The Process of Stripping and Waxing Commercial Floors

 

Regardless of the type of business, commercial floors can quickly accumulate dust, grime, scratches, cracks, and other damage due to foot traffic. Neglected floors can be off-putting. Therefore, a scheduling stripping and waxing regularly can help protect the flooring and improve its appearance.


Stripping the floor involves removing layers of old floor wax and sealants before applying a new wax coating. The new protective wax creates a barrier between the floor surface and shoes and furniture scuffing, moisture, and other damage. Floor types that benefit from this process include acrylic, linoleum, epoxy, and vinyl composition tiles (VCT) floors.


Standard stripping-and-waxing treatment requires a stripping tool and solution, floor wax, mop, buckets and wringer, floor pads, auto scrubber, and a low-speed floor buffer. Experts recommend a 20-inch buffereasyse of use, handling, and manageable weight. A "Wet Floor" caution sign may be required for busy locations such as offices.


The first step is to dust-mop the floor before removing the old wax and sealant layers. Mix the stripping solution in a bucket per the instructions. Fill a second bucket or auto scrubber with cold water, and install the floor pads. For the best results, sectionalize the floor, depending on the stripping tool used. Next, apply the stripping solution to the floor section, and wait five to 10 minutes for it to dissolve the old wax and sealant. Move to the next section and repeat the process till the whole floor is covered.


Strip the area with the floor pads attached to the pad driver of the auto scrubber for several passes until the section is cleared. Move to the next section and repeat. Corners and crevices require an edging tool. Lastly, mop the spent stripping solution and wet-clean using cold water.


The stripping procedure takes longer than waxing, though the total time usually depends on the layers of wax applied previously. After stripping, seal using a sealing solution that permeates the flooring's pores, scratches, and shallow cracks and prepare the surface for waxing and finishing. Cleaning experts recommend applying two coats of sealant to cover the imperfections.


After the sealing solution dries, apply the wax. Professionals recommend three to five coats of high-quality wax for the best results. Mix the wax per the label instructions and put it on the floor using a clean applier mop. Allow it to dry before subsequent layers are added.


The final stage is finishing and buffing. Apply a finishing solution to help the wax settle on the floor. This reduces the chances of scratches and dirt buildup and promotes a smooth finish. Once the solution dries, buff the floor to remove dust and bring out a lustered finish. Buff when the gloss dulls during the period before the next stripping and waxing.


The stripping and waxing frequency depends on the level of wear from human traffic, objects, and weather elements. For regular foot traffic, you should strip and wax the floor annually. Consider stripping and waxing every six months for heavy traffic in places like learning institutions, shopping malls, and public transit facilities.

Choosing the Right Pressure Washer for Algae Removal


 

Algae grow on hot, humid surfaces, and a swimming pool area provides the environment for algae to thrive. The slimy green microorganism is unsightly and can be an injury hazard. While some DIY methods, such as hot water and vinegar, work for minor algae infestation, extensive and stubborn algae growth requires thorough and effective elimination techniques, like using a pressure washer. Fed by water through a garden hose, pressure washers use a vacuum or pump to send the water out through a high-pressure nozzle.


Consider the water pressure and flow when selecting the pressure washer for algae. The two crucial metrics of power washers are gallons per minute (GPM) and pounds per square inch (PSI). GPM determines the surface area covered by the water flow and rinsing power, while PSI indicates the water pressure. The two account for the pressure washer’s cleaning unit (CU) performance.


Dirt comes off easily under 50 PSI, but this does not work for algae removal, especially when lodged in cracks. Surface algae stains require about 1,000 PSI to remove, while stubborn growth calls for between 1,400 and 3,000 PSI. A residential pressure washer typically provides a maximum of 3,000 PSI, while a commercial version peaks at about 4,000. Do note that pressures over 3,000 PSI, typically used to remove rust, will strip a pool deck’s paint or dislodge sealants.


Selecting the pressure washer for algae by the GPM is trickier, but hinges on the area and the cleaning speed. A residential pressure machine with a flow rate of 2 gallons per minute requires more time for the same area of algae growth than a commercial version, which ranges between 6 and 9 gallons per minute. Experts suggest choosing the power washer based on GPM over PSI, as too much pressure can make the machine harder to handle and cause damage.


Considering the proximity to the pool water, the cleaning solution type and delivery mode both matter. While the pressurized water dislodges algae by itself, and does so better than a standard garden hose or broom, an additive such as commercial algae cleaning solution does ease the cleaning process and reduces the chances of recurring growth.


As for the type of machine, experts recommend a downstream injector pressure washer instead of the built-in soap tank type. The former first pressurizes the water, picks the soap, cleaning detergent, or bleach using a vacuum effect, then delivers the mixture to the nozzle. The built-in soap tank mixes the water and detergent first, then passes the solution through a pump and then to the nozzle. This working principle can result in pump damage from household cleaning solutions, even mild soap. Most washers have a “no bleach” caution on their bodywork.


The spray water nozzle on a pressure washer determines suitability for different applications. The types, identified using a nozzle number consisting of four or five digits, guide the user on the application. The first two digits indicate the nozzle spray angle in degrees. The four standard nozzle measures are 0, 15, 25, and 40 degrees. Experts recommend the 25-degree type for removing algae growth from the pool deck.
