Waterproofing is the combined name of waterproof engineering and concrete engineering. According to the experience of the waterproof engineering (QYETC) technicians, because the two types of engineering are similar in nature, the industry is generally referred to as waterproof engineering and has now been extended to network APP software. The external wall waterproof plugging project has a very important position in our lives and is closely related to our life. A complete, high-quality building is a combination of many parts of the project, no matter which side is out of the loopholes, it will have a big or small impact on our lives, such as external wall waterproof plugging project. If a house leaks from time to time, heavy rain falls outside, and there is little rain inside, will you be happy if you live? Of course not, then next we will take a look at how the external wall waterproof plugging should be done.
External wall waterproof plugging concept
External wall waterproof plugging, in a narrow sense, is the construction of the indoor and outdoor water-proof construction of the building and the leakage of the inside and outside leakage area. Broadly speaking, this is a treatment for the treatment of space objects such as water repellent treatment and fluid and liquid trapping.
External wall plugging precautions
Precautions: Mixing materials are used along with, stirring good materials must be used before condensation; as far as possible to avoid construction under the hot sun, if the coating is solidified under the hot sun, it should be promptly added drying measures and wet curing, 0 °C Antifreeze should be added to the following constructions; when the material is stored, it should be placed in a dry place indoors. After the material is removed from the bag, the excess material should be tightly closed and not exposed to moisture.
External wall waterproof plugging construction preparation
tool:
Surface cleaning tools: cutting/chisel, hammer, wire brush, broom, rag
Picking and dosing tools: bench scales, buckets, weighing buckets, stirrer coating tools: rollers (for coating thinner materials), brushes (for coating thicker materials and small areas).
condition:
Cannot be constructed below 5 °C and above 35 °C and in rain
Should not be constructed in a particularly humid and unventilated environment
External wall waterproof plugging construction technology
1, grassroots processing:
Cleaning treatment: Remove surface waste, yellow sand, stones and other waste, keep the site clean, stable, smooth, no dust, no oil. The base surface must be smooth, firm, clean, and clear water. The unevenness and cracks must be leveled first. The leakage must first be plugged and the yin and yang angles should be rounded.
Strengthen the treatment: whereever leaky parts and node fine cloth structure, such as: through the wall, wear plate, pipe root, gutter, gully, gutters, expansion joints, tiger windows, Yin Yang angle must first use type I products The proportions are mixed and coated with agitation and a synthetic fiber non-woven fabric is applied for reinforcement treatment. There must be no sanding, honeycombing, sand holes, holes, and cracks.
Roof construction: The roof below the waterproof layer should be constructed in accordance with the relevant construction specifications.
2, ingredients:
Pour the liquid into the mixing tank first, then pour the powder into the liquid and stir until no agglomeration of small particles occurs. During the high temperature, a small amount of water can be added (control within 5% of the liquid weight). Larger projects must use mechanical agitation.
The paint color powder should be mixed with the liquid and then dissolved with the powder. Prepared waterproof paint should be used within 45 minutes, with the use of.
External wall waterproof plugging traditional construction method
Leaking water in the building indicates that the waterproof layer is treated. The waterproof layer has hard tiles on the outside. According to the traditional method, the outside tile is split, the waterproof layer is opened, the waterproof layer is newly made, and the tile is re-laid. . Which labor costs, material fees, the time spent on the consumption is very large.
External wall waterproof plugging latest method
Waterproof trapping, the traditional concept is where to fill where missing. The latest waterproof trapping method is to abandon this traditional concept, waterproof layer leakage, waterproof leak-proof work on the outside of the tile, as long as the outer surface of the tile is waterproof, waterproof effect is the same.
External wall waterproof plugging construction method: use a knife to remove the waterproof cement or glue between the tiles and the tiles, dry the floor with a dryer for a day, then fill the gully with the same color of cement on the floor (the ground is white Fill it with white cement. The floor is black. Fill it with black cement. This is done for indoor beauty.) Then use a special CPC water repellent to slowly inject into the cement for 1-2 days. The agent and cement are firmly absorbed on the tile, effectively forming a solid waterproof layer.
Editor's summary: The above is the external wall waterproof plugging construction craft warm Tips: Housing plugging election to the teacher only peace of mind related to the introduction, hoping to help meet the needs of the friends!
