KEIM NHL-KP 0.6 Formerly KEIM NHL Kalkpuzt Fein

KEIM NHL-KP 0.6 is a ready-mixed dry mortar according to DIN EN 998-1 based on sand, lime (highly hydraulic lime) and hydraulic additives. Benefits from additional additives to provide better processing and bonding. Strength complies with mortar category CS II or PII in accordance with DIN V 18550.

Best Uses

KEIM NHL-KP 0.6 is a lime-bound fine plaster for manual and machine application and is ideal for use as a finishing plaster for interior, exterior and damp areas. KEIM NHL-KP 0.6 also serves as a bonding bridge for subsequently applied lime plasters. KEIM NHL-KP 0.6 is particularly suitable for historical renovation and refurbishment work as well as for biologically oriented residential areas. Suitable for use on all common basecoats, but not on gypsum renders, plasto-elastic coatings and saponifiable existing substrates.

• Excellent application properties
• Good machine processability
• Sound in terms of building biology
• Permeable
• Fire behaviour: A2-s1,d0

Application

SUBSTRATE PREPARATION
The substrate must be strong, dry, clean, sound and free from adhesion-reducing residues and must not be too absorbent. Separating substances, e.g. shuttering oil residues on concrete surfaces, must be removed by suitable means. Equalise strong unevenness with suitable material of the same type. Ambient and substrate temperature ≥ 5 °C during application and drying. Do not apply in direct sunlight or on sun-heated substrates. Protect surfaces from direct sun, wind and rain during and after application.

PREPARATION OF MATERIAL / MIXING & CONVEYING:
Mix KEIM NHL-KP 0.6 with approx. 7.0 - 8.0 L (specification per bag) of clean water with a power stirrer to a stiff-plastic consistency without lumps and allow to mature briefly. Do not remix already stiffened material with water. Application can be performed by hand, via continuous mixer or rendering machine.

APPLICATION
KEIM NHL-KP 0.6 is applied with a steel trowel and smoothed through to a good coverage in the first working step. When applied as a finishing plaster, the layer thickness is 2 - 5 mm. When used as a bonding bridge, e.g. on smooth concrete, apply KEIM NHL-KP 0.6 approx. 5 mm thick, roughen well,
allow to set for 1-2 days or apply a thin coat of KEIM NHL-Kalkputz-Fein (fine lime plaster) wet-on-wet. When used as a reinforcement layer, the layer thickness is approx. 6 mm.

REINFORCEMENT
Apply KEIM NHL-KP 0.6 evenly. Embed KEIM Glasfaser-Gittermatte (mesh), overlap 10 cm at the joints and overcoat wetin-wet with KEIM NHL-KP 0.6. Necessary cuts into the mesh are to be covered with an additional fabric strip. The system specific KEIM Glasfaser-Gittermatte (mesh) should be placed in the upper third and fully embedded. In the corner area of building openings, additionally embed a KEIM Diagonalarmierung.

TOP RENDER
When using KEIM NHL-KP 0.6 as finishing plaster, the surface can be felted with a sponge board after sufficient consolidation. Free texturing or washing is also possible. Free shaping , free modelling, spraying, slurrying and welding off is also possible. In the base area, use as a finishing plaster only if the presence of water is prevented by a roll of coarse gravel.

AFTER TREATMENT
KEIM NHL-KP 0.6 must be protected from drying out too quickly due to sun or wind, or kept moist if necessary.

FINISHING
KEIM NHL-KP 0.6 can be coated with all KEIM paint systems and covered with slabs or tiles. When applying a subsequent coat of KEIM Purkristalat, the layer thickness of 5 mm must be observed in any case. Note: Observe standing times before recoating.
