It provides a fast-track screeding method for new concrete slabs, repairs in high-traffic commercial zones like supermarkets and hospitals, and screeds incorporating underfloor heating systems.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cp\u003eMapecem Pronto eliminates the risk of weak screeds caused by incorrect on-site sand grading or binder dosage errors. Because it is pre-blended, you only mix it with water to achieve high mechanical strength, reaching a compressive strength of over 40 N\/mm² in 1 day and over 62 N\/mm² after 28 days. Its rapid hydration chemistry binds mixing water internally, allowing the screed to dry to less than 2% residual moisture within 24 hours so you can lay moisture-sensitive resilient floor coverings, PVC, linoleum, and wood safely. It achieves a CT - C60 - F10 - A1FL classification under European Standard EN 13813, verifying its high compressive and flexural strength profile.\u003c\/p\u003e\n\u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 to 30 minutes pot life:\u003c\/strong\u003e Highly fast-setting mix that must be cast, tamped, and finished quickly.

Do not modify the water ratio under any circumstances, as this will compromise the final performance. Spread, tamp, and float the mix immediately; each batch must be fully placed and finished within 30 minutes of mixing. When work is interrupted, cut the screed vertically and insert 3 mm to 6 mm diameter, 20 cm to 30 cm long steel dowels spaced at 20 cm to 30 cm to tie the construction joints and prevent cracking.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Mapei","offers":[{"title":"Default Title","offer_id":47989251801280,"sku":"MAPECEMP\/20","price":34.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0507\/3630\/0224\/files\/mapecemp-pronto-screed-waterproofing-adheseal.png?v=1780813181","url":"https:\/\/adheseal.com.au\/products\/mapei-mapecemp-pronto-screed","provider":"Adheseal","version":"1.0","type":"link"}
