L&M E-CON

[Free Sample Available] A concrete placement aid that reduces moisture evaporation by up to 80%, allowing concrete to cure slowly without cracking even during summer placements.

Concrete, when exposed to conditions such as direct sunlight, wind, and low humidity immediately after pouring, experiences rapid moisture evaporation, leading to the occurrence of shrinkage cracks and the formation of a porous, weak concrete with a rough texture. 'L&M E-CON' is a concrete placement aid that, when diluted and sprayed during the pouring of fresh concrete, can reduce evaporation caused by wind by up to 80% and evaporation due to direct sunlight by up to 40%. The pink liquid makes it easy to see where it has been applied, preventing uneven application. Additionally, its effects of moisture evaporation suppression and delayed curing facilitate smoother finishing work on the concrete. [If you have ever experienced any of these issues, please try a free sample!] ■ Fine cracks ■ Porous surface ■ Surface irregularities ■ Color differences at joints ■ Surface peeling ■ Trowel marks *For more details, please refer to the materials. Feel free to contact us with any inquiries.

When used during concrete placement in logistics and commercial facilities finished with Seal Hard, the appearance of the concrete after application will be beautifully finished. ■ Cures slowly even during summer concrete placement, allowing time for trowel work. ■ Can be applied over a wide area (approximately 2000 square meters with a 5-gallon can). ■ Easy to identify sprayed areas, reducing the risk of double application.

Applications/Examples of results

Please use this in the following cases to improve concrete quality and reduce initial cracking: - Concrete pouring in summer - Concrete pouring in direct sunlight without a roof - Concrete pouring in exposed areas without walls - Concrete pouring in dry, low-humidity conditions It is especially recommended for use when pouring concrete floors that are planned to have a seal hard finish. It helps to suppress moisture evaporation from the concrete during pouring, prevents the porosity of the concrete, and enhances the finish quality after seal hard treatment. E-CON is effective during the initial curing period, which is very important for concrete, for about 4 hours after pouring, but please carry out separate wet curing after the day following the pour. If wet curing with sprinkling, curing mats, or polyethylene film is difficult, we recommend the water-based curing agent "CURE," which can be applied easily. By using E-CON and CURE together on concrete substrate finished floors, you can achieve a concrete floor with fewer cracks and color variations, pleasing to the client.
