Outdoor sills stone - What is not suitable
You should not use marble. Because this stone is too sensitive for the outside. We do not recommend sandstone either. Sandstone is hard to keep clean. For that reason you should not use sandstone. Cast stone is not suitable for outdoor use. Only a few limestones are suitable for the outside. That's why most do not need it. Belgian granite, however, is an exception here. Anröchter Dolomit is also suitable for outdoor use. By the way, this limestone comes from Germany. Artificial stone, however, is not usable. Consequently, this stone may not be used outside. Quartz composite is also not for the outside. Due to the sunlight, he loses his color. That's why only external window sills should be used. Windowsill is also called window sill.
Exterior sills stone - The laying
A window sill exterior granite you have to move in any case with a slope. This can drain the rainwater. And in the water groove below. This protects the house wall. But water grooves should be at the top as well. This also keeps the window soffit dry. If you have at least 3 cm distance. Furthermore, window sills outside granite must be laid with mortar. For this we recommend Trass cement mortar. However, do not mix too much water. Before that, the wall parapet has to be cleaned. Same as the back of the windowsill. Also, the seal must be done. Trass cement prevents stains in the window sill exterior granite. On the one hand, there are no efflorescences.

After that you have to grout. There along the window. After the soffits. For this you can only use special silicone. And natural stone silicone. This prevents discoloration on the edge. But normal silicones should not be used under any circumstances. Because they contain vinegar. That's why there may be yellow spots. You can not remove them later, despite all the effort. Once the mortar is dry, he is tough. Then you can grout. Provided the surface is clean. Besides, she must be dry. Therefore clean again. In addition, it must not be too cold.
