Mapei Ultraplan Maxi 3230 extended information

Coverage: Approx 5m2 at 3mm thickness

Ultraplan Maxi 3230 is a grey powder composed of rapid setting and hydrating special cements together with selected graded silica sand, resins and special additives, produced to a formula developed in the MAPEI Research and Development Laboratories.

Mixed with water Mapei Ultraplan Maxi 3230 becomes a highly fluid and easily workable mortar, with perfect self-levelling properties, and high adhesion to the substrate and ultra-rapid drying.

It can be applied with an automatic pressure pump for areas over 100 m.

It can be spread in thicknesses up to 30 mm per coat without shrinkage, cracking or crazing, and develops very high compressive and flexural strength, as well as resistance to indentation and abrasion.

Mapei Ultraplan Maxi 3230 is ready to receive the flooring as soon as it has dried: the time required depends on the thickness of the levelling layer, the environmental temperature and relative humidity and on the absorption of the substrate.


  • Do not add more water to a mix which has already begun to set.
  • Do not add lime, cement or gypsum to the mix.
  • Do not use Ultraplan Maxi 3230 for exterior levelling.
  • Do not use Ultraplan Maxi 3230 on substrates subiect to continuous rising damp.
  • Do not use as a floating screed. Ultraplan Maxi 3230 must always be anchored to a solid substrate.
  • Do not use Ultraplan Maxi 3230 on metal surfaces.
  • Do not apply Ultraplan Maxi 3230 at temperatures below +5°C.

Application Procedure

Preparation of the substrate

Substrates must be dry, sound, free from dust, loose areas, paint, wax, oil, rust and traces of gypsum.

Cement-based surfaces not sufficiently solid must be removed or, where possible, consolidated with Prosfas.

Cracks must be repaired with Eporip.

Cementitious substrates must be primed with Eco Prim T Plus diluted 1:2 with water or Primer LT as required.

Anhydrite screeds must be mechanically abraded and can only be levelled with Ultraplan Maxi 3230 after being primed with Eco Prim T Plus diluted 1: 2 after the surface has been mechanically abraded.

On all non absorbent substrates apply Eco Prim Grip Plus after the surfaces have been cleaned with detergents and mechanically abraded. Level with Ultraplan Maxi 3230 after Eco Prim Grip Plus has dried completely.

Preparing the mix

Pour a 25 kg bag of Ultraplan Maxi 3230 into a bucket containing 4.5-4.75 I of clean water and mix with a low speed electric mixer to obtain an homogeneous, self-levelling, lump free mix.

Larger quantities of Ultraplan Maxi 3230 can be prepared in suitable mixers.

After 2-3 minutes of Ultraplan Maxi 3230 slackening, the mix should be re-stirred and then it is ready for use.

The amount of Ultraplan Maxi 3230 mixed at any time must be used within 30-40 minutes (at a temperature of +23°C).

Applying the mix

Apply Ultraplan Maxi 3230 in a single coat from 3 to 30 mm with a large metal trowel. To minimise aeration a spiked roller can be used.

Ultraplan Maxi 3230 can also be applied with an automatic pressure pump. Due to its remarkable self-levelling characteristics, Ultraplan Maxi 3230 immediately eliminates small imperfections (trowel marks, etc.).

When laying underfloor heating systems follow the regulations for the preparation of the substrate and the heating commissioning procedure.

On large surfaces follow all the movement joints present in the substrate and form control joints for every 50 m2 approx.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
