How do you waterproof an open air balcony? What is the best waterproof for open air balconies?

If rigid waterproofing raw materials are used to deal with water infiltration, it is difficult to achieve good results. The root cause of repeated leakage depends on the inappropriate waterproofing material selected. At this stage, a variety of cement-based waterproof architectural coatings widely used on the market are all rigid waterproof architectural coatings, which can not resist the cracking of the bottom layer, and the ground waterproofing itself will continue to cause gaps.

Because of the insufficiency of rigid waterproof architectural coatings, according to the method of adding elastic additives, to improve the crack resistance, it is called flexible waterproof coatings, and the roots or rigid materials will have gaps after a long period of time, and the problem of water seepage cannot be completely eliminated.

Therefore, from the perspective of resisting cracking, only elastic waterproof materials can be selected. At this point, there are other aspects that need to be taken into account. At first, the previous waterproofing of the ground was searched, and then it was removed and the datum of the balcony was treated.

Be careful not to leave any greasy, waxy, or other debris chemicals. Ensure that the datum is neat and tidy, once there is porosity or gap, it must be repaired first. Then, the ground leveling is carried out, and then the water stored in the moisturizing and replenishing layer below is discharged, and then multiple exhaust holes are set up to carry out exhaust pipe countermeasures.

If your balcony must be planted with some greenery, you should make a root barrier floor waterproofing. Root blocking ground waterproofing refers to polymer membrane root blocking ground waterproofing or modified material asphalt membrane ground waterproofing. According to the total area size of your balcony, you can choose which kind of ground waterproofing to do.

At that time, the southeast wall of the indoor staircase house was hit by the rain, causing the interior wall of the indoor staircase house to be blistered and peeled, and the interior decoration contractor proposed to replace the Zhejiang rooftop floor tiles and rebuild the ground waterproofing, or build a canopy, I took the latter and enhanced it to the environmental protection level. The whole process is simple, build a stainless steel pig cage on the rooftop, lay solar panels, pull wires on the wall to the power box, and complete the project in three days.

In the past, it was necessary to apply to the regional power bureau, but our home method is to purchase the power generation and surplus power grid, that is, the electricity that our family cannot spend automatically flows to the power grid and sells it to the power bureau. If under the premise of repairing landscaping, the ground waterproofing we should do must be a root-blocking waterproof layer, and the ground-blocking ground waterproofing has modified material asphalt membrane to block the ground waterproofing, and there is also a polymer membrane to block the ground waterproof; After doing the ground waterproofing, it is necessary to do the slope to solve, without leading to the flat roof part of the water storage, generally set the cement mortar leveling slope, the slope of the slope is not less than 3%; After doing moisture-proof, it is necessary to complete the irrigation test, and then carry out the maintenance and paving of the veneer brick decoration design to repair the upper edge.

1. First of all, you need to clean the balcony floor, if the ground is not cleaned well, it will affect the later effect. At the same time, in order to ensure the flatness, you can also do a leveling through cement mortar, because the balcony also needs to meet the needs of drainage, and you need to put water at the floor drain or drainage pipe according to the slope.

2. Then prepare the waterproof coating, brush the waterproof paint for the first time, and then cover the non-woven fabric after painting. Then paint the waterproof paint again, and also paint the walls of the balcony, about 30 cm from the ground. Wait until all the waterproofing is dry, do a closed water test to make sure there are no water leaks, and then you can lay floor tiles on the surface.

When laying floor tiles, it is necessary to leave a certain gap, and the gap can be treated by structural adhesive or tile adhesive.

1. Polymer waterproof coating.

This coating can be applied to outdoor balcony waterproofing, better increase the adhesion of outdoor outdoor balconies, good durability, strong adhesion, excellent weather resistance. Polymer waterproof coating is a green and environmentally friendly material that will not pollute the environment.

2. Acrylic waterproof coating.

The obvious advantage of this material is that the drying time is fast, and if you want to do a good job of waterproofing the outdoor balcony in a short time, you can choose this waterproof coating.

The open-air balcony can be made at the balcony to make a shed to protect from the rain, so that the child can be waterproofed, and it is best to use plastic film for waterproofing.

The open-air balcony should choose a good waterproof material, and a professional waterproof area should be created on the open-air balcony. You can choose double waterproofing according to the function setting.

<>1. You can choose waterproof coatings, such as a JS waterproof coating, because its biggest advantage is that Huaijing will not cause secondary pollution to the environment after environmentally friendly construction, and there is no harm. And after the construction is completed, a coating film will be formed, which has a certain strength, and the water resistance and weather resistance are very ideal. During construction, it doesn't matter if the ground is wet, it can be directly led and carefully constructed, which can bring better bonding effect, so it is more suitable for both the kitchen and the open-air balcony.

