Nitomortar PEFM 6103Nitomortar PECI/SfB: (4-) Pr4December 1999High strength jointing and multi-purposerepair compoundsUsesFor fast and emergency reinstatement of concrete, bedding,jointing and reprofiling of concrete, masonry and brickwork.Nitomortar PE is ideally suited for the repair and reprofilingof precast concrete units, damaged arrises and treads. It canbe used to infill hollows and holes in concrete floors,bedding and fixing kerbstones, manhole sets, frames, brickslips, ceramic tiles, slabs and coping stones. Nitomortar PEConcrete should be used to repair larger voids. Theproducts are especially useful where fast strength gain isimportant. When properly compacted, they are highlyimpermeable.Advantages■ Fast development of strength minimises disruption —stronger than concrete within 2 hours■ No primer required■ High chemical and oil resistance■ Extremely versatile — can be poured, trowelled ormodified with aggregate without significantly affectingsetting times or strengths■ Extremely low wastage due to ability to mix part packs toconsistencies required■ Will cure down to 0°C■ Pre-weighed components ensure consistencyDescriptionNitomortar PE products are based on a polyester resinsystem. There are two grades.Nitomortar PE: The standard material for general purposeuse.Design criteriaThe following guidelines should be used.Nitomortar PEMaximum thickness: 12 mm 40 mmMinimum thickness: 5 mm 5 mm*Nitomortar PEConcreteMaximum plan area: 0.25 m² 0.50 m²Maximum linear run: 1 metre 1 metreGreater thicknesses should be built up in layers and largerareas should be applied in a ‘chequerboard’ fashion.Consult the local Fosroc office for further information.* Note: When using aggregate larger than a sand grading,the minimum thickness will be increased. Consult the localFosroc office for further information.PropertiesGeneralBond strength: Nitomortar PE forms a strong bond tomost structural materials provided the surfaces are dryand suitably prepared. The resulting bond betweenNitomortar PE and concrete will be stronger than the tensilestrength of the concrete itself.Shrinkage: The polyester resin used in Nitomortar PE isformulated to reduce shrinkage to a minimum. Linearshrinkage will be approximately 0.8%. No further shrinkagewill occur after the material has cured.Durability: Cured Nitomortar PE performs undertemperatures as high as 60°C and down to sub-zeroconditions.Nitomortar PE CI/SfB: (4-) Pr4 December 1999Nitomortar PE Concrete: A special grade allowing users toadd suitable aggregate, thereby substantially reducing thecost of infilling larger voids.Winter versions of Nitomortar PE is available which arefaster setting at low ambient temperatures. Both grades ofNitomortar PE are supplied as two-component productswith pre-weighed quantities of liquid resin and powderedhardener, ready for on-site mixing and use. The hardenersystem enables the mix to be varied from a pourableconsistency to a trowellable mortar without significantlyaffecting the setting times or strengths achieved.Chemical resistance: Fully cured Nitomortar PE isunaffected by water, petrol, oil and many corrosivechemicals. It is not recommended for use in contact withketones, phenols, strong alkalis and oxidising agents.Because chemical resistance can be affected by externalvariable factors (e.g. temperature), the local Fosroc officeshould be consulted for specific applications.Underwater use: Nitomortar PE will cure under water. Thelocal Fosroc office should be consulted when consideringthis type of application.92

Ifworking in confined areas, suitable respiratory protectiveequipment must be used. In case of contact with eyes, rinseimmediately with plenty of clean water and seek medicaladvice. In case of skin contact, remove immediately withresin removing cream followed by washing with soap andwater. Do not use solvent. In case of contact with eyes, rinseimmediately with plenty of clean water and seek medicaladvice. If swallowed, seek medical attention immediately —do not induce vomiting.FireNitomortar PE products are flammable. Keep away fromsources of ignition. No Smoking. In the event of fire,extinguish with CO 2or foam.
