Versatile, Compatible with all common hydraulic cements. Cost effective, Nitobond sbr latex is economical tousedescriptionnitobond sbr latex is modified styrene butadiene emulsionpurpose-built for serve as a bonding aid and gauging liquidfor cementitious systems you will find it to be resistant to hydrolysis and cantherefore can serve as a tool for external applications too. Technical supportfosroc offers expert technical guidance service supported by ateam of specialists withacross the field. Propertiestypical mechanical properties of 1 3 cement sand mortar atw/c, 0. 45 for control and w/c, 0. 35 for mortar containingnitobond sbr latex 5 lites / 50 kg cement . Tested inaccordance with bs 6319 & wet cured. Note increased dosages of nitobond sbr latex andfurther water reduction leads to improved mechanicalproperties. Chemical resistance cementitious based materials have limited chemicalresitance. The incorporation of nitobond sbr latex to cementmortars reduces permeability and therefore helps reduce therate of attack by aggressive chemicals. Application instructionssurface preparation the object of the surface preparation is to achieve a cleansound surface with a good mechanical key. All substratesshould be cleaned and lacking in dust, Plaster, Oil, Paint, Grease, Along with, Corrosion deposits any additional deleterious substances. Laitence should is eligible for removal by mechanical means. Smoothsubstrates must be mechanically roughened needle gun, E. G. Byscabbling or grit blasting to supply an adequatekey. Corroded reinforcing steel should be exposed around its fullcircumference and cleaned to remove all loose scale andcorrosion deposits. This product represents always preferably to clean the steelto a bright condition. Use of emery cloth, Grit or sand blastingis recommended. Primingreinforcing steel must be primed with nitozinc primerimmediately after cleaning. The concrete substrate should bethoroughly dampened with water and any excess removedbefore being primed by thoroughly scrubbing in a slurry coat of1 volume nitbond sbr latex to 1 volume water to 3 volumesfresh cement. To achieve obtain a smooth consistency the cement shouldbe blended slowly into the liquids. Stir frequently during useto offset settlement. Avoid puddling of the slurry coat. The topping must be appliedon to the wet slurry. If the slurry dries out it must be removedand the clean substrate reprimed. Typical mix designs 1.
