Q. Is it safe to sand off heavy buildup from a VCT floor?
A. Sanding a VCT floor would normally void any warranty. There are some powerful strippers on the market that should remove the finish while using a nylon grit brush, or a black or dark brown strip pad. Your local Jan/san supplier should have the several products available that can do the job. Applying the stripper at maximum strength (per manufacturer’s instructions) and allowing adequate dwell time is critical to success.
We do not sand VCT or VAT flooring, although we may abrade some semi-permanent seals or polyurethane coatings prior to recoating. Sanding would void any warranty on flooring and may damage the surface and create a health and disposal hazard. Should sanding be done on VCT as a last resort salvage procedure, a 100 grit mesh screen disk under a strip pad will accomplish the task, however the surface must be kept wet to avoid damage and airborne contamination. Test a small area (six inches square) by hand prior to widespread use to avoid any surprises and liability for damage. You may also want to involve the customer in the decision making process to avoid problems once the work is complete. Check out our new Floor Care Training Manual.
