Kestonit Termo

Levelling compound for floors with floor heating ( 3-50 mm)

Cement based levelling compound containing reinforcing fibres to be used for floors with floor heating. Suitable also for weak renovation subfloors before laying the floor covering.

Special features

contains fibres that will reduce the risks for cracks.
contains polymers that will give better elasticity and bond.
walkable after 4 hours.
flooring can be laid after 1-5 days depending on the thickness of the
layer at normal room temperature.
adheres to concrete, wood and various construction plates (Note the
correct priming).
good levelling properties
practically non-shrinking
moisture resistant
lowest application temperature +10°C
casein-free

Description

INSTRUCTIONS FOR USE

Add the floor screed powder gradually to cool (+10...+20°C), clean water, stirring simultaneously until a smooth, plastic mix is formed. Let the mix settle for about 5 minutes, then stir once more thoroughly. Apply smooth screed using a wide steel trowel. During the levelling shall be ensured that the cables / pipes will be properly filled with floor screed so that floor will be heated uniformly and can be ensured good bond between floor screed and subfloor. The first layer must be dry before applying a new layer. The drying of the floor screed must not be quickened by heating or ventilating.Too fast drying may cause hair cracks. Surface temperature on floor heating floors should not exceed +28°C. On larger surfaces shall b e paid attention for
necessity of movement joints (joints between walls and floors, inlets; in elongated spaces ( relation between sides over 2:1) movement joints distance max. 5 meter, division of large areas to minor parts).
If the temperature in the treated room is higher than normal, the relative humidity very low, or if the levelled floor surface is exposed to direct sunlight, we recommend that the floor is covered with a tarpaulin as
soon as it is dry enough to allow walking. The floor should be covered relatively soon after the hardening and drying of the floor levelling. Thus the overdrying of the surface is avoided and the risk of the cracks and weak
bond is eliminated. Suitable also for floors in secondary, light loaded rooms that will be painted, but not for example under the paint of the floors of garages or bathrooms etc. For the rooms, where water isolation is used, floor levellings should be applied under the watertight membrane. For floor heating floors in dry
spaces may even be applied watertight membrane between levelling compound and tiling to reduce stresses of clinkers caused by heat movements. Not recommended for areas permanently under water (e.g. swimmingpools). Note! Avoid excessive use of water!
