Buying Guide

Match formulation to application

Choose 100% RTV silicone for long-term waterproof seals and mildew resistance, or high-viscosity formulas for bonding plastics and vertical surfaces

Consider cure type and odor

Acetoxy-cure silicones can have stronger odor and may corrode some metals; neutral-cure or low-odor options reduce fumes and yellowing risk

Check viscosity and set time

Higher-viscosity adhesives (better for gaps and vertical joints) differ from low-viscosity sealants that flow into tight seams; pick based on gap size and working time

Prioritize weather and waterproofing performance

If exposed to outdoor conditions or constant moisture, pick products labeled weather-resistant, waterproof, and no-yellowing for lasting clarity and adhesion

Assess packaging and quantity for projects

Bulk multi-packs or larger-ounce cartridges lower per-unit cost for repetitive tasks; single smaller tubes suit one-off repairs
