ClimaRoof KF-2
Waterproofing, flexible, leveling, 2-component cementitious mortar for flat roofs and horizontal surfaces
ClimaRoof® KF-2 is a waterproofing, flexible, leveling 2-component cementitious mortar with an advanced formulation that contains a complex of new generation resins specially designed to react with selected elastomeric and hydrophobic polymers, as well as with high-quality quartz aggregates.
It shows high adhesion to various types of substrates while providing excellent protection against moisture penetration and resistance to surface abrasion.
It is classified as a coating for surface protection of concrete according to EN 1504-2 & EN 1504-9:2008 (Principle PI protection against moisture penetration – Method 1.3, Principle MC -moisture control – Method 2.3, Principle PR - surface protection – Method 5.1, Principle IR – durability increase – Method 8.3)
Advantages
- Unique-innovative combination of waterproofing, flexibility and leveling properties.
- Excellent protection against moisture penetration.
- High flexibility.
- Strong adhesive properties on a variety of substrates.
- High surface strength and weather resistance.
- 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-2 has very good adhesion to standard structural surfaces (eg concrete, cement mortar, brick, cement board). Light soaking with water before use is recommended. It also has very good adhesion to substrates of acrylic waterproofing and decorative tiles, which are well anchored and without surface damage. On highly absorbent surfaces priming is recommended, using micromolecular acrylic primer Eco Dur Aqua by KRAFT PAINTS. On demanding substrates like: asphalt sealants, polyurethane liquid 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: ClimaRoof® KF-2 is spread on the surface of the extruded polystyrene thermal insulation boards ClimaRoof® KF-XPS, XPS Etics GF or ClimaRoof® KF-XPS Incline covering the entire surface without gaps, using a metal spatula (with pole or without). Application is completed in 2 layers crosswise. During first layer, reinforcement with anti-alkaline glass mesh ClimaRoof® KF-Net is obligatory, taking care that strips of the mesh must overlap by 10cm. After drying, a second layer of ClimaRoof® KF-2 is applied. Application thickness is 1-2mm per layer and maximum total thickness of the layers should not exceed 4mm. Application as waterproofing material: Apply ClimaRoof® KF-2 on the entire selected substrate without gaps, using a metal spatula (with pole or without). Application is completed in 2 layers crosswise. During first layer, reinforcement with anti-alkaline glass mesh ClimaRoof® KF-Net is obligatory, taking care that strips of the mesh must overlap by 10cm. After drying, a second layer of ClimaRoof® KF-2 is applied. Application thickness is 1-2mm per layer and maximum total thickness of the layers should not exceed 4mm.
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.
