What is an adequate time frame after grouting to apply a sealer?
Some sealer companies recommend 3-7 days. C-Cure recommends allowing the grout to cure 28 days or more prior to sealing. Sealing a grout too soon can effect the hardness of the grout and often create an unwanted/uncorrectable color change due to trapping of moisture beneath the sealer. If you seal the grout too soon, you accept all responsibility for the grout on the job. If sealing the grout cannot be postponed, the customer should be certain they are happy with the grout color and conditions. An inconspicuous area should be tested prior to sealing the entire job.
