Application Information
Instructions for use

Surface preparation

The substrate should be free of loose particles, dust, dirt, grease, oil or paint.

Before applying RASANTE G-15 saturate the surface with water and remove any excess water before application.

In case of fair faced concrete surface, apply a coat of DASHBOND in a thickness of 2-3 mm as a key coat to provide a mechanical key for the subsequent coat of RASANTE G-15.


To prepare the mixture, pour 13-14 Liter, of clean water into a container and add RASANTE G-15 (40kg bag) with mixing. For mixing use a slow speed mechanical mixer of 200-300 rpm.

Continue mixing till obtaining a consistence uniform mixture free from lumps.


RASANTE G-15 must be applied in a single layer of thickness up to 20mm using a smooth steel trowel or spray machine. When area has been covered to the desired thickness, lightweight leveling tools are used in conjunction with a trowel to fill in hollows. The plaster, once sufficiently stiff, should once more be given a final smoothing to remove any high points or undulations. After applying the plaster let it dry for about 30 minutes (when the plaster is setting), use a sponge float and bring the surface plaster to a cream suitable for toweling to a very smooth finish.

RASANTE G-15 does not require any curing with water, do not apply any top coat before RASANTE G-15 layer dried completely.


Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.
