Exterior wall waterproofing is a divisional waterproofing project that ensures the structure of buildings (structures) is not attacked by water and the internal space is not harmed by water. External wall waterproofing occupies an important position in the entire construction project. The external wall waterproofing project involves a number of external wall structures such as the basement exterior wall of a building (structure) and the exterior wall of a house. Its function is to prevent the leakage of rainwater, domestic water, and groundwater within the designed endurance period of a building or a structure. The erosion of the building ensures that the building structure and interior room are not defaced and provide people with a comfortable and safe living environment. What are the external waterproof construction solutions? What needs to be prepared? The following is a brief introduction of the external wall waterproofing construction plan, hoping to help those who have this need!
Facade Waterproof - Kind
With the progress of society and continuous development of science and technology, there are a wide variety of exterior wall waterproofing coatings, which can be divided into silicone self-cleaning and water-resistant exterior wall coatings, strong acid and alkali-resistant exterior wall coatings, pure acrylic elastic exterior wall coatings, and tempered waterproof putty powder. , silicone self-cleaning elastic exterior paint, fluorocarbon paint, advanced acrylic exterior paint, outer wall oil tyrant, tile special primer, environmental protection exterior wall latex paint, ceramic tile finish, acrylic oil-based top coat, high weather resistance water surface Paints, metallic paints and other functional exterior paints.
Wall waterproof -k11 universal waterproof coating
In the outer wall waterproof coating, the most common is the k11 universal waterproof coating, which is a kind of two-component waterproof material combined with high-molecular polymer emulsion and inorganic powder. The high-quality cement is selected. Quartz sand is polymerized with specific macromolecules to form a waterproof coating on the surface and penetrate the interior of the material to form crystals to block the passage of water to achieve a double waterproof effect. It is characterized by a rigid waterproof material that highlights the adhesive properties.
Exterior wall waterproof-JS waterproof coating
JS waterproof coating for exterior wall waterproofing is a kind of green environmental protection material, with the advantages of environmental protection, stable performance, long waterproof life, good aging resistance, convenient construction, simple operation, strong adhesion, etc., JS waterproof coating most of the basic color is White, with obvious heat reflection function, compared with the traditional black roof can play a better heat insulation effect, modulation into color, can be decorated and beautified the roof and exterior wall, overall performance is superior, is the current country Focus on the promotion of the new ideal environment-friendly waterproof material.
Exterior Wall - Acrylic Waterproof Coating
Acrylic waterproof coating for exterior wall waterproofing is a one-component water-emulsion waterproof coating made with pure acrylic polymer as the base material and additive, using the international advanced technology and raw materials. , It can be easily combined with the ground gap to form a strong waterproof layer. After brushing, it needs to be treated with pulling or sand blasting to increase its friction, and it is easy to tiling. It is especially suitable for use as a wall waterproof material.
Wall waterproof - polyurethane waterproof coating
Polyurethane waterproof coating for exterior wall waterproofing is a kind of internal and external coating, thickness is about 3mm, elasticity is more than 300%, no cracking will be caused by any base material in use, and the waterproof effect is excellent, but it also has its deficiency. Where, the smell of polyurethane waterproof coating is relatively large, and it is difficult for most people to accept. It requires the use of a scraper during construction, which is laborious and the operation is more complicated. It is a reactive moisture-curing film-forming waterproof coating. Can be used for roofing, exterior walls, non-potable water pools, retaining walls and other waterproof projects.
How to make waterproof outside wall
The waterproofing of the outer wall should first be cleaned and the surface of the grass-roots level should be compacted and leveled. When the leveling layer of cement mortar is used, it must be fully maintained. There should be no phenomenon of loose, sanding, and peeling, and the design requirements should be met.
Second, blowing dust,
In addition, the key parts are processed
In addition, the bottom brushing
Then, multi-pass waterproof coating
Finally, the coil is bonded
External Wall Waterproof Construction Scheme and Construction Specification Behavior
To prepare for the construction of the waterproofing of the exterior wall, first of all, the tools for construction shall be prepared thoroughly and fully, and the tools for the waterproof construction of the external wall shall be:
Motor vehicles, hair dryers, all kinds of roller brushes, washing buckets, paint mixers
External wall waterproof construction program Step 1: Check the wet.
First of all, check whether the building materials of the wall are missing, and see if it is even and even. If the material of the wall is missing, it shall be filled in time, and after the mortar ash is used, clean up some residual mortar ash on the wall. Next, the whole wall is moistened with water, and its wall is fully moistened.
External wall waterproof construction program Step 2: Coating.
Then I started to paint the waterproof coating on the wall, because according to the different paints used by each home, some paints that need to be mixed should be fully mixed, and some waterproof paints can be directly applied to the wall, which will save a lot of work. There is to pay attention to the thickness of the paint, according to the actual situation of the thickness of the paint to choose, the thicker the waterproof performance the better, but this will increase the cost of water-proof construction materials, so the thickness of the paint is just right.
External wall waterproof construction program Step 3: Check and repair.
After applying the paint, carefully check the completion of the entire construction to see if there are any missing or missing places. To see the evenness and flatness of the surface, be sure to make it smooth and smooth. Do not leave uneven surfaces. , This will not only affect the appearance but also affect its waterproof effect. There is also to be noted that some seemingly flat surfaces may have the phenomenon of cellular pockmarking, which requires a pressure plate to press hard during the coating to ensure the effective and close contact of the paint on the wall.
External wall waterproof construction program Step four: Keep dry and ventilated.
After finishing a series of external wall waterproof construction projects, the next thing to do is to properly protect the work done, and to make waterproof measures in the entire external wall, to prevent its just coated waterproof paint from being rainwater. Scour away, so keep it dry and ventilated so it can be molded early.
Editor's summary: The above is the experience of the external wall waterproofing construction program. Owners' experience sharing: The reasons for the leakage of the external wall of the building and the related introduction of control measures. I hope to help friends who have this requirement!
