a small section of the waterproofing membrane when connecting the drain lines; in this case, the waterproofing contractor must be called in to perform a final inspection of the waterproofing work after the plumber has completed all his connections, If there are any defects or cuts in the waterproofing, they should be repaired. It is also recommended to lay a separating layer of fiber fabric directly on top of the waterproofing, as the fiber fabric protects the waterproofing from the backer board and also preserves the backer board. In the event of any water leaks through the tiles, the fiber fabric allows the water to pass through it, and this water flows by gravity into the drain through the additional openingin the drain created for this purpose. Fiber mesh is available from companies specializing in waterproofing as well as at building supply stores.<\/p>\n

With this, the waterproofing contractor completes the waterproofing work for the bathrooms and laundry rooms. It is also important to ensure that the warranty certificate for the waterproofing work is received from the contractor, noting that the warranty may be valid for up to ten years.<\/p>\n

Next, the tiler begins laying the floor tiles in the bathrooms and laundry rooms. First, the screed is applied, and care must be taken to ensure that the screed\u2014made of \u00abKankari\u00bb Zero sand\u2014is free of dust. When leveling the screed, care must be taken to ensure a slope toward the drain to guarantee that water flows directly into the drain.<\/p>\n

The floor level of bathrooms, kitchens, and laundry rooms should ideally be the same as that of living rooms and hallways; and there is no need to lower the floor level in bathrooms and laundry rooms by 1 or 2 cm compared to the level in living rooms and hallways, as the slope within the bathrooms ensures that water drains directly into the drain.<\/p>\n

If you wish to build a shower threshold 10 to 20 cm high, or to build a threshold later on top of the tiles using glass blocks, it is recommended to build a block wall and then plaster it, so that it can later be covered with tiles or other materials such as marble, depending on the floor design. It is not recommended to install the bathtub or shower before laying the floor tiles, because if there are leaks or water seepage between the wall and the bathtub or shower, it is difficult to control or repair the problem without breaking the tiles. It is best to install these fixtures (showers, bathtubs, and jacuzzis) installed over the tiles; there are many options and designs available. When installing marble flooring in bathrooms, white cement must be used. Also, if the tiles used for bathroom floors are large-format marble slabs, it is recommended to lay the floor tiles first and then proceed directly to installing the wall tiles.<\/p>\n

Floor tiles are installed using a cement mortar or tile adhesive. If the tiles are made of ceramic, terracotta, marble, or granite), it is recommended to install them using cement mortar; however, if the tiles are porcelain, it is recommended to first apply a rough skim coat to the floor, and once it has dried, install the tiles using tile adhesive.<\/p>\n

It is best not to use floor tiles larger than 30\u00d730<\/span> In fact, small and medium-sized tiles help achieve a good slope without negatively affecting the overall appearance, and the slope is not visible, unlike with large-sized tiles.<\/p>\n

At the same time, the tiler installs the drain, which is available in several sizes and types and is made of plastic, copper, and stainless steel\u2014the latter being the best option. They also come in various colors and designs in terms of shape and drainage mechanism, though it\u2019s worth noting that the colors of colored strainers may not last very long.<\/p>\n

The tiles are sprayed with water for at least four to five days when they are installed using a cementitious mortar, Afterward, grout is applied to the floor tiles. Note that grout is available in several colors, and there are also types of grout that are bacteria-resistant.<\/p>\n

With this, we have completed an important part of the interior finishing work: plastering, plastering the ceilings, and laying floor tiles inside the building. In the upcoming episodes, we\u2019ll discuss the exterior work on the building, including the facades and other related aspects.
