As much as concrete is a popular and in-demand building material, it also requires protection and hardening. A huge number of liquid and dry hardeners for concrete surfaces, both freshly laid and already used, are presented on the market today. The price range of such materials is also very wide. In our article we will talk about a budget option for strengthening freshly laid concrete – a membrane-forming agent.
What is a membrane-forming device?
The membrane–forming agent is a liquid hardening agent for concrete, which is designed to strengthen freshly laid concrete surfaces and prevent premature evaporation of moisture, thus eliminating the formation of cracks.
It is also recommended to use the membrane forming agent in such cases as:
- Pouring concrete at high air temperature;
- Pouring concrete in strong winds.
If necessary, the concrete surface can be reinforced with dry topping on top of the membrane-forming agent.
What is the principle of operation of the membrane-forming device?
The method of hardening freshly laid concrete using a membrane-forming agent is much more effective for the classic ones that old-school masters like: covering with wet burlap, film or humidification.
Approximately 2-2.5 hours after application to freshly laid concrete, the membrane-forming agent freezes. A thin film forms on the surface, thanks to which moisture does not come out of the concrete layer prematurely, allowing the concrete to gain all its strength characteristics. Thus, we get a more durable, wear-resistant and dust-free surface without shrinkage cracks.
The membrane-forming agent looks very similar to concrete varnish. But they differ significantly both in characteristics and in cost (the membrane-forming agent is 2 times cheaper).
Among all kinds of membanoobrazovatel in the construction market, we advise you to pay attention to Teknokur 100. It is he who is distinguished by high quality and reasonable price.
What are the characteristics of the membrane generator?
- The membrane-forming agent can only be applied to freshly laid concrete.
- The membrane-forming agent retains moisture, which is necessary for the hydration of cement into concrete.
- The membrane-forming agent improves the mechanical strength of concrete.
- The membrane-forming agent prevents the appearance of shrinkage cracks in concrete.
- The membrane-forming agent can be applied to both cement and polymer coatings.
- The membrane-forming agent is very easy to use: it is applied immediately after the final grout of concrete with a spray gun, brush or roller in 2 layers.
