KEIM NHL-KP 3.0 Formerly KEIM NHL Kalkpuzt Grob

KEIM NHL-KP 3.0 is a ready-mixed dry mortar according to DIN EN 998-1 based on sand, highly hydraulic lime and hydraulic additives. Also combines additives for better processing and bonding. The strength complies with mortar category CS II or PII in accordance with DIN V 18550.

Best Uses

KEIM NHL-KP 3.0 is a universal lime-bound exterior and interior plaster for manual and machine application. Suitable for use as a base and finishing plaster for the entire interior, exterior and damp areas from the cellar to the roof. KEIM NHL-KP 3.0 is suitable for plastering all types of masonry, roughcast concrete, etc. As a finishing plaster, KEIM NHL-KP 3.0 can be used on all common base plasters of mortar category CS II - IV. Particularly recommended for use in building biology-oriented areas or for the renovation of historical buildings. Not suitable for application for gypsum renders, plasto-elastic coatings and saponifiable existing substrates.

• Excellent application properties
• Good machine processability
• Sound in terms of building biology
• Permeable
• Fire behaviour: non-flammable (A1)

Application

PREPARATION OF MATERIAL / MIXING & CONVEYING
Mix KEIM NHL-KP 3.0 with approx. 6.1 - 6.8 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.
These material consumption values are guide values for smooth substrates. Exact consumption values must be determined by means of test areas.

APPLICATION
Apply mixed KEIM NHL-KP 3.0 quickly with suitable tools in uniform layer thickness.

LAYERING SYSTEM
The minimum plaster thickness is 5 mm when used as a base coat 10 mm and 5 mm when used as a finishing coat. In the case of plaster thicknesses greater than 20 mm and other unfavourable circumstances, apply in several layers, whereby a sufficient standing time of the base coat is recommended before applying the last layer (roughen previous layers). This is especially important at low temperatures and thus delayed setting! If the substrate is highly absorbent, apply the base coat in two layers – wet on wet. Note: Masonry with an apparent density of less than 700 kg/m³ and/or a thermal conductivity of less than 0.13 W/mK must be rendered with LW lightweight plasters (KEIM Porosil lightweight plaster) in accordance with DIN EN 998-1 (formerly DIN V 18550). Use special plaster for base are. When plastering on damp masonry or on a very different plaster base, a multi-layer application of KEIM NHL-KP 3.0 is recommended to reduce the risk of cracking.

TOP RENDER
When using KEIM NHL-KP 3.0 as finishing plaster, the surface can be felted with a sponge board after sufficient consolidation. Free texturing or washing is also possible.

AFTER TREATMENT
KEIM NHL-KP 3.0 must be protected from drying out too quickly due to sun or wind, or kept moist if necessary.

FINISHING
KEIM NHL-KP 3.0 can be coated with all KEIM paint systems and covered with slabs or tiles. All KEIM finishing renders are suitable for overcoating KEIM NHL-KP 3.0 with KEIM Purkristalat. When applying a subsequent coat of KEIM Purkristalat, always observe the minimum layer thickness of 5 mm. Note: Observe standing times before recoating.

SETTING TIME
at least 1 day per mm render thickness (depending on temperature and relative humidity).When used as top coat render, allow to set for at least 5 days before coating. (If the standard rule of 1 day per mm results in longer setting times due to the layer thickness, the longer setting time must then be observed before painting).
