These functional coatings are able to have properties which are innovative and impactful and can significantly contribute to improving living life environmental comfort level. Disturbance of domestic ambience by external chemical and biological intruder have a direct impact on general hygiene and safety. Although a significant progress has been made in modem science to tackle these problems, which is functional coatings. Here, some of the functional coatings will be discussed and their impact on human health, comfort, safety and hygiene. Introduction of functionalities is the key for developing coatings with desirable properties, for example nano particle and polymers having antimicrobial properties when incorporated in coatings can easily improve the overall hygiene there by health. In similar fashion Piezo electric materials, when applied to coatings can detect damage sites in buildings, thus, increasing the general safety. Furthermore, phase changing materials and coatings that can convert sunlight to electricity offers alternatives for maximizing output from natural resources providing a much sustainable environment.

Review of waterproof painting techniques by using suitable technology / Sunil Khairnar in PAINTINDIA, Vol. LXV, N° 12 (12/2015)  

[article]  inPAINTINDIA > Vol. LXV, N° 12 (12/2015) . - p. 53-63 Titre : Review of waterproof painting techniques by using suitable technology Type de document : texte imprimé Auteurs : Sunil Khairnar, Auteur ; Ashis Kumar Khan, Auteur ; Rajeev Kumar Goel, Auteur Année de publication : 2015 Article en page(s) : p. 53-63 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Efflorescence Etanchéité Humidité Imperméabilisation Matériaux bitumineux Membranes (technologie) Nanoparticules Nanotechnologie Polymères Revêtements -- Défauts:Peinture -- Défauts Revêtements en bâtiment:Peinture en bâtiment Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : Aesthetics of the building is a major reason behind the painting of interior and exterior surface of the building ; Painting provides beauty to the building and covers little defects present on the substrate (masonry, wood or metal). The paint works as a building envelope but still it is affected by nature's elements like wind, rain, mist and dirt and dust. Water and moisture are the major things which affects the performance of interior and exterior paint applied on the building. In general the paint performance related problems are increasing due to increasing complexity in construction practices. The performance of bath interior as well as exterior paints can be improved significantly by using proper waterproofing solution along with a recommended painting system. If water seepage coming from groundwater, rainwater and surface water can be adequately controlled, it would prevent damage of coating system and avoid requirement of unnecessary repairs to building envelopes. ln fact water is the must destructive weathering element of concrete, masonry and natural stone structures and its damage continues until the structure is destroyed completely. Waterproofing techniques preserve the structural integrity of the building. Recommendation of waterproofing system involves understanding of natural forces affecting the performance of coating system as well as various designs of waterproofing rnaterial. This paper involves, in solving the problems arising in interior paint due to water and moisture seepage or ingress using combination of proper coating system by combining it with proper waterproofing solution.
