Remove all loose materials or traces of foreign materials and ensure surface cleaned, free of dust and dirt. It is recommended to damp the substrate surface prior to the application of POLYMiX Fine Mortar Base Premium.
Mix thoroughly a bag of 25kg POLYMiX Fine Mortar Base Premium with 7.0 – 8.0 litres of clean water by using an electrical power mixer for 3 to 5 minutes until the homogeneous paste is achieved. Re-mix the material before re-use if the material is left undisturbed for more than 30 minutes.
Apply freshly mixed POLYMiX Fine Mortar Base Premium with steel trowel or spray machine to profile the substrate surface to an average thickness of 2 to 4mm. If application requires more than a single coat, continue to trowel POLYMiX Fine Mortar Base Premium and to allow the underlying coat to gain partial curing before applying the subsequent coat to achieve the desired flatness. POLYMiX Plaster Finish can be then applied onto POLYMiX Fine Mortar Base Premium if extra smooth finishing is required.
