The installation of low permeability flooring such as sheet vinyl, composite tile and polymer floor coatings over concrete with high levels of moisture vapor has been an industry problem for many years.  Even with better levels of education and awareness of potential flooring failure, the problem persists and creates millions of dollars in damages each year.  Beautiful and functional flooring installed over concrete with moisture issues can turn into a nightmare situation for building owners, contractors, flooring manufacturers and design professionals.  Assigning liability often ends in an expensive legal battle.
 
Arizona Polymer Flooring has formulated and manufactured specialized floor coatings since 1985 and has been a serious student of moisture related flooring failures for over 10 years.  We have developed a highly specialized epoxy coating system to remedy all levels of moisture intrusion.  Our moisture remediation library offers valuable information on understanding the dynamics of concrete moisture, accurate moisture testing, proper slab design to prevent moisture problems and information on our remediation system including product data, architectural specifications and warranties.  

EMS-P is a specially formulated water-based epoxy designed to provide superior adhesion over concrete with high levels of moisture vapor emissions. When used with the companion finish coat, 100% solids EMS, a coating system is achieved that reduces moisture vapor emissions to acceptable levels and maintains its bond under continuously moist, alkaline conditions. EMS-P is also an ideal primer over damp or green concrete. The product may be applied at temperatures between 40-100ºF. 

APF Epoxy Moisture Stop (EMS) has been formulated with low viscosity and excellent substrate wetting capabilities to promote penetration and adhesion to primed concrete.  The hydrophobic curing agent gives it the ability to cure fully over the primer that may be passing moisture vapor.  In addition, the product is crosslinked with Bisphenol F epoxy giving it very low permeability and excellent long term resistance to corrosive alkalinity.  EMS contains no plasticizers, phenols or unreacted amines that could migrate out of the cured coating and trigger osmotic blistering.
 
EMS Joint Filler is a specially formulated non-shrinking, flexible epoxy used for filling joints and cracks in concrete that is to receive the EMS coating system.  It is cured with a hydrophobic curing agent that allows it to cure fully in the wet, alkaline environment found in concrete with moisture problems.  EMS Joint Filler is modified with a novel raw material that is able to provide flexibility without compromising the water and alkalinity resistance of the material.
