About this product
SBD Five Star Grout is a premixed cementitious grout developed for applications where an economical grout with good flow and strength is required. SBD Five Star Grout Standard is based on specially selected Portland cements, gradedaggregates and admixtures including a special form of carbon. This special formulation produces a grout which conforms to ASTM C827 Early Volume Change of Cementitious Mixtures. It does not contain iron, aluminium or other additives which produce non-shrink characteristics by chemical reaction. This eliminates any subsequent problems of dimensional instability, corrosion or staining. SBD Five Star Groutis designed primarily as a flowing grout but can also be used at a trowellable or dry pack consistency.

Features andand benefits Features benefits L Five Star Grout is shown to be effectively non-shrink by ASTM C827 Early Volume Change of Cementitious Mixtures which, unlikeother methods, measures expansion or shrinkage from time of placing. L Volume expansion to ASTM C827 when unrestrained is greater than 1·5%. L Precision grout suitable for use over a range of temperatures and site conditions. L Can be pumped, poured, trowelled or dry packed. L Does not contain iron, aluminium or other additives which have not withstood the tests of time. L Thermal expansion similarto that of good quality concrete. L Good flow properties.

Preparation
All surfaces should be clean and sound. Concrete surfaces must be free from any contamination including oil, grease, laitance and dust – and for maximum bond the surface should be roughened and presoaked with clean water. Immediately prior to grouting, remove free water including that inbolt holes or recesses. Metal surfaces must be free from rust, scale, oil or grease but removable metal shims should be lightly oiled. Ensure bolt holes are free of dust, water or any loose material. Formwork should be well sealed to prevent leakage.

Application
When pouring, the area to be grouted should be shuttered and a header box used to maintain a grout head of 150 – 200 mm during the pour.Machine mixing is recommended to achieve continuous pouring. For large applications Five Star Grout should be placed by pump and has been formulated to give a 35 minute working time. It does not contain metal particles; wear and tear on equipment is similar to conventional sand/cement mixes. Mixing and placement can be carried out between +5°C and +40°C. In service, Five Star Grout will perform...
