Mapei Planicrete SP is a white, fluid SBR latex admixture for cement-based screeds, renders, thin smoothing layers and highly adhesive cement bonding slurries. Use it where the mix needs better adhesion, plasticity, thixotropy, water retention and workability.
Added to cement and aggregate mixes, Planicrete improves adhesion to the substrate and, after setting and hardening, increases compressive and flexural strength, abrasion resistance, impermeability and resistance to freeze-thaw cycles.
No. Always mix Planicrete with Portland cement or, where specified, Mapecem or Topcem.
Use Planicrete-modified mixes between +5°C and +40°C.
Mix for 2–3 minutes until smooth and even. Do not mix for more than 3 minutes in a concrete mixer because excessive mixing can entrain too much air.
Planicrete is specified for bonded screeds from 10 to 35 mm. Aggregate must be no larger than 1/3–1/4 of the screed thickness, with an 8 mm maximum.
Planicrete is available in 25 kg, 10 kg and 5 kg tanks and in 12 × 1 kg packages.
| Application | Why it fits |
|---|---|
| Bonded interior and exterior screeds, 10–35 mm | Improves adhesion and resistance; the TDS specifies 40–50 g/m²/mm consumption with 0–8 mm aggregate. |
| Floating screeds over 35 mm | Improves mechanical performance and workability; the TDS specifies 30–40 g/m²/mm consumption and at least two weeks curing. |
| Interior and exterior cement renders | Improves thixotropy, adhesion, impermeability to water and resistance to atmospheric agents. |
| Cement bonding slurries | Provides a highly adhesive slurry before screeds and plasters on existing cement surfaces. |
| Mortar for filling holes and damaged areas | Improves thixotropy, wall and ceiling application, adhesion and performance characteristics. |
| Abrasion-exposed cement mortar | The hardened modified mix has higher abrasion resistance for industrial floors, ramps and channels. |
Wear protective gloves and goggles and take the usual precautions for handling chemicals. For professional use.
Proper substrate preparation is critical for achieving the specified bond and performance of ARDEX Abacrete-enhanced screeds and renders. Failure to prepare correctly can lead to debonding and system failure.
Surface prep: Ensure surfaces are clean, firm, and free from dust, dirt, oil, grease, curing compounds, release agents, and any other barrier materials. The substrate must be strong enough to support the intended load.
Primer: ARDEX Abacrete acts as a bonding agent applied as a slurry coat. If rising damp is present, treat the substrate first with ARDEX WPM 300 before applying the ARDEX Abacrete slurry.
Surface prep: Remove all loose material, dust, and contaminants. Ensure the surface is sound and capable of supporting the render.
Primer: Apply an ARDEX Abacrete slurry coat to enhance adhesion before rendering. Ensure the slurry is still wet when the render is applied.
Surface prep: Confirm the membrane is clean, fully cured, and compatible with cementitious overlays. Follow the membrane manufacturer's guidelines for overlay application.
Primer: Apply an ARDEX Abacrete slurry coat to ensure a strong bond between the membrane and the new screed or render.
