In the areas of construction and repairs, polyurethane sealants are known to provide flexibility, strength, and high durability which makes them a top choice. To receive these benefits and ensure longevity, proper application of the sealants is a must. Here are a few suggestions to help you get the best results from your sealant application.

1. Thorough Surface Preparation

For best results while applying sealants, the surfaces must be clean, dry, and free of debris. Dust, old sealant, grease, or any residue needs to be removed to avoid weak adhesion and sealant failure.

2. Choose the Right Weather Conditions

Curing polyurethane sealants requires moisture, thus applying them at extremely hot, cold, or dry temperatures is not advisable. Such conditions only hinder proper curing which consequently weakens the seal.

3. Apply Consistent and Continuous Beads

During polyurethane sealant application, aim for an even, continuous bead without gaps or air pockets. This helps maintain the seal’s integrity and improves waterproofing and flexibility.

4. Tool and Smooth Immediately

Use a proper caulking gun for precise control during polyurethane sealant application. After applying, smooth the bead with a tooling spatula or a gloved finger to enhance adhesion and appearance.

5. Allow Adequate Curing Time

Depending on environmental factors and bead thickness, polyurethane sealants typically cure fully within 24 to 48 hours. Avoid disturbing the sealed joint during this time for best durability.
