How do I apply grout renewal?
Subsequently, one may also ask, can you put new grout on top of old grout?
While it's possible to apply new grout over existing grout, the results are usually less than satisfactory. Since the layer of new grout would be very thin and vary in thickness, it may not adhere well and the old grout could show through. Removing grout from a tile floor is not nearly as difficult as it used to be.
Subsequently, one may also ask, how long does Grout Renew take to dry?
Carefully apply to the grout joint and allow to dry 30-60 minutes. Work small areas at a time. Ready for light traffic in 2 to 4 hours, normal traffic in 24 hours. Do not expose to water for 72 hours.
Wash the tiles to remove debris before regrouting. Add 1/4 cup of mild detergent, such as dish soap, to 1 gallon of warm water and mix well. Dip a soft sponge or cloth into the soapy solution and rub it over the tiles.
