2382 CSR Poultice is formulated specifically for the removal of deep-seated copper stains from masonry surfaces. It is to be mixed with 2381 CSR II and in most cases with 2383 CSR Poultice Additive. 2382 is safe for use on most unpolished surfaces. 2382 CSR Poultice is suitable for use on exterior surfaces only.

2382 CSR Poultice is mixed to a paste like consistency that will hang on a vertical surface. Standard plasterers tools and mixing devices are customary for the preparation of the product and application to the surface. Protect all surfaces that are not to receive an application of 2382 CSR Poultice. Apply a test sample to the project surface to determine the suitability of the cleaner, acceptable application method, thickness and required dwell time to effect the desired cleaning.

Using a broad knife, trowel or other application method, apply a uniform layer of 2382 CSR Poultice to a thickness of 3/8 to 1/2 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 high-pressure spray, wet sponges, toweling or soft brushes. All poultice residues must be removed to avoid a film appearing on the surface. Allow the surface to dry and repeat the application where necessary.

2382 CSR Poultice is for use by professional contractors only. Keep out of the reach of children. Application to surfaces that are below 50 degrees F may not react as expected. Usage at temperatures below 70 degrees F may require extended dwell times. Do not use when temperatures are expected to drop below 40 degrees F during the projected dwell time.
