SUPERIOR STUCCO STAR GLUE is intended to be field mixed with Type I-II Portland Cement meeting or exceeding ASTM C150. SUPERIOR STUCCO STAR GLUE can be used to adhere EPS board or shapes (with reinforcing mesh) as well as used as a base coat over EPS board and as a Leveling Coat over approved substrates.


SUPERIOR STUCCO STAR GLUE should be mixed thoroughly with a Heavy Duty Drill & Mix paddle (not to exceed 500 RPM) Pour half of mixed SUPERIOR STUCCO STAR GLUE into a second clean bucket and add equal parts of Type I-II Portland Cement (1:1 mix ratio) and mix for approximately 3-5 minutes. Allow SUPERIOR STUCCO STAR GLUE to take its’ initial set after mixing (few mins). Re-temper/mix to a smooth creamy consistency; clean potable water may be added for workability. DO NOT OVERMIX.


Apply SUPERIOR STUCCO STAR GLUE to back of EPS Insulation Board with notched trowel. Press Insulation Board onto approved substrate. Allow SUPERIOR STUCCO STAR GLUE to set for a minimum of 24 hours prior to working on the EPS Insulation Board. SUPERIOR STUCCO STAR GLUE as a Base Coat over EPS Insulation Board should be applied a minimum of 1/16” (3.2mm) thick to completely embed Reinforcing Mesh into wet base coat. Be sure to trowel smooth, with no mesh showing. SUPERIOR STUCCO STAR GLUE as a Leveling Agent can be applied to the area needed to be leveled after following mixing directions. Additional clean potable water may need to be added to create the proper mixture. Application method will vary due to job conditions. Protect from inclement weather until cured.
