Clean and Dry the Surface Before Sealant
Remove oil, dust, moisture, loose coating, and metal chips so the approved sealant bonds to the actual surface.
Stop if
- This metal is [oily/wet/coated]. What surface prep and cleaner does the approved sealant require before I apply it?
Watch out
- Do not smear mastic over condensation, dust, cutting oil, or loose coating and expect thickness to make up for poor adhesion.
Check
- Check temperature and moisture conditions
- Wipe factory oil and dirt with an approved method
- Remove loose rust or coating without damaging the substrate
- Dry the joint fully
- Apply within the product's allowed conditions
