Joint Preparation
Expansion joints must be backed with a firm, consolidated joint filler board, such as Hydrocell, prior to laying the joint bandage system. (If necessary, joints may have to be pre-sealed prior to laying the joint bandage system. Refer to technical data sheet for further information). All joints must be prepared in accordance with the manufacturer’s current technical data sheet.

Surface Preparation
The joint surfaces must be thoroughly dry, clean and free from frost. Remove all laitance, curing compounds, form release agents, loose materials and any contaminating foreign matter from bonding joint faces by grinding, grit blasting or wire brushing. All dry residual dust from joint cutting operations should be completely removed using a rotary power brush or dry abrasive blasting. The prepared sealing slot should be blown out with dry, oil-free compressed air.
New concrete must be allowed to cure for a minimum of 28 days before joint bandage installation.
