Why is maintaining a 'wet edge' important when brushing or rolling large walls?
a.It prevents lap marks by blending each new stroke into paint that is still wet
b.It makes the paint dry faster
c.It increases VOC content
d.It is only needed when spraying
解析
Working to a wet edge means each new area of paint merges with an area still wet, so the overlaps blend invisibly. If the edge dries first, the overlap shows as a darker lap mark. Planning the sequence and working quickly across manageable sections maintains the wet edge.
