Eliminates the need to roughen the surface prior to application. Exceeds performance requirements of ASTM C 1059 Type I and II. If cold temperatures threaten to wreak havoc on your concrete repair, consider SikaLaTex Concrete Bond Adhesive. Brush it, spray it, or spray it onto the existing concrete surface, or use it as a substitute for water in a concrete slurry or mortar.

Alternatively, use it in a grout mix, a particularly attractive option for tile floors in unheated mud. As seen above, concrete will not adhere to another concrete material if an effective concrete adhesive is not applied. However, if there are unresolved problems with old concrete, including frost and cracks, they can be moved to new concrete. A bonding agent (bonding adhesive) must first be painted over the existing concrete to ensure that the fresh concrete adheres properly.

If it is a deck or slab repair, mixing concrete with a bonding agent allows you to work quickly and form the repair on the platform. When patching existing concrete, here's how to achieve a strong and durable bond between new and old concrete. Products such as Sakrete Sand Mix and Sakrete Fast Set Cement Patcher will work well with a liquid chemical binding agent such as Sakrete Bonder %26 Fortifier. When using a liquid adhesive agent, paint the adhesive onto existing concrete and allow it to dry until it is tacky.

Even though it is possible to bond an old concrete to a new one, you should do it in the best way to prevent gaps or cracks from occurring. Start by carefully sweeping away all loose stones and dirt and rinsing the concrete to prepare the surface. The thinnest layer of new concrete you should apply to old concrete is about 2 to 2 ½ inches. In order for concrete materials to bond effectively to each other, you must apply an adhesive bonding agent.

Liquid Nails LN-905 landscape block adhesive creates a weatherproof bond that resists the effects of water, resulting in a long-lasting concrete wall, garden bed or masonry project You must wait for the right weather conditions, select the right cement mix, use the proper proportion and work quickly enough that the concrete does not begin to set before it is ready. To avoid completing the same project twice, be sure to follow the instructions on the concrete agent packaging. As in the process described above, after the adhesive has become tacky, apply a scrape coat and then apply the repair material. In the above cases, you must remove the old concrete and resolve the underlying problem, such as leveling the concrete before continuing to lay new concrete.
