Before starting concrete polishing, one thing that is important is the preparation of the ground to be polished. This entire process is called densification and dust proofing. In this blog, you will read about 5-step concrete polishing including densification & dust proofing. Our concrete is a porous surface and is always exposed to dirt & dust. So, to get a dust-proof floor, we have to densify & dust-proof the surface.

A concrete floor can look dull & dusty because of the fact that it is a porous surface.

This is a 5 step process of making a concrete floor look dustproof. In the present-day scenario, domestic and commercial construction projects are on the rise. In order to have a long-lasting and durable project, the contractors in the construction industry use concrete heavily. However, cement is very delicate and needs to be handled with care in order to get the required results. With the help of this blog, the readers are going to learn about some important steps of concrete polishing that will help to hold a long-lasting and durable concrete floor. CONSTRUCTION: Whether you are a home builder or in the business of construction, we seek to provide you with a hint of tips and solutions that would select you to take your project to a new height of success.

What is densification?.

Densification is a way to fill up the open spaces on a concrete surface. This is a method used by many people to cover up the existing floor’s imperfections. Though densification is applied to the concrete, it is important to have a good solid concrete surface to start with. The densification works by adding a resin and filler to the concrete surface and then the concrete is re-polished to give a smooth surface. A densifier is applied to the floor and then it is left for a few hours. During this time the densifier gets soaked into the concrete and fills up the open spaces. The floor is then polished and the process is completed. The densifier can be applied to the floor a few times. This will make the concrete even denser and will make it last longer. Densification works by filling up the open spaces in the concrete. This helps the concrete surface to be more durable. It also gives the floor a neat and professional look. Densification is the method used to keep the concrete flooring dust-free & dustproof, which is created by applying a liquid densifier to the floor. Applying liquid densifiers to the concrete floor, it creates a water-tight barrier between the concrete surface and the environment. It also preserves the floor by protecting it from water damage and staining. The densifier can be either oil-based or water-based but it is best to use a water-based densifier as it is more environmentally friendly than the oil-based densifier.

What are the benefits of densification?.

One of the key benefits of densification is that it extends the life of the polished concrete. Dust, dirt, and other contaminants are sealed into the pores of the concrete, making it difficult for them to penetrate the concrete surface. By densification, concrete becomes more durable, reducing the damage and thus prolonging the useful life of the surface. Densification is the process of preparing concrete surfaces for flooring or paving. It is a wet process using liquid densifiers which are chemical solutions that are applied to the surface of the concrete. Densifiers are applied to the surface of the concrete to make it porous so that the concrete can be polished to a high gloss finish ready for flooring and paving. The concrete floor surface can be densified using a number of densifiers, including liquid acrylics, solid acrylics, epoxy resins, and urethanes. Densification reduces the strength of the concrete, so it is only applied to concrete that is not needed to bear any load.

Conclusion: Densification is different than dust proofing.

  1. Concrete may be polished either dryly or wetly. Although each has benefits, dry polishing is the technique that is currently most frequently employed in the sector since it is quicker, more practical, and environmentally friendly. Water is used in wet polishing to cool the diamond abrasives and get rid of the grinding dust. Water prolongs the life of polishing abrasives by reducing friction and serving as a lubricant. The cleaning is this method's main drawback. The slurry produced by wet polishing is enormous, and teams must collect it and dispose of it responsibly. There is no need for water during dry polishing. Instead, a dust-containment device that is connected to the floor polisher almost eliminates the problem.
