23. Techniques of
painting

24. Air spray:
Air spraying is fantastic for industrial paint
jobs. An air sprayer uses air to atomise the
paint into a mist or fine spray.
24

25. Airless spray:
 An airless sprayer atomises the paint at a
much higher pressure than an air sprayer.
It’s great for spraying large industrial areas
quickly and more efficiently than an air
sprayer

26. BY Roller:
 If you plan on painting a flat surface such
as a floor or wall, a roller can come in
handy. Using a roller to apply paint allows
you transfer paint efficiently and quickly

27. Paint brushing:
 Paintbrushes come in such a wide variety of styles,
shapes, angles and even bristles, that there’s one for
every task. Small paint brushes are excellent for smaller
details
