1, Substrate Preparations:
1) Substrate must be free from grease, mould oil, rust, rusty
metal, wood peels, paints, plastics, loose particles, and
contamination on any traces of foreign materials will affect the
adhesion of Pinbang Base Skim Coat.
2) For spray application, substrate is to be moistened overnight
and also at the time before the commencement of spray operation. No
stagnant or frequent water flow on substrate is allowed immediately
prior to spray plastering.
2, Mixing and Installation:
1) Mix a bag of dry mix powder (20kg) with appropriate amount of
water by using an electric mixer for 3-7 min.
2) For hand application, add approx.5.2-5.6L (26-28%) of water; for
spray application, add 5.6-6L (28-30%) of water.
3) A pumping machine is used for the pumping and spraying of
Pinbang Base Skim Coat. This machine would only accept wet
materials and separate mixing is required.
4) Spray plaster with thickness of 2-4 mm can be applied in one
coat. Spray plaster with thickness of 5-8 mm can be applied in two
separate coats on the same day, namely the respective thickness of
the first coat and the second coat is 4 mm. The first sprayed coat
has to be 80-90% dried or touched hard before the application of
the second coat.
5) Each sprayed coat should preferably not exceed 4 mm. The maximum
thickness allowed to be applied on one day shall not be more than 8
mm in thickness over the same plaster area.
6) Wait for 1-2 hours to release air bubbles from the substrate.
Spray a thin coat of plaster with thickness of 1 mm for final
7) A European smoothening spatula with blade length of 300-600 mm
is used for levelling and smoothening of thin plaster, and forming
a smooth, flat and free of blemishes surface.
8) Plastered surface for painting or for wallpaper should be
smoothened by spatula. For better quality of paintwork, it is
recommended to wait for at least 3 days to reduce the alkalinity
(Details of the procedure please refer to our Method Statement.)
Natural air curing for Pinbang Base Skim Coat is enough. Water mist
is not required for interior application. However, water mist is
requested under extremely hot or dry condition. To obtain high
early strength, water mist curing is recommended at the first or
the second day.
