The Novagard Silicone Adhesive Sealant provides excellent adhesion to a wide range of materials, including:
-
PVC and ABS plastic
-
Fiberglass
-
Ceramic and tile
-
Glass
-
Stainless steel
-
Concrete and masonry
Once cured, it forms a flexible, permanent bond that remains strong and waterproof in wet or submerged environments.
100% Silicone – No Shrinkage or Cracking
Unlike latex or hybrid caulks, Novagard’s 100% silicone formula retains its elasticity and shape even after years of use. It won’t shrink, peel, or lose adhesion when exposed to:
-
Continuous water immersion
-
Chlorine or saltwater
-
High UV and ozone exposure
-
Temperature swings between -40°F and 400°F
This flexibility ensures long-lasting performance in both indoor and outdoor conditions—ideal for pools, spas, fountains, and water features.
Waterproof, Flexible, and Chemical-Resistant
The Novagard Silicone Sealant forms a completely waterproof seal once cured. It’s specifically engineered to resist degradation caused by:
-
Pool chemicals (chlorine, bromine, and ozone)
-
Saltwater systems
-
High humidity environments
-
Sunlight and weather exposure
Whether you’re sealing return fittings, tile joints, pump lids, or spa jets, this sealant creates a durable, watertight bond that stays flexible under stress.
Easy Application and Fast Curing
Novagard Silicone is designed for ease of use. It flows smoothly from standard caulking guns and self-levels slightly for clean, even application.
Directions for use:
-
Clean the surface to remove dirt, oil, and old sealant.
-
Apply a continuous bead to the bonding area using steady pressure.
-
Tool the sealant immediately to smooth and shape before skin forms.
-
Allow to cure for 24 hours before exposure to water (longer for thick applications).
The sealant is tack-free in about 10–15 minutes, forming a strong bond as it cures fully. Once set, it remains flexible and watertight for years.
Applications for Pool and Spa Maintenance
The Novagard Silicone Adhesive Sealant is one of the most versatile sealants in the pool industry. Common uses include:
-
Sealing skimmers and main drain gaskets
-
Waterproofing pool light niches
-
Securing tiles and coping joints
-
Repairing cracks in spa shells or fittings
-
Bonding PVC plumbing and return fittings
-
Gluing small accessories or faceplates
It’s safe for use on both fresh and saltwater systems, and once cured, it won’t affect water chemistry or clarity.
Resistant to Harsh Pool Environments
Pools and spas expose sealants to some of the harshest conditions imaginable—heat, UV, water pressure, and chemicals. The Novagard Silicone Sealant outperforms conventional adhesives with superior weathering resistance and chemical stability, maintaining elasticity long after installation.
This means no more brittle seals, failed joints, or recurring leaks—just reliable performance you can count on season after season.
Professional Results for DIY or Service Technicians
Whether you’re a pool contractor, maintenance professional, or DIY homeowner, this silicone makes sealing and bonding simple. It offers professional-grade performance with user-friendly application and cleanup, helping you achieve a neat, durable finish every time.
