1. DESCRIPTION
Goodcrete Deep Penetrating Sealer(DPS) is an inorganic liquid crystalline waterproofing, it’s
colorless, odorless, environment friendly, nonflamm-
able and easy to use. The inner alkali content of
concrete is 360times more than the surface’s, through the pores, DPS penetrates
into the concrete structures, chemically reacts with the free alkali presented
in the concrete and forms silicate gel,which seals the pores and micro cracks,
blocks water and harmful substances’ ingress; when water losses, silicate gel
shrinks into active crystals and becomes the integral part of the concrete,
permanent blocks concrete structure, increases concrete density and strength, thus,
gives the concrete structures all-sided and permanent protection, such as, waterproofing/damp
roofing/anti-seepage/anti-stain/anti-corrosion/anti-aging, etc., so, DPS is not
only a kind of waterproofing, but also a concrete protective solution.

5. APPLICABLE PLACES
Almost can be used for all concrete constructions
that need waterproofing, moisture proofing, anti-seepage, whatever new or old, below
and above ground, indoors and outdoors.
But, strongly recommended for the infrastructure,
industrial and commercial buildings, such as,
Subways, Civil Air Defense, Bridges, Decks, Dams,
Tunnels, Reservoirs, Underground Passages, Plants, Warehouses, etc.
6. SURFACE PREPARATION
Freshly Finished Concrete
No treatment need, but application need after at
least 7days of the concrete casting.
Existing Concrete
1. Cracks >0.3mm, should be repaired.
2. To sweep, scrub, or strip the concrete to
remove any surface contamination or film, ensure DPS can efficiently penetrate into
the surface.
7. DIRECTION OF USING
1. Shake
well before use, do not dilute, do not mix.
2. Apply
with low/medium-pressure sprayer, brush or roller to spray/brush/roll directly
and evenly on the clean concrete surface, air temperature at 4-35℃, and relative humidity 10-90% is the best.
3. When
the surface become semi-dry after the first time spraying, proceed the second
spraying.
4. Wash the sprayers etc tools with water after the
construction completing.
Generally, the penetrating time of DPS is 1-3h,
3h or surface becomes dry after construction, the floor can walk, and after
7days can be backfilled or started following works.
Note: When rain and strong wind, can’t construct
in the open air, and avoid the surface suffer from water and rain within 24h
after construction.
Coverage
Approximately 150-200square feet/gallon, or 3-5m2/kg(2 times
spraying).
Please Note: Variations in
concrete quality, porosity, job site conditions, temperature and relative
humidity
will affect coverage rates and drying times.
8.
LIMITATIONS
A. Not suitable for lightweight blocks, porous masonry etc similar products.
B. Surfaces previously treated with curing or sealing agents, unless these coatings have completely worn off or have been removed by chemical or mechanical means.
C. Don’t use DPS to seal cracks, joints or gaps.
9.
STORAGE AND LIFE
1. Store in cool place, do not mix with other chemicals;
2. Keep this product out of the reach of children;
3. Shelf life is 10 years in the original sealed condition.
