Grout, blitzzement, Plaster and masonry mortar are also available in small containers, sufficient for repairs. Who makes such repairs, should absolutely take into account the processing instructions of the manufacturer. Otherwise, mortar that is too wet or too dry will ruin all the work.
Used to repair: Grout, Sponge and rag, bucket, For Glättke, Chisel and hammer, Grout, To whom, Replacement stones, Brush and spirit level.
Carefully knock out the old mortar from the joint to be renovated with a hammer and a narrow chisel. Hit the defective disposal to the mortise. Carefully brush all loose mortar and dust out of the joint with the stiff brush. Mortar residues make grouting with new grout more difficult. Well watering the exposed joint is important, so that the grout does not dry out too quickly. Only then does the fresh mortar adhere sufficiently well. Grout is available in small containers and different colors for repair work. Mix only as much material as possible, how can be processed in a short time. Press the mortar from the smoothing trowel into the joint with a joint iron. First fill the vertical joints, then the horizontal, which determine the joint pattern. Immediately remove excess mortar with a rag and clean the stones with water. Acidify gray haze later with dilute hydrochloric acid.
Working with lightning cement
For little ones, Rapid repairs to masonry are ideal for quick repairs. The manufacturer's processing instructions are important. It is essential to observe the ratio of cement to water: If too much water is added to the ready mix, the mortar becomes too thin and the optimal holding force is not achieved. If there is too little water, the mortar hardens in a flash and can no longer be processed. For these reasons, all previous work should be done, removing the old mortar, the cleaning and watering of the wall and stone, be completed beforehand. Once the mixture has been mixed, it must be processed immediately. The setting time lasts at 20 Degrees Celsius outside temperature only five minutes. Cold water extends the open time somewhat, warm water shortens them. Attention: Flash cement has an alkaline reaction, That means, it is corrosive. People with sensitive skin or small injuries to their hands should wear rubber gloves when working. If a splash of quick-release mortar gets into your eye, it must be rinsed out immediately under running water, to avoid chemical burns.

Replace brick
Taking a broken brick out of a wall and replacing it with a new one is not difficult. But you shouldn't put off repairs like this for too long, for moisture and frost are the greatest enemies of masonry: Frozen water acts like a small explosive device. The greater the damage, the more expensive its repair.
The broken brick is smashed from the middle, so that the adjacent stones remain intact. Is the stone completely knocked out?, all loose parts are swept out of the hole. Then water the repair area and the new stone and mix the mortar. Put fresh cement in the hole and spread it. The new stone can easily be pushed into the opening on two thick pieces of wood. In this way you ensure the correct position of the stone. Then carefully pull out the two pieces of wood and fill in mortar with the joint iron. The vertical joints are first filled with mortar, then the horizontal ones. Finally, remove excess mortar with a rag or brush and wash the stone with a sponge.
Cut-off machine or drill – To change a brick, the joint can also be cut open with a power cutter or the stone can be drilled with a hammer drill. Then the stone can be easily smashed and knocked out. Always start in the middle, so as not to damage the neighboring stones.
