I'm looking for some guidance on whether using a limestone densifier is appropriate for an issue I'm having.
The customer had a honed limestone floor installed inside their home. The installer applied a topical sealer, to provide semi-gloss finish. After a couple of years, the sealer began to fail, so the customer contacted me to strip, hone, polish, and seal (solvent impregnator). The floor looked great, but after a few months the traffic areas began to show signs of excessive soiling.
If I had used a densifier, could this have possibly prevented the soiling issues? If I were to apply the densifier now, would it be necessary to strip the floor first, to remove the impregnating sealer that I applied 6 months ago?
