Methods for treating paperboard or paper media are provided. In these methods, a composition is applied to the surface of the paperboard or paper media. Paperboards or paper media treated in accordance with any of the methods achieved increased strength under both dry and wet testing methodologies as compared with untreated paperboards and paper media of the same basis weight.

A method for increasing moisture retention in a soil includes applying an effective amount of an effective humectant composition to the soil. The effective humectant composition is identified by determining the average moisture content of the soil for the humectant compositions applied at a minimum humectant concentration level, a maximum humectant concentration level, and at a first concentration level between the minimum and the maximum humectant concentration level. An average slope curve is generated by plotting the determined average moisture content of the soil for each applied humectant concentration levels from the minimum humectant concentration level to the maximum humectant concentration level. An effective humectant composition is determined when the generated average slope curve provides an increasing average moisture content along the entirety of a length of the generated average slope curve and when the generated average slope curve has a p value of 0.05 or less.

A gypsum board comprises a cover sheet and a gypsum layer disposed on the cover sheet. The gypsum layer comprises the reaction product of an isocyanate, water, and stucco. The isocyanate increases the moisture resistance of the gypsum board. A method of manufacturing the gypsum board comprises the steps of combining the isocyanate, the water, and the stucco to form a slurry, and applying the slurry to a cover sheet to form the gypsum layer on the cover sheet.
