Abstract
Buildings and walls are commonly constructed with exterior walls composed of fiber exterior panels, such as fiber cement panels or glass reinforced gypsum exterior sheeting. The spaces between the exterior panels are sealed using the system and method of the present invention. The space is first filled with an acrylic flexible joint compound. A thermally set, spunbonded, reinforced, polyester non-woven joint tape is then applied. The tape is then covered with a ceramic mud. After curing of the ceramic mud an acrylic elastomeric coating is sprayed, brushed or rolled on the fiber cement panels. A cement-free stucco coating or a variety of other coatings may then be applied over the exterior panels.

A method for sealing the spaces between panels on exterior walls comprising the steps of:
- filling the joint with an acrylic based flexible joint compound;
- taping over said acrylic based flexible joint compound with a reinforced spunbonded joint tape;
- applying a layer of a ceramic mud over said tape;
- covering the entire panel with an acrylic elastometric coating;
A method for repair of imperfections in exterior wall panels comprising steps of:
- filling the imperfection with an acrylic based flexible joint compound;
- smoothing the filled imperfection with a ceramic mud;
- applying layering an acrylic elastometric coating over said ceramic mud;
A method for sealing the spaces between exterior panels used in the construction of exterior walls comprising the steps of:
- filling the space with acrylic flexible joint compound,
- covering the said acrylic flexible joint compound with thermally set, spunbonded polyester nonwoven reinforced joint tape;
- and
- applying an acrylic elastomeric coating.
A building comprising:
- a plurality of exterior panels affixed to the building, said exterior panels having spaces there between wherein:
- the spaces between said exterior panels are filled with an
- acrylic flexible joint compound over which is layered a thermally set,
- spunbonded polyester nonwoven reinforced joint tape which optionally may be covered with ceramic mud to which an acrylic elastomeric coating is added.
A system for filling and sealing the spaces between fiber cement panels attached to a building frame comprising a dual acrylic rubber-like gasket sandwich with or without a ceramic core.
