is always a necessary evil. It is extremely important
not to create more dust than necessary. Unfortunately most vacuums
are not designed to collect the fine dust. It simply passes right
through the filter and out the other end. If you own a regular Shop-Vac,
we do not recommend using it for paint dust at all, because you
will disburse the dust in other parts of your home. By running the
vacuum, the air will expand and transport large amounts of dust
into other adjacent spaces. If you are not going to make the investment
in a new HEPA or High Efficiency vacuum, we recommend wetting mop
to keep the dust down to a minimum.
Where you place a vacuum
is also important. If you are using a vacuum
in the same space that you are removing paint, you will most likely
transfer substantial amount of dust into other parts of your house
no matter what vacuum you use. A HEPA or a High Efficiency vacuum
will not pass dust through its filter, but the exhaust from the
motor will create air turbulence and stir dust on the floor into
the air. A simple suggestion is to create a negative air pressure
in the space you are working in.
How to create a negative
air pressure: Cut a plywood sheet to fit a window
in the space you are working. Make a hole to fit the vacuum hose
and the power cord. Install the plywood sheet in the window. Place
the vacuum on the outside of your house. Install the hose and the
power cord through the hole in the plywood and seal with duct tape.
You may have to purchase additional vacuum hose and a power cord.
Using a remote power switch is also a good idea making it easier
to switch the vacuum on and off. Place the vacuum on the outside
with the blower directed away from the window. By having the vacuum
outside, you also do not have to listen to the noise.
Why use an expensive vacuum
when you place it on the outside anyway? Believe
it or not, dust flying around on the outside can still find a way
inside through cracks in windows and doors. By using a HEPA or a
High efficiency vacuum, you will eliminate the chance of having
fine dust getting into your house by capturing it in the first place.
Tape any cracks around doors and windows. Try my suggestion; you
will be amazed how well it works
