Application Guide

1. Surface Preparation: Ensure all surfaces are structurally sound, stable, dry, clean, and free of dust, loose material, oils, grease, form release agents, curing compounds, and any other contaminants. Ensure surfaces are free from surface water and continual dampness. Concrete must be allowed to cure for at least 28 days.
2. Priming: Due to the high bond strength of Adheseal sealants, adhesion is very often achieved without priming on most substrates. For optimal adhesion and critical high-performance applications, follow priming or surface preparation guidelines as per Adheseal recommendations.
3. Application: Cut the nozzle at a 45º angle to the desired thickness. Insert the sausage into the sausage gun. Hold the gun at a 45º angle with the nozzle in contact with both sides of the joint. Apply by pushing sealant ahead of the nozzle, ensuring sealant is pushed firmly into place in a steady continuous bead, ensuring good contact with both sides of the joint.
4. Tooling: Tool off with a moistened spatula to finish the joint smoothly before the skin forms, approximately 5 minutes.
5. Cleaning: While the product is still wet, clean tools and spills with Xylene. For cured product removal, use mechanical means. For cleaning skin, use Adheseal Hand Wipes.
