What are the best tips for concrete sandblasting?

Some of the best tips for concrete Sandbasting are surface preparations, ensuring all surrounding materials that can be damaged, and create the right machinery technique with the machine. The type of sand should also be considered before the project started. In addition, all neighbors or spectators should be cleaned in the area.

Sandbasting concrete is a common way to rejuvenate the surface after many years of unsightly spots, for example along the home driveway. The preparation of the concrete surface is an important step; All objects on concrete, such as tree branches or pebbles, should be removed. Any debris that remained on the concrete during sandstone will immediately become projectiles that can damage the property or people around.

This form of concrete rejuvenation uses a machine that pushes high -speed sand across the target surface. As a result, any wooden objects or plants near concrete should be covered with a tarpaulin; High -speed sand can easily createt small indentation in plant leaves or on the borders of wood. If possible, it is a good practice to remove any sensitive objects in the sandbasting area. Some house owners can even place plywood panels around the concrete area to prevent any sand to leave the immediate area.

Another tip for concrete is the right technique. The sandstone wand should be held at an angle to the concrete surface, preferably about 18 to 24 inches (46 to 61 cm) above the ground. The blasting process may require some practice at the beginning; The walking speed must be stable, but not too fast, otherwise the concrete blasting will not be so effective.

Beginners who want to perform their own concrete project with sand should first try a small area. A person can choose a corner of concrete that is slightly off the road; He or she can practice the thv area blasting until she reaches the desired appearance.This area of ​​practice prevents beginners from unintentionally damaging the main part of the concrete if the blasting technique is not yet managed.

Most of the concrete projects use silica sand as the main abrasive agent; Other sands can be used if they have a consistent size throughout the mixture. In addition, the type of sand should be relatively fine in size; Larger sand granules create a larger insertion on the concrete surface. The main goal of the sandpit is to remove a fine layer of concrete from the immediate surface, unlike the irritation of large pieces of concrete with larger sand granules.
