We’ve tracked down a more efficient caulking compound — one that does not contain toxic VOCs (volatile organic compounds) such as toluene and hexane. These are present in conventional caulk because they are cheap to produce. One company, AFMSafeCoat, produces a caulking compound that is a water-resistant, flexible sealant with excellent adhesion.
This caulk will not dry out or crack, and it does not release any solvents. It can be used in sinks, showers, around pipes, and between walls and woodwork. It’s available from the Environmental Home Center for $6.50 per tube.
