    Description

    Keim NHL-KP 3.0 (Keim NHL Kalkputz Grob) - A dry bagged mortar manufactured to DIN EN 998-1, based on sand, lime (white lime, highly hydraulic natural lime) and hydraulic additives, as well as additives for a better processing and adherence. The strength complies with mortar category CS II or PII as per DIN V 18550.

    Keim NHL-KP 3.0 is a multipurpose lime-bound exterior and interior render for manual and machine application. It can be used as an undercoat and topcoat render for all interior, exterior and damp areas from the cellar to the roof.

    Suitable for rendering masonry of all kinds, rough-shuttered concrete etc and for use as topcoat render, this course grob can be used on any conventional undercoat render of mortar category CS ll - lV, but not on gypsum-containing, plasto-elastic or saponifiable substrates. It is particularly recommended for use in low environmental impact applications or for remediating historic structures.

    Preparation & Application


    Substrate Preparation
    The substrate must be solid, sound and free from dust and dirt. Undercoat renders have to be properly set. Particularly smooth surfaces need to be pretreated with a bridging coat, e.g. Keim NHL-KP 0.6 or Keim Universalputz. Strongly absorbing substrates have to be pre-wetted. When rendering wet masonry or very differing render substrate, a multilayer application of Keim NHL-KP 3.0 is recommended to reduce the risk of cracking. Very sanding undercoat renders need to be solidified by a pretreatment with Keim Fixativ (diluted with water 1:1 or 1:2).

    Application
    Keim NHL-KP 3.0 can be processed by hand; small quantities can be mixed with a blunger. However, processing with conventional commercial rendering and mixing machines makes more sense.

    Required water: approx. 6.1 - 6.8 l/sack. Minimum render thickness is 10mm when applied as an undercoat and 5 mm as a topcoat render.

    With render thicknesses of more than 20mm and under other unfavourable circumstances, apply multiple layers; sufficient setting time should be allowed for the undercoat render (1 day per mm of render thickness) before the final layer is applied (roughen previous layers). This is especially important at low temperatures, given the consequent delays in setting! On a highly absorbent substrate, the undercoat render should be applied in two layers wet-on-wet.

    Note
    Masonry with a bulk density of below 700 kg/m³ and/or a thermal conductivity of less than 0.13 W/mK should be rendered with lightweight (LW) renders (Keim Porosil-Leichtputz) according to DIN EN 998-1 (formerly DIN V 18550). Use special basement renders in basement areas.

    Application Conditions
    Do not apply and let dry below +5°C and above +30°C wall and air temperature. Do not apply in direct sun, wind or rain, and protect surfaces during and after application until the material is completely hardened.

    Drying Times
    A setting time of at least one day per mm render thickness is required before further coating. From then on, coatable after 10 more days. High air humidity and low temperatures can extend the setting time definitely. In case of a thin layer application or excessively fast drying process, the finished render surface has to be re-wettened once or more times.

    Finishing
    Keim NHL-Kalkputz-Grob can be coated with any thin-layer Keim finishing render and any KEIM painting system - it can also be tiled. For a subsequent coating with Keim Purkristalat, a layer thickness of 5 mm is required.

    Consumption
    Material consumption: approx. 1.3 kg per m² per mm thickness. Yield: approx. 26 l /sack = approx. 740 l /t

    Cleaning of tools
    Clean tools with water Immediately after use.
