Question

I mixed floor finish from two different suppliers. The finish did not flow well when applied, and the floors are now dull and streaky. Can I spray buff the floor to bring out the shine? And how does a person spray buff? Or would just buffing do the job?


Answer

Answer #1:
Iíve encountered this problem and found I had to mop on restorer, burnish (1500 rpm), dust mop, damp mop and lay one additional coat of finish. Burnishing alone did not eliminate the streaks.

Answer #2:
Both the difficulty with the finish leveling well when applied and the resulting streaks indicate a compatibility problem. The two finishes had different chemical make-ups and did not mix well. Try the foregoing suggestions to see if there is an improvement.
If not, your immediate best solution may lie in stripping off the mixed finishes and recoating with only one brand.
Spray buffing (light spraying of the tile with a prepared solution and immediately buffing it dry with a red pad) may or may not help. Manufacturers formulate spray buff solutions specifically for their finishes, and what you wish to spray buff is a hybrid finish. In addition, spray buffing may not penetrate deeply enough into the layers of finish to eliminate the streaks.
Another approach is to allow the finish to wear until a heavy scrub and recoat is called for and then do it using a single finish.
