FAQ's about Airless sprayers:
1) Question - Can an airless sprayer be used
to spray a car?
Answer - No, airless
sprayers air unsuitable for automotive applications, the flow of
material or paint is too high and the finish would not be satisfactory.
Automotive spray painting is best done using an air compressor and air
spray gun.
2) Question - Can an airless sprayer be
used as a water blaster or high pressure cleaner for cleaning driveways
etc?
Answer - The average
airless sprayer would be unsuitable for use as a high pressure water
blaster because the average machine would not have enough water flow to
be an effective cleaner. Using an airless sprayer as a water blaster
would lead to premature wear of the seals and components.
3) Question - Do I need to thin the paint
to spray with an airless sprayer?
Answer - Generally no,
thinning would only be required if you wanted to change the finish of
the spray, some painters may thin the paint to produce a 'stipple" type
of effect in the spray finish but thinning the paint in general terms
will simply reduce the coverage of the paint on the surface.
4) Question - How much faster is applying
paint with an airless spraying against brush and rolling?
Answer - In general
terms, applying paint with an airless sprayer is considered
approximately "four times faster". This is not to say that you will not
need to brush and roller, applying coatings with an airless sprayer is
usually used at the beginning of a project, to apply the undercoat and
base coats, finishing some areas with a brush and roller will still be
required.
5) Question - How long will an airless
sprayer tip last before it is worn?
Answer - The life of an
airless sprayer tip will vary between coatings, but an airless sprayer
tip is considered to last for between 500-1000 litres of paint before
being worn to the point that it should be replaced.
