Abstract: The present invention provides a device for applying a fluid sealant with a light touch, the device comprising a wand with a fluid sealant supply, either as part of the wand or as a separate supply tube, attached to the top of an applicator head via a universal joint, wherein the applicator head has a chamber on its underside which is sufficiently large to enable a constant supply of a fluid sealant to a substrate that is to be sealed, and the applicator head has a chamber edge disposed around its lower periphery adapted to strike the sealant flat. In addition, the present invention provides methods of using the devices to form a seal, e.g. a weather-resistive barrier on a sheathed building structure, by applying a flexible and compressible foam to gaps in the structure. The foam may comprise one or more aqueous polymer having a glass transition temperature of less than 25° C.

Abstract: The present invention provides aqueous self-inspecting wet coatings or films that dry to form translucent to clear weather-resistive barriers on a substrate, preferably a building substrate such as sheathing. The coatings comprise, as a wet film, one or more aqueous emulsion or dispersion polymer that can form a film in use conditions and less than 6% pigment volume concentration (% PVC), of one or more opacifier, one or more extender in amounts up to critical % pigment volume concentration (CPVC), optionally, one or more pigment, and substantially no void, hollow core, or hollow sphere containing pigment. The coatings or films enable one to apply the correct amount of coating to make a weather barrier that dries to a see-through coating or film.
