Concrete seal hardeners are liquid compounds that are used to harden concrete surfaces to enhance their surface hardness, abrasion resistance, and reduce the penetration of liquids or gases. These liquids or gases such as water, deicing salt solutions, and carbon dioxide can cause freeze-thaw damage, steel corrosion, Acid corrosion. In addition, concrete seal hardeners are used in indoor concrete floors to reduce dusting and penetration resistance, making the surface easier to clean.
Concrete seal curing agents can generally be classified into film forming and penetrating.
The film-forming seal curing agent mostly covers the surface of the concrete and only a small amount penetrates the concrete. This relatively large molecular encapsulation of the curing agent limits its ability to penetrate the concrete, ie, dilution with a solvent does not improve their penetration capabilities. These materials can not only reduce water penetration, but also resist mild chemical attack. In addition, they can prevent concrete from absorbing grease, and can also reduce ground dusting and sanding caused by pedestrians and vehicles.
Film-forming seal curing agent consists of acrylic resin, chlorinated rubber, polyurethane, epoxy resin, etc., such as epoxy resin wear floor, polyurethane floor, etc., which are most widely used in industrial flooring. The effectiveness of the film-forming seal curing agent depends primarily on the continuity of the formed coating. Gravel abrasions and frequent pedestrian and vehicular traffic can damage the coating and require repainting. In addition, some film-forming sealing curing agents, such as epoxy resins, may yellow and accelerate aging under UV light.
Permeability concrete sealing curing agent is generally composed of silane, siloxane, silicate, fluorosilicate, etc. It can effectively penetrate the concrete surface 3-8 mm, and reacts with some free components in the concrete to produce a kind of Hard and dense material, the concrete treated with this sealant curing agent, its hardness, compressive strength, wear resistance, anti-permeability, anti-aging properties can be greatly improved, thus greatly prolonging the service life of concrete.
The use of any type of concrete seal curing agent should ensure that the concrete must be clean and dry at temperatures above 16 degrees Celsius for at least 24 hours. It takes at least 28 days for newly poured concrete to use the sealed curing agent because of the porosity of the concrete surface. Filled with water, penetrating concrete sealant hardly penetrates into these pores. In practical applications, the newly-constructed concrete has just been completed (some of them for a week or so) and concrete curing agents have been used. In this case, the penetration depth of the concrete sealing curing agent is very limited, and the hardened and sealed concrete is often only the concrete surface. A very thin layer.
Concrete seal curing agents have very good effects on the defects of the old concrete or cement mortar grounds such as sanding, dusting and dusting, etc. Of course, if the old concrete floor is dirty, the surface must be treated as necessary.
Because the concrete seal curing agent can retain water and may exacerbate freezing and thawing, do not use it in winter and when the temperature is close to or below zero degrees Celsius.
