METHOD OF APPLICATION
Mastic compound application consist of two coats of. Primer ,Primer and followed by Mastic compound in recommended thickness, ranging from min. 12mm to 25mm in one or two layers to achieve desired thickness without any pin hole and crack.
1). Surface preparation and application of Primer: Refer application method of Primer.
2). After doing necessary surface preparation and application of primer coating, area to be installed with Mastic compound should be divided in to equal no. bays. To maintain even thickness required, place wooden or aluminum batten. Mastic compound is then broken in small pieces and put it in heating pan. While heating, keep material moving to avoid burning. It is heated until it comes in a uniform consistency and then applied on the surface and works it with wooden float, to achieve
uniform thickness and smooth surface free from any pinholes.
