Water-repellent sealer (H)

Sealer (I)

Coating (C)

A water-repellent sealer penetrates – the surface is given only basic protection but remains susceptible to soiling.

A hybrid sealer (OBTEGO R-400) impregnates the surface and fills the pores.

A coating sits only on the surface – it can be scratched or peeled off.

A sealer/sealing layer sits only marginally on the surface – it can be scratched or peeled off
Surfaces
- Concrete/screeds (power-troweled, ground, polished)
- Cast stone, terrazzo
- Screeds (e.g. calcium sulfate / anhydrite, magnesite)
- Self-leveling compounds, trowel-applied compounds

| Packaging | Item no. |
|---|---|
| 9 liter plastic pail | 10200001 |
| Customs code | 32149000 |
Purpose / properties
- Once mixed with grinding dust directly on site, OBTEGO SP-100 takes on
the color of the surface concerned. - Thanks to the amount of silicates in the product, OBTEGO SP-100 integrates
very well into the substrate and stays flexible thanks to special polymers. - Subsequent grinding is therefore possible without chipping.
- OBTEGO® SP-100 is used on ground concrete floors/cement screeds that have pores and small holes after grinding.
- The product can be used to close holes 3–5 mm in size.
Function and performance
Silicates → Hardening / densification
Silicates improve scratch resistance
and reduce the absorbency of the surface.
⬇
Silicate treatment (densification) improves
mechanical properties and dust binding,
and makes surfaces easier to clean.

New silicate portfolio
With the new silicate portfolio we are completing an extensive series of research and testing at OBTEGO AG. A range of different silicate types was tested for abrasion and for the reduction of capillary water absorption (densification) on concrete floors.
Based on the results, we have further improved our silicates in terms of application and function. The new products round out our silicate portfolio to meet both our customers’ requirements and the increasing demands of the market.

OBTEGO concrete dye
A dye for coloring cementitious surfaces after installation
Purpose / properties
-
The product was developed specifically for diamond-polished concrete and is intended for interior use.
-
It penetrates deep into the surface and forms a bond with the concrete.
-
The concrete dye is part of a system together with OBTEGO silicates and sealers.
-
Applying the product evenly across the surface ensures a homogeneous appearance. The product acts as a glaze.
-
The texture and the aggregate remain visible, and there is no full coverage as there would be with an ordinary paint coating.
Colors
Golden yellow, sand, terracotta, orange, red, turquoise, blue, green, brown, gray and black.
Application and possible uses
Main products/systems used:
- R-30 → basic protection requirements; logistics areas
- R-40 → color & protection for a homogeneous surface
- R-400 → premium protection, for example for terrazzo surfaces
- P3/R-30 + R-400 → complete systems for industrial floors
- P-3 + R-405 → complete systems for industrial floors (water-dilutable)
- P-10 + R-400 → highly absorbent floors (screed, self-leveling compounds)

Diamond cleaning stage (surface preparation – optional)
Removal of efflorescence, marks from plastic coverings and heavy soiling. Important for a better appearance, homogeneity and higher gloss. Diamond grinding technology, for example with grit # 100 (dry) or # 200 (wet).

Measurement
Removal of dust, heavy soiling and slight efflorescence. Hard cleaning pad or diamond cleaning pad. Clean small areas with a single-disc machine and a wet vacuum. Larger areas with an automatic scrubber-dryer.

Measurement
Residual surface moisture should be < 6 % Tramex or < 4 CM %.
Excessive moisture can lead to cloudy marks on the surface. With three-component concrete systems there is a greater chance of efflorescence.

Pre-treatment/primer (optional)
Apply the silicate/densifier or primer by spraying and with a nylon roller or mop. On absorbent surfaces two applications are required. Allow the silicate/densifier or primer to dry completely.

Surface treatment
Apply the products evenly and homogeneously to the dry surface using a pump sprayer. On surfaces with higher absorbency, several applications will be needed until the surface is saturated.

Surface treatment (colored)
Spread the product using the classic cross-roller application method, or apply it with airless equipment and smooth it out with a roller.

Polishing (optional)
For R-400 application only: before the material starts to dry, use a single-disc machine and a white polishing pad to obtain a uniform finish. Avoid splashing the material. On larger areas, twin power trowels with white pads are used.

Curing time
Depending on temperature, humidity and site conditions; ready to walk on after 7–15 hours. Ready for service after 24, preferably 48 hours.

Statement to the customer
Competition
- No equivalent products to OBTEGO R-30, R-400 and R-405 are currently known → unique selling point = hybrid sealer.
- Competing products in Europe: Ashford Formula, Pentra-Sil + Pentra Guard, C2 Hard + C2 Seal
- Two-layer hardening + protection systems (for example Pentra-Sil + Pentra-Guard) make a good impression immediately after application when new, but after a few weeks or months the protective layer is worn away, because it is only superficial (a thin polymer film). Visible burn marks and unwanted migration of plasticizer components are further problems with these polymer protective agents.
Market pricing
- With OBTEGO products/systems there should be no great price difference compared with the competitors listed above (chemical cost per m² only). Depending on discounts, the protection system and the absorbency of the floor, between EUR 0.50 and 3.00/m²
- Differences across the whole floor concept and depending on surface preparation (cleaning only, diamond cleaning, or several grinding and polishing steps) between EUR 2.00 and 25/m². Also depending on the size of the area and the labor involved.
Limitations / conditional application
- Wet rooms such as showers or public restrooms / urinals (a PU coating is probably a better choice)
- Areas where larger amounts of fruit acids may reach the floor (for example retail areas: wine racks, vinegar, fruit, etc.). If acid is left on the floor for a longer period, slight surface etch marks may — but need not — occur.
- Industrial areas where acidic or strongly alkaline cleaners are used (for example meat processing and other fresh-food operations). In these cases, too, consider PU coatings instead.
- On electrostatic discharge (ESD) floors, a sample must be applied first. Generally there is no significant change in conductivity, but humidity in the building and other conditions may have some influence.
