About this item

Product details

This Waterproof Sealant Mastic is a hand-kneadable sealing clay designed for quick gap and hole mending, featuring excellent waterproof and airtight performance to block water seepage, cold wind and pest entry. The soft duct seal putty can be arbitrarily shaped to match irregular wall holes, air conditioning pipe openings and drain connection joints, requiring no professional tools for convenient DIY repair. Once settled, it stays solid and crack-resistant under varying indoor and outdoor temperatures, effectively sealing pipeline gaps, wall cracks and cable through-holes. A practical all-purpose mending mud for home wall renovation, air conditioner installation, plumbing connection repair and multiple indoor & outdoor sealing needs.
