Features & Benefits

• Applied before applying waterproofing products from the Plastimul line and is used to even out and improve their adhesion to the bonding surface on concrete or brickwork substrates (vibro-compressed concrete blocks, solid bricks, airbricks, cellular concrete blocks, lightweight bricks and pumice bricks).
• Concentrated, one-component, solvent-free bitumen emulsion produced according to a formula developed in MAPEI Research & Development laboratories
• When diluted, may be applied by brush or roller and is resistant to aggressive substances normally found in the ground
• After application, Plastimul C dries quickly and improves the adhesion of Plastimul waterproofing products applied later
• Adheres to dry and slightly damp substrates

Application

• Before applying Plastimul C on masonry, make sure the surface is perfectly clean, sound and sufficiently even. Carefully remove from the surface all traces of mortar protruding from between the bricks or blocks and fill any gaps in the joints with Planitop Fast 330 rapid-hardening, fibre-reinforced cementitious mortar, Mapegrout Thixotropic shrinkage-compensated, fibre-reinforced mortar or Mapegrout T60 if sulphate-resistant mortar is required. As an alternative, use sand/cement mortar admixed with Planicrete latex rubber for cementitious mixes
• Before applying Plastimul C on concrete make sure the surface is sound and perfectly clean. Remove cement laitance, loose and crumbling parts and traces of dust, grease, oil and form-release compounds by sandblasting or with high pressure water jets. Remove any gravel clusters and fill the gaps with Mapegrout Thixotropic or Mapegrout T60. Blend in the areas between foundations and vertical walls by forming a fillet joint made from Planitop Fast 330, Mapegrout Thixotropic or Mapegrout T60
• Dilute Plastimul C with water at a rate of 1 : 10 as indicated in the Technical Data Sheet and mix until completely blended
• Apply a coat of Plastimul C on dry surfaces with a brush, roller or by spray
• Clean tools with water while still wet. Mechanically or with thinners when hardened
• Coverage approx. 100-200 g/m², depending on the roughness and absorbency of the substrate

Limitations

• Do not dilute Plastimul C with solvents
• Do not mix Plastimul C with cement or admixtures
• Do not apply Plastimul C if the temperature is lower than +5°C or higher than +30°C
• Do not apply the product on old bitumen substrates or on substrates containing tar
