- Apply SeamSeal on all metal seams, joints, fasteners and penetrations at 75 to 100
linear feet of seams per gallon or 450 fasteners per gallon.
- Coat all surfaces including expansion joint covers and flashings. Extra material is
required at all edges and penetrations if neoprene sheet flashing is not used.
NOTE: Application rate is job-specific. Additional material may be required due to surface profile,
losses due to overspray and wind, and residual coating left in the container.
