  • Ceramic tiles: 3-12 hours
  • Resilient and wood floors: 12-72 hours
  • For greater thickness and/or low temperature conditions, an extended waiting time could be required
• Compressive strength (N/mm²):
  • After 1 day: 20
  • After 28 days: 35
• Flexural strength (N/mm²):
  • After 1 day: 3.5
  • After 28 days: 8.0
• Brinell hardness (N/mm²):
  • After 1 day: 70
  • After 28 days: 100
• Resistance to abrasion: Taber Abrasimeter (Abrading wheel H22 disc - 550g - 200 rmp) expressed in weight loss (g):
  • After 7 days: 1.5
  • After 28 days: 1.2

Recommendations

• 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 on substrates subject to continuous rising damp
• Do not use as a floating screed - must always be anchored to a solid substrate
• Do not use on metal surfaces
• Do not apply at temperatures below +5°C

Application

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 4.5-4.75L 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 3mm to 30mm with a large metal trowel
• To minimise aeration a spiked roller can be used
• Can also be applied with an automatic pressure pump
• Due to its remarkable selflevelling 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 50m² approx

Cleaning:

• When fresh, Ultraplan Maxi 3230 can be removed from tools and hands with water

Storage and Safety Instructions

Storage:

• Ultraplan Maxi 3230, stored in a dry place, is stable for at least 12 months
• A longer storage (over 12 months) could determine a slower setting time
• However, the performances of the levelling layer at longer ages are not significantly modified

Safety Instructions:

• Instructions for the safe use of our products can be found on the latest version of the Safety Data Sheet (see 'Data Sheets' section above)
