Spalled joints should be repaired initially using Watco Concrex. For best results use Watco Back Up Rod to reduce deeper joints to the desired depth. Apply primer by brush to the sides of the joint and allow to dry (approx 30 minutes at 20ºC). Mixing It is important that the two components are very thoroughly mixed together. Poorly mixed product will not cure correctly. Empty the contents of the smaller tin into the larger tin and mix thoroughly for approximately 3 minutes using a wide bladed tool such as a palette knife. Alternatively use a slow speed electric drill and paddle. Immediately decant the mixed components into an empty container, ideally a jug (plastic or metal) or can with a pouring spout. This will assist when pouring the product into the floor joint.
