Deep Penetrating Sealer (DPS) – One Gallon


Creto DPS is a PERMANENT, ONE TIME water based internal membrane forming application sealant that completely waterproofs, strengthens, cures, dust-proofs, and preserves most cement-type surfaces.


What is Creto DPS?

Creto DPS is a PERMANENT, ONE TIME APPLICATION, water based, internal membrane forming sealant that completely waterproofs, strengthens, cures, dust proofs, and preserves concrete substrates. By penetrating deep and reacting with the free lime and alkali present in concrete, Creto DPS solidifies the concrete into a solid, non-porous mass. This creates a permanent internal seal that BECOMES PART OF THE CONCRETE, not just a surface coating. Creto DPS protects without changing the color or texture of the surface. Creto DPS is not a surface sealer. Creto DPS effectively starts working as a sealer about 2 to 3 mm below the surface. However, Creto DPS is much more than just your regular concrete sealer. Creto DPS contains a proprietary catalyst which causes a chain reaction to start:

-It allows DPS to penetrate below the surface of the concrete or alkali bearing substrate where it pursues moisture down through the substrate.
-Upon contact with the free alkali (lime) and calcium hydroxides (in that moisture) it reacts instantly to form a silica gel membrane on the (moist) surfaces of all the voids and particulate, (sand, aggregate and cement) immediately waterproofing the substrate.
-Over time, this silica gel membrane hydrates and hardens into a solid, yet, breathing, glass impregnated mass which provides a permanent seal and moisture barrier, as well as increased surface hardness/dusting resistance and compressive and flexural strengths.

What are the benefits of Creto DPS?

  • A one time application and permanent solution

  • Holds back Hydrostatic Pressure
  • Lowering the ph level at the concrete surface for greater adhesion of topical coating.
  • Retards penetration of grease, oils, and acids
  • Reduces or eliminates wear due to abrasion, freeze-thaw and salt attack
  • Reduces or eliminates bacteria growth
  • Protects against ASR (Alkali-silica reaction)
  • Non-Flammable
  • Stabilizes concrete substrate
  • Reduces or eliminates sweating
  • Enables easier ice and snow removal
  • Increases bonding of any top coating 300%
  • Cures new concrete uniformly

Deep Penetrating Sealer Application Instructions

The “A, B, C’s” of Applying DPS

A.: Application Procedures for Low Moisture Content and Low Hydrostatic Pressure:

Surface Conditions: DPS can be applied to dry surfaces, but, is best applied to damp surfaces. Ensure there is no standing or running water on the surface to be treated.

Be aware of surface temperature. If the concrete or substrate is too warm, (I.e. warm to the touch), evaporation will reduce the amount of DPS available to penetrate through the slab. To ensure a minimum of product lost to evaporation, pre-wet or soak the area to be treated with water, spread out or mop up any puddles, and proceed with the DPS application when the surface has dried to the “damp” stage.

Application: Apply DPS liberally (at minimum the predetermined coverage rate) and saturate all areas. Each spray swath should over lap the previous one by half it’s width. To ensure saturation, check areas 15 to 20 minutes after application because porosity will vary (over the area being treated) and some areas will appear to be drying faster.

The recommended procedure is; as soon as the entire area has been covered, go back and go over those areas that are most absorbent and drying fastest, again, at the same speed or rate of spraying.

Do not leave puddles of DPS. Use a mop or squeegee to remove any puddles.

Applying water over a DPS application will push the DPS deeper.

It is recommended the water be applied no sooner than when the surface treated with the DPS is no longer wet, but, not yet dry. I.e. Damp.

Testing for number of coats of DPS required & Multiple Coat Applications Procedures:

Sixteen (16) to 24 hours after the first DPS application the surface should be thoroughly flushed with clean water, to remove any alkali or contaminants the DPS pushes to the surface.

Allow surface to dry.

