## Description

Product Description Cracksil Wall crack filler Cracksil is a polymeric, modified powder material for filling cracks in plastered surface. It is composed of selected aggregates, polymer & additives. It has strong adhesion, is non-shrink in nature, good water resistance properties & weathering durability. Cracksil also works as a surface leveler before painting. It reduces paint consumption and increases the life of the paint, making it economical. Direction of Use Clean the surface to remove any dust, dirt, spillovers of oil, grease or loose particles. Remove the existing POP or the Putty to expose the plaster surface. Widen the crack to at least 3 mm width and moisten the crack with water. Mixing ratio of Crack Fill Powder to water varies with respect to area of application. For filling deep holes and cracks - reduce the water quantity to get a thicker pasty consistency. For surface leveling - the ratio is 2 parts of powder to 1 part of water which will yield to smooth buttery consistency. Apply cracksil in the crack with a putty blade or spatula effectively making sure that it is totally filled up. Allow it to cure.
