In earlier entries, we discussed how the correct floor covering may benefit commercial and industrial facilities, as well as how equipment and machinery might benefit from a fresh coat of paint. Just as these inner elements of an operation require good surface coverings to protect them from wear, tear, grime, and grease, your structures’ exteriors require paint to protect them from the destructive impacts of the elements. Preferred has you covered for all of your industrial paint and surface covering needs. Here’s what you should know.
Reinforcement Bar Corrosion:
Moisture enters the metal re-bar framework at the core of most concrete structures, causing this to happen. The deterioration of a building’s metal infrastructure is expected to become a devastatingly expensive problem in the future.
Expansion of the Aggregate:
This happens when small stones and sand in the concrete mix absorb moisture and expand, causing cracking and crumbling. This phenomenon is frequently caused by silica in aggregate reacting with alkali components in cement. Locking out moisture with paint will prevent or limit aggregate expansion because such chemical reactions can only occur in a solution.
Carbonation occurs when naturally occurring carbon dioxide in the environment reacts with calcium hydroxide in concrete to generate calcium carbonate. This process raises the acidity of concrete, which promotes the corrosion of metal reinforcements over time. As a result, a good coat of paint by office painters in Sydney will keep air CO2 and other chemicals out, reducing carbonation and other forms of chemical breakdown.
