Bostik - Mvp4 Moisture Vapor Protection

Does not spread as claimed. After it dries, it has ridges and there will be a need to buy twice the amount of adhesive. Plan on buying twice the amount of MVP4 for stated coverage because it does not flow as shown in their own videos. Does not adhere to concrete causing a noisy floor. Does not create a vapor barrier. And when you make a claim with Bostik, they will never return your calls forcing you to hire a lawyer if you want your money back. A total waste of money and work to not only install, but to tear up an entire floor and redo with new flooring. Use only if you have no moisture problems at all including only if the humidity in your area never goes above 25%.
