SCOPE

• This Singapore Standard applies to
  ready-to-use elastomeric wall emulsion paint with
  waterproofing and repairing fine cracks
  properties for exterior use on masonry surfaces
  for both new painting and repainting works.

6
DEFINITION

• The elastomeric wall coating shall possess the
  following characteristics
• a) High-build functional coating
• b) Possesses waterproofing properties
• c) Is elastic and able to accommodate substrate
  and crack movements
• d) Allows permeation of water vapour from
  building
• e) Dry film thickness shall range from 100 -250
  µm

ADAPTATION

• Since there are no published and existing
  standards, this new Standard is based on a
  research project undertaken to develop a
  specification for an elastomeric wall coating
  emulsion paint for use under the climatic
  conditions of Singapore which is situated in the
  humid tropics.
• Some of the standards referred to were from
• JIS ( Japan Industrial standard )
• ASTM and
• our own SS 345

23
TESTS

• The methods are based on SS5, ISO and ASTM .
• 1. Colour - based on SS5 Part E3
• 2. Condition of Container - coating shall not
  show excessive setting and can be redispersed
  with a spatula to a smooth homogeneous state.

24
TESTS

• 3.Wet scrub resistance - to withstand 3,000
  cycles of scrubbing without exposing the
  contrasting colour of the leneta surface to a
  total length of more than 1 cm in the direction
  of the stroke .

25
TESTS

• 4. Accelerated weathering - Test for 1,000 hours
  exposure for no sign of chalking , blistering
  ,cracking and colour fading or other change in
  appearance .

26
TESTS

• 5.Alkaline resistance - Shall not show any
  blistering , wrinkling or lifting when examined
  immediately .
• 6.Sheen ( at 85º specular reflection) -Gloss
  measurement to comply to SS5 Part A3 TABLE 1

27
TESTS

• 7. Hard drying - drying time to comply to SS5
  PART A3 TABLE 1
• 8.Adhesion test( X - cut ) - To achieve a rating
  of at least 4A when tested in accordance to ASTM
  D3359.

28
TESTS

• 9.Algal resistance - There shall be no sign of
  algal growth using SS345 Appendix B test method.
