1.Inspect and Clear Roof Gutters: Ensure they function correctly to channel water away from the building.

2.Sealant Maintenance: Keep roof waterproofing and infiltration points properly sealed to prevent leaks.

3.Gutter and Drainage System Efficiency: Confirm that gutters and drain holes operate effectively and are aligned with the design specifications.

4.Roof Drainage: Ensure adequate drainage around the roof to prevent water from pooling and causing damage to the building structure.

5.Construction Project Planning: Carefully plan construction projects to maintain environmental openness (ensuring ventilation) by consulting multiple weather forecasts.

6.Piping System Inspection: Regularly check the piping system for damage or signs of potential failure.

7.Water Damage Assessment: Look for evidence of water damage and investigate the underlying causes.

Note: For extensive or complex water intrusion issues, professional intervention is recommended.

A: Calculating Waterproof Paint Requirements: The quantity of waterproof paint needed is calculated by multiplying the waterproof construction area by the paint application rate per square meter.

-Priming: Apply a waterproof primer at a rate of 0.3 to 0.4 kg/m².

-First Coat of Waterproof Material: Apply at a rate of 0.6 to 1 kg/m².

-Second Coat of Waterproof Material: Similarly, apply at a rate of 0.6 to 1 kg/m².

According to the manufacturer's instructions for various waterproof coatings, the theoretical quantity needed for two coats of application may vary. However, a general estimate can be made as follows (these are theoretical values; actual quantities depend on specific conditions):

1.Acrylic: The application rate is approximately 3 kg/m².

2.Polyurethane: The application rate is around 2 kg/m².

3.Polymer Modified: The rate is about 3 kg/m².

4.Elastic Cement: Also, approximately 3 kg/m².

5.Primer Addition: If a primer is used to enhance adhesion, adjust the estimat

1. Check and clean roof gutters to make sure they are working properly

2. Maintain proper sealant on roof waterproofing and infiltration

3. Make sure that the gutters and drain holes are working properly and planned according to the design

4. Make sure you have proper drainage around your roof so that the water does not leave the building

5. Carefully plan construction projects to keep buildings open to the environment (ensure ventilation) by using multiple weather forecast sources

6. Check the piping system for damage or signs of imminent failure

7. Look for signs of water damage and investigate the cause

Note: Large and complex water intrusion problems are best left to professionals.

A: The amount of waterproof paint = the waterproof construction area * the amount of paint per square meter.

Apply waterproof primer (Primer), use 0.3~0.4kg/m2 as unit

Coating the first layer of waterproof material, the unit usage is 0.6~1kg/m2

Coating the second layer of waterproof material, the unit usage is 0.6~1kg/m2

According to the instructions for the use of various waterproof coatings, the theoretical amount of materials required for painting two coats is different according to the specifications of each manufacturer, but generally it can be estimated as follows: (This is a theoretical value, the actual amount depends on the actual situation )

1) Acrylic: the dosage per square meter is 3 kg/㎡

2) Polyurethane: the dosage per square meter is about 2 kg/㎡

3) Polymer polymers: about 3 kg/㎡ per square meter

4) Elastic cement: about 3 kg/㎡ per square meter

5) If you need to add a primer to increase the amount of adhesion, you must increase the estimate according to the actual situation.

All kinds of waterproof coatings sold on the market, as long as they meet the national standards, should be used for home decoration and waterproofing. These coatings have their own advantages, and you can choose to buy them according to your needs.

Polyurethane waterproof coating has good elasticity and extensibility. In terms of coating film quality, it has the most outstanding comprehensive performance among all kinds of coatings, but the construction period is longer and the price is more expensive.

It is worth noting that most of the miscellaneous brand products currently on the market are not pure polyurethane, and the environmental protection performance is not very good; acrylic waterproof coatings are easy to construct, environmentally friendly, have better coating performance, and are moderately priced. They are generally used in home waterproofing. Coating; JS is a kind of waterproof coating combining hardness and softness, which is convenient for construction, environmentally friendly and non-toxic, and is also a good choice; waterproof mortar coating has high film strength and is well combined with the base layer, and can be directly pasted on tiles, which is economical and practical. However, because it is a rigid waterproof material, it is not suitable for the decoration of new houses that may have subsidence.

