Sealant FAQ Section
What is the difference between silicone and polyurethane sealants?
Silicone sealants offer superior flexibility and UV resistance, making them ideal for outdoor applications and glass sealing. Polyurethane sealants provide excellent adhesion to porous materials like concrete and have better paintability. Our hybrid sealants combine the best properties of both types for versatile applications.
How long does sealant take to fully cure?
Cure time depends on environmental conditions and sealant thickness. Typically, sealants form a skin within 15-30 minutes but require 24-48 hours for full cure. Humidity and temperature affect curing - higher humidity and temperatures accelerate curing while cold, dry conditions slow it down.
Can sealant be painted over?
Some sealants are paintable while others are not. Polyurethane and hybrid sealants generally accept paint well after full curing. Pure silicone sealants typically resist paint adhesion. Always check the product specifications and do a test patch before full application. For best results, clean the surface thoroughly before painting.
