Foreword
GCC Standardization Organization (GSO) is a regional organization which consists of the 
national standardization bodies of GCC member states. One of GSO main functions is to issue 
gulf standards and technical regulations through specialized technical committees.
GSO Technical Council in its meeting number (52) held on 10/10/1443H, which corresponds 
to 12/05/2022, has approved the update of the translation of Gulf Standard GSO 1251:2022 
titled "Putty (water base) for interior use" in English language which was studied through the 
technical program of GSO Technical Committee for Chemical and Textile Products (TC01) in 
SAUDI ARABIA schedule . (Arabic) text is considered the official text in case of any conflicts 
between the two. This document will cancel and replace the Gulf Standard GSO 1251:2002.
