🛡️ MVB Moisture Vapor Barrier Epoxy Primer
Bond Craftor MVB is a two-component, 100% solids epoxy primer designed for properly prepared concrete surfaces. It helps reduce moisture vapor transmission through concrete, minimizing coating failures such as bubbling, peeling, and delamination.
With strong concrete adhesion and self-leveling flow, MVB forms a uniform primer layer and provides a reliable base for epoxy floor coating systems, flake, and polyaspartic coating systems.

💧 Key Performance
01
Effective Moisture Protection
Helps reduce moisture vapor transmission through concrete, minimizing coating failures such as bubbling, peeling, and delamination.
02
100% Solids
Solvent-free formulation with minimal shrinkage, forming a dense and durable protective layer.
03
Fast Cure
Initial cure occurs in approximately 4–6 hours at 25°C, with full cure within 48 hours.
04
Strong Concrete Adhesion
Bonds firmly to properly prepared concrete, creating a reliable base for epoxy, flake, and polyaspartic coating systems.
05
Self-Leveling
Provides smooth flow and easy application, creating a uniform primer layer.
06
Industrial-Grade Durability
Cures to form a hard, chemical- and abrasion-resistant primer layer that supports long-term performance in demanding floor coating systems.
