Buying advice

When selecting a silicone adhesive, prioritize the intended environment: use 'kitchen and bath' formulas with mildewcide for wet indoor areas, and high-temperature RTV silicone for automotive repairs. Always check the cure time, as standard silicones require up to 24 hours before water exposure, whereas fast-cure options may be ready in as little as 30 to 60 minutes.
