One of the biggest challenges for
floor maintenance technicians is identifying the floor coverings they will be
working on. In the modern world of flooring, ceramic and porcelain can be
manufactured to resemble stone flooring, laminates take on the appearance of
wood, and resilient flooring may resemble wood, stone, diamond plate and
numerous other products. Is it any wonder that the technicians are getting
confused?
The resilient category of flooring
consists of linoleum, cork, rubber, non-vinyl polymeric poured seamless floors
and vinyl products. Innovations over the years have led to the development of
an interesting classification of flooring often referred to as luxury vinyl
tile. Truth be known, there is no such classification as luxury vinyl tile; it
is just an easy name to describe solid vinyl, class III, printed film products,
as well as other products that are not solid vinyl at all.
Vinyl floor coverings are products
that contain polyvinyl chloride (PVC). Most floor maintenance technicians can
tell you that the vinyl classifications consist of two styles – sheet flooring
or tile flooring – but they may not know what constitutes the difference.
The American Society for Testing
and Materials designates two specifications and standards for sheet vinyl
flooring: ASTM F 1303 sheet vinyl floor covering with backing and ASTM F 1913
sheet vinyl floor covering without a backing, and two specifications and
standards for vinyl tile: ASTM F 1066 - Vinyl Composition Tile (VCT) and ASTM F
1700 – Solid Vinyl Tile (SVT). The basic difference between them is the amount
of PVC used in the product.
VCT has significantly less PVC and
more filler than SVT, which makes it less flexible and more porous. It is also the
reason you will never see VCT in sheets; there is not enough PVC in the product
to make it flexible enough to roll up. It will just break. Therefore, VCT is
easily identified by its 12-by-12-inch tiles.
SVT contains PVC and other
ingredients that constitute 34 percent or more of the tile by weight. SVT is
manufactured in tile and planks of varying dimensions. There are three classes
of SVT: monolithic SVT has color throughout the body of the tile and no
backing; surface-decorated SVT is a tile where the pattern or design is either
printed on the surface or has colored chips inlaid and layered onto the backing
with a wear layer on the surface; and printed film, in which the pattern or
design is printed on a film and layered between the backing and a clear
heavy-duty wear layer. All of these products may have a smooth surface or an
embossed surface.
Solid vinyl class III printed film
tiles or planks are very popular and are found in many different environments.
The construction consists of a backing, the printed design, a clear film
protective layer and a heavy duty wear layer and many may also have textured
surfaces. Because of the heavy-duty wear layer of the SVT printed film
products, there is the perception that these floors are invincible. Granted they
are indeed durable, but everything succumbs to the effects of erosion, no
exceptions. Most manufacturers recommend using minimal cleaning solution and do
not recommend using anything more abrasive than a medium scrubbing brush or
pad. Stripping and some heavy scrubbing brushes or pads are too abrasive and
may cause damage to the surface. Most manufacturers of these products are open
to the use of floor finish programs if desired, but adhesion can be difficult
on some of these surfaces. Always follow the manufacturer’s recommended
maintenance methods for best results.
Initial maintenance for these
floors consists of dry soil removal and a thorough mopping. Generally this will
suffice, but in some situations a light or medium scrub may be necessary to
dislodge more aggressive soils. Most manufacturers recommend limited use of
cleaning solution for the first few days to allow the flooring adhesive to
cure; never drench or over saturate the floor. Once the floor is clean,
applications of floor finish may be applied if desired.
Maintenance should include matting
programs that position walk-off mats at each entrance and be of sufficient
length to capture soil as it enters the building. Daily/routine maintenance is
the removal of soils by dust mopping, cloth systems or vacuuming followed by
damp or wet mopping. Sometimes a buffing program may help to keep a better
appearance.
Periodic maintenance will usually
consist of a light or medium scrub with neutral or all-purpose cleaner,
depending on if the floor system incorporates floor finish. This may be
accomplished using a spray-buff method in which the technician will mist an
area with cleaning solution and machine scrub it with a low-speed rotary floor
machine affixed with a light-to-medium scrubbing brush or pad. The area will
then be rinsed and damp mopped to remove excess water. Buffing the floor with a
soft pad afterwards when floor finish is not used may be necessary.
Of course, the technician may also
perform the light to medium scrub in the traditional sense when floor finish is
used, as long as he minimizes the cleaning solution. Lightly apply cleaning
solution to a manageable area and scrub with a low-speed rotary floor machine
with light to medium scrubbing pads or brushes. Rinse the floor thoroughly,
allow it to dry and reapply floor finish.
Restorative maintenance is
required when floor finish systems are used, and consists of the stripping and
refinishing service procedure. The difference here is the controlled use of
cleaning solution and abrasive pads or brushes. Mix the stripping solution only
as strong as needed to remove the finish; in some situations all-purpose
cleaner at a lower dilution ratio will suffice. Machine-strip the old finish
off with a slow speed rotary floor machine with medium scrubbing pads only; do
not use stripping pads or brushes. Detail edges, corners and baseboards and
rinse the floor thoroughly with fresh water. Once the floor has dried, reapply
floor finish to the desired gloss level.
Solid
vinyl printed film flooring need not be something to be afraid of. It is
actually not that difficult to maintain. The technician just needs to remember
that these floors are constructed a little different than other floors and
require more attention when working on them. Limit the cleaning solutions and
the abrasiveness of the pad or brush, and everything should work out just fine.
