How can you choose the best wall coatings and what are the 5 most important tips to help you choose?
What exactly do we mean by “wall coatings”?
Smooth paints or textured coatings used to finish off walls are referred to by this term. They are mixtures with a fluid consistency made of various substances of mineral or synthetic origin that, when applied to a substrate, form a seamless, adherent coat. Their primary goal is to coat the surfaces to which they are applied in order to protect them from wear during use and from atmospheric agents, as well as to improve their appearance from an aesthetic standpoint by using different colors and textures.
What is the distinguishing feature of Mapei wall coatings?
Wall coatings are not finished products until they have been applied to a substrate. As a result, it is obvious that you must have a thorough understanding of materials and the interactions that occur between “substrates” and “finishing coats.” Mapei is able to offer coatings as part of a complete system in which the various products work in perfect harmony.
How do you select the best wall coating to avoid problems?
Most “diseases” that occur on exteriors are caused by a rather superficial approach to proposing finishing products, that is, without taking an integrated and global approach. As a result, various phenomena related to substrate and finishing product incompatibility exist, which, when combined with the use of a product with insufficient performance characteristics, are responsible for building deterioration. Because a coating product is usually the last layer or coat to be applied, it is the first, and sometimes the only, to be applied. A “visible” component of potential problems or damage caused by using insufficient or poor performing product cycles. Mapei Central Analysis Laboratory has the capability of examining the various pathologies encountered in constructions, determining the cause of deterioration, and verifying the efficacy of solutions. When coating products and paints are specifically designed to be perfectly compatible with surface repair cycles, they not only solve the technological problems of substrates, but they also maintain their aesthetic value for a longer period of time
What are the primary causes of wall coating deterioration? And what are the systems for dealing with them?
– Elastomechanical incompatibility: During the design phase, mistakes can be made regarding the use of materials with incompatible moduli of elasticity, which can lead to cracking and rainwater infiltration into masonry over time. Products from the ELASTOCOLOR line can provide a solution due to properties such as elasticity and water repellency. Chemical-physical variation: UV rays, acid rain, and smog are some of the main factors that contribute to the rapid deterioration of coatings. The QUARZOLITE system consists of acrylic resin- and micro-quartzbased products with good filling properties and high mechanical resistance, providing surfaces with increased durability and protection
– Biological deterioration: As a result of climate change, the phenomenon that causes mildew and mould to form on buildings has become a widespread issue. The water-repellence of siloxanes combined with BioBlock® Technology in the – SILANCOLOR PLUS system overcomes the problems associated with this type of deterioration over time.
– Rising damp: This is a problem that is common in areas near lakes or the sea. It affects a large number of residential and listed buildings, causing damage to both the paintwork and the underlying substrate. The synergistic action of Pozzolan-based MAPE-ANTIQUE dehumidifying systems and SILEXCOLOR and SILANCOLOR coating products is the ideal and complete solution for restoring and protecting masonry.
