Goodcrete Deep Penetrating Sealer(other names: liquid crystalline concrete waterproofing, concrete penetrating
sealer, concrete waterproofing sealer, DPS) is a water-based, inorganic, surface applied, crystalline concrete
waterproofing that especially for the waterproofing/anti-seepage/anti-corrosion etc of concrete structure. After
one time application, Deep Penetrating Sealer gives the concrete structures all-sided and permanent improvement
and protections, such as sealing, waterproofing, moisture proofing, anti-seepage, anti-efflorescence, anti-corro
sion, anti-aging etc, so, DPS is not only a kind of concrete waterproofing, but also a versatile concrete protector.
History of Deep Penetrating Sealer:
Deep Penetrating Sealer was used in the America as early as 1940s, mainly used for the waterproofing and
moisture proofing etc of underground bunkers during the Second World War, and now, it is already widely used
inso many countries for so many projects.
Functions and Benefits:
01. Easy, fast and safe to apply, labor-cost effective.
02. Permanent waterproofing, moisture-proofing, anti-seepage.
03. Excellent resistance to acid, alkali, salt and hydrostatic pressure.
04. Reduces dusting, efflorescence, cracking.
05. Self seals up to 0.3mm cracks repeatedly.
06. Reduces the damage of freeze/thaw cycle.
07. Discouraging the growth of moss and mold.
08. Anti-chloride to protect the steel re-bars from corrosion.
09. Non-toxic, approved for potable water applications
10. Can be painted, can prolong the service life of the paint/coating and concrete structure.
11. Becomes an integral part of the concrete, super resistance against high hydrostatic pressure
12. Can be applied on both dry / damp surface, new / old concrete.
13. Can be applied on either positive or negative side.
14. Doesn't need leveling layer and protective layer.
15. Doesn't form film and change the concrete's color and structure.
Working Principle:
Deep Penetrating Sealer is a silicate-based, water-soluble penetrating concrete waterproofing, after application,
which will not peel off or be scratched or worn . Unlike other sealants, which either repel water (e.g. silanes, silicones, stearates) or function as a physical barrier coating (e.g. epoxies, polyesters, vinyls), Deep Penetrating Sealer deeply penetrates into the concrete or cement mortar surface and reacts with CaOH to form C-S-H gel according to the following reaction:
As a result, the properties of concrete structure are enhanced, such as decreased permeability, increased density,
hardness and so on, overall increased the durability. The inner alkali content of the concrete is about 360 times
more than the surface's, through the pores, Deep Penetrating Sealer penetrates into the concrete structures,
chemically reacts with the free alkalis presented in the concrete and forms silicate gel, which seals the micro
racks and capillary pores becomes the integral part of the concrete, strengthens the concrete structure, and blocks
the harmful substances ingress; when water losses, it partly solidifies into crystalline powder, let the concrete
breathe freely, when meets with moisture or water, this reaction repeats again, till all the capillaries almost be
blocked, thus, gives the concrete permanent waterproofing and comprehensive protection, such as sealing,
waterproofing, moisture proofing, anti-seepage, anti-corrosion, anti-chloride, anti-aging etc.
Surface Treatment Before Using DPS:
1. Fresh concrete should be properly cured for a minimum of 7 days before Deep Penetrating Sealer is applied.
2. Thoroughly clean and remove dust, oil, contamination, coating, sealant or film to ensure the Deep Penetrating Sealer can efficiently penetrate into the surface.
Method of Using:
1. Shake well before using.
2. Apply with low-pressure sprayer, brush or roller to spray/brush/roll directly on the clean concrete surface, application temperature at 5-35℃, and relative humidity 10-90% is the best.
3. When the surface becomes semi-dry spray again.
Coverage:
About 3-5m2/kg(150-200square feet/gallon), according to the differences of temperature and porosity of the concrete, the coverage is different.
Applicable Places:
Almost can be used for all concrete constructions, whatever below and above ground, indoors and outdoors, new or old, such as,
Roads, high-ways, bridges
Various water pools or tanks
Tunnels, subways and culverts
Dams and reservoirs
Grain depot or warehouse
Ship yards, airfield runway
Air-raid shelters
Basements
Green roofs
Floor's waterproof layer
Sweating walls, foundations etc.
Limitations:
A. Not suitable for lightweight blocks, porous masonry or 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. For it is water-based liquid, so itself can't used as leaking stop/block products to stop water leaking through the crack >0.3mm, joints, or openings.
Packing: 20kg/pail, 220kg/barrel (= 5gallon/pail, 55gallon/barrel)
Storage & Shelf Life: Be stored in cool and dry place, sealed preservation, avoid direct sunligh, 10 years
