A COAT OF PROTECTION How can protective coatings strengthen, enhance and improve the lifespan of buildings?

or architects and designers, creating a building that will stand the test of time is paramount. However, the longevity of a structure can be compromised if its components aren’t protected. Here, Tony Walker, Technical Specification Controller at PPG Architectural Coatings, explains how specifying advanced, protective coating solutions earlier in the design phase can significantly bolster our buildings. Years of hard work go into designing and constructing a building, so it makes sense that we should do all we can to keep them in top condition and resistant to damage throughout their lifespan. However, too often this level of effort and attention is only brought in as a remedial measure when decay and damage have already had an effect, resulting in a much more costly, disruptive and difficult process. One area that can provide real value here is the specification of well-thoughtout coating systems. Rather than being just a ‘lick of paint’ that’s only considered at the

end of a project, coatings need to be a key consideration early on in the specification process if we’re to create assets with true staying power. After all, they are the outermost barrier between the building and external forces. To help architects safeguard their buildings, there’s a vast array of protective coatings available that are specifically suited to different substrates and materials.
Fighting fire with coatings Steel is most commonly used for large buildings due to its natural strength. However, if left exposed, even for short periods of time, steel will rust and eventually corrode, leading to structural fatigue and instability. This can pose serious health and safety risks, particularly in areas such as fire escapes, which can become compromised if the steel structure breaks down considerably. Anti-corrosive paint systems are available for the protection of such structures, which can help prevent rust formation and enable the material to retain its strength.
