How to Strip and Wax Commercial Floors Step by Step

Stripping and waxing a commercial vinyl composition tile (VCT) floor is the difference between a school hallway that looks tired and one that gleams. Done right, it adds years to floor life. Done wrong, it streaks, traps dirt under the new finish or damages the tile. The technique matters as much as the chemistry.

What You Need

• Low speed (175 RPM) floor machine with black stripping pad
• Wet vacuum or auto scrubber for slurry pickup
• Mop bucket with wringer and a stripping mop
• Stripping chemical (alkaline, diluted per label)
• Neutralising rinse (or just clean water with a small amount of acidic cleaner)
• Floor finish (4 to 5 coats expected)
• Microfibre or rayon finish mop
• Wet floor signs and rope barriers

Step 1: Clear and Sweep

Move all furniture, racks and equipment off the floor. Sweep or vacuum the entire area to remove loose debris. Any grit left under a stripping pad scratches the tile.

Step 2: Apply Stripper

Mix stripper at the labelled dilution. Apply heavy with a mop, leaving a wet film about 1/8 inch deep. Let it dwell for 5 to 10 minutes per the manufacturer instructions. Do not let it dry. If it starts to dry, apply more.

Step 3: Agitate

Run the floor machine with a black stripping pad over the wet area. Move slowly, one section at a time, with overlapping passes. The pad scrubs the wax film loose. The slurry that comes up will be dirty grey or black.

Step 4: Pick Up the Slurry

Use a wet vacuum or auto scrubber to remove the slurry. Do not let it dry on the floor. If you have to wait for the wet vac, mist a little more stripper to keep it wet.

Step 5: Rinse Twice

Rinse the floor with clean water. The rinse pulls residual stripper out of the floor. Skipping this step is the most common cause of finish failure. The new finish will not bond to a floor with stripper residue.

Step 6: Inspect and Spot Strip

Once the floor is dry to the touch, inspect for any patches where the old finish remains. Spot strip those areas with a deck brush and the wet vac.

Step 7: Apply First Coat of Finish

Use a clean microfibre or rayon finish mop. Pour finish into the mop bucket (do not pour directly on the floor). Apply a thin even coat. Avoid puddles. Let dry completely (30 to 45 minutes per coat).

Step 8: Apply Coats 2 Through 4

Each coat goes perpendicular to the previous (cross hatch pattern). Total of 4 to 5 coats for a new install, 3 coats for a re application. Let each coat dry fully before the next.

Step 9: Cure

The floor is walkable in 1 hour but full cure takes 24 to 48 hours. Avoid moving furniture, dragging carts or applying mats during the cure period. The first burnishing happens 48 to 72 hours after the last coat with a high speed burnisher.

Common Mistakes

• Stripper allowed to dry mid job (always re mist)
• Insufficient rinsing (causes finish failure)
• Coats applied too thick (causes streaks and longer dry time)
• Mat applied during cure (sticks to soft finish)
• Old buildup not stripped off the corners

Maintenance Going Forward

A properly stripped and waxed floor lasts 12 to 18 months before re application. Daily dust mopping, weekly auto scrubbing and monthly burnishing extend the life. The first sign that re wax is needed is loss of gloss in the high traffic areas.

Stripping and waxing is the most labour intensive operation in floor care, but it is also the most reset. A school hallway, hospital corridor or retail aisle that has been properly stripped and refinished looks new for the first 6 months and stays good for another year with the right maintenance.
