How to Apply

Surface Preparation
Surfaces should be clean, dry and free of all loose material. Wire brushing or sweeping is generally sufficient. Watco Bio-D degreaser can be used to remove grease and oil. If the surface is damp, it can be primed with Watco Tack Coat.

Priming

A primer is not usually required if patch or crack repairing. Watco Tack Coat adhesive primer is recommended when applying Concrex Acid Strength as a thin section screed or when applying to smooth, non-porous or metal surfaces.

Mixing
Each pack of Concrex Acid Strength contains aggregate pre-blended with resin and the curing agent. If the entire pack of Concrex Acid Strength cannot be used within 30-60 minutes, the products can be part mixed. Call our experts at 855-627-6350 for more information on how to part mix.

Tip the aggregate onto a mixing tray or board. Shake the bottles or tins 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 bottles or tins are completely empty.

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. Once mixed, the product is troweled firmly against the surface to be repaired and finished with a steel trowel.

Application
Trowel firmly against the surface to be repaired, and finish with a trowel or float. To prevent 'drag' on the trowel, moisten a rag with white spirit and wipe it across the blade, which will allow you to create a smooth finish. Concrex Acid Strength is normally applied in thicknesses of 1/4", but repairs can be feather-edged for a neat finish, as long as the majority of repair is at least 1/4" thick. For repairs deeper than 1", apply in separate layers (allow 6-8 hours between layers for curing) or use Watco Concrex Deep Fill. There is no need to reapply Watco Tack Coat if building up layers.

Important
Food products must be removed from the area during application and cure.
