Abstract: The present invention relates to a method of producing a water repelling surface or imparting hydrophobicity onto a surface comprises applying a polymer-based coating composition. The water repelling surface or the hydrophobic surface imparted by the present method has at least 90° of water contact angle. The water repelling surface or the hydrophobic surface imparted by the present method is preferably on a concrete surface. The present method imparts hydrophobicity onto surfaces that are durable without an additional primer layer between the surfaces and the coating composition.

Abstract: The present invention provides a composition for forming a lightweight, low shrinkage and hydrophobic cementitious matrix, and a method for preparing thereof. The present cementitious matrix formed by the composition is lightweight, hydrophobic (or water repelling) and with low shrinkage which is useful in building and construction industry as non-structural wall resistant to water, heat and sound entry. The present invention also provides a method of preparing the composition and the cementitious matrix formed from the composition.
