Application Instructions

Pre-Treatment:

Prior application of Pyroplast Top WB, the surface to be coated must be dry, clean and free from dirt, oil, grease or any other contamination.

Stir thoroughly, ensuring product is 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.

Brushing or Rolling:

• Material shall be applied undiluted
• Load natural fine bristle brushes or short pile lambswool rollers are recommended

Airless Spraying:

• Material shall be applied undiluted
• Airless spray equipment with transmission ≥ 30 : 1, pressure approx. 180 bar
• Whip line ¼ " may be used
• Nozzle size 0.28 - 0.38 mm (0.011 - 0.015 inch)
• Hoses must be used for water-based products only

Above data shall be used as a guideline with variations being made to suit local conditions. Clean equipment immediately after use with water.
