When the epoxy floor paint builders checked the epoxy floor process early, they found that the strength and smoothness of the foundation floor were poor, but the surface did not crack and bulge. It is considered that only the old floor paint coatings need to be shoveled off and polished, and this polishing needs a little depth. In our life, epoxy floor paint is a more common type of paint, whether in the workshop of various enterprises, or in the classroom of various educational institutions, we can see its existence, it also has the advantages of anti-skid, dust-proof, so what problems should we pay attention to in the construction?
Key Points for Construction of Epoxy Floor Paint
1. The construction environment and materials to be transported to the construction site must be placed where wind, rain and direct light can be avoided. If the sunlight is directly exposed to the construction surface, the air ions contained in the basic layer or in the film which has not yet been completely hardened will cause small air holes due to poor discharge, so the whole window should be covered with newspapers or plastic sheets.
In addition, during the construction period, when the membrane is completely hardened, the ventilation areas such as doors, windows and crevices should be sealed with protective tape. At the same time, it is necessary to prevent the wind from blowing into the crevice from bringing dust. It should not be constructed under the environment of less than 5 C. If possible, heating or air conditioning can be turned on. When it rains, the open part should be closed to avoid dampness affecting the construction surface, but do not hinder ventilation.
2. Safety and health management requirements are also important. Personnel engaged in construction must be specially trained and have a certain knowledge of chemical products; during construction, they must wear work clothes, work shoes and anti-labor supplies; when various materials are accidentally touched on the skin, they sometimes damage the skin. They should be cleaned with soap as soon as possible, and seriously sent to the hospital for treatment.
All kinds of materials are not allowed to touch any moisture (except water-borne epoxy floor coating), because epoxy floor materials contain trace combustibles, fireworks are strictly prohibited at the construction site, and materials on the site are not allowed to be placed in places directly exposed to sunlight; construction tools should be inspected regularly, maintenance and cleaning by specialists; construction site should have clear standards. Understanding, no unrelated personnel are allowed to enter.
3. With regard to quality management regulations, before construction, construction technicians should confirm the following items: base area and base surface condition, select materials and construction structure, and be familiar with material specifications, proportioning and dosage.
After construction, the construction technicians should confirm whether there are any obvious defects such as smear marks, air holes, granules, orange peel, uneven color and other film defects, whether the color is the same as the sample, whether there is color difference, whether the film is hardened according to the normal law (simple judgement with nails); the construction personnel should strictly follow every step of construction. Public execution should find out the reasons for the anomalies and record them to prevent recurrence. If they are not solved, they should report to the technical personnel immediately.
How to Correctly Modify Epoxy Floor Paint
The use of epoxy floors is expanding, such as industrial plants, parking lots and other places can see the elegance of epoxy floors. Normal epoxy flooring service life is 5 - 8 years, and in the use of this period of time, attention should be paid to the maintenance of epoxy flooring. If, after years of careful maintenance, problems arise in the epoxy flooring project, it means that you should renovate the old epoxy flooring project. So how to carry out renovation and transformation?
Construction Attention of Epoxy Floor Paint
Not all old epoxy flooring projects need to be reformed, but mainly for the operation of some machinery and the rolling of many vehicles, resulting in a serious decline in the brightness of epoxy flooring paint. There are also some parking lot floors with severe scratches, so these areas need to be renovated with "heavy medicine".
For different degree of "injury", the strength of renovation and transformation is different. If the slight scratches of the old epoxy floor project are found on the surface of the epoxy material foundation, the strength, flatness and cracking of the foundation ground are good, but the surface is slightly damaged, the treatment method is relatively simple. As long as the surface of the old epoxy floor is polished, and then the surface of the old epoxy floor is cleaned up, it can be coated with epoxy.
