Forspec LEVELX is a high-flow, polymer-modified cementitious compound for smoothing and levelling prepared internal floors from 1.5 mm to 100 mm in a single application. It is suitable over sound concrete, screeds and saturated-surface-dry damp substrates when used with the appropriate Forspec primer. Once cured, it provides a smooth base for vinyl, carpet, timber, tiles, epoxy coatings or waterproofing membranes. The material may be pump or hand mixed and is walkable after approximately 2 hours at 23°C. In wet or external areas, a compliant waterproofing membrane must be installed over cured LEVELX before the final finish.
  • Applies from 1.5 mm to 100 mm in a single layer.
  • Walkable after approximately 2 hours at 23°C.
  • Covers approximately 4 m² per 20 kg bag at 3 mm.

Technical and product guidance for the item you’re viewing.
  • High-flow, polymer-modified cementitious floor leveller
  • 1.5–100 mm application thickness
  • Walkable after approximately 2 hours at 23°C
  • Suitable for pump application or mechanical hand mixing
  • Approximately 4 m² per 20 kg bag at 3 mm
  • Creates a base for vinyl, carpet, timber, tiles, epoxy coatings and waterproofing membranes
  • Not suitable as a final wear surface
  • 1. Confirm the substrate is structurally sound and fully cured. Mechanically grind, shot-blast or scarify to remove laitance, curing compounds, coatings, oil, grease, sealers and weak material, leaving a clean, open-textured surface.
  • 2. Repair static cracks with the specified Forspec epoxy repair system. Treat dynamic or structural cracking to the project design and carry all control, expansion and movement joints through LEVELX and the final floor finish.
  • 3. Test substrate moisture and select ACTFLEX 300 or the ACTFLEX EP 250 moisture-control system in accordance with the current Forspec TDS and project conditions. Prime porous, dense or smooth substrates using the specified primer or slurry-bond procedure.
  • 4. For standard levelling, add one 20 kg bag to 4.4–4.8 L of clean, cool water. Mix mechanically at 400–600 rpm for 2–3 minutes, stand for 1 minute, then remix briefly. Do not exceed the stated water ratio.
  • 5. Pour onto the properly primed substrate, maintain a wet edge and spread with a gauge rake, steel trowel or stand-up spreader. Pass a spiked roller through the wet material to release entrapped air, without overworking the surface.
  • 6. Protect the fresh layer from wind, sunlight, heaters, drafts and rapid drying. The application data states a +5°C to +30°C range.
  • 7. Allow at least 4 hours at 23°C before further levelling, patching or recoating. Re-prime hardened LEVELX before additional layers. The TDS lists 8–12 hours drying and 1 day before bonding, depending on thickness and site conditions.
  • 8. In internal wet or external areas, apply the required compliant waterproofing membrane over cured LEVELX before tiles or other finishes.

Forspec LEVELX FAQs

Can Forspec LEVELX be used in bathrooms and laundries?
Yes. LEVELX may be used as the prepared floor levelling layer in internal wet areas, but a compliant waterproofing membrane must be applied over the cured LEVELX before tiles or other finishes are installed.
Can LEVELX be used on balconies, podiums or terraces?
Only as part of a protected system. The TDS requires a compliant external-grade waterproofing membrane over the cured LEVELX before any final finish. LEVELX is not suitable as an exposed wear surface.
What substrates are suitable for LEVELX?
The TDS identifies sound, mechanically prepared concrete, screeds and saturated-surface-dry damp substrates used with the appropriate Forspec primer. Substrate moisture must be checked before selecting the primer system.
What coverage can I expect from one 20 kg bag?
Approximately 4 m² at 3 mm thickness. Actual consumption will vary with substrate profile, required thickness, surface irregularity and application waste.
How soon can LEVELX be walked on or covered?
The TDS states that LEVELX is walkable after approximately 2 hours at 23°C, with a drying time of 8–12 hours. It also lists a waiting time before bonding of 1 day depending on thickness, temperature and site conditions.
