Pressure washing your external sidings before painting
them allows you to remove grease grime, pollutants, and caulking adhering to your exterior walls. If you use the proper cleaning solution you can also remove spores and
mold. You can paint your exterior without cleaning the sidings first; the paint will apply well,
adhere well, and look good, but the job won't last as long as paint applied after the sidings are cleaned.
While cleaning the exterior of your house by hand is superior to pressure
washing, you need to be realistic. Cleaning your home's exterior by hand is a
long painstaking process. On the other hand,
pressure washing does an adequate job and will provide
a clean base for your paint job. If the PSI is set high enough, power washing
can also be used to clean off old layers of paint; however, keep in mind that the pressure
needed to remove paint, might damage your home's exterior.
Pressure washing is accomplished in four steps. In step 1, the
pressure washer blows away external grime such as dust, spider webs, leaves,
and other adherent dirt. In the next stage, a cleaning solution is sprayed onto
the siding from the bottom up, using a plastic sprayer. Combinations of cleaner
and bleach are effective in killing mold and mildew. The solution should be
allowed to sit on the siding for at least 10 minutes, but not long enough to
dry. This is followed by wash down with the pressure washer. After rinsing, the
siding should be allowed to dry for 48 hours, but no longer than 2 weeks.
During this interval the paint can be scraped away, if needed. You are now
ready to paint the exterior. If there is a delay of more than 2 weeks after the
rinsing, it should be repeated and allowed to dry before applying the paint.
If you don't have the time or equipment to do thepressure washing yourself, contact an exterior painting and or
local landscaping company to do the job for you.
