Description
Is this the right product?
Use it for: High-flow, fast-setting, calcium-aluminate self-leveller with high compressive strength, for levelling, smoothing and repairing indoor floors in homes and commercial buildings before new flooring. It places easily to a very flat surface. Pours 1/16" to 1" (1.5 mm to 2.5 cm) in one lift. Tile, stone and moisture-resistant adhesives can go down after 3 hours, and moisture-sensitive flooring after 12 hours. Can be pumped. Goes over primed concrete, well-bonded tile, stone, VCT, and cement or epoxy terrazzo, epoxy moisture barriers, cement backer board, mortar beds, gypsum underlayments, engineer-approved plywood or OSB, nailed wood floors covered with glued and screwed 5/8" plywood, and uncoupling membranes like Mapeguard UM. Meets ASTM F710 and F2873, and ANSI A118.16.
Not for: Outdoors, more than 1" (2.5 cm) thick, or as the finished floor (it must be covered). Not over sheet vinyl, self-stick vinyl tile, LVT or LVP, glue-down wood, particleboard, Masonite, lauan, waterproofing or sound-control membranes, gypsum patches, moving joints or active cracks, or anything containing asbestos. Not for areas that stay wet, and it does not stop moisture coming up through a damp slab. Prime first, and keep the floor between 10°C and 32°C for 72 hours before, during and after.
Use instead: Priming concrete first: Primer L. Deeper than 1": Novoplan 2 Plus (to 2") or Novoplan DPL (to 4"). Damp slabs: put down Planiseal VS first, then prime with Primer X.
Levelling a floor and need it ready the same day? Ultraplan HFL is a high-flow, calcium-aluminate self-leveller that spreads easily to a very flat surface, and tile, stone and moisture-resistant adhesives can go down in just 3 hours. Pour from 1/16" to 1" in a single lift, by pail or by pump.
Made for indoor floors in homes and commercial spaces, it reaches over 6,000 psi compressive strength at 28 days. Moisture-sensitive flooring can go down after 12 hours.
22.7 kg (50 lb) bag · Coverage: about 52 sq ft at 1/8" or 26 sq ft at 1/4" · ASTM F710 and F2873
