FOREWORD 0.1 This Indian Standard ( Part II ) was adopted by the Indian Standards Institution on 28 June 1967, after the draft finalized by the Painting, Var- nishing and Allied Finishes Sectional Committee had been approved by the Civil Engineering Division Council. 0.2 With a view to provide guidance with regard to the finishing work of wood and wood-based materials, the Indian Standards Institution is bringing out the- Indian Standard code of practice for finishing of wood and wood-based materials ( IS : 2338 ) which is being published in two parts. This part [ IS : 2338 ( Part II )-1967 ] deals with the painting schedules. The first part of this standard covers the operations and workmanship in finishing of wood and wood-based materials. 0.3 In the formulation of this standard due weightage has been given to international co-ordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the*field in this country. This has been met by deriving assistance from the following publications: N.Z : S.S, CP 5 Code of practice for painting. New Zealand Standards Institute. B.S.GP 231 : 1952 Painting. British Standards Institution. 0,4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*.

( Item v ) ] MERGING TYPE GLAZE AND STAINS B-1. MERGING TYPE GLAZE B-Ll Merging Type Glaze — ( which 'facilitates the blending of various colours after application ) is a transparent pigment bound with a medium having good flowing properties, thinned with volatile solvent. B-2. STAINS B-2.1 Stains are soluble fast dyes or transparent, pigments, dissolved or suspended in an oil, water or spirit medium. The consistency shall be such as to ensure complete penetration. iB-2.2 Stains are supplied either in liquid form ready for application or as powders to be dissolved in a suitable medium (water, spirit or oil) as indicated. If the medium is oil, driers and thinners may also be needed. B-2 .3 Water stains are solutions of vegetable dyes in water. Solution of certain chemicals in water, although not normally classed as water stains, are often used to darken wood, such as floor-boards. Potassium permanga- nate is a well-known example. B-2 .4 Spirit stains are solutions of spirit-soluble dyes in industrial methyfet- ed spirit. B-2.5 Oil stains may be solutions of oil-soluble dyes in linseed oil but usually, to give a wider range of colours, they consist of insoluble, transparent semi-pigments ground in linseed oil and thinned with turpentine or other solvents. Sometimes, wax is added to make the stain less penetrating. B-2 .6 Oil stains are sometimes supplied mixed with varnish and sold as varnish stains, but where it is desired to enhance and not to conceal the appearance of the wood, better results can be obtained by staining and varnishing sepalrately.
