Vinyl Wash Primer
A two component pretreatment primer for use on properly prepared steel, aluminum
and galvanized metal.
For industrial and commercial use including piping, structural steel, marine vessels,
storage tank exteriors and roof decking. For use as a pretreatment primer to promote
adhesion of recommended topcoats on steel, aluminum and galvanized metal.
Vinyl Wash Primer is a reactive pretreatment which etches and passivates the substrate
and improves the adhesion of recommended topcoats. Fast drying for quick recoat time.

Unit Shipping Weight 9 lbs. 42 lbs.
Shelf Life - 12 months minimum from date of manufacture when maintained in protected
storage @ 40-100oF (subject to reinspection thereafter).
Limitations: Apply in good weather when air and
surface temperature are above 40oF and surface
temperature is at least 5oF above the dew point. For
optimum application properties, material should be
between 70o to 100oF prior to mixing and application.
Maintain unmixed material in closed containers in
protected storage at 40 - 100oF.
Surface Preparation: Good surface preparation is
essential to a satisfactory coating system. Surfaces to
be coated should be clean and dry. Remove all oil,
grease, mildew or other contamination by solvent or
detergent cleaning or other effective means.
Steel - For best performance, application to abrasive
blasted surface is recommended. “Commercial Blast
Cleaning” (SSPC-SP6) is recommended as the minimum.
Proper blast media and blasting equipment shall be used
to produce an average profile depth of 1.5 mils minimum.
Do not reuse abrasive media. Remove blasting dust and
grit from surfaces before painting. Blasted surfaces
should be coated within 8 hours after blasting or before
rusting or other contamination of the surface occurs. If
blasting is not feasible, remove rust, mill scale .
Galvanized Steel - Remove all oil or other contamination.
Aluminum - Clean thoroughly to remove oil or other
Previously Finished Surfaces - This coating must be
applied directly to properly prepared surfaces above.
Any previous coating must be completely removed.
Mixing: VINYL WASH PRIM is supplied in 2
containers as a unit. Always mix a complete unit in the
proportions supplied. (1) Agitate Part A Resin Component
with power agitator. Special care should be taken to
completely redisperse any settled pigments. (2) Combine
entire contents of part A with entire contents of and Part
B Acid Component and mix thoroughly with power agitator.
Material should be used within 8 hours.
Thinning: This product is supplied at normal spraying
viscosity. If thinning is necessary thin with HJ-1701.
Application: Apply by brush or conventional or airless
spray. Apply at a spreading rate of approximately 314
square feet per gallon which will yield a dry film thickness
of 0.5 mils.
Topcoating - Allow this coating to dry 12 hours before
topcoating with epoxy coatings containing strong
solvents. This product is not designed for exterior
exposure and should be topcoated within 24 hours.
Equipment: Brush - Use a good quality bristle brush.
Cleanup: Clean all equipment immediately after use
with HJ-1701. Completely flush all spray
equipment with this solvent. Occasional flushing of spray
equipment during the course of the working day helps
prevent buildup and possible clogging.
Safety: Safe storage, handling and use dictate that
adequate health and safety precautions be observed
with this product and any recommended thinners. User
is specifically directed to consult the current Material
Safety Data Sheet for this product as well as precautions
contained on product labeling.
