Application Procedure:
Repairing cracks
Small cracks in plaster should first be widened so that filler can be pushed right in. The corner of a scraper or filling knife is ideal for removing any loose plaster and for opening up and deepening the crack. Try to undercut the crack with the corner of the scraper to give a better key for the filler. For a hard cement-sand base plasters/Concrete joints/cracks, mechanical tools can be used to widen the crack and make a “V” notch.
To Use a dry paint brush along the line of the crack to remove any loose dust and dirt. Pre-wetting is also required before application of Crack Fill Material.
Mix Crack fill material with 27 -32% of water ( by weight) . With Mechanical stirrer relatively more homogeneous mix is obtained and also it can keep the water content to the minimum.
Before applying it, dampen (but don’t soak) the inside of the crack using a small paint brush dipped in clean water.
Use a filling knife to apply the filler along the line of the crack and press the filler into it
Dip a clean filling knife in clean water and run it along the line of the crack to level the filler to the surface around it.
If there is debonding of plaster from block/brick/concrete/joints, the relevant patch work has be done by removing loose/de-bonded plaster (prior to the application of application of Crack fill).
