Supplied in 25kg bags – bulk discount rates are also available for orders for more than 40 bags (pallet rate).
Mapei Ultraplan Renovation Screed 3240 is used for interior levelling, smoothing and infilling differences in thickness from 3 to 40 mm on new or existing concrete, screeds, stone, terrazzo and ceramic tiles, old and new timber floors, floor boards, chipboard panels, plywood, parquet for use in dry locations as an underlayment for floor finishes such as tile, stone, vinyl, carpet and wood flooring.
Mapei Ultraplan Renovation Screed 3240 is suitable where good resistance to loads is required, also for wheelchair traffic and underfloor and undertile heating systems.
Preparation of the Substrate:
The substrate should be solid, free of dust, loose particles, paint, oil, gypsum residues or other contamination that could compromise the bond. Timber substrates should be clean and solidly fixed, open joints should be sealed with Planiprep Skimcoat. Cementitious surfaces that are not sufficiently compacted must be removed or, where possible, consolidated with Prosfas or Primer EP. Cracks in the substrate should be repaired with Eporip.
The substrate should be primed with Mapeprim SP, Mapei Eco Prim Grip Plus or Mapei Eco Prim T Plus prior to the application of Mapei Ultraplan Renovation Screed 3240.
Preparing the mix:
Pour a 25 kg bag into a bucket containing 4.25-4.5 litres of clean water and mix with a low speed electric mixer to obtain an homogeneous, self-levelling, lump free mix. Larger quantities can be prepared in suitable mixers. After 2-3 minutes of slackening, the mix should then be restirred and then it is ready for use. The amount mixed at any time must be used within 20 minutes (at a temperature of +23°C).
