1. The water that dilutes paint is called thinner, and some of them are directly called thinner. This thinner is a liquid, which can reduce the viscosity of paint after adding paint, so that it will be more convenient and smooth when spraying. Pay attention when joining, not too much, otherwise the paint will become thinner and the brushing the wall will be thinner; It can't be too little, otherwise the wall will form cracks and cause the problem of falling off.

2. Paint thinner is a liquid solvent with good miscibility with resin, which is added to reduce the viscosity of resin and improve its technological performance. There are active diluents and inactive diluents respectively.
