A wide temperature range water borne sealant that can be applied at low temperatures. The sealant can be a latex sealant composition including at least one latex polymer, at least one freeze thaw stabilizer, and at least one peptone or at least one additive derived from a peptone. The latex polymer can be an acrylic latex polymer with a Glass Transition Temperature (Tg) of 0C or less. The peptone can be enzymatic hydrolysate. The sealant can remain pliable at low temperatures making it ideal for applications that require flexibility at low temperatures its' rheology and viscosity are such that it can be applied at temperatures below 0C. The low Tg latex assures that the sealant will remain permanently flexible and non-tacky when cured, and the peptone provides the sealant with the means to prevent the water from freezing down to approximately -20C.
