Choosing a Treatment
Penetrating concrete sealers are available in water based and solvent based variations. Both formulations penetrate into the concrete and work in the same manner, but it is important to note that when discussing water or solvent, we are discussing the “carrier” of the active ingredients within the sealer. Water-based formulations are the most eco-friendly as they are non-flammable, non-hazardous and is safe to use around food surfaces, people and pets. Water based sealers do not smell and will not add an odor to the food items that it comes into contact with.
Solvent formulas are bit more complex. As a carrier, solvents will carry active ingredients deeper into dense surfaces like concrete. They have higher levels of VOCs (volatile organic compounds) but they perform and last longer than water-based sealers. Although solvent-based products are hazardous in their chemical state, once they are applied and fully cured, they are food-safe. A common misconception is that drying time is the same as curing time. It’s not. Your finish isn’t cured once it’s dried.
