Direction for use
Dosage
Dose of 0.1 to 0.25 Itrs.. cc per
50 kgs bag of cement is usually sufficient
to produce self compacting and flowing
concrete. Optimum dose is best determined
by trial concrete mixes, otherwise
normal dose of 150 cc per 50 Kgs.
bag of cement is recommended.
Use the dispenser or measuring container.
Add Masterplast PL-1 to the mixing
(gauging) water. Stir well the material
before use.
Cleaning of
tools & Equipment
Tools and equipments can be cleaned
with water.
Storage and shelf life
Store the material at a cool &
dry place (at 25°C Temp. &
50% RH). Shelf life is one year. It
will freeze at (thawing) temperatures
but can be reconstituted by stirring.
Packing
150 ml, 1 Litre., 5 Litre, 20 Litre,
200 Litre.
Precautions
- Do not mix it with dry cement.
- Add to mixing (gauging
