In the Coating industry, constructability is a key performance indicator. It refers to the ease of use and operability of Coatings in the actual construction process, including Coating leveling, recoating, and absence of various construction problems. This article will discuss the importance of constructability, key factors, and evaluation methods.
The importance of construction
Coatings with good constructability can improve construction efficiency, reduce the operation difficulties of construction personnel, and speed up the coating speed of Coatings, thereby saving time and cost. The constructability of Coatings directly affects the uniformity and mass of the film. Excellent constructability can reduce defects in the construction process, such as sag, wrinkling, shrinking, bleeding, etc., thereby ensuring the conformity and good appearance of the film. Coatings that are easy to apply make it easier for construction personnel to master the construction skills of Coatings, reduce the possibility of operation errors, and improve worker satisfaction and construction mass. By reducing the incidence of construction problems, Coatings with good constructability can reduce repair work and Coating waste, and reduce the cost of the overall Coating project.
Key factors of constructability
Leveling
Coating leveling refers to the ability of the coating to levelling itself and form a uniform film after construction. Excellent leveling can reduce the uneven phenomenon of the Coating surface and provide a smooth film.
Recoatability
Recoatability refers to whether the Coating is easy to carry out secondary coating after drying. Good recoating sexual suggesfeseness Coating can be carried out without adhesion problems, and the repeability coating improves the convenience of construction.
Construction resistance
Excellent Coatings should have the performance of Sag resistance, anti-wrinkling, anti-shrinking, anti-bleeding and anti-biting. These performances can reduce the bad phenomenon in the construction process and improve the construction mass.
Evaluation method of constructability
In order to assess the constructability of Coatings, one of the following methods can be used:
Large area brushing test
According to the provisions of GB/T 6753.6-86, use a brush dipped in Coating to make a coating plate, and at the same time make a standard sample reference plate. Then, compare the disappearance of brush marks, sag, cissing, loss of edge, wrinkling, blooming and other phenomena between the two to evaluate the constructability of Coating.
Standard sample comparison
The workability of coatings can be quickly evaluated by comparison with standard samples with known performance. Standard samples should have known leveling and resistance to construction problems performance and can be used as a benchmark for comparison.
Construction site observation
In the actual construction site, the construction performance of Coating on the wall, ceiling or Miscellaneous surface can be observed. By observing whether there are problems such as sag, wrinkling, bleeding, etc., the constructability of Coating can be preliminarily evaluated.
Constructivability is a crucial performance indicator in the Coating industry, which directly affects construction efficiency and construction mass. Understanding the key factors of constructivability and adopting appropriate evaluation methods will help to select Coatings suitable for specific projects and ensure the smooth progress of the construction process. For Coating manufacturers and construction units, focusing on constructivability research and testing can improve the market competitiveness of Coating products, meet customer needs and achieve sustainable development. Therefore, the importance of constructivability cannot be ignored and should receive more attention and research in the Coating industry.
