Fosroc Cemtop GP Advanced Floor Underlay 18kg

Code: 40-FC630088-18KG
U.O.M. - Each
High performance floor underlay, self-smoothing, levelling mortar for carpet and tiles. Cemtop GP Advanced is designed as a heavy duty underlay which forms a smooth, hard surface for a variety of floor finishes including carpet and ceramic tiles. Cemtop GP Advanced can be used in conjunction with high build epoxy resin based systems in some scenarios, and can also be used in residential, commercial and light industrial applications. It can be used in conjunction with Nitoprime 330.

Details

Cemtop GP Advanced is designed as a heavy duty underlay which forms a smooth, hard surface for a variety of floor finishes including carpet and ceramic tiles. It has enhanced flow properties for fast and easy application, and can be applied 2mm to 50mm thick. Cemtop GP allows foot traffic within 4 hours in moderate temperatures. It can be overlaid with carpet in 24 hours, or vinyl in as little as 2 days.

Features:

  • Formulated for fast and easy application, with excellent ‘wet-edge’
  • Fast application by pump enables large areas to be completed in a day
  • Eliminates traditional sand cement screeds
  • Excellent adhesion to prepared substrates
  • Rapid hardening and curing allows speedy access for foot traffic and overlaying with carpet, vinyl etc.
  • Low VOC - 21.6 grams per litre
  • Able to be applied in thicknesses of 2mm up to 50mm without addition of aggregate
  • Ideal for:

  • Creating a smooth, hard surface for a variety of floor finishes including carpet and ceramic tiles
  • Residential, commercial and light industrial applications
  • New construction and refurbishment projects
  • APPLICATION

    Surface Preparation:

    The substrate should be clean, sound and free from loose material and contamination such as plaster, oil, paint and grease. New concrete should be at least 14 days old. Excess laitance should be removed by light scabbling or captive shot blasting followed by vacuuming to remove dust debris. Large cracks and holes should be filled. Prime the substrate with Nitoprime 330 prior to repair. The object of priming is to seal the substrate to prevent air release from the subfloor rising and forming bubbles and pinholes on the surface of the Cemtop GP Advanced. Primer coats must be allowed to dry before applying the Cemtop GP Advanced.

    Mixing:

    Each 18 kg bag of Cemtop GP Advanced requires the addition of 3.6 to 3.85 litres of water to produce a free flowing self smoothing consistency. Pour the mixing water into a clean mixing vessel. Add the powder slowly to the water, mixing continuously with a heavy duty mixer fitted with a suitable spiral paddle. Pour the mixed material on to the dry primed surface, spread with a trowel and allow to self-smooth. Roll surface with the purpose made spiked roller. Best results are achieved when the pouring and levelling is a continuous process.

    Placement:

    Cemtop GP Advanced has been designed for installation by pump. Refer to the Technical Data Sheet for further information. Thoroughly prepare the floor surface. Prime the surface with Nitoprime 330, diluted with water and allow to dry. Apply Cemtop GP Advanced to the required thickness onto the dry, primed surface. Cemtop can also be applied by hand.

    Clean Up:

    Cemtop GP Advanced and Nitoprime 330 should be removed from tools and equipment with clean water immediately after use. Hardened material can only be removed mechanically.

    Storage:

    Store in dry conditions to attain a shelf life of 12 months.

    Yield:

    One 18kg bag mixed with 3.6L water will yield 10.5L, which will cover 1 square metre at 10.5mm thick.
