HOW CAN I KEEP MILDEW FROM
GROWING ON MY NEW EXTERIOR PAINT JOB? WHAT SHOULD I
DO WHEN PLANNING THE PAINT JOB?
Mildew is a black or brown fungus that can grow on,
and disfigure surfaces, including paint. While you may
not be sure of getting a 100% mildew-free paint job,
especially over a long period of time, there are some
precautions that can help significantly in reducing
or avoiding mildew growth on a paint job. Try to take
as many of these into account as you can, when planning
your paint job.
WHAT IS THE BEST METHOD FOR
REMOVING A PIGMENTED STAIN FROM REDWOOD SIDING. WE ARE
TRYING TO RESTORE THE REDWOOD TO IT'S NATURAL STATE
SO WE CAN PRESERVE IT WITH A CLEAR PRESERVATIVE?
There is no easy way to do this, as you might imagine.
Consider these possibilities:
1. Chemical remover. Paint remover can be effective
but tedious. Apply stripper in a heavy coat by natural
bristle brush; protect skin, breathing and eyes with
chemical resistant gloves, goggles, overalls, and
an appropriate respirator. Do small areas at a time,
at 10 square feet max. Allow to stay on for 20-30
minutes (time may vary due to weather conditions),
then remove the softened stain with a 3" spackling
blade, onto a disposable drop cloth. Protect plants,
and keep children and pets away. Then move to another
area. You'll probably have to sand the wood after
it dries, to get the last of it off, and to get the
color you want.
2. Sanding. Sand the wood with the grain, using #100
- #120 grit production or aluminum oxide paper. A
3" or 4" belt sander will work well for
bevel siding if have the strength to hold the sander.
Use care to sand the wood evenly and not dig into
it. Wear goggles, gloves and a quality dusk mask.
Power washing and sandblasting are other possibilities,
but with redwood, these would have to be done by a
pro who is very experienced with doing the procedure
Be aware that you will probably have to reapply the
clear material every year or two to maintain appearance.
I HAVE SEVERAL CONTRACTORS
QUOTING ON PAINTING THE EXTERIOR OF MY HOME. HOWEVER,
WHEN QUESTIONED ON WHAT IS THE BEST METHOD TO APPLY
THE PAINT (HAND BRUSH OR SPRAYER), THEY ARE AS MANY
OPINIONS AS THERE ARE CONTRACTORS. THE EXTERIOR SIDING
Basically, both spraying and brushing are fine, so
long as the paint is put on at the proper spread rate
(sq. ft./gallon). Spraying will provide a smoother
appearance, and the painter has to be careful about
getting a full coat onto areas that are next to areas
that won't be painted, so careful masking must be
done. Some people think sprayed paint will not adhere
as well as if brushed, but we have not seen that,
so long as the surface has been properly prepared.
