CM/Spotlight: Hard Floor Care A floor sealer and a floor finish are not the same product. A sealer will have a higher solids percent-age — after evaporation, more polymers remain on the floor — than a finish, effec-tively filling pores and smoothing out incon-sistencies in resilient tiles. Sealers are used for building a base before you apply a finish and, given their high solids percentage, they exhibit little or no shine — a sealed, unfinished floor will have a dull or matte appearance. Even though some tiles come with a factory-applied sealer, you must seal a floor before applying finish. A high solids percentage in a floor finish does not make it a sealer; it does, however, mean it will be very difficult to remove when it comes time to strip. 2. The Second Myth Of Floor Care: A floor should be sealed after it has been stripped and refinished Despite that it is an old idea and an out-dated practice, I still see this mentioned in articles by floor care professionals. Floors do not need to be sealed after strip-ping; resilient flooring needs to be sealed when it is first laid down. Two to three coats of sealer should be applied, turning 90 degrees with each new coat — if you are going north-to-south when applying the first coat, apply the next in an east-to-west manner — then end with a final coat. If done correctly and at the proper time, the floor will never need to be sealed again. To prove this once you have stripped a floor bare, use a red pad and buff the bare floor; a matte shine will appear, this is the sealer still in the floor. If your floors are poorly stripped — there is often little time to complete floor care tasks and a small amount of old finish can remain — and then sealed, you will seal in the old, dirty finish, which makes the floor yellow faster and makes future restorative main-tenance harder and more time-consuming. 3. The Third Myth Of Floor Care: A floor stripper can be applied and quickly mopped away This myth actually contradicts the core cleaning principle of time, agitation, chemical and temperature (TACT). First, the idea implies that you do not need dwell time and that you can just apply a product and then mop it off. Second, it infers you don’t need to agitate the surface with a floor machine and a scrubbing/stripping pad. If the stripper is so strong that you can mop it on and then easily mop it off, you either have very little finish left on your floor or your rubber boots will melt while you apply the solution. All strippers need dwell time — surface contact upwards of 20 minutes in most cases — and you need to use a swing machine with an abrasive pad to effectively remove the floor finish. I am sorry, but there are no shortcuts here, and a mop-on, mop-off floor stripper is about as real as a unicorn. 4. The Fourth Myth Of Floor Care: If a surface is considered no-wax floor-ing, it doesn’t need to be finished Marmoleum, a type of linoleum flooring made of recycled materials, bonding agents, linseed oil and wood particulates, was and still is promoted as no-wax flooring. The truth is that there is no such thing as a no-wax floor. All resilient flooring needs a finish, as it protects the floor from damage. Without finish, floors will wear and discolor more quickly and can be permanently dam-aged. While resilient flooring of all kinds has a protective surface coating, it is a manufac-turer’s coating applied at the factory and is only designed to prevent damage to tiles before they are installed. When initially installed, resilient floors require a light scrub, the application of a sealer and at least three coats of finish. 5. The Fifth Myth Of Floor Care: Restorer can save you time and money Remember back in the day when you or your coworkers would mix a 50/50 solution of finish and stripper in a spray bottle to spray buff the floor using a swing machine operat-ing at 350 revolutions per minute (RPM)? Before high-speed floor machines or ultra-high-speed (UHS) finishes, spray buffing was a common task. Today, restoration finishes are essentially a waste of time and money. Think about it: For the time it takes to mix your solution, apply the restorer and complete the spray buffing task, you might as well just refinish the floor with a top scrub and recoat. 6. The Sixth Myth Of Floor Care: Top scrubbing and stripping are one in the same A common assumption made by custodi-ans is that, because they used stripper when they scrubbed the floor, it is stripped. In reality, however, the floor has not been stripped. To strip a floor properly — to remove all of the finish down to the substrate — you need to leave the stripper on the floor for at least 20 minutes, agitating with a mop or other tool so it does not dry. Then, after allowing the stripper to dwell, scrub it using a brown or black pad before picking up the slurry with a wet vacuum. Now, the floor is ready to be rinsed and neutralized, which should be done a mini-mum of three times — more if all of the finish is not removed. Simply using stripper and giving the floor a quick scrub and rinse is not consid-ered stripping; said process is more akin to heavy-duty scrubbing or what is commonly called a top scrub.
