ONR for ceramic grout


Recommended Posts

While having some ceramic tiles installed I noticed the contractor was rinsing out his grout sponge bucket at an alarming frequency(I am paying by the hour, so wasted time is on my dime). Putting 2and 2 together I dropped an oz of ONR in his bucket, the grout residue in the bucket dropped out of suspension and he did not rinse out his bucket for the rest of teh job. I have a new customer for ONR!
