Brush and Roller Basics – Sherwin-Williams


[music playing] It’s amazing how the right
tools and a few tips can make any paint job easier,
faster and more successful. Many jobs, especially
new construction, will include a combination
of spray application and brush and roll application. Regardless of the type of job, there are a few best
practices to follow. Whether you’re
spraying or rolling inside or out, it’s a good rule of thumb
to start at the top and work your way down. For interior jobs, that means painting
the ceiling first, then using a brush
to cut in at corners and around any trim, like woodwork, baseboards,
crown molding and so on. For these areas, we recommend using
a 2.5-3 inch angled brush to paint about a 2-inch
band onto the wall. If you’re painting
a larger area, however, a straight edge 3-inch brush
will get the job done faster. Regardless of the job, the paint you’re applying
will determine the brush to use. A high quality brush made
with synthetic bristles of nylon or polyester is the best choice
for latex paints, while natural china
bristle brushes deliver better flow and leveling for oil-based paints,
stains and varnishes. Holding any brush
for hours is tiring, but this technique
will reduce fatigue and result in a smoother,
streak-free finish. Hold the brush near
the base of the handle and dip it halfway
up the bristles. Tap the excess off
on the side of the can. Wiping it on the side of the can
can create drips. Press the bristles
against the surface lightly. Too much pressure can cause runs
and a sore wrist. When painting trim,
use the same technique. However a smaller size brush
may provide more control. On new construction, if the trim has not been
pre finished off site, paint trim after the base
coat has been sprayed, but before paint is rolled. As you’re painting, cut in one wall at a time
with your brush, then roll paint onto
the rest of the wall while the cut in band
is still wet. It’ll result in a more
seamless finish when the paint dries. Although roller covers are
a common choice for covering large areas, not all roller covers
are created equal. Just like choosing
the best brush for the job, the surface you’re painting and the type of paint
you’re using will also determine
the right roller cover. If the surface is smooth, you’ll want a roller cover
with a shorter pile or nap height. Heavily textured surfaces,
like stucco or some ceilings, will require a roller cover
with deeper pile. to ensure good coverage
on uneven surfaces. Different types
of roller cover fabrics are also designed
to optimize results. Synthetic covers are
ideal for latex paints. Natural fiber covers,
like mohair or sheepskin, are designed for
oil-based paints. Otherwise the water
in latex paint can cause natural fibers
to swell and get matted and blended covers combine
the pickup power of natural fibers
with polyester for longer life. These hybrid covers can be used
with any type of paint. For better performance
when using a new roller cover wrap a strip of inverted
masking tape around your hand and run it across the surface
to remove loose fibers. Otherwise those fibers
may come off on the wall and ruin your hard work. When you’re ready,
pour some paint in a roller tray and move the roller back
and forth a few times until it’s evenly coated. Then draw it across
the ridges of the tray to remove excess paint. Working in 2-foot sections,
make an N pattern and cross roll
to spread the paint. Finish each section with
light roller strokes at right angles to
the cross rolling. Maintain light pressure
for even coverage across the entire surface to provide a smooth,
attractive finish that also satisfies the coating’s recommended
film thickness. Mil thickness is a measurement of the thickness
of the paint film when it’s applied to the wall. It’s important because
paint is formulated to perform best
at a specified thickness. Apply too much paint
and the coating may sag. Too little coating will
result in poor hide or insufficient defense
against moisture or UV damage. The coating manufacturer may express the required
thickness as wet mil thickness or dry film thickness, which simply refers
to the thickness before or after the paint is dried. Although there are
several types of gauges used to measure mil thickness,
this common tool has notches spaced at
1 millimeter increments. Hold the gauge at a 90 degree angle
to the surface and press firmly, ensuring that both sides
contact the substrate. The number above
the last visible notch indicates the mil thickness
of the coating. If you’re measuring
wet film thickness, there will be a trace
of paint on the gauge. Make sure to clean the gauge
as soon as you’re finished so it’ll be accurate
the next time you take a reading. Whether you’re
painting inside or out, temperature matters. Many new home interiors
can be chilly, so having a heat source will ensure that the paint dries
to the desired color and finish. Outside, you should paint
when the humidity is low and the temperature is between
70 and 85 degrees Fahrenheit. When the humidity is high, water based paints will
take longer to dry. On sunny days, try to follow the shade so wet paint isn’t exposed
to direct sunlight. That can cause
the paint to blister. And just like interior painting,
it’s best to start at the top and work your way down, always maintaining
a wet edge as you work. If you paint into an area
where the paint is already dried, the film could buckle
or peel later, The last step is clean up. High quality brushes
will last for years if properly maintained. For latex paints,
warm water and a mild detergent are all that’s needed to clean a
synthetic bristle brush. Rinse your tools in fresh water until there’s no sign
of residual paint. For oil-based paints, clean up using
the recommended solvents. Always follow manufacturer’s
safety recommendations when using solvents. And of course, never
pour unused paint down a drain or storm sewer. Consult your local
recycling agency for more information on
proper disposal regulations. Follow these suggestions and you’ll have
a great paint job that’s efficient, great-looking
and delivers lasting performance.
