    5. 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

    10. 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.
