Abstract
Seal a fenestration opening that contains a gap having a width of greater than 1.6 millimeters by providing a dispersion having the following components dispersed in an aqueous phase: (i) a film-forming polymer binder having a glass transition temperature in a range of −100 degrees Celsius to −20 degrees Celsius; (ii) a shear thinning rheology modifier at a concentration sufficient to cause the dispersion to have a Brookfield viscosity greater than 300,000 centiPoise as measured using spindle #3 at 0.3 revolutions per minute; and (iii) optionally, a filler; and then spraying the dispersion directly onto the building elements within the fenestration opening so as to form a continuous coating over the building elements and gap within the fenestration opening; wherein there is an absence of reinforcement or sealing material filling or spanning the gap prior to spraying the dispersion over the gap.
