Floorings are hard, but not always hard; with the time the cracks starts to appear and often starts to wear out before time. To increase their longevity; floor hardeners are used. It acts like a concealer that ensures the flooring doesn’t get damaged for a longer time.
What’s the theory of using Xtreme Polishing Systems floor hardeners?
Usually, these floor hardeners work like this:
The usual flooring contains calcium carbonate, lime which plays an important role in strengthening and making it durable. However; the chemical reactions don’t reach every last bit of the cement.
With the growing trend within the concrete flooring industry is to apply the floor hardeners on freshly-troweled concrete in what is referred to as a pre-seal. Professionals/workmen specialized in flooring treatment advises to apply hardeners within 28 days of time after the concrete surface has laid out which gives maximum performance.
Professionals at Xtreme Polishing Systems recommends 28 days based on their strong understanding of the chemistry behind floor hardeners and the means by which they densify concrete surfaces.
Now the theory
Day 1 to Day 28
On day 1 the hardeners have less or no time to hydrate within the concrete slab as it the concrete flooring still has calcium hydroxide which takes time to react with the hardener. Also, the presence of water prevents floor hardeners to enter deep into concrete.
The hardener by this time is not able to enter concrete apertures and with the constrained expanses of calcium hydroxide to react with, it remains on the concrete’s surface and reacts with the air to form unusable, salts.
Conversely, after 28 days of hydration, pores and capillaries are theoretically free of excess mix water and calcium hydroxide is abundant. Hardener has way to penetrate into the capillaries’ and pores beyond the concrete surface, and reacting it with the calcium hydroxide during the course of the slab which generates calcium silicate hydrate gels.
The performance of floor hardeners are limited when concrete to be treated lack a sufficient amount of calcium hydroxide, or when it is unable to penetrate due to the surface being saturated with water.
Testing Is Done
For testing the concrete flooring whether the hardeners have worked or not; 2 abrasive wheels are moved onto the surface. Scratches and scruffiness is measured by the amount of ground up concrete removed from the surface. Concrete dust, debris is then collected from the specimen and evaluated on an analytical balance. The more concrete debris removed and collected, the more heavily scuffed the surface.
Floor hardeners play an important role which one should not overlook. Taking in its significance and with the industry demands, which not only takes care of the foot traffic demands but ensure that one doesn’t have to undergo costly flooring replacing treatments. Also; engage yourself with basic understandings of these hardeners as they are available in variety serving different purposes.
These are not easy DIY projects; hence xtremepolishingsystem.com offers a very detailed understanding of using one. It is also consults on various professional flooring services; it is advisable to get suggestions and guidance from experienced professionals especially when you are dealing with an expensive project.
