Grout fills seams between tiles. Most grout you will be using is porous. It means will absorb any liquid and dirt, It will becomes dirty, stain, mold, and reservoir of bacteria. Overtime, it affects the cement and causes tiles to crack or pop up; which will cost thousands to re-tile! Our service is perfect for giving your home a fresh new look by renewing your grouting( tile line). Or protecting your newly renovated floor. Or just anywhere that you have grout; it can even be used outside or around pools!
