Floor Finish Characteristics - The primary purpose of a floor finish is to
protect the floor. The secondary purpose is to enhance its
beauty, and the third purpose is to help to make daily
maintenance easier by providing a smooth coating that can be
easily swept, dust mopped, cleaned or repaired.
Following is a list of characteristics that all floor
finishes can be rated on.
The type of finish chosen will depend on the needs
of your floor surface in relation to these characteristics:
• Removability - When a finish is put down on a floor
surface, you want to be able to remove it as it becomes soiled
or discolored. An
ideal floor finish is designed with a certain amount of
removability in it. It
should be able to withstand multiple scrubbing and traffic,
and then you should be able to remove it with a compatible
stripper.
• Soil Resistance -
The finish's ability to resist the damaging effects of soil on
the surface of the film.
Floors can appear dirty on the surface if the finish is
not able to keep the dirt from imbedding within the finish's
film.
• Slip Resistance - Slip resistance is a
measurement of the coefficient of friction.
The ideal floor finish slip resistance would not be
less than 0.5 (measured on a James Machine) and no greater
than 0.6, unless it is an unusual situation where a higher
slip resistance is desired.
If the slip resistance is less than 0.5, there will be
a tendency to slip on the floor.
If the slip resistance is higher than 0.6 or 0.8, there
will be a tendency to catch your foot and alter the working
pattern, (i.e., you stumble or stub your toe on the floor).
• Durability - When you put a floor finish on the floor, you
want it to be able to withstand the abuse and not show wear
patterns. Ideally,
the finish should not be stripped off more than once a year.
• Drying Time - When you apply the floor finish to the
floor, you want it to dry relatively fast, usually within
thirty minutes. Some
floor finishes are designed to
dry in a shorter period of time so that multiple coats can be
put down in less time.
• Coverage
– Most floor finishes are designed to give approximately
2500 square feet per gallon, which will reduce your cost and maximize the value of the product.
• Gloss
– When a floor finish is applied, you want the depth
achieved by applying multiple coats.
The wet-look or gloss shine can easily be achieved with
the finishes of today.
•
Leveling – When a finish is applied, it should
sheet out and leave no marks on the floor.
•
Non-Foaming – You want a finish that is
non-foaming. If
this characteristic is missing, the action of moving the mop
in the bucket and through the wringer, will create foam,
which can leave bubbles in the floor finish that pop once the
finish dries, creating rings in the finish.
•
Buffable and Non-Buffable – There will be
times when you want a product that is buffable, so that you
can repair scuffs and scratch marks.
There are other locations, such as patient rooms or
classrooms, where you want a non-buffable finish that is cost
effective, dries bright and is hard.
Hon-buffable finishes are more resistant to scuffs and scratch marks, but more time consuming to maintain.
•
Freeze-Thaw Stability – Your floor finishes
should be designed to pass three freeze-thaw cycles, be
certain you stir the liquid so that it will flow freely with
no grain or separation during application.
•
Recoatability – When you are applying multiple
coats of finish, expect it to be dry and recoatable within
thirty minutes. You
want to be able to lay down another coat of finish without
excessive “drag.” When you recoat, the topcoat should interface with the
preceding coat so that they merge together and form one
continuous film.
•
Water Sensitivity – Most coatings have some
sensitivity to water standing on their surface. The sensitivity shows up as a softening or whiting and dulling of the finish. A
quality finish will show greater resistance to the effect of
standing water for greater periods of time.
•
Detergent Resistance – A finish should exhibit
good detergent resistance, otherwise it will be scrubbed away
each time the floor is cleaned.
Poor detergent resistance can also show up, as dulling
after the floor has been damp mopped.
•
Powdering – Powdering is usually caused by
poor stripping procedures or application of finish onto a cold
floor. Floor
finish can also powder when subjected to the heat and friction of high speed burnishing. Be sure to only use high speed rated finished if you are
utilizing a high-speed floor care program.
