Anti-Carbonation Coatings

Carbonation of reinforced concrete is one of the most common forms of deterioration in buildings and infrastructure. Untreated masonry is also highly vulnerable to water ingress and freeze-thaw cycling damage.

Carbonation is a natural process that begins as soon as concrete is exposed to the elements, making it virtually impossible to avoid in unprotected concrete. Atmospheric carbon dioxide reacts with concrete, leading to a loss of alkalinity and subsequent corrosion of reinforcing steel. This can severely compromise structural integrity.

Specifying anti-carbonation coatings is critical for both new and existing structures. These protective coatings ensure buildings remain visually attractive throughout their lifespan while avoiding costly, disruptive repair and maintenance work in the future.

Handling and Storage of Paints

Paints and other flammable materials must be kept in properly sealed containers. These containers should be stored in well-ventilated locations, free from excessive heat, smoke, sparks, or open flames.

All paints must be stored strictly in accordance with the manufacturer's requirements. The storage area should be:

• Well-ventilated
• Protected from sparks and flames
• Shielded from direct sunlight and excessive heat
• Preferably located in an isolated room or separate building

All paint containers must be clearly labeled with:

• Paint identification
• Date of manufacture
• Batch number
• Order number
• Special instructions (in legible form)

Containers should only be opened at the time of use. Paints that have livered, gelled, or otherwise deteriorated during storage must not be used. Paints past their manufacturer-specified shelf life cannot be used without inspection and approval by the engineer.
