Mapei Ultraplan Eco 3210 – Ultra-Fast Self-Levelling Compound (Interior)
Ultraplan Eco 3210 is an ultra-fast hardening, self-levelling compound designed to smooth and level interior subfloors from 3–10mm in a single coat. It delivers a durable, high-strength finish with very low emissions, making it ideal for busy areas and projects where you need floors ready quickly.
AI overview
Use Ultraplan Eco 3210 to level interior floors quickly (3–10mm) before installing most floor finishes. It’s particularly suited to areas with wheeled traffic, offers high compressive strength, and supports underfloor heating. Floors can typically be covered after around 12 hours (allow 24 hours for wood flooring). Mix with 4.8–5.0L water per 20kg and apply with a trowel/rake or via pump.
Why installers choose Ultraplan Eco 3210
- Ultra-fast set and dry: ready to receive many floor coverings after ~12 hours.
- Self-levelling and highly fluid for a smooth finish with minimal trowel marks.
- High strength and excellent resistance to loads, indentation and abrasion.
- Suitable for areas subject to wheeled traffic.
- Compatible with underfloor heating (including as a self-leveller over electrical UFH systems).
- Very low emissions (very low VOC) for improved indoor air quality considerations.
- Can be applied by automatic pressure pump (including long distances, where required).
Where to use
Designed for interior levelling and smoothing differences in thickness from 3–10mm on new or existing substrates, prior to installing floor finishes where strong resistance to traffic and loads is required.
- Concrete slabs and sand/cement screeds
- Rapid screeds and cementitious levelling screeds (including UFH-containing screeds)
- Anhydrite screeds (after correct preparation and priming)
- Existing cement, terrazzo, ceramic and natural stone floors (after correct preparation and priming)
Interior use only: Not suitable for exterior levelling or for substrates subject to continuous rising damp.
Application overview
1) Substrate preparation
Substrates must be dry, solid and clean, free from dust, loose material, paint, wax, oil, rust and any traces of gypsum. Remove weak cement-based surfaces and repair cracks before levelling.
- Cementitious subfloors typically require a suitable primer coat before levelling.
- Anhydrite screeds should be abraded to remove surface laitance, then primed before application.
- Ceramic/natural stone should be thoroughly cleaned, abraded, then primed for best adhesion.
2) Mixing
Add 20kg powder to 4.8–5.0L of clean water and mix with a low-speed mixer until smooth and lump-free. Allow to rest for 2–3 minutes, then re-mix briefly.
Pot life: use the mixed material within approximately 20–30 minutes (at ~23°C).
3) Application
Apply in a single coat from 3–10mm using a large metal trowel or rake, holding the tool slightly inclined to control thickness. The compound self-levels rapidly and helps minimise small surface imperfections.
4) Drying and floor installation
- Light foot traffic: typically after ~3 hours.
- Many floor coverings: typically after ~12 hours (temperature/humidity dependent).
- Wood flooring: allow ~24 hours before installation.
Cleaning
While still wet, clean tools and spills with water. Once hardened, removal is mechanical.

Important recommendations
- Do not re-temper with water once the mix begins to set.
- Do not add lime, cement or gypsum to the mix.
- Interior use only – not for exterior levelling.
- Do not apply on substrates subject to continuous rising damp.
- Do not apply below +5°C.
- If applying an additional coat after the first is fully dry, re-prime appropriately first.
