A glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.

A method of making a reinforcement sheet for a cementitious board includes applying a hydrophilic coating material on binder coated glass fibers, the hydrophilic coating material being mobile in slurry water at a surface of a slurry of a cementitious compound to dilute and disperse, and to wet and spread the slurry on the binder coated glass fibers, and the hydrophilic coating material in the slurry water being volatile to dissipate by evaporation at an elevated temperature at which the cementitious compound is dried for the binder coated glass fibers to be essentially free of the hydrophilic coating material.
