Surface Treatment

This is a commonly used method of surface finishing. It is important for a residential floor to be smooth. To obtain a smooth finish, first the proportioning of mix should be appropriate. The finishing of surface should be at the same rate as that of placing of concrete. Attention must be paid to the extent and time of transportation. Careful attention should be paid to the non-formation of laitance, that excess mortar does not remain and excess water is not accumulated on the surface. A poor and dissatisfactory surface is formed due to hurried completion.

Rough finishes are required on concrete pavement slabs, air-field pavements, on roads, etc. In such cases, the concrete is brought to the plane level surface, and then lightly raked, broomed, textured or scratched to create a rough surface. Other finishes are to give good look like exposed aggregate finish.
