What does sandstone mean?

Sandstone comes under the category of clastic sedimentary rocks and is composed of sand-sized silicate grains. Sandstone comes in different varieties. This natural stone is primarily made up of feldspar, quartz, and several other minerals such as mica, clay, or calcite. According to experts, sandstone forms nearly 20-25% of all sedimentary rocks available on the earth.

Clastic rocks are not created by chemical changes or subterranean heat and pressure; rather, they are generated from pre-existing components.

Sandstone is deposited by rivers, seas, and arid areas to form sandstone. Groundwater minerals subsequently compress and gradually cement the grains together. Depending on their makeup and formation location, the resulting sandstones can have a wide range of colors. Tan, brown, red, yellow, grey, pink, white, and black are the most prevalent hues.

Common Mistakes To Avoid While Laying Sandstone Patio

It is easy to rush or take short cuts when laying a patio because it is a labor-intensive task. However, disregarding details will inevitably lead to subpar outcomes. Hiring a qualified and professional contractor to finish the job for you is undoubtedly the finest option. Before hiring a contractor, always request to view samples of their prior work; you don’t want to fall prey to dishonest business methods or subpar construction. When working with sandstone, the following mistakes are most frequently made:

  • Incorrect slab size: Your contractor ought to be able to provide you advice on what size slabs would be best for your area. While large slabs could prevent you from creating the arrangement or pattern you want, little slabs can make small patios feel even smaller.
  • Selecting the incorrect color: make sure to always inspect the color of wet slabs because wet sandstone can have a drastically different tint and may not meet your desired aesthetic standards.
  • Not laying a whole mortar bed; a complete mortar bed is necessary instead of spotting.
  • Slabs can be laid upside down; some will have a smooth side and a textured side. There will be loose joints if all of the slabs are laid with the textured side up. Inverting a portion of the slabs will result in loose joints and an uneven appearance.

Does sandstone need sealing?

Millions of years go by before sandstone is produced. It is made of a strong, weather-resistant material that won’t fade or degrade easily. But because it is a porous stone, it will take in dirt, moisture, and other things that will discolor it.

Although sealing sandstone is not necessary, it will help to prolong the appearance of a newly installed patio by preventing further deterioration. Additionally, sealant will stop spill stains, which can be very difficult to erase. There are sealants that enhance color and those that are invisible.

How can I maintain an Indian sandstone patio?

It is advisable to give your patio a wash whenever you have a moment. All you need to clean your slabs is a brush, soap, and water. The surrounding plants, foot movement, and dirt will all affect the color and texture of the patio paving. You can wash the stones with soapy water or dilute white bleach to get rid of the dirt.

It will take some elbow grease to remove mosses, algae (green), or lichens (black or white blotches) that have affected your patio. However, since chemical treatments like fungicides can cause the sandstone to become discolored, it is recommended to avoid using them to speed up the process.

Unless the paving features resin grouting, avoid jet washing your patio on high power as this can erode the stone and ruin the grout.

A sealed Indian sandstone patio needs to be resealed every one to two years in addition to routine maintenance. Repairing any cracked mortar should be done right away.
