What is "Stripping" Floor Finish?

Stripping floor finish is a comprehensive process involving the deliberate removal or “stripping” of the existing floor coatings or finishes from the flooring substrate material. This method is typically employed when the current floor finish has worn out, become discolored, or needs replacement. The stripping process is thorough and involves the use of specific chemicals, machinery, and cleaning procedures to achieve optimal results. Here are additional details to provide a more in-depth understanding of the floor stripping process

Purpose of Stripping

Old Finish Removal

The primary purpose of stripping is to eliminate the old or worn-out layers of floor finish. This is essential when the existing finish has lost its luster, developed scratches, or is no longer providing the desired level of protection.

Surface Preparation

Stripping prepares the flooring substrate for the application of a new layer of floor finish. It creates a clean and bare surface, ensuring better adhesion and longevity for the subsequent finish.

Components of Stripping

Stripping Chemicals

Harsh stripping chemicals are utilized in the process to break down and dissolve the existing floor finish. These chemicals often contain solvents, surfactants, and other active ingredients designed to effectively lift and emulsify the old finish.

Buffing Machines

Low-speed buffing machines equipped with coarse black pads are employed during the stripping process. These machines mechanically agitate the stripping solution, assisting in the removal of the existing finish.

Safety Equipment

Due to the use of potentially hazardous stripping chemicals, proper personal protective equipment (PPE) such as gloves, goggles, and, in some cases, respirators may be required to ensure the safety of those performing the stripping.

Stripping Procedure

Area Preparation

The area to be stripped is cleared of furniture and obstacles. Floor mats or protective coverings may be placed around the perimeter to contain the stripping solution.

Application of Stripping Chemicals

The stripping solution is evenly applied to the floor surface, ensuring thorough coverage. The chemicals are allowed to dwell for a specified time to break down the old finish.

Mechanical Agitation

Low-speed buffing machines, equipped with coarse black pads, are used to mechanically agitate the stripping solution. This action helps to loosen and lift the existing finish from the floor.

Removal of Stripped Solution

The dissolved finish, along with the stripping solution, is then removed from the floor surface. Wet vacuuming or auto-scrubbing machines with appropriate recovery systems are commonly used for this purpose.

Rinsing with Fresh Water

After the majority of the stripped solution is removed, the floor is thoroughly rinsed with fresh water to neutralize any remaining chemical residue. This step is crucial to prevent interference with the adhesion of the new floor finish.

Post-Stripping Considerations

Drying Time

Adequate drying time is allowed for the flooring substrate to ensure complete evaporation of moisture before applying the new floor finish.

Compatibility Testing

Before applying a new finish, compatibility testing may be performed to ensure that the substrate is ready and suitable for the selected floor finish.

Safety and Environmental Concerns

Proper Ventilation

Stripping is often performed in well-ventilated areas to mitigate the inhalation of fumes from stripping chemicals. Adequate ventilation is crucial for the safety of individuals involved in the process.

Waste Disposal

Disposal of the stripped solution, which may contain remnants of the old finish and stripping chemicals, must comply with local regulations and environmental guidelines.

Conclusion

Understanding the intricacies of the floor stripping process, including the purpose, components, procedure, and safety considerations, is vital for facility managers and cleaning professionals. Properly executed stripping ensures a clean slate for the application of new floor finishes, contributing to the overall appearance and longevity of the flooring in commercial and institutional spaces.
