- Preparation & Application
Surface Preparation: Joint sides should be clean and dry. Spalled joint sides should be repaired with Concrex®. Back Up Rod can be used to reduce deeper joints to the desired depth. Apply primer by brush to the sides of the joint and allow to dry. (Approximately 30 minutes at 70°F).
Mixing: It is important to thoroughly mix both components together. Poorly mixed product will not cure correctly. Empty the smaller container into the larger container and mix thoroughly for about 3 minutes with a power mixer. Alternatively use a slow speed electric drill and paddle. Immediately pour the mixed components into an empty container (plastic or metal) or a can with a spout, which will also help to pour the mix accurately into the floor joint. Take care to ensure that all the contents are scraped off the sides and bottom of the containers. Mix again for one minute. If a pouring can is not available, crimp the rim of the empty container to help with pouring. Use within 1 hour.
Application: Joint Width/Depth: For joints 1/4-3/8" wide, depth should be equal to the width. For joints 3/8-3/4" wide, depth should be 3/8". For joints over 3/4" wide, depth should be half of the width. Crimp the rim of the container being used to facilitate pouring and pour evenly into the prepared joint, leaving the top of the sealant joint just below the surface of the floor. If required, finish off with a flat blade or knife to remove air bubbles and then remove any masking tape before the sealant has set, drawing the tape across the sealant face so that any excess sealant falls into the joint and not alongside it. Floor Joint Sealant will adhere to clean concrete, epoxy and other types of floor coatings, and most other common floor materials. It will also adhere to steel and other non porous materials.
