data sheet tolerance for concrete surfaces

Method Statement for In situ Concrete amp General Concrete

A Answer If this is a concrete slab on grade check to ensure that the surface does not have a moisture problem prior to considering an opaque coating Tape several a 2 foot square plastic sheets to the floor use duct tape and tape around the entire perimeter of the plastic sheet Leave in place on the floor for two days To accommodate possible deviations in the finished levels of the structural concrete the recommended thickness is 40mm However the guidance in CIRIA report 1843 recommends that a tolerance of 177 10mm is adopted with a nominal depth of 30mm The specification for the base concrete surface should be compatible Jun 28 2016 nbsp 0183 32 1 Introduction The construction industry has grown over the last decades and resulted in improvements in company profits financial accessibility and increased commodities demand in Australia as it has in the United States and in other countries Despite its importance it has long been identified as one of the most hazardous industries in many parts Keep concrete not covered with membrane or other curing material continuously wet for at least 7 days after placing except wet curing period for high early strength concrete shall be not less than 3 days Keep wood forms continuously wet to prevent moisture loss until forms are removed Cure exposed concrete surfaces as described below Remove existing composition floor finishes and adhesive Prepare surface by grinding chipping self contained power blast cleaning or other suitable mechanical methods to completely expose uncontaminated concrete or masonry surfaces Follow safety requirements of ANSI A10 20
