Product Description

Rødvig Jurassic mortar Kh 100/400 is a premixed hydraulic lime mortar, which only requires the addition of water before use. It consists of natural hydraulic lime (NHL 5) and kiln-dried quartz sand in the ratio 1½:3, grain size (0,0-0,3), (0-1,0), (0-2,0), (0-5,0) or (0-8,0). 

Field of Application

Rødvig Jurassic mortar Kh 100/400 is a particularly strong mortar well-suited for exterior work, rough-casting on ridge tiles and hip tiles, weatherboards, end of projections, footings, and is also well-suited as a basis mix for slaked lime mortar.

Guidance

Mixing

Rødvig Jurassic Mortar Kh 100/400 is mixed with water in a compulsory mixing machine or with a whisk for 20 min. First, water is poured in the tub, then the dry product. Mix until homogeneous. Don't mix more mortar than you can use in about two hours.

You can also use it on the construction site together with Rødvig slaked lime to produce these hydraulic mixed mortars:

Such a 2-component mixing method is particularly relevant when working with coloured mortars. Since the pigment has to be dissolved in water in order to achieve a uniform color, it's only the wet slaked lime mortar that can be delivered as a coloured mortar. It can then be mixed with the dry jurassic mortar component when preparing the mortar on the construction site.   

Execution

The underlying surface must be thoroughly cleaned. Loose particles and plaster flakes must be removed. To achieve the best adhesion when plastering and the like, the surface has to be rough and absorbent. Watering down the base is usually necessary when plastering. 

Limitations of Use

Ready-mixed mortars should normally be used within a few hours. Freezing point depressants or other additives should not be added. Once the mortar is mixed, you should no longer add binders, aggregates or water.

You should only work with the mortar when the temperature is above +5° and below +25°. If the mortar is used as a plastering mortar, the thickness of the layer should not exceed 2-3 times the maximum grain size per workflow. If the thickness of the layer is coming out too thick, there is a risk of cracking.

Storage

Dry products in bags should be stored in a dry environment raised from the ground on pallets with ventilation on all sides. This is so that condensation is avoided.
