Substrate

Properties/tests

• The substrate must be dry, solid, clean, dust-free, absorbent, load-bearing and free of separating agents, corrosive components or other layers that could interfere with the bond.
• In principle, the substrate must be suitable for the coating system.
• The adhesive tensile strength of the substrate must be at least 1.5 N/mm².
• The moisture content of the zone near the surface (approx. 3.0 cm) must not exceed the equilibrium moisture content of the building materials. Concrete and cement screed: < 6.0 CM%, anhydrite screeds: < 0.5 CM%.
• The substrate must be protected against rising and penetrating moisture.
• The compressive strength of the substrate should be at least 25 N/mm².

Pretreatment

• The floor surface must be prepared by e.g. dust-free shot blasting, diamond grinding, milling or other suitable measures. The grain structure must be exposed and all separating substances and loose components must be removed thoroughly. Substrates whose surfaces have been treated with smoothing agents (waxes) must always be removed by milling and subsequent shot blasting.
• Compatibility with old coatings must be checked, non-load-bearing layers and coatings must be completely removed.
• Asphalt-containing screeds are difficult substrates due to their deformability under mechanical and thermal stress. They can therefore only be coated with special systems. Please contact our technical service for more information.
• In the case of existing fixed tile coverings, the surface must be removed by diamond grinding or milling. The glaze must be completely removed.

Processing

Mixing / Preparation / Processing

• The hardener component is completely added to the resin component. The components are mixed homogeneously using a slow-speed agitator (approx. 400 rpm with stirring paddle). The mixing time is 2 minutes. Ensure that no excessive air is stirred into the material. After homogeneous mixing, the material is poured into a clean container and mixed again for 1 minute.

Processing

• HADALAN Pripor 12E is applied to the surface immediately after mixing and spread evenly with a rubber squeegee. The material is then leveled with a short-pile epoxy resin roller or loop roller.
• The material consumption depends heavily on the condition of the substrate. A 2-layer application is recommended for very porous substrates. The spreading interval between the two coats and subsequent leveling coats must be < 24 hours.
• Alternatively, the material can be applied using a powerful airless device. Airless nozzle approx. 521.

Cleaning the tools

• Clean tools and equipment immediately after use.
• Hardened material can only be removed mechanically.

Notes

• Maintain a processing temperature of +8 °C to +25 °C.
• The application distances for multi-layer coatings must be observed.
• High temperatures accelerate, low temperatures delay the solidification and curing process.
• Epoxy resins are not permanently color stable.
• Pour the material out of the container immediately after mixing.
• Color deviations on contiguous surfaces do not constitute a defect.
• For machine application, carry out preliminary tests.
• To ensure a non-porous substrate, the specified consumption quantities must be observed.
