My method was to lightly go over the clean and dry floor with a sponge with sealer. The sponge was damp, not wet with the sealer. I did this twice and the next morning i grouted. I mixed the grout up fairly still but workable and when i thought it was ready to be cleaned off i went over with a damp...not wet Washboy system. The sealer worked well and it left nice full joints.
