Damage & worming of concrete surface are always available in concrete making and providing cement surfaces. There are various factors including removing a part of concrete sticking to the frame at the time of releasing the frames, damaging a part of concrete because of armature corrosion, low quality of concrete and/or concreting process and also damaging or worming the surface, shocking the surface and unsuitable processing of concrete. For this purpose, we need a mortar for superficial repairs not only with the same properties of concrete but also has required adhesion and suitable granules. Modifier mortar has a cement base with specific formulation and special structure for modifying most of concrete surfaces and inside/outside surfaces of building. Concrete modifier based upon cement and find sands, polypropylene threads and co-polymer resins which is ready to use easily after mixing with water. Because of its specific formulation, this product has high level of adhesiveness for various concrete and cement surfaces with long-term durability. Concrete modifier has no more contraction and may not find any tracks out of contraction or shrinkage.
