wooden floor before the paint
Posted: Fri Jan 05, 2018 1:31 amIf you clean the floor with a alkaline detergent, and the paint contains acidic components, the two meet, the chemical changes occur, causing paint corrosion, peeling, etc .; Second, some paint varieties poor adhesion, but also easy to cause There are two reasons for poor adhesion:
(1) Some species of wood contain extract components, such as phenolic compounds, that block the polymerization of free-radically-induced UV coatings, resulting in Paint adhesion is not good, resulting in film delamination, severe spalling occurs.
(2) wooden floor before the paint, the floor moisture content is too high (moisture content greater than 12%). As the moisture content is too high, although the surface is painted, when the external environment changes in the wet and dry conditions,
