concrete surface enhancer

Product introduction

Concrete surface enhancer is a water-soluble liquid chemical hardener with a colorless and transparent appearance. There are single-component materials and two-component materials commonly available on the market. The main components of concrete surface enhancers are reactive alkali metal silicates or modified alkali metal silicates, catalysts, additives, etc.

reaction principle

The concrete surface enhancer has extremely low surface tension and can quickly penetrate into the interior of the concrete. It reacts with the by-products of cement hydration in the concrete such as calcium hydroxide to form a large amount of silica gel. These gels can block The capillary micropores inside the concrete can increase the compactness, compressive strength, hardness and wear resistance of the concrete surface, which can generally increase the strength of concrete by 15-30%. In addition to generating silica gel, some hard and dense substances will also be generated, which will increase the strength of concrete more significantly. It can harden cement concrete floors with poor surface strength, dust and sand to the point where they are completely sand-free and sand-free. Can't afford ashes.

Scope of application

Concrete surface enhancer must be applied on the already formed cement mortar or concrete surface:

1. In order to ensure that the concrete surface enhancer can penetrate more into the concrete, it is recommended that the newly constructed cement mortar or concrete surface (preferably machine polished) be wet cured for at least 7 days and completely dry before construction. Of course, in order to save materials and construction time, some concrete surface enhancers are applied 24 hours after the new construction ground is completed.

2. Due to various reasons, the cement mortar or concrete floor surface layer is not strong enough and becomes dusty and sandy. Concrete surface enhancers can be used for hardening and dust-proof treatment: the surface hardness and wear resistance of the treated ground are significantly increased, making it unaffordable. Ash does not remove sand, but this treatment method does not change the appearance of the original floor. Therefore, it will not repair the damage to the original floor. If you want to repair damage to the original floor (such as potholes, cracks, etc.), you must use repair or overall polishing methods.

3.Surface sealing and enhancement of terrazzo floor or emery wear-resistant floor: If combined with machine grinding and polishing, both of these floors can have an effect similar to marble flooring.

Concrete surface enhancer is a water-soluble liquid chemical hardener with a colorless and transparent appearance. There are single-component materials and two-component materials commonly available on the market. The main components of concrete surface enhancers are reactive alkali metal silicates or modified alkali metal silicates, catalysts, additives, etc.

Construction method

The common construction method is to use low-pressure nozzles for spraying, such as using sprayers, rollers, and brushes. Apply evenly and fully. Spray the concrete surface enhancer evenly on the base surface, and polish the surface to promote penetration. When the water evaporates, the surface dries naturally. There will be obvious hardening effect after 24 hours. If the overall construction process is combined with polishing, the concrete surface enhancer will penetrate more thoroughly.

Precautions

This product needs to be stored away from light. The lid of the unused product must be tightened to avoid releasing air.
