How to Apply add

Surface Preparation: Surfaces should be clean, dry and free of all loose material. Wire brushing or sweeping is generally sufficient. If needed, wash with Bio-D® or a suitable degreaser or detergent solution, to remove grease and oil. Rinse and allow to dry.

Priming: Tack Coat adhesive primer is recommended when applying Concrex® as a thin section screed or when applying to smooth, non-porous or metal surfaces.

Mixing: Concrex® should be stored at an ambient temperature above 50°F for approximately 8 hours prior to use. Do not use material if air and surface temperatures are below 50°F. Each pack of Concrex contains aggregate pre-blended with resin and the curing agent. Do not mix inside the plastic bucket. Wearing protective gloves, tip the aggregate on to a mixing tray or board. Shake the containers of curing agent thoroughly until the liquid is a uniform color. Form the aggregate into a mound and leave a small hole in the middle. Empty the curing agent into the hole, ensuring the container is completely drained. Carefully mix the aggregate with the curing agent using a trowel until a smooth mortar is obtained. This will take several minutes. The more thorough the mixing, the ‘wetter’, smoother and more manageable the mix becomes. Alternatively, you can knead the mixture by hand, but you must wear suitable gloves. It is important to mix thoroughly until you achieve a consistent color.
