Construction Method
Base Surface Treatment: Clean the concrete base, remove loose particles and dust, and wet the surface with water until saturated but without standing water.
Mixing: Add measured water into a bucket, slowly pour in the powder, and stir for 3–5 minutes with an electric mixer until you achieve a smooth paste. Rest for 2 minutes and then re-stir.
Application: Apply the mortar with a trowel to the required thickness (single coat 5–30mm), compact, and smooth it out. For thicker repairs, apply in layers.
Curing: Spray water curing for 3–7 days after final set, and protect from direct sunlight and frost.
