More and more people are adopting a DIY lifestyle, choosing to
tackle projects around their house themselves over hiring a professional. And
while most home renovations and upgrades can be done yourself, there are a lot
of DIY misconceptions floating around. We set you straight below with seven
common DIY misconceptions and the truth behind them.
For the most part, paint
strippers do the same kind of job: they
strip paint off of surfaces. However, not every paint stripper is
the same, and not using the appropriate stripper could cause permanent damage
to the surface you’re working with. There are actually three categories of
paint stripper: biochemical, caustic, and solvent. Biochemical-based strippers
are derived from plants, but still contain some chemicals and can irritate
skin. Caustic strippers are water-based with lye as the active ingredient,
which could be either sodium hydroxide or potassium hydroxide. This stripper
causes a reaction that loosens the paint from its surface. Health risks include
skin burns and lung irritation. Solvent strippers instead dissolve or soften
paint from its surface, causing it to bubble up. Solvents are often methylene chloride,
with alcohol, acetone, or ketones present.
The words cement and concrete are often used interchangeably.
Although cement and concrete are related, there is actually a difference
between the two. To start, cement is an ingredient in concrete.
Cement itself is a fine grey powder which kind of looks like flour. Concrete,
which has a mixture of paste (water) and aggregates such as sand, gravel, or
crushed stone, needs cement because of its unique adhesive properties that make
it a great binding agent.
A lot of people assume that if
the nail or screw is long it will be stronger and hold things better than a shorter screw.
However, longer nails or screws can actually cause damage to wiring or plumbing
in the walls. That’s why it’s better to use the right length.
Not only does the length of the screw matter,
but so does the type. Back in the day, people only had the option to use a
slotted or Phillips screw. Now, there are so many more options because we have
the choice to use drills instead of only screwdrivers. Power drills need screws
that won't slip or completely strip the metal off.
Although it may seem that a 2x4 would be 2 inches by 4 inches,
that’s not the case. A 2x4 board does start out as a
true 2x4 in measurement when it's first rough sawn from the log. However,
through the drying process, the board eventually turns to 1 ½” x 3 ½” for
softwoods like pine, spruce, and fir, and 1 ¾” x 3 ¾” for hardwoods like oak, maple, and cherry.
There are a lot of tutorials
and articles online that suggest using bleach to clean mold, but, believe it or
not, you can’t kill mold with bleach. If mold is growing on a porous surface,
such as wood or Sheetrock, it makes it even harder to clean, and bleach won’t
be able to penetrate it properly. Bleach is a water-based substance with
chlorine mixed in. But the chlorine evaporates fast, leaving you with moisture
that could make the mold worse. And definitely don’t mix bleach with other cleaners,
which could create a toxic gas.
When deciding to tackle a DIY project yourself, you might not
realize you need a permit for certain things. Even though it's your home and
you have the right to renovate it yourself, some projects do require a permit.
For example, most cities will require permits for projects like installing new
electrical wiring, converting your garage, and demolishing a load-bearing wall.
Make sure to check with your city as to whether or not you’ll need a permit for
your next DIY project.
