|BRAND||PERMA CONSTRUCTION CHEMICALS|
Perma Crack fill is a specially formulated polymer modified repair mortar designed to fully meet the requirement of effectively filling cracks in plasters and in concrete, avoiding the use of costly sealants. Perma Crackfill is a dry powder when mixed with water it forms a creamy consistency paste which is ready for use in filling cracks and repairing plasters.ADVANTAGES
Perma Crackfill replaces costly sealant and putties. It is non shrink, hence possibility of shrinkage cracks are non existant. It has high tensile strength and good adhesion property. The finish achieved is sufficiently smooth. Good resistance to freeze / thaw cycles, carbonation and attack by chlorides. Conventional curing is not required. DIRECTIONS FOR USE
Preparation: It is essential that the surface of the concrete to be repaired is sound, clean and uncontaminated. Chase the crack and form a neat "V" shaped groove at least 6 mm wide on surface. Damaged plasters can be cut out in more or less square sides. Defective material must be removed carefully using reducing tools, needle guns or sharp tools and chipping hammers. Force must not be applied as it will damage the sound material beneath. COMPOSITION
Perma Crackfill is a whitish grey coloured powder, a blend of special cement, polymer additives and selected graded fine aggregates. The same when mixed with water results in a whitish grey workable paste which can be trowelled to a fine finish.MIXING
Just add water to Perma Crackfill by volume in the ratio of 1 water to 4 volumes of powder and mix thoroughly to get an even consistency mortar. In demanding situations Perma Bond PVA can be used to replace water and the same can be used for priming the surfaces before application of Perma Crackfill. Whereas, well mixing by trowel is suitable for small mixes, it is recommended that an efficient mechanical mixer be used.
