Power
Washing - Pressure Washing Tips
Below is a
picture of me and my power washers

1. When pressure washing, think of the surface as six
o'clock. Now, pull the trigger at four o'clock, slowly ease the
spray to the six o'clock position (approximately 12 inches away
from the surface, but certainly varies) make a nice long even
pass (no back and forth stuff) and then ease the spray up to
the 8 o'clock position before releasing the trigger. Power
washer marks are like tattoos in your wood deck or masonry
surface. Always start in the most un-noticeable part of the job
and allow yourself to get familiar with the process, it will
make a big difference in the appearance of your work where it
counts the most. You will also have much less time in
the job not having to fix ugly, aggressive power washer marks,
if it's even possible.
2. If you are
pressure washing a wood deck, make sure to wash one or
two boards at a time, depending on the distance that seems to
be working well. Do not have the top or bottom part of the fan
pattern cutting into the adjacent board. Do not go back and
forth. Think long and even passes. Never pull the trigger if
the wand is aimed at the surface, this will keep unwanted power
washing marks from appearing. A couple of easy even
passes are always much better that trying to speed up the
process by being too aggressive.
3. If you are
washing a concrete or masonry type of surface, always
do step #1 and as you are making your passes make sure to
overlap by 50 %. For professional results, if you washed the
concrete in a East to West direction, now wash it again in a
North to South direction. This is almost always necessary in
helping eliminate power washer marks especially when removing
heavier or stubborn debris from the surface.
4. Several pressure
washer manufacturers make an osculating tip. This tip takes a
zero degree fan pattern and spins it in a circular motion.
These tips can make a job go much faster in many circumstances,
but are very aggressive. Always start in an
inconspicuous place.
5. If you have power washing
that requires a ladder, do know that General Pump manufactures
high- quality extension poles. The DLTG 18A collapsed length is
7'5" and extends to 18 foot. The DLTG 24A collapsed is 9'5" and
extends to 24 foot. These are the best poles that I have found
for power washing. Most poles are simply junk. If something
breaks on the General Pump poles you can get the part to
replace instead of disposing the whole unit. This tool will
undoubtedly save the homeowner or professional contractor
considerable time and money in many circumstances. To find
