  • For an optimal system and to achieve the specified level of permeability less than or equal to 0.1 perm according to ASTM E96, the following steps need to be completed. First use the clear version of the LABPOX MVB FAST for optimal adhesion and permeability. When the surface has been properly prepared, apply the first coat at 6-8 mils with a squeegee (no back roll) to allow a good seal of the surface and to minimize the pinholes phenomenon. Once dry, if there are pinholes, scrape to burst bubbles and clean. Then repair the pinholes using the LABPOX MVB FAST mixed with silica sand. While mixing the silica sand, make sure there is no air bubbles trapped in the mix. Then spread the second coat of LABPOX MVB to a minimum thickness of 8-10 mils (for a total of minimum 16 mils) using a squeegee and back roll to even out the surface. It is recommended to apply the product in a multidirectional manner (north-south, east-west) to ensure that the desired coverage rate is achieved. Then, continue building the system with a LABPOX epoxy. Any repairs before or during the application of the system should be made with the LABPOX MVB. No repair with CRACK FILLER, INSTANT PU REPAIR or POLYASPARTIC QUICK REPAIR is recommended as it will affect the permeability of the system.
