Superior Features of Dowsil 781
Excellent Adhesion
Dowsil 781 offers outstanding adhesion to a wide range of non-porous surfaces commonly found in hot tub environments. It bonds exceptionally well to glass, aluminum, painted surfaces, and composite boards.
Durability
Engineered to withstand the challenging hot tub environment, Dowsil 781 resists aging, shrinkage, cracking, and discoloring. This ensures long-lasting seals that maintain their integrity over time.
Versatile Application
This sealant is suitable for various hot tub applications, including:
- Sealing joints between tub and surround
- Waterproofing around jets and fittings
- Bonding decorative elements
- Creating watertight seals around windows or transparent panels
Brilliant White Finish
The crisp white color of Dowsil 781 blends seamlessly with white or light-colored surfaces in hot tub areas, creating a clean, professional look.
How It Works
As an acetoxy sealant, Dowsil 781 cures by reacting with moisture in the air, forming a durable, elastic silicone rubber. This process allows it to maintain flexibility while providing a watertight seal, accommodating the natural expansion and contraction of materials in changing temperatures.
Application Tips for Professional Results
- Surface Preparation: Ensure all surfaces are clean, dry, and free from grease before application.
- Precision Application: Use masking tape for crisp, clean lines, especially important with the white color.
- Continuous Bead: Apply the sealant in an unbroken bead to ensure full contact with both surfaces.
- Timely Smoothing: Smooth the sealant within 5 minutes of application using a wet spatula or finger for a professional finish.
- Proper Curing: Allow 24-48 hours for full cure before exposing to water, depending on environmental conditions.
