The construction of waterproof coating is a key step to ensure the waterproof function of the building, and the following is the general construction process:
1.Base Treatment:
Make sure the base surface is flat, clean, free of oil, floating dust, cracks and hollows.
For special parts such as yin and yang angles, it should be made into an arc shape or a 45-degree angle.
Check whether the base surface is firm and reinforce if necessary.
2.Preparation before painting:
Prepare enough construction tools, such as brushes, rollers, shovels, etc.
The waterproof coating should be prepared according to the proportion of the product manual, and stirred evenly.
Pay attention to the temperature and humidity of the construction environment to ensure that the coating can cure under suitable conditions.
3.Coating application:
Uniform application by brush, roller or spraying.
The coating should be applied in layers, and the application interval between each layer should be determined according to the product manual.
After the first coat of paint is applied, it is necessary to wait for it to dry completely before applying the second coat.
For overlapping parts and details, special attention should be paid to the continuity and uniformity of the coating.
4.Special Site Treatment:
The height of the waterproof layer in areas prone to moisture is generally not less than 500 mm.
The place where the pipeline passes through should be waterproof and isolated, and sealed with sealant.
Yin and yang corners, construction joints and other parts should be additionally strengthened.
5.Inspection & Trimming:
After the construction is completed, check whether the coating is defective, and if there are defects, they should be repaired in time.
Make sure that the coating is completely covered, with no omissions and no visible marks.
6.Acceptance and maintenance:
After the coating construction is completed, acceptance should be carried out to ensure that the design requirements are met.
After application, strong direct sunlight or water immersion should be avoided to ensure that the coating cures properly.
The cured coating can be applied or laid with other materials.
During the whole construction process, the construction requirements of the product manual should be strictly observed, and the relevant safety operation procedures should be followed. Different waterproofing coatings may have different characteristics, so they should be detailed and trained before construction to ensure the quality and safety of construction. If necessary, it is recommended to carry out the construction by a professional construction team to ensure the waterproofing effect.
