Open Joint For Low to High Movement Greater than one Inch
wood construction with plywood/OSB sheathing
Apply a 3/8-inch bead of SureSpan Adhesive on both sides of the joint. The 3/8-inch bead will spread to a width of 1/2 inch (minimum 20 mils thick). Sealant coverage may vary depending on the porosity or texture of substrate.
After location of SureSpan EX placement is set, place the SureSpan EX into the wet sealant using hand pressure to adequately spread the SureSpan Adhesive onto the extrusion. Small adjustments to the placement of the SureSpan EX may be done at this time, but lifting and re-seating should be avoided and may result in needing extrusion into the wet sealant.
Use a small roller such as a laminate roller to apply sufficient pressure to set the SureSpan Adhesive. Gun an additional 1/4-inch bead of SureSpan Adhesive to capture and counterflash the exposed edge of the extrusion. Tool excessive sealant immediately.