To determine whether a second application of DPS is necessary; Tape down several pieces of ordinary, dry sponge or foam rubber, to the slab. Leave for 24 hours, then remove. If, the slab beneath them or the sponge itself, is wet, the slab requires another application of DPS.

The DPS for this second application should be applied to saturation again, checking for areas of varying porosity, but, not leaving any puddles. Wait 16 to 24 hours.

Any alkali or leaching which occurs after the second treatment must be flushed off and the slab cleaned thoroughly (and allowed to dry) prior to a re-testing with sponges (if required) to determine the need for any further application of DPS.

Note: Steps or areas which have been salted over many years, is a good example of a substrate with an extraordinary contaminant content.

In such cases the process of flushing (after applying DPS) to ensure all salts, alkali or contaminants have been pushed to the surface and removed, could involve cycles of daily flushing and drying for 3 to 7 days before no further contaminant appears after drying.

Once the rinsing is no longer flushing anything to the surface, and no further application of DPS is required, the treated and flushed surface should be allowed to thoroughly dry for a minimum 24 hours prior to the application of any secondary coatings.

On vertical, formed surfaces; Apply DPS as soon as the forms have been stripped and the surface rubbed, (if required). Apply from the bottom up, going over the area twice to ensure saturation. One such application (to saturation) will usually be sufficient for most requirements.

Back-filling foundations may take place 12 hours after application. Foot traffic is permissible in most cases within 3 hours or when surface appears dry.

On overhead surfaces, DPS is best applied with a sprayer using multiple light applications as required.

The first application should wet the surface. Do not saturate as dripping will occur.

B. Application Procedures for High to Extreme Moisture Content or Hydrostatic Pressure Situations: I.e. Wall or substrate is either wet or water is visibly seeping through crack/hole.

  1. 1. Crack is less than 3mm. /1/10 in.In width, and water is weeping:
    1. Thoroughly wet surface area with DPS, and immediately after wetting with DPS, dry Portland powder should be hand rubbed (using latex gloves) into the cracks.
  2. Wet treated surface again with DPS, wait 10 minutes, “dust” surface with dry Portland powder again, then apply a third coat of DPS.
  3. Crack (or hole) is greater than 3mm. /1/10 in. in width And water is flowing at less than 1 gallon per hour:
    1. Thoroughly wet area, cracks and/or holes with DPS.
    2. Fill cracks and/or holes with moist mixture of Portland based patching cement, (1 part water to 3-4 parts sand mix, or equivalent) using 1 part water and I part DPS to achieve normal consistency of cement. This mixture should remain workable for 15 minutes.
    3. If necessary, push the mixture into the cracks or holes by hand, (using latex gloves),
    4. After the mixture is in the crack/hole smooth the surface, first with trowel, then with a soft paint brush dampened with water.
    5. Wet treated surface again with DPS, wait 10 minutes, then “dust” surface with dry Portland powder and then apply a third coat of DPS.
    6. Wait 20 minutes, then “dust” surface with dry Portland powder and then apply a fourth coat of DPS.
  4. Crack or hole is greater than 3mm/ 1/10 in. and water is flowing at greater than 1 gallon per hour:

Repeat the 6 steps, a) through f) above, except an epoxy coated wire screen may be inserted between applications of the patching mixture.

For very heavy flow rates, be sure the water/DPS to cement ratio is not greater than 50% (1:1), and not less than 32% (1:2). While, generally, the lower the water/cement ratio, the greater the strength of the concrete, in order to completely fill the crack/hole as far down as possible, sometimes a slightly wetter mix is required.

C. Precautions

DO NOT ALLOW DPS TO COME IN CONTACT WITH GLASS OR ALUMINIUM OR GLAZED TILE, ETCHING WILL OCCOR! (If contact does occur rinse immediately with water and wipe dry with a clean cloth.)

Do not apply DPS if the concrete surface temperature is below 45° or if the air temperature is expected to drop to freezing during the day or overnight. DPS will need 24 hours of cure time before temperatures can drop to freezing or below.
