Each 25 kg pack contains a 22.6 kg bag of factory blended dry components and a 2.4 kg bottle of polymer gauging liquid. Its superior physical properties mean it can be laid much thinner than unmodified screeds, from 15 mm bonded. Bonded applications need Ronacrete Standard Primer (sold separately).\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\u003eBonded screeds from 15 mm (20 mm for very heavy duty)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eAbrasion resistance AR0.5 (special)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eCompressive strength over 55 N\/mm² at 28 days\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eFoot traffic after 24 hours\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eSlip resistance PTV 57 dry \/ 46 wet (steel float)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sw-benefit\"\u003e\n\u003cdiv class=\"sw-check\"\u003e​\u003c\/div\u003e\n\u003cspan\u003eInternal and external use, can be laid to falls\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eThe substrate must be sound (min. 25 N\/mm² compressive, 0.8 N\/mm² pull-off), dry (below 75% RH) and have an effective DPM; if not, use RonaFloor Epoxy DPM beneath the screed. Shot blast, plane or scabble to expose aggregate, vacuum, then wet thoroughly with clean water and remove surplus. Brush on Ronacrete Standard Primer (1.5–2 m² per kg) and lay the screed onto the wet or tacky primer. Mix for approx. 3 minutes in a forced action mixer or with a high powered slow speed drill and MR4 spiral paddle (not suitable for pumping). Compact, rule and close with a float or trowel; working time is approx. 45 minutes at 20°C. Lay over 40 mm wet on wet in more than one layer. Cure with Ronacrete Curing Membrane, or polythene for at least 24 hours. Heavy traffic after 3–5 days at 20°C. Check the manufacturer's datasheet before use.\u003c\/p\u003e\n\u003ch3\u003eCoverage\u003c\/h3\u003e\n\u003cp\u003ePer 25 kg pack: approx. 0.73 m² at 15 mm, 0.55 m² at 20 mm, 0.27 m² at 40 mm or 0.22 m² at 50 mm (11 litre yield; approx. 91 packs per m³).\u003c\/p\u003e","brand":"RONACRETE","offers":[{"title":"Single Pack (25kg)","offer_id":55608058249555,"sku":"RONA-WS15-25KG","price":38.14,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6720\/9043\/files\/ronafix-wearing-screed-15mm.jpg?v=1793696876","url":"https:\/\/shop.screedworks.co.uk\/products\/ronafix-pre-packed-wearing-screed-15mm-25kg","provider":"Screed Works Shop","version":"1.0","type":"link"}
