Sodium Silicates as Concrete Sealers: Interesting Facts to Know About
Sodium silicate sealers are extremely popular for use on both the interior and exterior concrete portions. Over the past years, there has been a sudden surge in demand for silicates as they act as concrete sealers. Generally, sodium silicate sealers penetrate the concrete’s surface, chemically reacting to form a calcium silicate hydrate structure. The end product is visible within the pores that bind the concrete firmly.
The sealers can spark another chemical reaction within the concrete that conceals all the pores within it. So, after all this, only the calcium silicate hydrate structure remains, which hardens over time. Such chemical reactions are responsible for the hardening of concrete. So, let’s take a little close look at some other facts about these sodium silicate sealers:
No Control Over CSH Structure Formation
An interesting fact about CSH structure formation is that you can never predict or control its size. Therefore, you need to put multiple coats as the size can depend on the amount of calcium and free lime present within the concrete during application. The size of these structures also depends on the particular method of application, density, the porosity of the concrete surfaces along pH, moisture, etc.
CSH Structure Remains Identical
The CSH structure is always identical, no matter which brand you decide to use for the application. Remember that a silicate will always be a silicate. So, no matter what brand you utilise, it is about the percentage of sodium silicate that determines the chemical reaction’s fate.
Never fall for the false warranties or any claims that many brands might make for selling their product. Only its amount and quality will be responsible for delivering the results. If you want to get such premium quality sodium silicates, ensure investing in finding the best sodium silicate machinery exporters in the market.
