Dilution and Coverage

Coverage: Approximately 2 to 3 square feet per pound depending upon application thickness.


Using a broad knife, trowel or other application method, apply a uniform layer of SB 2320 to a thickness of ¼ to ½ inch of product. Application method should ensure that there are no voids that will cause stains to remain in the surface. Before the poultice dries, cover the surface with a lightweight plastic sheet. Avoid air pockets when applying the plastic sheet. Air pockets may allow the poultice to dry prematurely. Allow the poultice to remain on the surface for 12 to 48 hours as determined by previous testing. If the poultice is very damp after removal of the plastic sheeting, allow the poultice to dry for several hours prior to removal. Remove the poultice with plastic or wood scrappers, taking care to avoid marring the surface. Remove as much poultice as possible and rinse with wet sponges, toweling or soft brushes. All poultice residue must be removed to avoid a white film appearing on the surface. Allow the surface to dry and repeat the application where necessary.
