Application Instructions
Substrate Preparation:
Surfaces to be coated must be brushed off and vacuum cleaned afterwards. They have to be solid to support any loads, free of sludge, dirt, oil, grease, wax, water-repellent agents and other contamination. Residual humidity in the concrete must be below 4 % according to CM-humidity measuring instrument.
In case of existing coatings, a compatibility test with the fire protection system is mandatory.
Any damage or imperfection (impact, corrosion, etc.) should be repaired prior the coating with the adequate repair mortar.
Mixing:
Stir thoroughly with slowly turning mechanical stirrer, free of lumps.
Application:
The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. In case of application by roller or brush, additional layers may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to application a trial on site may be useful to ensure the selected application method will provide the requested results.
Airless spraying:
- Material shall be applied undiluted
- Airless spray equipment with transmission ratio > 45 : 1
- Screens and filters must be removed
- Hose diameter not below ⅜ “
- Whip 1.5 - 2 m, diameter 6 may be used
- Nozzle size 0.46 - 0.61 mm (0.019 - 0.024 inch)
- Hoses must be used for water-based products only
Brushing / rolling:
- Material shall be applied undiluted
- Load natural fine bristle brushes or short pile lambswool rollers are recommended
