Their purpose goes beyond simply “filling gaps”. Sealants protect joints and surfaces from moisture, dust, vibration, and even extreme temperatures. The right product not only improves the structural integrity of your work but also contributes to long-term durability, reduced maintenance, and improved energy efficiency. To help you navigate the variety of options, here's a breakdown of common sealants, their ideal applications, and why quality matters.

Types of sealants and where to use them

Sealants come in many forms, each tailored to specific tasks and environments. Here’s how to choose wisely:

• Silicone sealants: These are the go-to choice for wet environments such as bathrooms, kitchens, and around windows. They’re flexible, waterproof, and resistant to mould and mildew. It is ideal for areas prone to constant moisture exposure. Silicone is also perfect for sealing glass-to-glass or glass-to-metal joints, offering a long-lasting, crystal-clear finish.

• Polyurethane sealants: Known for their incredible adhesion and durability, polyurethane sealants excel in heavy-duty construction and outdoor applications. They are weather-resistant, paintable, and remain flexible under stress, making them suitable for expansion joints, masonry, concrete, and exterior cladding.

• Acrylic sealants: Ideal for indoor use, especially where painting over the joint is needed. Acrylics are easy to apply, dry quickly, and are perfect for baseboards, drywall cracks, and trim where minimal movement is expected. However, they're not recommended for wet or highly flexible environments.
