.DESCRIPTION AND USES .
OKON PLUGGER is water base, low VOC, acrylic micro-
emulsion specifically designed to protect both new and
existing porous concrete surfaces. The special blend of
acrylic resin and water repellent additives provides
multiple benefits especially important when protecting very
porous CMU.
 The acrylic resin reduces the pore size of the substrate
thereby reducing the capillary action that draws water
into the substrate.
 The proprietary water repellent lowers the surface
tensions and further counteracts the capillary pull.

.PRODUCT APPLICATION .
SURFACE PREPARATION
OKON PLUGGER can be applied to most porous concrete
surfaces that are unsealed, clean (free of dirt, waxes and
oils) and sound. New concrete must be cured for 28 days
prior to coating.
Unsealed: PLUGGER must be able to penetrate surface.
Test the openness of the substrate by sprinkling with
water. If the surface turns dark with the water PLUGGER
can be applied.
Clean: Clean surface using oil-free, compressed air to
remove loose and foreign matter that could interfere with
application or performance of coating. Pressure wash
surface to remove dust, sand or other foreign matter.
Allow pressure washed surfaces to dry three days prior to
coating. Remove exterior mildew with JOMAX
®
or
equivalent. Remove efflorescence with sulfamic or dilute
muriatic acid. Spot cleaning with acid may cause uneven
porosity and blotchy appearance. Rinse the surface
thoroughly after chemical cleaning. Un-rinsed acid salts
may cause whitish-blotches to appear. Surface can be
slightly damp at time of application

SURFACE PREPARATION (cont.)
Sound: Surface of concrete and mortar joints must be
hard and firm - not loose or sandy. The surface is un-
sound if it can be scraped or gouged with a flat
screwdriver. Unsound mortar or deteriorated concrete
should be removed and repaired prior to coating. Cracks
and joints must be sealed with flexible sealant. Parapet
walls must be capped and the backside sealed with a
waterproofing membrane.
COVERAGE
The rate of application will vary depending on:
A. The weight of the block – A minimum of two coats are
Required to adequately seal lightweight and some
medium weight block.
B. The block mix - Integral ad-mixtures like W.R. Grace
Dry-Block®, help the block drain and are required in
Light-weight block to receive a 5-year Warranty.
C. The total surface area to be covered is greatly affected
by the face-style and mortar joints of the block. Split
face block has approximately 30% more surface area
than smooth block and fluted block can have two to
four times more surface area than the two-dimensional
surface area.
APPLICATION
PLUGGER is best applied by airless spray. Use a small to
medium size airless pump (⅓-⅔ gpm) at 500 psi and a
0.031”- 0.035” tip. Protect adjacent and underlying
surfaces from over spray and rundown. The surface
temperature at time of application and for four hours after
application is very important. Application to cold (<50°F) or
to hot surfaces (>100°F) will reduce the durability of the
material. Surfaces temperatures >100° F can be cooled by
misting with water immediately prior to application.
PLUGGER can be applied to damp but not wet surfaces.
The surface is wet if moisture transfers to your hand when
you touch it or if it glistens in appearance.
Vertical Surfaces: Apply from bottom of wall up using low
pressure airless spray. Flood the surface until material
runs down 6 to 8 inches below spray pattern before being
absorbed. Pick up runs or drips with a dry roller or brush.
Overlap spray pattern to avoid holidays.
Horizontal Surfaces: PLUGGER should not be used on
horizontal traffic areas. Horizontal surfaces like window
sills or railings must be sloped for drainage. Flood the
surface with sufficient material so the surface remains wet
for several minutes before material is absorbed. If surface
pooling or puddling appears, back-roll, brush, wipe up, or
broom away excess material.
Recoat: PLUGGER can be recoated after the initial coat is
dry, clear and colorless.
