The cause of bubbles in the coating of epoxy floor paint due to uneven coating

The main reasons for uneven coating thickness during the application of light cured floor paint in the painting of wooden flooring are as follows.

The gap between the two sides of the spray screen blade of the coating machine is inconsistent, resulting in differences in the amount of epoxy floor paint sprayed, leading to uneven thickness of the coating film. The wear and tear of the shower screen blade or the blockage of impurities result in varying amounts of paint being sprayed, leading to uneven coating of the floor paint. Uneven heating before topcoat coating results in inconsistent viscosity of the paint, with low viscosity causing faster flow rate and high viscosity causing slower flow rate, ultimately leading to differences in the thickness of the epoxy floor paint coating.

There are usually three methods for floor paint companies to deal with uneven coating thickness.

Before applying floor paint, adjust the blade of the coating machine to be consistent on both sides. When the edge of the shower screen is worn, it is necessary to remove the blade for repair or replace it with a new one, and at the same time, clean up the debris and strengthen the filtration of the coating. Heat the coating bucket of the coating machine and turn on the floor paint circulation pump of the coating machine to ensure uniform temperature of the coating and strengthen the filtration of the coating.

The reason for the occurrence of bubbles in the coating film of the light cured paint during the construction of the floor paint for wooden flooring is as follows.

The self defoaming performance of UV cured coatings is poor. The coated wooden board is not coated with putty layer, which prevents the first primer from fully filling the capillary pores of the board. The air in the pores expands and escapes after being heated by the hot topcoat, leveling machine, and curing machine, forming small bubbles in the epoxy floor paint coating and being wrapped in the cured coating, forming bubbles; After larger bubbles break through the coating and escape, pinholes are formed. This type of problem can be solved by the floor paint company using general methods.
