CLASSIFICATION ACCORDING TO EN 13813 The material properties of UC Leveller Maxi comply with the norms referred to in this technical data sheet and are classified as C35-F7 A2FL-S1 according to EN 13813.
WHERE TO USE UC Leveller Maxi is used for levelling and smoothing new or existing substrates prior to the installation of carpet, carpet tiles, vinyl/LVT, ceramic tiles, natural stone or floating timber flooring. UC Leveller Maxi is especially formulated for areas of high build with controlled flow. UC Leveller Maxi is used in areas where resistance to heavy loads and traffic is required, along with an especially smooth surface. UC Leveller Maxi can be used in interiors in thicknesses from 10 - 100 mm as a bulk-filling underlayment compound. Because of its levelling properties and ease of pumpability, UC Leveller Maxi increases daily productivity and considerably reduces the cost of substrate preparation.
Some application examples · Smoothing concrete slabs. · For high thickness with low flow for easier control. · Smoothing for under-floor heating installations. · Smoothing over existing ceramic tile, terrazzo and natural stone.
TECHNICAL CHARACTERISTICS UC Leveller Maxi is a grey powder composed of special fast-setting and hydrating cements, specially graded sand, resins and special additives prepared according to a formula developed in the MAPEI research laboratories. UC Leveller Maxi has excellent self-levelling properties and cures rapidly. UC Leveller Maxi can be applied using an automatic pressure pump. UC Leveller Maxi is strong enough to withstand wheeled chair traffic. Each coat of UC Leveller Maxi can be applied in thicknesses of up to 100 mm without significant shrinkage that might cause cracks or crazing. Once completely dry UC Leveller Maxi has excellent compressive and flexural strength as well as resistance to impact and abrasion. Flooring can be installed once UC Leveller Maxi has dried (12 hours for light foot traffic and 1-3 days waiting time before installing flooring), depending on the thickness, installation conditions (e.g. temperature/ humidity), and choice of flooring.
RECOMMENDATIONS · DO NOT add more water to the mix once it has begun to set · DO NOT add any aggregate to the mix · DO NOT add lime, cement or gypsum to the mix · DO NOT use for smoothing in exteriors or for substrates subject to rising damp · DO NOT apply another coat of UC Leveller Maxi once the previous one has completely dried without first applying Eco Prim T Plus diluted with 2 parts water.
