MVB Role

MVB: Why Moisture Vapor Barriers Matter for Epoxy Garage Floors. MVB stands for "moisture vapor barrier" and it’s a crucial part of 99% of coating applications that we do for grade-on-slab projects with epoxy garage floor coatings in Toronto, Mississauga, Vaughan, the GTA, Scarborough, and Brampton, making it an essential topic for anyone looking to protect their concrete floors. Below we’ll explain precisely what it does and why it’s necessary to prevent costly issues down the line with your residential epoxy flooring.

Moisture Prevention

Imagine concrete like a sponge—it has tiny holes that allow water vapor to come up from below the surface, and when you paint the sponge, the water vapor can push the paint off, causing it to peel and fail over time with your garage floor coating. To solve that problem, we use an MVB to create a protective layer with concrete coating services. The MVB creates a layer that significantly reduces the passage of moisture vapor through the concrete slab, acting as a shield that reduces the driving force for moisture to migrate through the concrete and into the coating, preserving its integrity with epoxy flooring Toronto.

Long-Term Protection

Think of it like this—imagine trying to blow air through a thick piece of plastic; the plastic acts as a barrier, making it difficult for the air to pass through, and similarly, an MVB acts as a barrier, making it difficult for moisture vapor to pass through the concrete and reach the floor coating, keeping it secure across the GTA. By applying an MVB coat, we prevent coating failures such as blistering, delamination, and poor adhesion, ultimately ensuring the longevity and performance of the floor coating for years to come. A slab with moisture should never be coated without this protection due to the risks involved—we always test our slabs prior to coating and mitigate future issues with a vapor barrier to guarantee success with your garage floor coating.
