Sealing Sandstone is a clastic sedimentary rock with grains = clasts of 0.063-2.0 mm and a proportion of at least 50% sealant for sandstone grains of different minerals. The most common mineral is of course sealing Indian sandstone, which is relatively resistant to chemical weathering. So that the grains of sand become usable sealing sandstone paving, there is an interaction of different processes which is commonly referred to as diagenesis. The most important here are 2 processes, compaction and cementation.
Sealing Sandstone is a material that has many faces and has been used as a building material for a long time.
Sealing Sandstone usually has a high water absorption capacity. The disadvantage of sealing Indian sandstone from this is that it is also very sensitive to stains. But diffusion-open impregnations can help here. But impregnations are not a panacea either. On the one hand, the impregnation loses its effectiveness over time and has to be renewed, and on the other hand, no impregnation is acid-proof. Acid ingredients as well as acid rain cause damage to the seal/impregnation.
Clean and Sealing Sandstone
Sealing Sandstone doesn’t have essentially different from the products in terms of application. Of course, you should always follow the sealant for sandstone pavers instructions, but usually, the substances are already ready to use and can be painted, rolled and z. T. also be sprayed or injected. Depending on the condition of the sandstone surface, you should use a stone cleaner for a thorough cleaning before sealing.
