P-99 3K MVS Primer


Product Overview

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.


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*.


The preparation method for each project is determined by a full understanding of the substrate to be coated, the chemistry of the coating system being used, the coating system thickness, and numerous other factors. The coating installer should fully read and understand ICRI Guideline NO.03732 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at lab@polymernation.com.

The data below represents the most pertinent information needed by a professional installer to understand and efficiently install this material. The data was gathered at temperatures of 72-75 F and 30-50% RH. A wide array of independent and company test data has been compiled on this product but is too large to place on this Technical Data Sheet.

Ideal Application Temperatures  60F-90F Verify that substrate temperature is above 5 degrees of dewpoint during application and cure of material to avoid a potential amine blush
Mixed Viscosity in cP@25C/77F 700-1000 Warmer temperatures will reduce viscosity and lower temperatures will increase viscosity
Gel Time 17-20 min. Warmer temperatures will decrease gel time and lower temperatures will increase gel time
Dry to Touch 3.25 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Through Dry 6 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Dry to Walk 8 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Dry to Lightly Use 16 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Full Cure 7 Days Warmer temperatures will reduce time and colder temperatures will increase time
Shore Hardness at 24 hours D65 Warmer temperatures will increase hardness
Shore Hardness at 7 days  D78 Warmer temperatures will shorten time to reach full hardness
Gloss @ 60 Degree Angle 80-85 Applying material close to dew point will decrease gloss and may result in an amine blush
VOC’s of Mixed Material  <50g/L EPA Method 24
Color Scale per ASTM D1500 .5-1.0 Clear to Slightly Amber
Solids by Volume Mixed 100%
Storage 60F-90F Store material between 60-90 degrees F in a protected dry location.
Odor Very Subtle
Application Thickness in Mils 16 mils in one coat or two 10 mil applications. See Mixing and Installation below.
Disposal Dispose of  material, containers, solvents, etc. per Federal, State and local guideline, rules and laws
Available Colors Charcoal, once part C is added.
Mixing & Installation Combine all of part A and B into a single container, large enough to accept the entire kit. Mix at 350 RPM for 3-4 minutes using an appropriate mixing blade and making sure not to introduce excessive air into the solution. Slowly add Part C and continue mixing for an additional 1 minute or until material is homogenous. Pour the entire content from the container onto the floor and follow normal squeegee and back roll or cut and roller techniques. Successful material performance requires a monolithic, pinhole-free finish. Achieving this finish is dependent on the substrate condition and the installers skill lever. While independent testing shows one, 16 mil application performs at a perm rate of .052/.068*, it is best, when performance is most critical, to apply in two, 10 mil applications and to test for holidays using a high voltage holiday detector. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
