Guidance

Mixing

Rødvig Jurassic Mortar is mixed in a compulsory mixing machine for 20 min. A whisk (500-800 watt) on a drilling machine can be used for smaller portions. First, water is poured in the tub, then the dry product. Mix until homogeneous. The amount of water, which is added, depends on what the mortar is for. Don't mix more mortar than you can use in about two hours. 

When manufacturing coloured mortar, mix 1 bag of Rødvig slaked lime mortar K 100/750 with the desired colour to 2 bags of Rødvig jurassic mortar Kh 100/400. If you only need a small portion, you can mix half of a bag of Rødvig slaked lime mortar to 1 bag of Rødvig jurassic mortar Kh 100/400.

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.
