P/G PRIMER
DESCRIPTION
P/G PRIMER is a solvent-based, two-component
primer system for use with GARDOX® and DECK-O-
SEAL®. It aids in the adhesion of joint sealants
to the interfaces of expansion joints in masonry,
swimming pool decks, concrete, or wood.
PACKAGING
P/G PRIMER is available in one-quart containers,
packaged three per carton.
COVERAGE
Depending on the porosity of the surface and joint
dimensions, one (1) quart of P/G PRIMER will be
sufficient for 5 - 7 gallons of sealant.

APPLICATION
Surface Preparation …Prior to application of P/G
PRIMER, joint surfaces must be structurally sound,
clean, dry, and free of oil, grease, dirt, and loose
particles. Remove all curing compounds and form
release agents from joint surfaces. Joints must be
clean of bituminous materials and bituminous-impregnated
joint fillers. Control depth of sealant
using KOOL-ROD™ backer rod from W. R.
MEADOWS. All joints subject to total immersion
in water MUST be primed with P/G PRIMER.
Control depth of sealant subject to submersion with
SELF-EXPANDING CORK EXPANSION JOINT
or CORK EXPANSION JOINT from W. R.
MEADOWS or suitable expansion joint to support
the weight joint sealant is subject to. It is
recommended an engineer be consulted for
calculation. Note: Submerged joints should only be
sealed by a professional and/or trained contractor.
Mixing…Components are pre-measured to
exact quantities; mix all material in both
containers. Pour part A into part B and mix
thoroughly with a clean wooden or metal paddle
for approximately 3 - 4 minutes. Scrape container
sides and bottom for complete integration. After
mixing, work life is approximately five hours at
70° F (less at higher temperatures).
Application Method … Apply P/G PRIMER to
properly prepared joint surfaces by brush,
depositing a light, continuous film. Normally one
coat is sufficient; however, two coats should be
applied to very soft, porous surfaces. Do not
over-apply. Use caution when applying in joints
with backer rods. Over-application onto backer
rod can cause it to shrink and dissolve. PRIMER
MUST BE TACKY TO THE TOUCH AND
NOT ALLOWED TO DRY WHEN APPLYING
SEALANT TO JOINT. P/G PRIMER is non-staining,
but should not be applied to exposed
surfaces, as discoloration may become apparent.
Tape joint edges if necessary.
Cleanup … Clean tools and equipment with
xylene or toluene and remove masking tape
before the sealant starts to set.
PRECAUTIONS
P/G PRIMER is a flammable product and should
be kept away from all sparks, flames, and heat.
Safety glasses and chemical-resistant gloves
should be worn at all times when mixing or
applying the primer. Apply in a well-ventilated
area. Keep out of the reach of children. Refer to
Material Safety Data Sheet for complete health
and safety information.
