Sand Blinding Floor: A Comprehensive Guide
When it comes to creating a durable and aesthetically pleasing floor, sand blinding is a technique that has been widely used for many years. This method involves applying a layer of sand to a concrete surface, which is then compacted and smoothed to create a seamless finish. In this article, we will delve into the details of sand blinding floors, exploring their benefits, application process, and maintenance tips.
What is Sand Blinding?
Sand blinding is a process where a fine layer of sand is spread over a freshly laid concrete surface. The sand is then compacted and smoothed to create a level and even surface. This technique is often used in commercial and industrial settings, as well as in residential areas, to provide a durable and attractive floor finish.
