Solvent-based grout sealers contain more of these compounds which are bad for the environment as well as human health. VOC stands for volatile organic compounds. The upside of using water-based grout sealers is that they are generally lower in VOCs. However, with the scientific development of various formulations, most water-based sealers penetrate deep enough as grout tends to be very porous as it is.
