Dunlop General Purpose Construction Grout is an economical, high-strength cementitious grout that can be mixed to a dry pack, plastic or flowable state, giving one bag remarkable versatility across construction and repair tasks. The shrinkage-compensated formulation holds its volume as it cures, and strength development is impressive for a general purpose product – approximately 70MPa at 7 days and up to 85MPa at 28 days when mixed as a dry pack with 12% water.Where to use itSuited to indoor and outdoor projects wherever a dependable, high-strength grout is needed: packing under baseplates and machinery, filling voids, holes and pockets in concrete, bedding posts and bollards, grouting anchor bolts and starter bars, and general making-good around concrete and masonry. Application thickness ranges from 10mm up to 100mm.How to useStart with a clean, sound substrate free of dust, oil and loose particles, and dampen absorbent surfaces before grouting. Add clean water to achieve the consistency the job requires – dry pack for ramming into confined spaces, plastic for trowel placement, or flowable for pouring. Compact or rod the grout to remove entrapped air and finish with a steel trowel. A 20kg bag yields approximately 9.5L as dry pack, 10.3L at plastic consistency or 10.9L as a flowable mix. Varying the water ratio changes both workability and final strength.Important notesHigher water contents make placement easier but reduce ultimate strength – use the minimum water needed for workability. Maintain the 10-100mm thickness range and protect fresh grout from freezing and from rapid drying.Specifications Size 20kg bag Colour Grey Yield 9.5-10.9L per 20kg depending on consistency Compressive strength Approx. 70MPa (7 days), 85MPa (28 days) as dry pack Application thickness 10-100mm SafetyContains portland cement – wet product is alkaline and can burn skin and eyes on prolonged contact. Wear gloves, safety glasses and a dust mask when mixing, and avoid breathing dust. Read the Safety Data Sheet before use.