2. There is also a kind of waterproof coating is K11, the main ingredient is Bi crude acrylic emulsion, and some other added materials are added, including cement and filler, so the toughness and rigidity are very ideal. Whether it's a kitchen, bathroom or balcony, these are places that need to be waterproof and moisture-proof, and this K11 waterproof coating is more suitable for choice.

If the balcony at home is not waterproof, there will be water leakage in the future. So what should be done to waterproof the open-air balcony? PChouse will take you to find out.

When waterproofing the open-air balcony, it is best to let a special construction team carry it out, the effect is often more ideal, and try to choose products with higher waterproof performance. Its design can be designed by the owner or handed over to the decoration company to make the space planning more reasonable.

1. Find the original waterproof layer, because the waterproof layer is not exposed, it is in the lower part of the surface layer, it is necessary to carry out all the surface layers to find the original waterproof layer. After the original waterproof layer, level, drain the water stored in the original lower insulation layer, and set up some exhaust holes to drain the water in the insulation layer. After the waterproof layer is done, it is necessary to do the slope treatment, do not form the roof part of the water storage, usually set up cement mortar leveling and slope, and the slope of the slope is not less than 3.

2. If in the case of beautification, the waterproof layer we need to do is necessary to be a root-blocking waterproof layer, and the root-blocking waterproof layer has a modified asphalt membrane root-blocking waterproof layer, as well as a polymer membrane root-blocking waterproof layer. After the waterproofing is done, it is necessary to carry out a closed water test, and the water is not leaking, and then the maintenance and decoration of the veneer bricks are carried out. In the end, in the case of beautification and civil engineering cross operations, try not to damage the waterproof layer of the lower part, and once damaged, it should be repaired in time.

House waterproofing is divided into indoor waterproofing and outdoor waterproofing. When there is an open-air balcony in the design of the house, we can enjoy the moon on the balcony, eat and rest. Therefore, for open-air balconies, waterproofing is very necessary.

So, if you do waterproofing outdoors such as an open-air balcony, how should you operate it during the renovation period? The following are the waterproofing specifications and practices for outdoor waterproof open-air balconies.

The waterproofing material must be impermeable structure. The functionality of the waterproofing material must comply with the provisions of the current national standards and must include a product certificate. The outer surface must be flat and free of abuses such as hollowing, sanding, and cracks.

The moisture content of the lower layer must meet the structural requirements of the waterproofing material. Outdoor waterproof impervious layer must extend from the ground to the wall 250 mm from the ground. The impervious layer on the walls of the bathroom must not be less than 1800 mm.

The screed of waterproof cement mortar is closely related to the foundation and does not have an empty shaft. The appearance is smooth and shiny, no cracks, polished, and the yin and yang corners are round. The impermeable layer of the coating film is evenly coated with a satisfactory thickness to meet the requirements of product proficiency.

As a rule, the thickness is not less than and the bottom is not exposed. Outdoor waterproof construction joints must be ground along the direction of water flow, and the overlap width shall not be less than 100 mm. When using two or more layers of fiberglass fabric, the width should be offset by half of the width.

The appearance of the coating film is not blistered, there is no flow, there is no flatness, the joints of pipe fittings, sanitary equipment, floor drains and drains are impermeable, the head is smooth and will not fall off. The thickness and strength of the protective layer of cement mortar must meet the planning requirements, and it is strictly forbidden to damage the sealing layer during operation. After the outdoor waterproofing project is completed, a 24-hour water storage test is required.

First of all, the impermeable original layer is found, because the impermeable layer is not exposed, it is in the lower part of the surface layer, it is necessary to completely remove the surface layer and find the origin of the impervious layer. Once the impervious layer is removed, the water stored in the lower insulation layer will be drained horizontally, and ventilation holes will be set to drain the water from the insulation layer. If in the case of repair and beautification, we need to do impervious layer is necessary to block impervious layer, barrier impervious layer with improved impervious layer asphalt roll and impervious polymer layer.

Once the waterproofing layer is completed, the slope treatment must be carried out. It does not belong to the roof water. Generally speaking, the cement mortar is set at the slope level, and the slope is not less than 3.

Once the waterproofing is complete, it is necessary to carry out a closed water test and the watertightness is qualified, and then the repair of the aforementioned tiles and the maintenance of the decoration must be carried out. Finally, landscaping, in the case of off-road greening and civil engineering, try not to damage the lower waterproofing layer, it needs to be repaired in time.

The above is a brief understanding of the outdoor balcony outdoor waterproofing. It may not be suitable for everyone, but it can be understood that if you are doing waterproofing outdoors, you must choose a waterproofing material before construction. In outdoor waterproof structures, special waterproof materials are also required.
