تجهيز السطح
The substrate must be structurally sound, clean and free from dust, oil, grease, old coatings, curing compounds and any foreign materials that may reduce adhesion.
Use suitable mechanical preparation methods such as grinding, sandblasting, grit blasting or another approved method to remove existing coatings and surface treatments.
Repair all cracks, spalled concrete and defective areas using a suitable WHITE SAND concrete repair system.
Repair blowholes, pinholes and minor surface imperfections using WHITE SAND EPF 50 epoxy putty.
Steel substrates must be grit-blasted to remove rust, mill scale and contamination, followed by the application of a compatible primer where required.
تطبيق البرايمر
EP 150 is formulated for self-priming application on suitable, correctly prepared substrates.
For highly porous concrete, apply WHITE SAND PRIME EP 100 epoxy primer before applying EP 150.
الخلط
- Ensure that the substrate, tools and application equipment are ready before mixing because the product has a limited pot life.
- يجب خلط العبوات الكاملة محددة النسب مسبقًا من المصنع فقط.
- Pour the entire contents of the hardener component into the base component.
- Mix using a slow-speed electric mixer fitted with a suitable mixing paddle.
- Continue mixing for approximately 2-3 minutes until completely homogeneous.
- Avoid introducing excessive air into the mixture.
- Scrape the sides and bottom of the container at least once during mixing.
- Continue mixing until the color and consistency are completely uniform.
- Do not divide the packs or alter the factory-proportioned mixing ratio.
طريقة التطبيق
- Apply the mixed EP 150 uniformly to the prepared substrate.
- Use a short-nap mohair roller, suitable brush or airless-spray equipment.
- Apply each coat at a recommended dry-film thickness of approximately 200 microns.
- Ensure uniform coverage without pinholes, missed areas, ponding or excessive material build-up.
- Apply two coats to achieve a total recommended thickness of approximately 400 microns.
- Allow the first coat to dry before applying the second coat.
- Apply the second coat within the stated recoating interval of 8-24 hours at 23°C.
- Provide adequate ventilation to support proper drying and curing.
- Protect the coating from water, chemicals, contamination and mechanical damage until fully cured.
- Allow at least seven days at 23°C before placing the coating into full service.
معدل التغطية والاستهلاك
The TDS states an approximate coverage of 5 m²/kg per coat at a film thickness of approximately 200 microns.
The stated coverage is approximate and must be confirmed by a site trial. Actual consumption depends on substrate porosity, surface profile, application method, film thickness and material wastage.
التنظيف
Clean tools and mixing equipment using WHITE SAND SOLV 10 before the material hardens. Fully cured material can only be removed mechanically.
التخزين ومدة الصلاحية
The components of EP 150 have a minimum shelf life of 12 months when stored in unopened and undamaged original packaging under dry warehouse conditions.
قد يؤدي التخزين في درجات حرارة مرتفعة أو مستويات رطوبة عالية إلى تقليل مدة صلاحية المنتج.
