TUFF-POXY Primer #3

Two Component


Epoxy Primer/Sealer


TUFF-POXY PRIMER #3 is a two-component, high solids, liquid applied, epoxy-polyamine primer.  TUFF-POXY PRIMER #3 is a low viscosity, quicker drying version of the TUFF-POXY PRIMER #1. The special blend of polyamine with small amounts of solvent gives unique penetrating characteristics and a rapid cure.  It has a low viscosity and improved adhesion to most substrates.


Basic Uses: TUFF-POXY PRIMER #3 is an epoxy polyamine primer suitable for use in all TUFFLEX Deck Coating Systems. It is specifically formulated to improve polyurethane elastomeric membrane adhesion to concrete and plywood and to properly treated metal.  TUFF-POXY PRIMER #3 is a solvent-based primer and does retain a light solvent odor for a short period of time.


Colors: Side-A: Clear & Side-B: Light Amber


Packaging:The TUFF-POXY PRIMER #3 is packaged in kit form. The VOLUME MIXING RATIO is 2 Parts Side-A to 1 Part Side-B (Side-A / Side-B = 2:1).


Sizes: TUFF-POXY PRIMER #3 is available in fifteen (15) gallon, (1-½) gallon and (¾) gallon kits.


Surface Requirements: Successful bonding requires structurally sound and clean substrates. The substrate must be cleaned to ensure that it is free of all oils, any laitance, greases or other contaminants, such as concrete curing compounds, which may cause poor adhesion of TUFF-POXY PRIMER #3. After cleaning, the surfaces should be rinsed thoroughly to remove loose particles and dust created during shot-blasting or grinding and traces of any cleaning chemicals which may have been used. Primers or detailing, membranes, etc. should not be applied until the surface is dry.


Mixing Instructions: If needed, this primer may be diluted with small amounts of Xylene or Toluene, to the extent allowed by the local Air Quality Management authority. Addition of solvent extends the work life of the mixture and provides better surface penetration. TUFF-POXY PRIMER #3 Side-A and Side-B should be thoroughly agitated prior to mixing to ensure a homogeneous material. TUFF-POXY PRIMER #3 must always be mixed in the ratio of two parts Side-A with one part Side-B (Side-A: Side-B = 2:1). The combined components should be thoroughly mixed for at least 2 minutes. No Induction time is required.


Application: TUFF-POXY PRIMER #3 should be applied at the rate of 1 gallon per 300-400 square feet. It can be applied using a brush, airless spray or by phenolic core roller.


Curing: Allow TUFF-POXY PRIMER #3 to become tacky to the touch (usually a typical dry time of 1-3 hours at 77ºF) before filling cracks, joints, or applying the base or detail coating.


Note: Temperature will affect the curing time of TUFF-POXY PRIMER #3. Higher temperatures will significantly accelerate the cure time while colder temperatures will significantly retard the cure time. To improve cure/bond time in cooler temperatures, TUFF-POXY PRIMER #3 may be pre-mixed and allowed to sit in the container for 10 to 15 minutes (the cooler the temperature, the longer the induction times) before application. In hot temperatures, the pot life of the primer / sealer is significantly reduced therefore the residence time in the container, after mixing, should be kept very short. Recommended application temperature is greater than 45ºF.


Equipment Cleanup: Equipment should be cleaned immediately after use with an environmentally-safe solvent, as permitted under local regulations. The primer is difficult to remove after it has cured.
