R4 is a light creamy coloured type of Vratza Limestone with darker and lighter yellow, orange or white flader.
R4 is a strong type of limestone and can be used for paving, cladding and other stone products for the interior and the exterior. Because of its extremely low water absorption, it is the best choice for your bathroom!
We recommend outside paving to be in honed, bush hammered or sandblasted finish. Installing R4 is really easy using all common ways for construction. Easy to be worked, this type of limestone is well-known and widely used by masons and artisans.
* Sealers are recommended as it is a natural stone product.
* Colour in natural stone varies.
