1. Adjacent Substrates
- Uncured sealant must not come into contact with surfaces adjacent to the sealant joint. If uncured sealants are introduced to prohibited areas, the sealants should be removed as follows:
- Non- Porous Substrates: Immediately remove all excess uncured sealant by using xylene, toluene, methyl-ethel ketone, or isopropyl alcohol. Ensure all cleaning agents are compatible with installed substrates or other building facade materials.
- Porous Substrates: Allow sealant to develop initial cure, then remove by abrasion or other mechanical means. Exercise extreme caution in order to maintain an undamaged original sealant surface texture. Compatible solvents, cleaners, and poultices may be utilized to remove any remaining residue.
2. Tools and Equipment
- Tools and equipment may be cleaned with solvents such as xylene, toluene, methyl-ethel ketone, or isopropyl alcohol while sealant is uncured.
Note: Maintaining clean application tools and work areas will result in higher quality sealant applications.
