Paint is now mainly divided into oil-based paint and water-based paint, and the biggest difference between them is that water-based paint is more environmentally friendly than oil-based paint. Will the adhesion of water-based paint be worse than that of oil-based paint? What are the reasons for affecting the adhesion of water-based paint? What can be done about it?

There are several reasons that affect the adhesion of water-based paint:

① The substrate is not thoroughly cleaned, and dust and oil remain on the workpiece or have not been properly polished

② The construction substrate is not suitable, and the selection of primer is not suitable for water-based topcoat

③ Not completely dry after spraying

The solutions to improve the adhesion of water-based paint are as follows:

① Dust and remove oil from the substrate before making the primer. For the workpiece with a smooth surface, it is necessary to thoroughly polish the surface to coarser and then carry out subsequent construction.

② When using water-based paint, choose a primer that is suitable for water-based paint, rather than spraying water-based top paint with an oil-based primer

(3) Water-based paint as a self-drying water-based paint, its adhesion will reflect different effects with the drying degree of the film itself, the better the drying, the stronger the adhesion, after spraying to be completely dry before the next step in the construction operation, the appropriate can be heated or hot air drying.

The adhesion of water-based paint is not strong enough, find the reason and then correct it. Of course, before the purchase of the correct understanding of the process and choose the right water-based paint in order to better avoid some subsequent trouble.
