More features

• Easy to Use: Each 30g bag is individually wrapped for freshness and convenience, helping to reduce waste. No special tools or mixing required! Simply knead the soft, pliable putty with your fingers until it’s ready to mold, making any repair job simple and mess-free.
• Versatile & Protective Sealant: This all-in-one sealant is designed for countless tasks. Use it to fill wall holes, cracks, and gaps around pipes and cables, or as a plumber’s putty for sinks and a duct sealant for HVAC. It also forms a robust barrier, while its heat-resistant and flame-retardant properties make it a practical choice for electrical boxes and utility penetrations.
• Durable & Long-Lasting: Once applied, our sealant cures to form a firm, airtight, and waterproof seal that stands the test of time. It resists cracking, shrinking, and drying out over time, ensuring your repairs remain secure and effective against air and moisture for the long haul.
• Performs in All Conditions: Whether in hot, cold, damp, or dry environments, this sealant holds strong without losing adhesion. A versatile solution for year-round home maintenance, both indoors and out.
• Trusted Professional Finish: The putty gradually hardens upon exposure to air, giving you ample time to achieve a smooth, custom finish. This slow-curing process helps ensure a neat and professional-looking result for every repair, big or small.
