in accordance with the specified procedures.
3. For
scratch coating, use steel trowel or scraper to press the
putties in full strength, with special care to avoid uneveness
or exposure of the base. It is always best to start and finish
painting in a corner because it will eliminate any tap marks
that might occur. For roller coating and brush coating, proceed
following the routine steps.

1. The
surface of base layer is required in even, smooth, clear and
solid state as paint will not adhere to even the slightest
dirt residue. Shedding, pores, seams, oily stains, float dust
and chalky residue shall be eliminated.
2. For
steps, shallow areas and wading pools, we recommend sprinkling
white sand or marble dust (mixed in proportion of 1:3) on
the paint before it dries to make the area even and slip-resistant.
3. The
new coating shall leave untouched for a certain period before
second coat is applied. Generally, 28 days for cement mortar
surface and above 14 days in summer.
4. The water ratio of base layer shall not exceed 10%.
5. For
base layer with large water absorption, top seal treatment
is required.
6. The
base layer of outer wall must be top coated with alkaliproof
solution. However, base layer of inner wall will be coated
depended on its specific condition.
7.Acid etching is required on bare masonry surfaces like concrete
or plaster. Liberally brush the oxalic acid solution on the
surface to remove the alkali corrosion. Rinse off the acid
with clear water and top coat with alkaliproof liquid. If
the PH value of inner wall is higher than 10, alkaliproof
coat is necessary.
