Instructions to use
Surface preparation

Blast clean to SA2½ BS7079: Part A1:1989 (ISO 8501-1:1988).

Average surface profile should be in the range of 50-75mm. Manually prepared surfaces should be to a minimum standard of St 3 BS7079: Part A1:1989 at the time of coating. Ensure surfaces to be coated are dry and free from all traces of surface contaminants.

The airless spray details given above are intended as a guide only. Fluid hose length and diameter, paint temperature and project complexity all have an effect on the choice of spray tip and operating pressure. The operating pressure should be the lowest possible consistent with satisfactory atomisation. As conditions vary, it is the applicators’ responsibility to ensure that the equipment in use has been adjusted to give optimum performance.

Conventional spray

 

Nozzle Size                       : 1.27mm (50 thou) Atomising Pressure : 2.8kg/cm² (40psi) Fluid pressure      : 0.4kg/cm² (6psi)

The conventional spray details given above are intended as a guide only. It may be found that in some circumstances, slight variations in atomising pressure, fluid pressure and alteration of tip arrangments may provide optimum atomisation.

For application by conventional spray, thinning with up to 10% Fosroc Solvent 102 may be required. Adjustment for wet film thickness should be allowed. Thinning will effect VOC compliance.

Brush and Roller

 

The material is suitable for brush and roller application.

Application of more than one coat may be required to give the equivalent dry film thickness to one spray appliced coat.

Application conditions

 

The application of Nitoprime 25 must take place immediately to a dry steel surface after completion of the preparation work. Good ventiallation is essential in conditions of high humidity,

i.e 80-85%.

Limitations

• Nitoprime 25 should not be applied when the substrate temperature is below 5°C or is 5°C and If any doubt arises concerning temperature or applicationconditions, consult the local Fosroc office..

Precautions

Health and safety

 

Nitoprime 25 and Fosroc Solvent 102 should not come in contact with skin or eyes, or be swallowed. Ensure adequate ventilation and avoid inhalation of vapours. Some people are sensitive to resins, hardeners and solvents. Wear suitable protective clothing, gloves and eye protection.

If working in confined areas, suitable respiratory equipment must be used.

The use of barrier creams provide additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. In case of skin contact with Nitoprime 25, remove immediately with resin removing cream followed by washing with soap and water.

Do not use solvent. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.

Fire

 

Nitoprime 25 and Fosroc Solvent 102 are flammable. Keep away from sources of ignition. No smoking. In the event of fire, extinguish with CO₂ or foam. Do not use a water jet.
