Conforming to BS EN 197-1 CEM I 42.5N, it provides reliable strength development and is the most widely used cement type in UK construction for floor screeds, structural concrete and general-purpose repair work.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cdiv class=\"sw-benefits-grid\"\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eBS EN 197-1 CEM I 42.5N compliant\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eReliable, consistent strength development\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eSuitable for screeds, concrete, mortar and renders\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eCompatible with all standard aggregates and additives\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eWidely available and cost-effective\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eCan be enhanced with rapid-drying additives (Topcem, Ronascreed)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eProven performance across all UK construction applications\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eFor traditional sand–cement screeds, mix at a ratio of 1 part cement to 3–4 parts sharp sand by volume. Add water sparingly until a semi-dry, earth-moist consistency is achieved. Lay, compact and level using standard screed practice. For concrete, adjust mix ratios according to the required strength class. Cure by keeping the surface damp for a minimum of 7 days. Apply at temperatures above +5°C.\u003c\/p\u003e\n\u003ch3\u003eCoverage\u003c\/h3\u003e\n\u003cp\u003eFor a typical 4:1 sand–cement screed at 50 mm depth, approximately 20 kg of cement covers 4–5 m².
