Polyurethane Epoxy Floor Coating Roughness Solution

The reason for the rough appearance of polyurethane epoxy floor coating is:

First, the construction environment and floor paint film drying process in the environment is not clean, more dust, so that the dust falls on the paint film is still in the leveling stage, eventually leading to dust on the floor paint coating film and make the film Roughness appears.

Second, epoxy floor paint coating is not filtered before the coating, mixed with mechanical impurities, these mechanical impurities are coated together with the coating on the object to be coated, when the film is dried, the mechanical impurities are highlighted on the floor paint film Finally, it caused the film to appear rough.

Third, because the polyurethane epoxy floor coating is a two-component or multi-component coating, it is also a chemically-cured coating, so when the coating is mixed with a curing agent, the coating starts to play a chemical role, the viscosity of the floor coating coating slowly When it rises, it begins to gel after a certain period of time, and it finally cures to form a film. When the paint begins to gel and continue construction, the floor paint film may appear rough.

Fourth, the construction site temperature is too high, too volatile diluent, Epoxy floor paint coating on the object has not been leveling time has already begun to cure, so there will be a rough phenomenon.

The rough solution:

Do a good job of cleaning the construction site and the dry site, to prevent dust pollution on the epoxy floor paint film. Before the paint is applied, according to the requirements of the product specification, the paint shall be properly prepared (painted according to the proportions of the components, and then adjusted to the viscosity suitable for the application by the thinner). After coating the floor paint, the paint shall be filtered with a 120 mesh gauze before construction. , you can avoid the promotion of rubbing due to mechanical impurities.

Epoxy floor paint before coating, according to the amount of time the coating can be used to calculate the amount of coating, and then the coating ratio and dilution and other follow-up work, how much with the number, can not be more than one. If it is found that there is a gel floor paint can not be used. Use a suitable caliber gun to adjust the air pressure and the appropriate spraying distance. Use a slow-drying, high-boiling diluent.

Deal with the lower layer, starting from the ground floor should be done according to the construction requirements, middle layer should be to prevent rough phenomenon, the surface layer must be cleaned before the construction of the middle, confirmed that no dust and then construction, so that you can solve the epoxy floor paint The rough phenomenon.
