It is important to use a moisture control product before adding a coating to concrete because moisture vapor transmission can cause significant damage to the coating and the underlying structure. When moisture vapor passes through the concrete, it can create a barrier between the coating and the concrete surface, leading to adhesion failure, blistering, and peeling of the coating.
By using a moisture control product, such as the moisture control epoxy material systems mentioned in the article, you can create a strong and durable barrier against moisture. This barrier prevents moisture vapor from reaching the coating, ensuring proper adhesion and protecting the coating from damage.
Using a moisture control product also helps to maintain the integrity of the concrete itself. Moisture can weaken the concrete and lead to issues such as cracking, spalling, and deterioration. By stopping moisture from penetrating the concrete, the moisture control product helps to preserve the structural integrity of the concrete.
In summary, using a moisture control product before adding a coating to concrete is important to ensure proper adhesion of the coating, protect the coating from damage, and maintain the structural integrity of the concrete.
