It handles thicknesses from 3 mm to 70 mm in a single application without significant shrinkage, providing a smooth surface capable of carrying heavy loads, including wheeled chair traffic.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cp\u003eUC Leveller is a cement-based compound that cures rapidly to prepare uneven subfloors for floor coverings. Formulated with fast-setting cements, silica sand, and resins, the wet mix maintains high fluidity for self-levelling and can be placed using automatic pressure pumps to increase daily productivity on large areas. It complies with EN 13813 as a Class CT-C25-F7 levelling compound, developing excellent compressive and flexural strength to resist impact, abrasion, and structural load under subsequent floor systems.\u003c\/p\u003e\n\u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e3 mm to 70 mm thickness:\u003c\/strong\u003e The allowable single-coat range, providing bulk-filling capacity.

All curing and sealing compounds must be completely mechanically removed to achieve a minimum concrete surface profile of CSP #3. Cracks in cement substrates must be repaired first with Eporip.

Mix at 300 RPM with an electric mixer until free of lumps, let sit for a few minutes, and remix briefly. Spread with a large metal trowel or float, or apply by pump. If a second coat is needed, apply it as soon as the first coat can be walked on (approximately 3 hours at +23°C). If the first coat dries completely (exceeding 24 hours), you must prime with Eco Prim T Plus diluted 1:2 with water before pouring the next coat.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Mapei","offers":[{"title":"Default Title","offer_id":37551512453312,"sku":"UCLEVELLER","price":46.76,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0507\/3630\/0224\/files\/mapei-uc-leveller-self-levelling-interior-floor-adheseal.jpg?v=1763708591","url":"https:\/\/adheseal.com.au\/products\/mapei-uc-leveller","provider":"Adheseal","version":"1.0","type":"link"}
