This educational construction video tutorial is specifically created for home owner, business owner, contractor, finisher as well as improving your knowledge about concrete.

This video is presented by John, co-founder of Concrete Genius. In this video John covers some vital topics in concrete construction which range from type of concrete sealant applied in concrete, concrete hardener and concrete densifiers.

Concrete should sealed with a powerful sealer as concrete is an absorbent material that quickly consumes liquids. In freeze-thaw weathers, the enlargement of frozen liquids can devastate the surface of unsealed concrete. Besides, oil, salt, fertilizer, and other household chemicals can affect the color as well as impair the unsealed concrete.



One can apply various sealers independently with the use of simple tools, like a paint roller of pump-up sprayer. These comprise of acrylic-resin sealers, reactive penetrating sealers, 50%-solids epoxies and 50%-solids urethanes. To apply high-quality sealers like 100%-solids epoxies, polyaspartic urethanes and polyureas, professional guidance is necessary with special tools and application techniques.
