The crimsandstone blocks will mostly start to appear during the hardmode, on the underground Desert biome after it's consumed by the Crimson (Unless there is already an Crimson Desert present after the world generation). Just like other sandstone counterparts, such as Pearlsandstone and Ebonsandstone, it will spread the Crimson to nearby blocks, so take caution when placing it down. The same rule applies for the Hardened Crimsand Block.
