ClimaRoof KF-1
Waterproofing, adhesive, leveling cementitious mortar for flat roofs and horizontal surfaces
ClimaRoof® KF-1 is a waterproofing, adhesive, leveling cementitious mortar of high strength, designed with new generation elastomeric and hydrophobic polymers as well as with selected quartz aggregates. It ideally combines excellent adhesive properties between different types of surfaces and at the same time protection against moisture penetration.
It is classified as coating for surface protection of concrete according to EN 1504-2 & EN 1504-9:2008 (Principle PI- protection against ingress – Method 1.3, Principle MC - moisture control – Method 2.3, Principle IR – increasing resistivity by limiting moisture content – Method 8.3) and as screed CT-C16-F6, according to EN 13813.
Advantages
- Unique - innovative combination of waterproofing, adhesion and leveling properties.
- Great protection against moisture penetration.
- High adhesive properties on a variety of substrates.
- High mechanical strength.
- Advanced rheological characteristics with leveling properties.
- Ease of application (standing applicator).

How to Use
To ensure better adhesion, the surface is required to be flat, solid, dry, clean and free of dust, oils, salts, rust, loose paint and residues, swollen paints, etc. ClimaRoof® KF-1 has very good adhesion to standard structural surfaces (eg concrete, cement mortar, brick, cement board). Light soaking with water before use is recommended. On highly absorbent surfaces priming is recommended, using micromolecular acrylic primer Eco Dur Aqua by KRAFT PAINTS. On demanding substrates of asphalt sealants, acrylic or polyurethane sealing membranes, decorative tiles, etc. which are well anchored and without surface alteration, priming is recommended with Epoxy Aqua Floor Primer by KRAFT PAINTS with simultaneous application of quartz aggregates.
Application as part of ClimaRoof® System: For adhesion of extruded polystyrene thermal insulation boards ClimaRoof® KF-XPS or XPS Etics GF apply ClimaRoof® KF-1 to the substrate, with a metal spatula (with pole or without), covering the entire surface without gaps. Minimum application thickness should be from 3mm and maximum thickness up to 15mm (locally up to 40mm). Thermal insulation boards are then pressed onto the substrate to ensure universal contact with the mixture, following the substrate incline. The final surface of the thermal insulation boards must be completely flat, without gaps between them (<1mm) and in the form of intersecting joints. In case of ClimaRoof® Incline System, for adhesion of thermal insulation boards ClimaRoof® KF-XPS Incline on to ClimaRoof® KF-XPS or XPS Etics GF thermal insulation boards, ClimaRoof® KF-1 is applied with a metal spatula covering the entire surface without gaps. Then, ClimaRoof® KF-XPS Incline boards are pressed to ensure universal contact with the mixture.
Application as waterproofing, levelling or/and repairing material: Apply ClimaRoof® KF-1 to the selected substrate surface using a smooth or serrated metal spatula (with a pole or without), covering the selected surface. If necessary, level using a smooth metal spatula. The material should be coated with overlying layers (e.g. tiles, marbles, decorative microcemento coverings etc.) after 3-7 days, depending on the environmental conditions and after the material is dried in depth.
Immediately after the application tools must be cleaned with warm water and soap or a detergent solution. Remove as much material as possible from tools before cleaning.
