Special colours available on request.
Any discolouration that occurs does not have a negative impact on the technical properties of the material. Organic dyes (e.g. in coffee, red wine or leaves) as well as various chemicals (e.g. disinfectants, acids, etc.) can lead to colour changes. Abrasive strain may cause scratches in the surface. The functionality is not affected by this.

Suitable Substrates
Concrete and cement screed and hard asphalt screeds indoor
The substrate must be dry, load-bearing, dimensionally stable, solid, free from loose parts, dust, oils, grease, rubber abrasion and other separating substances. Cement-based, polymerenhanced levelling compounds must be checked for their coatability and, if necessary, test surfaces must be applied. The compressive strength of the substrate must be > 25 N/mm2.
The average surface tensile strength of the substrate must be 1.5 N/mm2. The smallest single value must not be below 1.0 N/mm2. The substrates must have reached their equilibrium moisture content:
Concrete and cement screed: max. 4% by weight (CM method)
Test methods for the specified values must be in accordance with the Restoration
Guidelines, Part 3 set out by the German Committee for Structural Concrete (DAfStb).
If moisture from the rear is expected, a non-porous priming coat must be applied with DisboXID 420 or DisboxXID 462. In this case, the average surface tensile strength of the substrate must be 2.0 N/mm2. The smallest single value must not be below 1.5 N/mm2.
Hard asphalt screeds must comply with hardness class IC 10 or IC 15 and must not deform under the given temperature conditions and mechanical loads.
Separate advice must be provided by Disbon for other types of substrates and procedures.
Substrate Preparation
The existing substrate is prepared with low-dust blasting using abrasive material (shot blasting) and simultaneous dust extraction. The level of low strength layers that are removed is dependent on the pressure and the type and quantity of the abrasive material. Grinding is only permissible on smaller surfaces (edge processing) with the exception of diamond grinding to prepare surfaces and remove low strength layers.
Furthermore, BEB worksheet KH-0/U✱, BEB worksheet KH 3✱ and Table 2.5 of the Restoration Guidelines, Part 2 set out by the German Committee for Structural Concrete (DAfStb) must be observed.
Old, rigid two-component coatings must be cleaned thoroughly and then ground or matt blasted (until the stress whitening is visible), so that no residual materials, care products or similar remain on the surface being coated.
Fill broken-out and void areas in the substrate with DisboCRET®-PCC Mörtel or DisboXID EP Mörtel to achieve a flush surface.
For hard asphalt screed, at least 75% of the admixture must be visible after preparation.
Do not use silicone-based materials in the surrounding area before or after the coating measures as they can cause surface defects.

Preparation of Material
Mix comp. A (base compound), add comp. B (hardener) for the base compound and mix thoroughly with a slow-running agitator (max. 400 rpm) until a streak-free and uniform colour is achieved. Transfer the material to another container and mix again thoroughly (do not use the delivery container).
Mixing Ratio
Comp. A (base compound) : Comp. B (hardener) = 82:18 parts by weightMethod of Application
Depending on the application, use a smoothing trowel or suitable scraper (e.g. hard rubber toothed squeegee). Use medium pile roller on spread surfaces to maintain the rough surface.| Note: In the case of application with a toothed squeegee, the selected triangular toothing does not automatically lead to compliance with the specified consumption values. |
Surface Coating System
Priming coat1. Prime mineral substrates with DisboXID 462 two-component EP primer to fill the pores. Rough substrates should also be levelled with a scratch filling (primer mixed with quartz sand). Depending on the requirements,
DisboXID 2K-EP-Grundierung Premium, DisboXID 460 2K-EP-Grundierung,
DisboXID 461 2K-EP-Grundierung, vorgefüllt
can be used as an alternative. Detailed information can be found in the respective TI.
2. Indoor hard asphalt surfaces must be primed free of pores using DisboPUR 374 with a smooth hard rubber slider or scraper. Rough, porous asphalt substrates can be levelled off with an additional scratch filling
DisboPUR 374: 1 part by weight,
DisboADD 942 Quartzsandmischung ( 0.1-0.4 mm): 0.5 parts by weight.
Top coat
Flow coating
Pour DisboPUR 374 onto the primer and spread evenly with a hard rubber toothed squeegee. After a waiting period of approx. 10 minutes, deaerate the fresh coat with the spiked roller.
Levelling mortar
After transferring the material to another container, stir and add approx. 50% by weight of DisboADD 942 or DisboADD 941 Quartzsandmischung (0.06-0.3 mm). Pour the produced levelling mortar on to the priming coat within the processing time and handle in the same way as the flow coating.
| Note: If special colours are used, the maximum possible amount of sand, that can be added, must be checked as it may be less than 50% by weight depending on the colour. |
To ensure the surface is matter and increase anti-slip properties, approx. 20 g/m2 DisboADD 955 Mattierungsmittel can be blown into the fresh coating with a hopper gun.
Interspersion coat
After transferring the material to another container, stir and add approx. 50% by weight of DisboADD 942. Pour the produced levelling mortar onto the primer as an interspersion layer and spread evenly with a hard rubber toothed squeegee or a smooth, hard rubber scraper. Then sprinkle the fresh interspersion layer fully with DisboADD 943 Quartzsandmischung (0.4-0.8 mm) or DisboADD 944 Quartzsandmischung (0.7-1.2 mm). Once the interspersion layer has set, brush off any excess quartz sand. Pour DisboPUR 374 onto the interspersion layer and spread evenly with a hard rubber scraper and a medium pile roller.

✱ This is a recommendation. The notch size depends on the wear resistance of the scraper, the temperature, filling level and unevenness of the ground.
The consumption of the top sealing coat on spread coatings varies due to temperature influences, type of application, tools and different spreading materials. Exact consumption values should therefore be determined by applying a sample to the object.
Workability
Approx. 25 minutes at 20°C and 60% relative humidity.Higher temperatures shorten the pot life, lower temperatures extend it.
Application Conditions
Material, circulating air and substrate temperature:Min. 5°C, max. 30°C
The relative humidity must not exceed 80%. The substrate temperature must always be at least 3 C above the dew point temperature.
Waiting Time
The waiting times between work cycles must be at least 16 hours at 20°C and a maximum of 24 hours. For longer waiting times, the surface of the previous work cycle must be sanded if it has not already been sanded off.
The specified period is shortened by higher temperatures and extended by lower temperatures.
Drying/Drying Time
At 20°C and 60% relative humidity, can be walked on after approx. 16 hours, mechanically durable after approx. 3 days, fully cured after approx. 7 days.
Correspondingly longer at low temperatures. Protect the applied material from moisture during the curing process (approx 16 hours at 20°C), as otherwise surface defects and reduced adhesion may occur.
Tool Cleaning
Immediately after use and in case of relatively long breaks in work, using DisboADD 499 Verdünner/Reiniger.German Certificates
