| Wall paint to do home improvement paint selection techniques (two) |
Part2: quality inspection of water based coatings
1, look at the appearance
Wall engineering to do the home improvement paint selection techniques
Look good paint should be no water tank, no starch, no rust, no mildew.
2, look at the stratification
Wall engineering to do the home improvement paint selection techniques
See the water solution of water in storage for a period of time, there will be a stratified phenomenon, the upper 1/4 is a water quality solution, the lower layer for the paint particles. To observe whether the water quality solution is colorless or slightly yellow, clear and clean, less floating. Poor water solution is more cloudy, and there are more floating.
3, look at the stirring
Wall engineering to do the home improvement paint selection techniques
Look at the paint particles to the desirability of a small amount of paint into the water and stir gently to observe the water is still clear, paint particles is uniform in size and in water is relatively independent, no adhesion phenomenon. The poor quality of the paint will be immediately cloudy, the size of the particle size differentiation.
4, look at the wash
Wall engineering to do the home improvement paint selection techniques
See the film coating should be off powder, and has a certain resistance to washing, dirt can be washed clean. Quality products with a damp cloth, coating color bright as new, and inferior products wash a few times, the coating is fading or breakage.
5, look at the test report
Wall engineering to do the home improvement paint selection techniques
See test report of the products shall be consistent with the synthetic resin emulsion paint national standards "and" interior decoration materials, interior wall paint hazardous substances limited standards "requirements, testing agencies shall be with the approval of the State Bureau of technical supervision, with CMA. |
