There have been numerous attempts in the past to repair cracks instead of the cost-effective alternative of taking concrete off and repouring. Despite all the efforts , concrete crack repair methods did not always work because of flaws in the product’s capabilities Crack Repair.
It is the Next Generation of Repair Products
The development of concrete products was taught by coatings. For instance, Acrylic sealers have been the cheapest coatings and have been used for many years to shield concrete surfaces. They have led to the use of urethanes and epoxies which were the most common industrial coatings for a long time. There have been variations. These are however simple chemical mixtures with very little variation.
In recent times, polyurea and polyaspartics have been created that are complex chemicals that when combined create distinctive results. Polyureas possess the ability of being able to “wet” in concrete. This means that when they are applied to a cement surface that is porous, they soak into the concrete the way sponges absorb water instead of adhering to the surface like tape does, which it is with Epoxies. After the polyureas cure, they will become part of the concrete.
They are the top of the line in development of repair and coating products.
Characteristics of Polyaspartics as well as Polyureas
As previously mentioned, polyureas will absorb into the surface of a cement that is porous. Polyaspartics can be added to polyureas that can make it more difficult or less effective to duration of cure based on circumstance. This is a unique process with an experienced and skilled applicator. The dosage can be altered according to the climate and temperature. In hot weather conditions such as Florida the time to cure can be reduced, and in Minnesota the time to cure can be extended. This has created new markets and possibilities to coating application professionals. For instance , a garage flooring can be replaced in just a few hours, with an outcome that takes three or four days to produce a product that is superior to epoxy.
For industrial and commercial floors, the results are more extensive. The ability to cure quickly allows the applicator to use a highly efficient coating, without the need for the business to stop operations. This can save the business money and creates new opportunities for the applicator.
Polyureas as a Crack Repair Product
Concrete is among the most frequently used materials in the world and it never cracks. Crack fillers, until recently, lacked some crucial elements that stopped them from working. They are usually too thick to reach the crack’s bottom. Cracks are rarely straight. A four inch wide cracked slab could include a dogleg part way down. If the filler for cracks is too thick, it could stop at the angle at which it was first. The issue is that cracks are like vents for water and vapor. If the crack isn’t filled up to the bottom, the moisture vapor can travel into the crack and push hard to push the weak point away from the way.
The other major problem is that crack filler needs to set beneath the surface, and often the surface is damp. Moisture vapor that moves upwards through cracks will cause the porous walls of the fracture damp. Crack fillers have no chance. They tend to stay wet and don’t cure. In the past, it was believed that what you don’t see isn’t harmful.
Imagine those millions of crack filler around the world that don’t work. Polyureas are the solution to that issue. Be aware that not all polyureas are identical. They can, however, be sufficient in thickness to pour into cracks and then flow towards the end. Like I said earlier, they can be soaked into concrete, so when poured into cracks, they are infiltrating into the walls, and eventually become an integral part to the structure.
They are amazing and true that they can be cured beneath the surface and be activated by humidity. They can also flex in response to moves within the floor. They are not just an exceptional crack repair product however, polyureas are also able to fix flaws in the floor. In reality, polyureas are employed to fix floors that look as if they are hopeless.
