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 Eco Prim Grip or Eco Prim T Plus prior to the application of Ultraplan Renovation Screed 3240. For marine use apply a thin coat of MAPEI Eco Prim Marine onto the clean dry surface without leaving pools of primer and the surface. allow the primer to dry (35-40 minutes) then apply MAPEI Ultraplan Renovation Screed 3240.
Preparing the mix
Pour a 25 kg bag of Ultraplan Renovation Screed 3240 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 of Ultraplan Renovation Screed 3240 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 of Ultraplan Renovation Screed 3240 mixed at any time must be used within 20 minutes
(at a temperature of +23°C).
Apply in a single coat from 3 to 40 mm in thickness. To minimise aeration a spiked roller may be used.
The self levelling properties of Ultraplan Renovation Screed 3240 will provide a surface ready to accept all kinds of floor coverings.
25 kg bags.
