Polymer Nation P-99 3K Moisture Vapor Suppression Primer
Product Overview
Polymer Nation P-99 is a state of the art, moisture vapor suppression system epoxy primer. It employs a modified epoxy backbone to achieve deep penetration and alkali resistance. This deep penetrating, tenacious bonding material, when properly installed, reduces moisture vapor emission rates, through concrete, to .1 or less. This allows for subsequent coating of troubled concrete with non-permeable floor finishes.
Uses and Benefits
Polymer Nation P-99 is used when concrete testing, per ASTM F2170, shows average RH readings between 75% and 99% or when moisture vapor emissions are suspected, and an additional level of moisture protection is desired. P-99 is installed directly to properly prepare concrete. Testing shows P-99 performs well both on concrete prepared to a, ICRI, CSP 2 and CSP 3*.