Generally speaking, among all kinds of paints, polyurethanes have the best performance, acrylic and JS paints are the most cost-effective, and mortar paints are economical and practical.

Judging waterproof materials mainly consider the following three aspects:

1) The paint should be free from precipitation, delamination and agglomeration;

2) No strong pungent smell;

3) Whether the construction is convenient.

Various waterproof indicators of waterproof materials, such as durability, deformation, impermeability and other parameters, have no direct relationship with whether it feels sticky or not. Some common counterfeit and inferior products are intentionally made sticky in order to enhance the intuitive experience, but the waterproof effect is actually very poor. The R&D and production of waterproof materials is a very professional and complicated process, and the quality of materials cannot be judged by the feeling of a single viscosity.

The exposed waterproof layer (such as: PU waterproof, acrylic paint waterproof and other elastic paint waterproof) basically has the advantages of cheap price and convenient and fast construction, but it often fails due to lack of experience in on-site judgment

The most important thing is that any waterproof material will accelerate aging if it is directly exposed to ultraviolet rays and nature. No matter how good the waterproof material you choose, it still cannot withstand the fact that the waterproof material will age.

Covering after waterproofing (such as emulsified asphalt, rubberized asphalt, waterproof blanket, etc.) will prolong the service life of the waterproof layer, which is why some old buildings use covered asphalt waterproofing. The cause of leakage has not been seen for decades or twenty years. However, adding covering protection on the waterproof layer has the disadvantage of relatively high construction costs, but it is worthwhile in terms of long-term economic benefits.

Waterproof coating is one of the indispensable materials in the modern construction industry. When decorating a house, the most feared thing is water leakage. So how to effectively select waterproof coatings, decoration and waterproofing, whether it is kitchen and bathroom, balcony, pool, roof, floor, interior and exterior walls, etc., waterproof materials must be used. So how to choose a good waterproof coating? The following describes the choice and quality of waterproof coatings.

1、For imported coatings, it is best to choose products with Chinese logos and instructions. Non-environmentally friendly waterproof coatings have excessive harmful substances, and most of them have pungent odors, which make people feel sick and dizzy. Therefore, we smell the smell when we choose to buy, if there is a pungent smell, we should consider it. It should also be noted that paints containing flavors must not be bought, because adding flavors is a chemical in itself, which is difficult to protect the environment.

2、After purchasing, please ask the seller to open it in person to check it out. If there is serious delamination after opening, it means that the quality of this waterproof coating is too poor; use a stick to gently stir the coating, lift the stick, and see if the waterproof coating stays on the stick for a long time or whether the coverage is even. If it stays for a long time and covers evenly, it means the quality is good, otherwise it is the opposite; dip a little paint on your hands and rub it with your hands to see how fine it is, the more detailed the better.

3、Under normal circumstances, the waterproof materials selected for the waterproofing of building waterproof materials are better, and of course they also have weather resistance and adhesion. Among the materials, we still recommend that you can choose waterproof materials. Carry out the materials in the thermal insulation of the auxiliary liner to complete the matching. At the same time, there are also relevant content proposed in the connection form required for waterproofing or heat insulation.

4、When the roof of the building is waterproofed, it is necessary to use a waterproof material with good weather resistance and temperature resistance. Because the waterproof layer in the roof does not set up an insulation house, of course, when the waterproof layer is exposed, it can be subjected to the invasion of the natural environment such as wind and rain for a long time and the deformation caused by the structure. Of course, for these often It is a relatively common natural phenomenon.

5、If it is said that in underground waterproofing projects, we can use waterproof materials that must have good anti-seepage ability or extension effect rate. Of course, the water permeability will not be affected, and it must be better. For these requirements, the groundwater is constantly eroding. Of course, the water is relatively large, and the deformation conditions under the structure are constantly raised.
