Bathroom waterproofing is an important part of bathroom renovation. Making bathroom waterproof not only makes the bathroom look more beautiful, but also more importantly prevents the leakage of the wall in the future. Therefore, waterproofing the bathroom is very important. Here's a brief introduction to bathroom waterproof practices and some precautions.
Bathroom waterproof practices
One must deal with grassroots. First of all, to clean the construction site, if there are cracks or empty drums around the pipelines and floor drains, it is necessary to chisel into "V"-shaped grooves for repair and reinforcement. After the base surface is cleaned up, the entire area must be wetted.
Second, we must repair key areas. The seams between the wall and the ground and the joints between the sewers and the ground are the most prone to water leakage. Before the waterproofing, it is necessary to use kitchen and bathroom-specific repair mortar to make "r" corners. The treatment must be meticulous. There can be no sloppyness.
The third is the overall waterproof treatment. After the completion of the repair, the entire body should be painted with a durable waterproof paste for kitchen and toilet. In order to achieve better waterproof effect, the general bathroom wall to do about 1.8 meters high waterproof treatment, conditions are recommended to make full height, if it is a lightweight wall (such as plasterboard, etc.), must be full of high brushing The wall surface of the kitchen should be at least 0.3 meters high, and the water area for the vegetable washing pool should be 0.5 meters higher than the water outlet; the door frame and the threshold stone should also be brushed in place to prevent flooding.
Four to do water closure test. After the waterproof layer is solidified, all sewers shall be plugged and a "low wall" shall be built at the entrance for water injection test. The water injection height shall be around 500px. After 48 hours inspection, if there is no significant drop in water level, it indicates that the waterproof quality is qualified. Conversely, to find the leak, do a water-retaining test after repair, until qualified.
Toilet waterproof precautions
Waterproof height: Be sure to do waterproofing on the wall. Before waterproofing the walls, do waterproofing on the wall. In the general waterproofing process, the wall surface is to be waterproofed to a height of 30 cm. However, for a non-load-bearing lightweight wall, the entire wall should be waterproofed, and at least 60 cm in height must be achieved.
Waterproof smearing: The seam between the wall and the ground and the pipe seam between the upper and lower water are the most prone to problems. We must supervise the workers to handle these corners. The waterproof coating must be applied in place. .
Waterproof tile: re-floor tile to do the floor waterproof If you need to replace the original floor tiles of the bathroom, after the original floor tiles are chiseled away, you must first level the floor with cement mortar, and then do the waterproof treatment, this can avoid the waterproof coating due to the thickness is not Both cause leakage. Before you do waterproofing, be sure to clean the floor.
Waterproof mulch: Try not to damage the original waterproof layer. The waterproof layer is generally used on newly delivered buildings. Therefore, leakage will not occur if the original waterproof layer is not damaged.
Waterproof wall groove: The inner water pipe groove should also be waterproof. When the pipeline and floor drain pass through the floor during the construction process, the waterproof layer around the hole must be seriously constructed. Buried water pipes in the wall, so that a reasonable layout, the laying of water pipes will be greater than the diameter of the groove, smooth plaster groove, and then brush the groove waterproof coating.
Waterproof material purchase
The main cause of water leakage is due to the failure of the used waterproof coating, so the purchase of waterproof coating is especially important. At present, there are two types of waterproof materials on the market: one is polyurethane waterproof coating; the other is polymer cement-based waterproof coating.
Polymer cement base has become the protagonist of the waterproof coating market. Polyurethane waterproofing is the main force in the waterproof market. Waterproof performance is also available. The reason for its elimination is that it is not environmentally friendly. As one of the emerging waterproof materials, cement mortar is the material that is currently sold as fire. General waterproof materials are generally recommended for waterproofing kitchen and toilets. The earliest and largest application of acrylics was in environmentally friendly paints and coatings.
