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.
