Paint Removal
In order to
achieve the brand new finish that so many homeowners
strive for, it is often required that you remove a coat of
paint or varnish. There are several ways to do this. The
most common approach involves using a chemical paint or
varnish removal. Paint can also be sanded away, removed by
heat, power washed, or metal brushed.
Chemical Paint Removers
In most cases, chemical paint removers are the easiest and
quickest means for removing old paint or varnish. Chemical
paint removes, also referred to as paint strippers, will
soften painted surfaces, allowing one to scrap off or wash
away old paint. Once applied, it is a good idea to test
the paint by rubbing the blade of a chemical-resistant
scraper on the treated surface to see if it has been
loosened. Scraper options include putty knives, a wooden
blade, old rags or an abrasive scouring pad, depending on
the texture of the surface.
Chemical removers are available in semi-paste and liquid
forms. Basic types include liquids, brush-on, spray-on,
and aerosols. Newer removers consist of chemicals that are
more "environmentally friendly." However, these removers
are more expensive and they typically work much slower.
Other specialty removers are made for specific coatings
including stained fiberglass.
The use of chemical removers requires a certain amount of
protection. Make sure to remove all furniture and other
personal belongings, and cover floors and steps. Always
wear chemical-resistant gloves, eye protection, cover all
areas of skin and work in a well-ventilated area.
Generally, areas that have been chemically treated and
scraped should then be sanded. Paint or varnish can be
sanded away with any type of power or hand sander. Keep in
mind, fine sand paper clogs up quickly and should be
avoided as a means for paint removal. Also, for extreme
rough textures such as brick, stucco and masonry, a wire
hand brush can be used to remove paint and varnish.
Additional Methods Of Removing Paint
On certain exterior surfaces that require total paint
removal, electric heat plates and heat guns have been
proven to work successfully. The heat gun is heavier and
more tiring to use than the heat plate. It is, for the
most part, extremely effective for removing paint from
detailed work because the nozzle can be directed at
rounded and obscure surfaces. It saves time and energy if
both tools are used in conjunction with each other. It is
extremely important to take safety measures against eye
damage and possible fires when attempting to use an
electric plate or heat gun.
In addition, power washing is an option for paint removal,
but it can be a tricky thing. It has been proven to
effectively lift old pealing paint, but if not properly
used you can cause more damage than good. High pressure
power washing can cause the water to penetrate exterior
sheathing and damage interior finishes. This is why it is
important to keep it at least 8” away from the surface and
point the nozzle in a horizontal or downward angle. |
