How to seal Kandla Grey Indian sandstone in the USA?

Kandla Grey Indian sandstone in the USA

Mid-grey and Kandla Grey Indian sandstone in the USA are typically simple or have slight color changes. Subtle internal veining or differences in color between slabs may be used to identify color variation. Sandstones that are just gray cannot be given a color boost the way more vivid sandstones can. This article explains the several sealers that can be used to protect plain gray sandstones like Kandla Grey and others.

Kandla Sandstones that are gray or just plain gray contain different minerals than sandstones that are more colorful. Because of the iron concentration in the stone, they are more susceptible to rusting. Due to the lack of natural color to enhance, they cannot be particularly nicely colored.

For these reasons, it is advised to use an impregnating sealer that is invisible and breathable to seal Kandla Grey Indian sandstone in the USA. This sealant is superior to color-enhancing sealants or shiny top-coat sealants for sealing. With the more brilliant sandstones, such as mint fossils, raj, rainbow, or various sandstones, color enhancers work nicely. Simple sandstones don’t work well with shiny “wet appearance” sealers since they don’t bring out the color of the stone’s natural hue. Natural stone sealers guard against organic contamination and damage from frost. They also resist stains made of oil and water. Furthermore, some sealers will to some extent, change the color or impart a gloss.

Which sealer is used ultimately depends on personal preference. However, when sealing plain gray or Kandla Grey Indian sandstone, we think sub-surface impregnating sealers are preferable. Below, we go into greater detail about the reasons why.

Can I seal a plain Indian sandstone with a color enhancer?

With visible natural veining and earthy tones, sandstone is frequently a colorful stone. It can be sealed with a variety of sealers, including different kinds of color boosters. Any sandstone with clearly visible color or shading responds nicely to color enhancers. It’s critical to remember that the color must be visibly noticeable once the stone is completely dried.

An impregnating sealer that breathes and has a secondary component that slightly deepens hue or color is known as a color enhancer. Any exterior, even a little bit of colored sandstone works nicely with sandstone color and sealer intensifier. It might be used with plain gray or Kandla gray-sawn sandstones, but the problem with those is that they don’t actually contain any color.

In order to properly seal Kandla Grey sandstone, it is necessary to understand that you cannot push color or shade into natural stone that lacks it when dry. Due to this, a color enhancer should not be the first preference for sealing plain sandstones because you can be disappointed in the final result if there is no color change. The ability of a color enhancer to penetrate Kandla Grey Indian sandstone or other plain sandstones depends on the mineral makeup of the stone.


Color-enhancing sealers cannot change the color of Kandla Grey Indian sandstone in the USA. For the same reasons mentioned above, wet-appearance sealers that produce a sheen are not suitable.
