Kiilto Plan Universal 4–30 mm

Self-levelling, pumpable floor screed for interior use. Low alkali. Cementitious.

Special features

  • pumpable
  • provides asuitable surface for floor covering
  • coverage 1.6 kg/m²/mm

Application

Pumpable floor screed on concrete bases prior to floor covering in interior areas. Recommended thicknesses 4–30 mm. Suitable applications are homes, offices and other public premises. For layers over 30 mm we recommend, e.g., pumpable Kiilto Plan Base levelling screed, Kiilto Lattialämmitystasoite levelling screed for floor heating or Maxirapid fast-setting cementitious adhesive. Suitable with common floor coverings such as stone and ceramic tiles, vinyl, linoleum, cork and textile. Also suitable with parquets, excluding glued down wooden floors (mosaic and block parquets). We recommend gluing mosaic and block parquets directly down onto a rigid concrete or plywood substrate.

The substrate must be clean, solid and firm. Remove any cement skin, old flaking screed, adhesive remains, paint stains and other impurities by sanding, milling or shot blasting. Vacuum the surface carefully. Subfloors are pre-treated with diluted Kiilto Start Primer (1 part primer/4 parts water) prior to application of the floor screed. Very porous substrates are primed twice. The primer is brushed onto the substrate 0.5–24 hours prior to the levelling work being carried out. (Avoid primer ponds.) Mark out the section to be levelled and prevent screed from getting into inlets with a sealing edge/sealant. Possible leaks are sealed with, e.g., mineral wool prior to pumping.

Instructions for use

Mix the powder with water using an appropriate automatic mixer until a smooth mass is formed. Use cool, clean water (+10 °C–20 °C). If the powder is cold, it can be mixed with warm water (+35 °C). Temperature of the screed and the substrate must be min. 10 °C to ensure proper hardening. Avoid temperatures over +25 °C. Higher temperatures will shorten the working time and the product's spreading properties will suffer. Ready screed is pumped onto the surface with a rubber hose in wide sections. The width of the section depends on pumping speed, thickness of layer, working conditions, etc. Sections over 10 metres wide are not recommended. Sections can be smoothed by using, e.g., a steel trowel. After pumping, clean the machines with clean water immediately. Visible section joints and possible air blisters can be removed by sanding after 2–3 days of levelling. Make as many movement joints on the levelling compound layer as there are in the substrate. The need for additional movement joints must be considered case by case. The drying of the screed must not be accelerated by heat or ventilation, since too quick a drying may cause hair cracks. If the temperature in the levelled room is higher than normal, the relative humidity very low, or if the levelled floor surface is exposed to direct sunlight, we recommend covering the floor with a tarpaulin as soon as it is dry enough to allow walking. The floor should be covered with a flooring relatively soon after it has hardened and dried. This will prevent the surface from over drying and cracking. Suitable also for floors that are going to be painted in secondary rooms with light traffic, but not, for example, in garages or for bathroom floors, etc. In areas where waterproofing is used, e.g., bathroom floors, floor levelling should be applied under the waterproofing membrane. Not suitable for areas permanently under water (e.g., swimming pools). Note! Avoid excessive use of water!
