They keep the surface breathable, allowing it to evaporate the vapors. This concrete sealer survives for a long time and requires reapplication after five years.


  1. Durable Coatings – Durable coating when applied to the surface of concrete leaves a glossy finish with a hard and chemical-resistant layer. They are available in various colors for the trending floors with upcoming designer interiors. They are mostly used for interior applications as they turn yellowish when exposed to UV rays.
  2. Decorative Coatings – You can use decorative coatings for both interior and exterior applications. Being available in a wide range of sheen levels, they leave the surface with a glossy finish. They change the look, texture, and appearance of the concrete surface.
