HEALTH & SAFETY
NCL CEMPROOF 4 contains cement which is highly alkaline and may cause irritation of the skin. Operators are advised to wear
protective clothing and gloves during use. Mixing should be carried out in a well ventilated area and in common with all powder
products in order to avoid raising and inhaling of dust. If the powder enters the eye, wash thoroughly with copious amounts of
fresh clean water. If discomfort continues, please seek for medical advice.
METHOD STATEMENT
PREPARATION
• Surfaces to be applied with NCL CEMPROOF 4 should be sound, clean and free from all dirt, loose particles, paint films,
protective coatings, oil and grease, laitance etc.
• All cracks and honeycombs shall be repaired prior to the waterproofing work.
• All points between the vertical and horizontal shall have an angle fillet formed with a non-cracking material mixed to a
trowellable consistency. Surface should be roughened and primed prior to application.
MIXING
• Pour the liquid contents (Part B) into a suitable sized pail and then slowly add the powder (Part A) while continually mixing
with a slow speed (500 rpm) drill and paddle. Continue mixing until a homogeneous, lump free mix is obtained.
APPLICATION
• Surfaces to be applied with NCL CEMPROOF 4 shall be saturated with clean water prior to application. Care should be
taken to avoid puddling. Extremely porous surfaces should be sealed before application.
• The first coat of mixed NCL CEMPROOF 4 should be applied at the rate of 1.0 Kg per M² by either brush, roller or spray and
allowed to cure prior to the application of the second coat.
• The second coat of mixed NCL CEMPROOF 4 should be applied t the rate of 1.0 Kg per M² at right angles to the first coat.
The uncured waterproofing coating should be protected from inclement weather and subsequently from physical damage
while exposed.
