Kiilto 60 Plus Pikalattiatasoite 10–200 mm

Fast setting and drying floor screed for castings, fillings and slopes in interior areas. Approx. 11 litres mass/bag. Low alkali, cementitious.

Special features

  • compressive strength > 30 MPa
  • walkable approx. 1–2 h
  • coatable after 16 h
  • coverage 1.9 kg/m²/mm
  • approx. 11 l mass / bag

Application

Special cement-based, fast setting and drying floor screed for castings, fillings and slopes at thicknesses 10–200 mm in interior areas. Carefully floated surface is suitable for waterproofing. For finishing the floor prior to the floor covering we recommend Kiilto levelling compounds.

1. Bonded floor/firm concrete subfloor: The substrate must be clean, solid and firm. Remove cement laitance, paint splashes, adhesive residue, etc., and brush or vacuum the floor thoroughly. Bond strength between the concrete subfloor and Pikalattiamassa floor screed is ensured by brushing a bond bridge on the floor before applying the floor screed. The bond bridge consists of a mixture of Kiilto 60 Plus (20 kg), Kiilto Fixbinder (1 l) and water (1.5 l). Kiilto 60 Plus is rubbed on the fresh bond bridge.

2. Floating construction/weak concrete subfloor and various construction plate substrates:
The cast is separated from the subfloor, for example, with Kiilto Valusuojakangas separation fabric or construction paper. The cast is detached from walls and inlets with separating boards/elastic sealant. The thickness of the cast shall be at least 50 mm reinforced construction (e.g., # 150 Ø 5). In underfloor heating floors, the cables/pipes are fixed in the concrete reinforcement.

Instructions for use

Strew Kiilto 60 powder slowly in cool (+10–20 °C), clean water by mixing with a power mixer until a smooth, zero-slump mass is formed. Start spreading instantly. The mixing can be done also with a concrete mixer (mixing time approx. 3 minutes).

Apply Kiilto 60 Plus evenly by using a darby float and/or a wide steel trowel. Rub the surface with a steel trowel. The cast must be dry before finishing with a floor levelling compound. 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, cracking and creating a weak bond. If the floor is not going to be coated within 2 weeks of levelling, it should be treated with curing agent or covered with plastic on the day following the levelling having been carried out, at the latest.

The waterproofing membrane/floor covering can be installed 16 h after spreading the screed; Keramix waterproofing membrane can be installed after only 4 h in optimal drying conditions

(20 °C, 50% RH). The screed will rapidly acquire good surface strength and will chemically absorb the amount of water stated in the instructions. Substrate's high moisture content and poor drying conditions will retard the curing process. With regard to floor covering installation and substrate's moisture specification, follow instructions given by RYL and the floor covering manufacturer. When assessing substrate's coatability, take the entire structure into consideration.

On larger surfaces the need for movement joints shall be considered.

Not recommended for floors that are going to be painted.

Not recommended for applications where the parquet will be glued down onto the subfloor.

In areas where waterproofing is used, e.g., bathroom floors, the cast should be applied under the waterproofing membrane.

Not suitable for areas permanently under water (e.g., swimming pools).

Note! Avoid excessive use of water!
